00:10:13 wut dis, https://x.com/fluffypony/status/1957791643232289246 00:10:19 https://github.com/monero-project/research-lab/issues/140 02:30:43 can we have a bridge to #monero-marketing? 03:10:21 @Cindy I can't make the bridge, but i copied your suggestion for marketing and request for the bridge into #monero-marketing. 03:10:58 thx 03:13:27 What makes you choose IRC over Matrix? Just wondering since I’m new to this stuff 03:13:54 because it's more stable and easier to use? 03:14:24 and without 'blinking lights' 04:30:16 Desperation from CfB. Many people are shorting Qubic, and I know someone in this chat who has made about $150k so far from shorting Qubic. Their scheme is falling apart and people are now taking advantage of Qubic. 04:30:38 No one cares about non-Monero shitcoins 04:31:32 Qubic is notable for their attempt to threaten Monero, not for their attempt to spew bullshit 04:31:42 lots of random scam tokens do that 04:34:34 If the price falls enough, their incentives will become almost worthless, reducing the weight of their attack. 05:53:17 There are some mining rigs for rent that only appear to run while being rented, like this one: https://www.miningrigrentals.com/rigs/322626/ 05:53:17 You might have to check "show offline" in the main list to see them, since they are offline while not being rented. It's also not possible to verify that they aren't secretly mining outside of the MiningRigRentals server while offline. 08:58:03 Is there any way to deserialize the raw_data that was constructed through wallet rpc transfer? 09:00:24 Hey guys really sorry if this is the wrong place. I want to trade my BTC for monero but dont really know how. Exchanges in my country dont have XMR. Can I get some advice on what ever "Atomic Swap" is, or a place I can learn? 09:00:25 Again, so sorry if im in the wrong place 09:01:16 Trocador.app 09:01:17 Bisq 09:01:19 Retoswap 09:01:21 Basicswapdex 09:02:47 Wow thankyou so much. Do you have a favorite, of these 3? 09:17:37 There is also unstoppablewallet which recently renamed to eigenwallet https://eigenwallet.org/download.html 09:19:56 Briefly Atomic Swaps are trustless, you either get your BTC refunded or the exact amount of XMR you expected. You have to download software that you need to navigate around to do this for you - and making sure that the offer you take has an acceptable exchange rate 09:28:01 Because you want to obtain xmr with a transparent coin (btc) you have to worry about its history - atomic swaps are the best way to do this ofc as there will be no way to have your funds withheld if source of funds is demanded which could occur on instant swap sites which sre most likely available for you 09:41:50 Some atomic swaps do not require specific software apart from web browser and monero wallet 09:48:21 ah true i forgot. Are there any BTC - xmr ones though? I only know of the BCH - xmr one @ https://axeswap.net/ from mainnet pat 09:52:46 Not sure you could do without a specific client when none of the chains have smart contract capabilities 12:16:29 I like haveno, but it’s not a replacement for local monero at least in my opinion. 12:27:10 it is different in how they operate 12:28:46 or work 12:29:29 it could be very well a better replacement than localmonero as with its design, could never be private or anonymous 12:32:29 LM was as private an anonymous as haveno 12:32:52 (Assuming you used it via onion or i2p) 12:34:40 well, close enough 12:35:10 I get that, but local monero was just so convenient and easy to use 12:48:44 sure it is very decentralized if you imagine so 12:48:52 ofrnxmr wasn't there a difference in who controls your wallet? 12:49:28 that is, did LM custody your wallet? 