x5 for 605$ on aliexpress .... is it a scam somehow

possible

I've seen plenty of other scams there

<h​bs:matrix.org> ask the seller for photos of the interior of the beast, maybe we'll learn something or maybe we'll have a good laugh

Well I found an X5 far sale at £1275.70 which is around 1/3rd the retail price, however they only accept payment in BTC, USDT, Western Union or Moneygram so.... I'm giving it a miss :P

seeedstudio.com/Sipeed-MAIX-I-modul…4-AI-Module-K210-inside-p-3206.html i was checking a local supplier for SoC category, and i saw this note on the product page "28nm process, dual-core RISC-V 64bit IMAFDC, on-chip huge 8MB high-speed SRAM (not for XMR :D), 400MHz frequency (able to 800MHz)".

funny little note there

Probably because I don't see any memory modules on the board, so 8 MB SRAM is all it has

amazon.in/Gona-Shop-Module-RISC-V-inside/dp/B09462ZZHW all the shops copied their texts, so XMR note is everywhere. sech1 yeah it seems to have only this onboard, 2MB for "AI stuff" 6 MB is general purpose RAM

we've left our footprint on the computing world ;)

I ordered the Sipeed Lichee 4A. the company says the cases will be in stock in a week

hyc: one of these? aliexpress.us/item/3256805838196196…210%21AS&curPageLogUid=Nj6Wi3nM89SZ

Wow, that's hardware porn p2pool.io/u/7d34d185e753779b/image.png

nice little raspberry pi compute stack :P

I have a feeling thats what the inside of the X5 looks like, only with the Lichee 4A compute modules

I wonder what the IO comparison between the lichee 4a and pi compute modules is like... could they have just repurposed the pi carrier boards?

What I posted is lichee boards, not pi

jtgrassie: nope, just a single. aliexpress.com/item/1005005532736080.html

no point in going all-in until I have an actual JIT that can give us perf figures

and I'm still annoyed at the lack of hardware AES

damn my bad, did a similar image search and it came up with the pis

safe to say thats roughly what half of the inside of the X5 looks like then, if they're quad core, thats a stack of 35 of them, ~600h/s per core. thats about 84kh/s worth of A4s

7 slots, quadcare, 28 cores per stack

@hyc so it's xuantie c910 cpu?

yep

^ not enough cache for RandomX

enough for 32cores though, so could have some spare to using it for non-xmr stuff :)

shame about the P550 chip from SiFive, barely any L3 cache (4mb on a 4 core chip)

ARM boards are even worse, it's hard to find anything with more than 1 MB.

yeah, not even on the ARM server chips

Apple M1/M2 maybe

If we're paying apple prices, may as well look at Epyc :P

xmrig.com/benchmark/55ZwTR yup think its time to restart Windows

meh, booted up into debian to do another benchmark, damn secureboot giving me hell with the msr module :/

since I can't be bothered to sign it and load it, and have nothing but hell with secureboot turned off, guess I'm stuck with a maximum of 19kh/s in debian :|

however I did squeeze 20kh/s out of a freshly restarted windows 11: xmrig.com/benchmark/2BHpnh
