There are Xeon-based crypto motherboards on AliExpress with ~five x8 slots, I do sometimes wonder if those would work. NVIDIA Tesla K80/P40 24GB are on eBay for minimum $15 apiece. 120GB VRAM under $500 or so. Or maybe you could theoretically do a 96GB per node cluster with one x8 link for bottleneck free interconnect.
But it's likely never going to work, too many driver, compatibility, requisite Kernel development, and power issues, to name a few. Probably cheaper in the end to just go buy 5090 and rant about CUDA.
- genewitch 2y agoI had a couple of those boards. The full size slots aren't actually x8, because the CPU those boards support only have 24 PCIe lanes, and over half of them are just running USB, SATA, etc. The full size slots are so you can secure cards to the board, instead of running them zip tied to metal dish racks (like in the video i linked in my reply to your sibling comment: https://www.youtube.com/shorts/rTCInAXSzKA https://www.youtube.com/shorts/rTCInAXSzKA)