12:51:35 haveno's only decentralized in the network transversal 12:52:37 Nioc, honestly dont remember (and cant say, because it was proprietary). But i think it was something like they custodied a wallet that was protected by your password 12:53:20 Also @rando private and anonymous have nothing to do with decentralization 12:55:11 I never claimed LM to be decentralized. I said it haveno's privacy isnt much better 13:28:15 they can start logging and steal anyone's key whenever they want and it would be hard to tell if they are doing so 13:29:18 That would fall under non-custodial 13:30:10 I didn't use LM, but if anyone u had to create a wallet on LM to use it, right? 13:30:35 allegedly, LM could steal the funds frok your wallet. BUT iirc, LM claimed to not have access to your wallet 13:31:04 they could compromise this process from the start 13:31:06 LM gave you a subaddress to deposit to 13:31:15 trusting a website is always bad 13:31:18 Meaning, if you forgot your password, the wallet was locked permanantly. No way to know if true, since it was centralized & custodial 13:31:38 Nioc, they gave you either a) your own wallet or b) your own subaccount 13:31:48 yes 13:31:50 Because you could rotate subaddresses 13:33:16 anyways, LM is history now, I would suggest using our energy on improving haveno. 13:33:47 or the next big thing if ever 13:37:55 As much as i like haveno, as long as 2 randos can sweeo the orderbook, i find it hard to trust 13:39:04 the only current mitigation is to password protect your offers. But then nobody can take your offer, lol. 13:40:48 I think my idea was to only require funding the deposit, then trade oartner sends trade request, and when you accept, the rest of the funds are moved. if you dont accept, you can lose your deposit. If rogue arbitrator, you can only lose your deposit 13:40:59 Remember if a wallet is custodial. the money isn’t really yours until you withdraw 13:41:20 thats what custodial means 🫡 13:43:29 Downside: takes an extra 20mins. 13:43:29 Upside: you dont have to risk your whole offer 13:54:18 When local monero was around I never used the wallet that they gave me in my account. I only used wallets I controlled 13:54:49 ? 13:55:09 when selling coins, you had to use the internal wallet 13:55:33 When buying coins, you _had_ to use an external wallet 14:01:08 Yeah I never sold monero on local monero. I just bought coins from there 15:51:19 So what’s the conclusion of now the 51% attack and what are the countermeasures 15:58:38 The conclusion is that numbers dont matter 15:58:46 35 identifies as 51 15:58:58 Its 2028, and you can be whatever you want 16:04:54 there was no 51% attack 16:06:18 Yes there was 16:06:24 35 is the new 51 16:06:43 And im george washington 16:06:44 Its 2028 <<>> damn, I need to set my clocks 16:07:14 Yeah. I didnt know it was 2028 until a few mins ago. Monero us 14000usd bte 16:07:29 btw* 17:12:20 Don’t post any FUD pls 17:13:33 Tell that to someone who poated fud, sir/maam 17:14:56 14000$ for one Monero?? Why so bearish 17:15:28 140k before ye 2025 minimum 17:17:43 typo 17:36:15 lmao just figured out whatever Ubuntu LTS I originally installed on my system had dnssec explicitly disabled in resolved and that's why I've been getting DNS errors for years 18:54:41 They didn’t achieve a 51% hashrate, they got 53 out of 97 blocks at that time I believe. As for countermeasures. not much, because we’re sticking with pow and we just have to hope the price of monero goes up substantially to incentivize more miners to mine monero. 19:05:57 i wanted to estimate how it will affect my electric bill, just gotta find my meter maybe.. or i was thinking of buying a kill-a-watt to measure just the computer.. 19:08:44 But NGU is bad 19:09:45 also how will the price go up if it's not on many exchanges? arbitrage? 