14:19:54 <paulio_uk> ... and for the next new build I have planned, going a bit more 'all in' than I usually would. Supermicro H11DSI; 2x Epyc 7B12; 128GB (16x8GB Samsung 2666Mhz); 2x 360mm AIO; 1200W platinum PSU; cheapest GPU (want to avoid using onboard display) - all crammed into a Fractal Design Meshify 2 XL case with as many fans as I can get in there.
14:31:21 <hyc> sounds great. after I get my solar panels installed I might consider getting some real server hardware here
14:41:26 <Inge> my threadripper lives in a Fractal Design Meshify 2 XL. not a bad case for an E-ATX board
14:45:36 <paulio_uk> the case will take a E-ATX/SSI-EEB with just enough space to comfortably fit in the radiators
14:46:09 <paulio_uk> I would have preferred a case that could take 2 360mm radiators exhausting out of the top - but they start to become rather custom and expensive at that point :(
14:48:34 <paulio_uk> works out to be around the £3000GBP  area for the build, which is about what I spent on the 5950x and 7950x builds. Probably get some parts from Amazon using Monezon as I don't think my bank balance can handle it all and still leave me with enough backup for emergencies
15:20:00 <sech1> Nice build. If you're going for peak h/s/watt, you need to aim for 600 watts at the wall (50% of PSU's max). This should be around 85-90 kh/s which is achievable by 2x Epyc 7B12
15:52:45 <gingeropolous> ugh. i gotta tune my miners more hardcore. 
21:12:46 <paulio_uk> my goal for the epyc setup is 80kh/s, with a preference for 85kh/s+ - will probably take some tweaking of the memory timings to get it in the sweet spot
21:16:34 <paulio_uk> theres a couple of options for the memory choice, I can pay a little bit more and get 128gb in 16GB sticks, same speed. (CL15 I believe)
21:17:57 <paulio_uk> Once I've mined enough to buy my Lambo, I can't think of anything I'd need a 128core server to do that'd require more than 128gb of memory, but if I went down the 16GB stick route, I'd have space for upgrading - but time will tell
21:36:28 <sech1> 128/16/2 = only 4 memory channels per CPU. It might be enough to get 85 KH/s, but not guaranteed. Better got with 8 channels
21:36:34 <sech1> *go
22:27:28 <paulio_uk> good shout. 8gb's it is
22:35:30 <sech1> Although I saw this: https://youtu.be/Ie10nZ-wcl8?t=385 so you might be fine with 4 sticks per CPU
22:41:43 <paulio_uk> damn he topped the ratings for that cpu
22:44:32 <paulio_uk> oof a dual 7743 is about a £4000 build
22:49:44 <paulio_uk> he has it on a 1KW PSU too - could tweak my spec a little bit, but then I'm going AIO so a little bit extra juice can't hurt
22:51:03 <paulio_uk> VRMs seem to be an issue when they're under serious load, might need to 3d print up some kind of directional ducting to get some airflow going down onto them
22:52:05 <paulio_uk> also read notes about the larger capacity the memory, the higher the temps they get too. 8GBs should be sparely populated enough to not overheat
23:07:39 <sech1> 4 sticks per also consume less power than 8 sticks, and if you don't try to reach max hashrate, 4 should be enough
23:08:36 <paulio_uk> I'll be sure to tinker with it when I eventually get around to ordering it
23:09:32 <paulio_uk> just don't want to get lumped with a few hundred £ of spare parts if I need to upgrade/tweak it - though I suppose this could just be the start of my rig expansion into the epyc world
23:10:02 <paulio_uk> I need a bigger house :|
