Is it possible a similar patch would work for P2P on 3090s? btw, I found a Gigabyte board on Taobao that is unlisted on their site: MZF2-AC0, costs $900. 2 soc

Is it possible a similar patch would work for P2P on 3090s?
btw, I found a Gigabyte board on Taobao that is unlisted on their site: MZF2-AC0, costs $900. 2 socket Epyc and 10 PCIE slots, may be of interest. A case that should fit, with 2x 2000W Great Wall PSUs and PDU is 4050 RMB (https://www.toploong.com/en/4GPU-server-case/644.html https://www.toploong.com/en/4GPU-server-case/644.html). You still need blower GPUs.
- georgehotz 2y agoIt should if your 3090s have Resizable BAR support in the VBIOS. AFAIK most card manufacturers released BIOS updates enabling this. Re: 3090 NVLink, that only allows pairs of cards to be connected. PCIe allows full fabric switch of many cards.
- learnedmachine 2y agoThanks for the amazing work! I tried the driver with some 3090s (all of which show the 32G line with lspci -s 01:00.0 -v) and while torch says I have p2p access, I can't get it to work with anything as I get illegal memory access errors.
- Ratiofarmings 2y agoIn cases where they didn't, the techpowerup vBIOS collection solves the problem.
- cjbprime 2y agoDoesn't nvlink work natively on 3090s? I thought it was only removed (and here re-enabled) in 4090.
- qeternity 2y agoThis not not nvlink.

- davidzweig 2y agoUpdate, I checked with the case company, toploong, they say that board is a 5mm too big or so for the case.