19:10:16 Adoption 19:11:15 Easy dex, bidirectional atomic swaps 19:12:20 See evm chain swap mechanics, if we even get half of the functionality it will be good 19:43:02 More like 53/120 w/ 23 orphans 19:43:52 Price goes up when we stop selling for peanuts 19:47:31 I was talking about the 51% claim from like a week ago that the news articles latched onto. 19:47:57 yes 19:48:25 Didn’t they orphan over 8% of blocks that day? 19:48:28 When they mined "51/100" blocks, ~20 of those blocks were reorged. There were actually ~40 blocks 19:49:06 20 blocks reorged is under 3% 19:49:37 Oh ok 19:51:01 think abt it like this. If you produce 10 blocks, and i also produce 10 blocks, there are 20 blocks 19:51:34 to say that i produced 10/10 blocks is lying. I produced 10/20 19:52:00 True 19:52:15 Even if, on chain, it shows that i produced those 10 blocks, it doesnt show that, during that period, there were 20 blocks produced 19:54:27 I mean even if Qubic did get 51% of blocks. It’s not really surprising, because they often get 30 to 40 percent of the hashrate pretty consistently. So it was only a matter of time that they would be able to achieve more than half of the blocks by mere chance. 19:56:05 A 51% attacker can do 100% of blocks 19:59:14 Yeah, because they could just orphan all the other pools pretty much, but the owner of Qubic just wants easy cash. so like most scammers he will choose the path of least resistance. He pretty much got what he wanted. he gets publicity, his coin gets pumped up and he gets to dump. Then he rolls in the sweet cash. 19:59:43 if he orphans all the other pools, it will kill monero's value 20:00:02 which is bad for his plan because he wants to use XMR to buy more QUBIC 20:00:33 True and that’s why I believe that’s not really his goal and he’s moving on to dogecoin anyway in a couple months 20:01:16 Got to feed the endless hype machine to pump his coin 20:06:27 Moving to doge is just hype 20:06:59 If you want to be famous, why would you mention attacking ltc? 20:09:18 I mean he knows it’s impossible for him to realistically go after dogecoin, but it doesn’t matter and when hype overrides people’s brains. People will just believe whatever he says no matter what. 20:09:29 their attacks are based on hype, clout and fud 20:10:14 No it isnt 20:10:21 dolus1, you'll need to trial and error, i'm not underclocking might get you a better hash per wat ratio 20:10:35 Doge miners are just opportunistic litecoin miners 20:10:37 not sure* 20:10:39 watt* 20:10:46 COME ON MATRIX SEND THE MESSAGE ALREADY 20:11:11 Doge, as a chain, is essentially deadcode with no real users 20:11:18 matrix needs 20 seconds to send a message 20:11:23 don't rush it 20:11:26 also dolus1 longevity is a factor for gpu because they are very complex, but CPU are literally indestructible 20:11:27 i will do that after it's built 20:11:57 also dogecoin is fucking dead 20:12:01 AM5 CPUs are designed to run with no longevity loss at 95°C 20:12:05 or so AMD claim 20:12:07 i'm 99% sure overclocking will reduce energy efficiency, sure i will get more hash rate but also use up far more kwh which i don't want to do 20:12:16 it's just a rugpull currency for elon musk at this point 20:12:29 and qubic wouldn't have much to ruin :P 20:12:31 yeah. Doge is garbage money 20:12:36 I mean sure, but with a dogecoin and litecoin are merged mined. it would be extremely difficult for him to take on both 20:12:48 No it isnt, @bart 20:13:00 The plan isnt for qubic themselves to mine doge 20:13:01 according to the xmrig benchmark site the 7950x will net around 22-24kh/s so that is what i will try to achieve with it 20:13:25 Its to get litecoin miners to accept pay in qubic to mine doge 20:13:29 lmao, these benchmarks are VEEEERRRRRRYYYYYYY synthetic 20:13:43 you can expect less 20:13:50 my current machine mines on average 5.5 kh/s (pc built in 2019 with ryzen 5 3600) so it will at least be a good improvement 20:14:11 Those benchmarks are like overclocking to the max 20:14:19 To try to get #1 on the leaderboard 20:14:22 and also sorts of complete autism rabbit hole 20:14:29 yeah literally benchmaxxing 20:14:44 22kH/s is what I achieve with my R9 9th gen 20:15:11 and that's really the top 20:15:28 I usually sit at around 19 20:15:30 Why so slow 20:15:32 My 3600 underclocked does at least 6 20:15:53 can you do damage undervolting? 