I found a few ConnectX-3 cards (CX354a) for around $12 each to try P2P 40GbE with some of my lab stuff and desktop. Linux was no issue, but the Desktop (i5-12600k + Win11) was continual BSODs. I eventually tracked the issue down to CX3 not playing well with the i5's efficient-cores on Windows: https://forums.servethehome.com/ind...s-not-work-with-alder-lake-raptor-lake.39106/ .
Of course, in time honored Homelab Tradition, I can't let this defeat stand and I'll have to throw more money at it till I get it to work (even though I don't really need it...another time honored Homelab Tradition).
CX4 is supposed to work fine, but they go for about 8 times as much. Wondering if there's other older, non-Mellanox, QSFP+ options for cheap that work with Windows? Anyone with experience to share? TIA. Cheers!
