Re: Cheap EPYC Rome 7742 and 7402 for sale.

I was just coming here to post this after seeing it. I sent them a PM asking if those EPYC 7742's are vendor locked to Dell or otherwise. The 24 core one would probably work well for my 'multiple GPU crunching machine' build even.

That is pretty incredible, thank you for the detailed explanation! Just needing to use a web browser for the remote GUI makes it even better than I expected.

Re: Multiple GPU build ideas

This should work. I'm going to mess around with it more once a few of the remaining parts come in, but the motherboard and CPU arrived today. I just booted up the board with just some random DDR4 non ECC RAM I had sitting around and was able to boot into bios and it detected the RAM, showed the corr...

Re: Multiple GPU build ideas

Does anybody know if the 'estimated time per fold' in Folding@home updates as the task runs or is it an average? I'm just wondering if it would be reasonable to start a task, run it for 20-30 minutes and then change the PCIe bus speed, run it for 20-30 minutes and see if the TPF changes.

Do AMD cards not report PCIe bus bandwidth? I could have sworn it would show in GPU-Z on Nvidia cards, but I'm testing with an AMD Vega56 right now since it what was already in the PC and it doesn't show. I think I should be able to test this pretty easily now that I've looked into it a little bit. ...

Re: Multiple GPU build ideas

I appreciate the insight StefanR5R . That makes sense - I would do an initial run though of all projects, noting their bus usage and then would only need to test the ones at x1, x4, x8 that I've identified as using a lot of bus bandwidth. I could probably just test my most powerful AMD card and my m...

Re: Multiple GPU build ideas

That's a bummer, but I appreciate the reply. It would be fairly daunting to try to test each BOINC GPU project at x1, x4, x8, etc. Especially since x4 may not bottleneck a 2070 but potentially would a higher performance card like a 3070 or 3080. I have a strong feeling that in about 2 years there wi...

Re: Multiple GPU build ideas

I'm not sure how feasible this idea is without spending a ton of money unless I scale down the number of GPU's per machine. It sounds like I could do 6 GPU's at x8 with a 1st gen threadripper.