20:15:56 it wasn't made for mining and has seen a lot of use 20:16:00 no 20:16:01 No 20:16:11 that's what I thought :p 20:16:15 You can go to low and have kernal panics 20:16:22 thanks for confirming though 20:16:23 Or fail to boot 20:16:24 never tried it 20:16:31 yeah at best you'll fuck the schedule clock 20:16:37 just reboot 20:16:45 Try it. These things are all way too high from factory 20:16:52 it's just fiddling in the bios as I understood it? 20:17:01 My sys is way more stable and runs cooler with a slight undervolt 20:17:19 YEAH BUT ACTUALLY LE TURBO GAMING MODE IS LE IMPORTANT OR SOMETHING 20:17:21 I dont remember how much i lowered it though 20:17:25 i'd like to undervolt to about 2/3 - 1/2 normal voltage and run a number of 7950 systems in parallel 20:17:50 gl with your endeavor 20:17:56 although at a certain point i might be better off just getting a single rig with an epyc 20:18:00 i'm not sure yet 20:18:11 epyc 100% 20:18:16 afaik epycs are the most efficient 20:18:22 yeah 20:18:30 good to know then i will probably look into getting one of those 20:18:34 They cost the most fir the hardware 20:18:39 but as usual, any good hardware is enterprise hardware and therefore very expensive 20:18:41 although the mobos for them are pretty expensive compared to normal ones 20:18:43 So roi is a longer 20:18:52 i don't care as much about roi 20:19:02 i want efficiency mostly and not too high consumption 20:19:19 so epyc it is i guess 20:19:26 from what I theoretically calculated they return most / watt 20:19:28 Idk about now, but isnt 3900 still one of the most efficient 20:19:30 At winter I don't want efficiency I want heat but ig different needs 20:20:03 as I see it the hardware cost is not the problem, it's the recurring cost for electricity that kills profits 20:20:31 Hardware costs more than power in the short-med term 20:20:33 last year's winter i put my pc under my bed just so that hot air goes into me during the night 20:20:38 Like 10000 for a server is worse than $35/mth 20:20:49 honestly unless you have free electricity via solar or something idk if mining xmr is profitable at all right now 20:21:07 you get it right 20:21:11 Its as profitable as the price you sell it for 20:21:15 it's only profitable if you have free electricity 20:21:22 yeah or this 20:21:34 i could install a couple solar panels to offset the cost 20:21:38 maybe 20:21:46 if you market sell to mexc while they have withdrawals closed, sounds like a you problem 20:21:49 big investment imo but I would be excited to hear about it 20:21:53 installing solar panels just to mine will not help 20:22:06 if you calculate the cost of that solar installation in 20:22:16 solution: steal the solar panel 20:22:22 solution: steal the hardware 20:22:25 solution: steal money 20:22:37 Borrow* 20:22:38 order ski mask + airsoft gun for FREE HARDWARE??? 20:23:16 just go near highway and wait until hardware falls of truck 20:23:49 so now i need to start looking for an epyc..... 20:23:52 🤔 20:24:04 maybe secondhand from a data center? 20:24:18 poke me in dm if you find one (you won't) 20:24:20 you can find good deals online if you look around a bit 20:25:15 Tell me these so called good deals 20:25:18 most of the time epyc cpus being sold online secondhand are really from companies being broke or individuals having the ability to sell it. Datacenter directly will never sell it to personal 20:26:22 epyc 7302 for €270? 20:26:27 maybe 20:26:54 disgusting 20:27:06 garbage tier cpu 20:27:16 you want at least 64 cores 128 threads 20:27:23 idk anything about epycs 20:27:30 barthman132: https://www.serversupply.com/PROCESSORS/AMD%20EPYC%2024-Core/2.3GHz/AMD/100-000000077_374915.htm 20:27:32 alright 64 cores it is 20:27:34 yeah i would have guess, that's fine everyone have its first time 20:28:38 I have never used it in real life but it seems balanced not to high power consumption, still good possible hashrate 20:29:00 mobo will be more expensive than consumer tier 20:29:38 for not so much gain 20:29:51 in hashrate 20:29:53 you can still go for a 48 core then 20:29:57 true 20:30:01 Epyc 9654 (96 core) for €3.550? 20:30:08 these EPYC-ROME series seem also nice 20:30:35 my brother in christ this is the last gen one, also double check i think this one have its max clock capped at 3GHz or something 20:30:38 Randomx like fast ram too 20:30:39 high mhz + tight timing make a real difference 20:30:46 you can't do that on epyc 20:30:51 if you can spend that money do it 20:31:08 stfu AMD will never make me buy a threaripper 20:31:11 are there epyc compatible mobos with ddr5 ram slots? 20:31:27 yeah, but timings are extremely loose 20:31:33 like JEDEC loose 20:31:41 well of course 20:31:57 for a RAM-intensive algorithm, faster RAM does mean faster execution 20:32:01 of course, but the slots are different, you'll be looking for RDIMM instead of UDIMM 20:32:07 your going to lost 25% of the hashrate just because of the RAM 20:32:09 different timing, different features, different capacity 20:32:32 tighter timing is as important 20:32:38 akshually sir wendell just released a video about the max pricey H14SSL-N from supermicro and it has 12 channel DIMM so it will be fast 20:32:45 because randomx is literally trashing 20:33:03 not when you have to change row and column at almost every single request 20:33:14 I don't listen to counterarguments sorry 20:36:26 ChadBird 20:36:27 you have to expect CL52 to 54 for DDR5 6400 20:36:50 Or is SyntheticChad 🤔 20:36:57 I prefer ChadBird 20:37:00 epic 20:37:18 i found another epyc here that seems pretty good for its price 20:37:19 I do too, even if it's less obvious 20:37:25 RDIMM i suppose? 20:37:30 a 9754 (128 core) for €3.230 20:38:25 JEDEC memories 20:38:27 That's for what theses things are rated for. 20:38:29 Except if they finally allow you to select XMP or EXPO profiles (or allow manual timing configuration). But I never saw that on a supermicro board 20:38:31 or other server stuff 20:38:34 €3.900 with VAT 🙄 20:38:41 still affordable i think 20:38:45 https://www.amd.com/en/products/processors/server/epyc/4th-generation-9004-and-8004-series/amd-epyc-9754.html 20:38:47 12 memory channels, max clock at 3.1 GHz and theorical max ram speed at 4800MT so I wouldn't call it a good choice 20:38:54 hmmm 20:39:26 I advice poking around with RavFX because he have much more money than me 20:39:32 4800mts need CL24 or less to be in the "potable range" 20:39:33 and therefore much more experience 20:39:50 CL24 DDR5 literally doesn't exist 20:40:20 By potable I mean equal or faster than a Pentium II with CL1 PC100 SDRAM as far as precharging, row and column changing, etc, etc 20:40:50 you wrote that on your 8086 powered computer 20:41:03 non, my 3950x 20:41:33 I hate 3rd gen 20:41:48 so I hate you 20:41:50 cordially 20:41:54 People just have no idea how memory work. 20:41:55 For the AM5 Ryzen, you want 6000MTs with CL30 20:42:00 that's what I call optimal 20:42:07 Also dual ranks and only two sticks 20:42:29 Give me a single manufacturer of 6000MT CL30 20:42:33 I'll wait 20:42:48 Hanzuei 20:42:56 https://www.corsair.com/us/en/p/memory/cmk32gx5m2b6000c30/vengeance-32gb-2x16gb-ddr5-dram-6000mt-s-c30-memory-kit-black-cmk32gx5m2b6000c30 20:43:03 Here first result on tha search engine 20:43:08 we are in 2025, not 2023 20:43:12 FUCK YOU 20:43:17 👍️ 20:43:24 That shitty timing iteration, append at literally every new memory generation 20:43:50 new memory arrive, it's all shit timing (initially) 20:43:51 Then it ramp up to the "optimal minimum timing" after a while 20:43:53 You'll release le DDR7 CL400 tomorrow morning and you'll be happy 20:46:26 I'm using CL54 btw 20:49:03 I'm using 3600-16-16-16-38 @ 3800-14-16-16-36-* 20:49:05 Yes they get toasty too, I have an extra fan aimed at the sticks lol 20:49:24 -* mean all other timing are manually set too but I won't reboot to look 20:50:54 Absolute memory 20:51:42 It's about the max I can do on that 3950x (the memory have to stay in sync with the infinity fabric, else it add latency) 20:52:01 and the infinity frabric don't run faster than 1900 21:01:31 https://matrix.monero.social/_matrix/media/v1/download/xmr.mx/kvdEzCBqMnMIOyhibcDUZLzT 21:01:33 https://matrix.monero.social/_matrix/media/v1/download/xmr.mx/LBrtjDcNEManUJrCCGAmkXTX 21:01:35 vs 21:02:15 https://matrix.monero.social/_matrix/media/v1/download/xmr.mx/azfdmFRQKwiQMeQEvbGCkoOv 21:02:16 https://matrix.monero.social/_matrix/media/v1/download/xmr.mx/kdIcoZuHrrBnxAltHUlVtIBk 21:08:02 ^ Memory bandwidth of said Epyc is like 3.5X more than my ryzen 21:08:24 damn so the epyc is buns? 21:08:31 Epycs are great 21:08:33 do i just go for a ryzen 21:09:10 But usecases matter. 21:09:11 For the price of the Epyc, you can get a lot of Ryzen (if the purpose is only for mining) 21:09:29 which ones are the most efficient in terms of hashes per watt 21:09:33 I use the Epyc for other shit. So mining I do on it too, but that's only a bonus 21:11:47 well, if you look at previous screens, That Ryzen use ~120W while the Epyc use ~180W while doing a lot less hr 21:11:47 But Epyc with more core might be plus or less similar (I think). 21:11:49 Like if you compare Zen 5 with 96 cores Epyc vs a 9950X 21:11:55 but have to find proper comparison 21:12:12 wait non 21:12:40 TDP of the 96 cores part is like 320-400 21:12:57 400 watts on 96 cores? 21:13:01 so I don't know, have to see how hash it produce to see if it's worth it 21:13:13 yeah, that's the rating look like 21:13:34 that's over 9 kwh per day 😟 21:13:45 So I think the Ryzen might use less as it will produce a lot more hr (per core) 21:14:07 But if you add many ryzen, take into account that you also have many board 21:14:15 i'm going for efficiency and trying not to break the bank so ryzen is probably best for me 21:14:23 so you have to find the mainboard that have the less integrated useless froufrou 21:14:34 and smaller as possible, like ITX or something 21:14:39 + a board for an epyc is 4x the price of a board for ryzen 21:16:10 And the Price of a 96 cores Epyc... 21:17:49 cursory google search shows me an epyc with 96 cores is about €3.550, while 16 core ryzen is about €700. if i wanted to stack ryzens for 96 cores i'd be looking at €4-5k which is more expensive 21:18:18 not to mention the mobos, psu, storage, ram 21:18:33 so yeah a single rig with an epyc is cheaper to build per core 21:18:35 and it's not cose 21:18:37 and it's not close 21:19:12 But it's going to produce less hr than the equivalent Ryzen core 21:19:13 which Epyc that was? 21:19:15 probably also far lower power consumption 21:19:20 9654 21:19:35 ok, yeah, that's the one I actually got my 350-400W figure 21:19:57 how much hash can i expect to get on it fresh? 21:20:02 If you go to the epyc route. 21:20:03 get 6400MTs memory that fit it, and you HAVE to fill all the channels 21:21:05 84K 21:21:13 sick 21:21:16 according to randomx benchmark 21:21:33 I think if you don't want to break the bank, the AMD Ryzen 7 5800X 8-Core gives you the best bang for the buck 21:21:35 i take those benchmarks with a pinch of salt 21:21:56 slower than my 6 years old Ryzen (per core) 21:21:57 as far as mining go 21:22:02 so if bench says 84k i will say 60-70k 21:22:12 dolus1 I ansered in the other channel, for the 7950X the mobo to get is B650M-HDV/M.2 AMD AM5 microATX Motherboard 21:22:17 I've been thinking about upgrading my ryzen 7 1700, was actually looking into that, if it's the one i'm thinking (last one with AM4) 21:22:23 hope no 21:22:27 alright 21:22:43 to get anything near the top bench scores you need to know how to tune the RAM subtimings 21:22:47 also factoring in energy usage? 21:22:59 yes 21:23:35 5900X better bang for the buck than 5800X 21:23:46 i can get ryzen 5800 for €140 21:23:47 smae cost for mobo, ram etc 21:23:49 very cheap! 21:23:52 (i think) 21:24:01 yeah it's one of the cheapest 21:24:06 look at total buils cost 21:24:06 84K on a 96 cores chip from 2025 = 0.875K per core 21:24:07 My 2019 cores Ryzen do 1.18K per cores 21:24:16 *build 21:24:25 at that price point im thinking more about the running cost than upfront lol 21:24:26 I wish we could adjust memory timing on Epyc 21:24:27 that is literally all the difference 21:25:27 memory timing on my 3900X = plus 30% HR 21:25:30 you can take the AMD Ryzen 7 9700X 8-Core Processor, which has TDP of 65 watts 21:25:35 it's a bit more expensive 21:25:35 the problem with such a cheap processor is you still need a dedicated rig for it (mobo, psu, storage, ram) 21:25:38 IIRC 21:25:59 you have to include one power supply and one motherboard and two memory sticks per ryzen too 21:26:01 TDP doesn't mean how much it will draw 21:26:11 assuming you PXE boot or something and don't need video 21:26:16 so there is a "golden ratio" of cpu price to price of all parts combined 21:26:19 of course 21:26:35 it mean how much they expect them to "dissipate" afaik 21:26:37 for example is it worth it to get a cheap cpu for 140 when the parts to support it cost another 300? 21:26:39 cost/HR 21:26:49 ^^^^^ 21:26:59 but CPU are 100% efficient so it's plus or less that (assuming your not using PBO shit 21:27:01 but I assume the cost of psu/disk/etc between 9700X & 5800X can't be that big of a difference? 21:27:11 maybe it is better to get a high end ryzen instead of low-mid end epyc 21:27:21 PBO? NFW 21:27:33 you don't need disks if you learn to PXE 21:27:37 static overclock and undervolt 21:27:48 Maybe I should spawn a CCS for a PXE mining system 21:27:58 I wonder if people want that 21:28:05 so everything in RAM or? 21:28:09 you can boot like ton of machine from the network and they just start to min 21:28:39 maybe ryzen 9 9950x? 21:28:39 it boot kernel+initrd from network 21:28:41 Then initrd mount a network from with NFS 21:28:43 Then you run the rest from NFS 21:28:45 BUT 21:28:49 you only need xmrig soooo, an initrd with xmrig would be fine too 21:28:51 it is the highest non threadripper ryzen cpu on xmrig benchmark 21:29:23 9950X is the fastest normal Ryzen yes 21:29:24 ROI for best cost for HR = long time :) 21:29:43 I have one on its way, curious ^^ 21:30:17 I have 3 mining rn that cost 0 21:30:54 2 others I built for other things with mining in mind 21:31:25 plus more 21:31:35 nice heat in the winter :) 21:32:07 that make it 1.7K per cores 21:32:09 (1.18K per core == my 3950x) 21:32:11 (0.78K per core == Epyc 9654) 21:33:08 Don't forget to price memory that have at **maximum** 10ns CAS 21:36:49 example of 10ns CAS :: 21:36:51 SDRAM PC-100 CL1 21:36:53 DDR-200 CL1 21:36:55 DDR-400 CL2 21:36:57 DDR2-800 CL4 21:36:59 DDR3-1600 CL8 21:37:01 DDR4-3200 CL16 21:37:03 DDR5-6400 CL32 21:37:05 If you can get CL digit lower, it's better 21:37:07 To calcule nanosecond CAS, do 21:37:09 CL * 2000 / MTS (example 32 * 2000 / 6400) 21:37:57 certain subtimings are more important that primary 21:38:06 *than 21:38:10 Usually the rest follow nioc 21:38:32 but yes, there important. Ideally you tune them manually, some other make big impact 21:38:43 Got a big boost when I increased the delay between the refresh cycle 21:38:50 trfc 21:39:18 don't use all your mem OC budget on primary is all imma saying 21:39:23 trfc are the delay between refresh cycle! 21:39:55 wait non, trfc is how much time you take to refresh the ram 21:40:04 and there are others which I can't remember rn 21:40:20 that one make a difference, along with the other one that define the amount of time you wait between each refresh 21:40:47 also setting hugepages is huge on linux, windows are auto set 21:40:54 is that a requirement or just increases performance? my laptop is apparently DDR5-5600 CL46 21:40:56 But yeah, the secondary timing are all imporant but usually stick rated for good CL will have also good other primaries and secondary 21:41:13 yep 21:41:21 It's impororant if your primary load is "ram trashing" aka RandomX 21:41:22 ^^ravfx 21:42:07 Laptop and thin PC are also often limited to JEDEC timing sadly 21:42:12 increase performance a​lexandre 21:42:31 so they will be less good at mining and there is no really good way to fix that, they just don't allow better for theses 21:43:09 Tighter timing increase performance but games benchmarks do show only a small difference, its really not the end of the world 21:43:18 But for Mining it make a huge difference 21:44:16 i see, would the "version" of the ram matter much? or just timing? (ddr4 vs ddr5) 21:44:44 For mining you want 10ns CAS equivalent (and hope the other timing of that ram you get is as good) 21:46:21 ddr4 vs ddr5 is cpu / system dependent, I have no experience with ddr5 21:46:45 I do have some DDR3 running rn lol 21:46:53 Speed is a thing but speed is there because DDR transfer data at the rising and falling edge of clock plus they burst (send what's at the next address) 21:46:55 Each new ddr Generation seam to double the amount they send in burst. 21:46:57 So newer generation is BETTER 21:46:59 BUT, you lost a lot of that performance if your primary use case consist of constantly changing memory row and columns 21:47:03 still gets surprisingly good HR 21:47:49 because while your ram can throw a lot of data back to back, if you request something in another location in the ram, the system have to wait for the ram to select that new location 21:47:51 Think about it as a big Excel sheet 21:48:46 everything on the right of the cell you select, on the same line, is blazing fast 21:48:47 If you ask something on the same row but not right after the cell you are at right now, it's slower 21:48:49 If you ask something on another row, it's a LOT slower 21:49:29 Timings define the performance of that mecanic 21:49:38 (the changing columns and rows thing) 21:50:27 While the speed of the memory and the ddr generation define how fast it is when you need to move a lot of data back to back (in the same row and using following columns) 21:51:16 Most software get huge advantage with burst because often program are in the same locations.. And game have bigs assets that are usually loaded back to back. 21:51:24 RandomX is... Random 21:53:32 ermm. actually, RandomX is random cuz it has random code 21:53:47 randomly-genrated code 21:53:58 It also seam to trash the memory... and a lot 21:54:04 it's why Timing make a huge difference 21:54:15 that interacts with randomly-generated RAM i guess 21:54:57 BTW : https://youtu.be/7J7X7aZvMXQ 21:54:57 If your interrested to know how memory work 21:54:59 Great animations 21:55:07 [How does Computer Memory Work?] 21:55:23 RandomX is literally its own CPU, which is very interesting 21:55:53 i don't think it has any illegal instruction combinations, anything is legal? 21:56:05 (since it's dealing with randomly generated code) 21:56:32 tell me if i'm dumb :P 21:57:09 Well, if it was doing illegal instruction, it would crash ;) 21:58:20 yeah the RandomX CPU would crash... to..... to something? 21:58:25 would it just halt execution? :o 21:58:35 halt execution 21:58:53 CPU would product a fault and the OS would take care of killing the process 21:59:20 no i mean the RandomX CPU :P 21:59:33 which is being virtualized inside the host CPU 21:59:48 You can test it. 21:59:49 you use DDR3 right? 21:59:51 compile something using -march=znver4 and run it, you see 21:59:53 through forms of either interpretation in high-level code or compiled into host code 22:00:02 I found an epyc 7763 processor for €1.333 22:00:04 oh wait no, that's the cat who use ddr3 22:00:07 bench is set at about 0.1 MH 22:00:42 The bench are widely variable 22:00:58 using MH makes it feel minimal 22:01:03 more that i'm looking at it, more bullshit it is 22:01:05 just say 100KH/s 22:01:13 yeah it says here using 2 cpu's 22:01:23 so more like 40-50 kh/s 22:01:25 ah there, two CPU, would make it like that yeah 23:38:41 Best OS to use to mine XMR? 23:39:54 Linux, just easier for that purpose 23:40:14 And you don't need to run a complete GUI just to mine XMR.. 23:48:24 Cindy: RandomX is designed so every possible sequence of bytes is valid code. https://github.com/tevador/RandomX/blob/master/doc/design.md#21-instruction-set "The interpretation of the instruction word bits was chosen so that any 8-byte word is a valid instruction."
