Re: HOWTO: How I got my Radeon RX 560 to work on Ubuntu 20.0

I did the exact same thing this spring. The 470/570 (Polaris 10/20) cards are basically two 460/560(Polaris 11/21) GCN 4 dies combined. I've running three 460/560s for a while for folding. The crypto miners were selling them for a song and they do way better than older cards.

Re: Space Heater Build

Looking at your pictures, I thought I would note that you can control and monitor linux fold machines remotely/headlessly through the commandline: (1) Install ssh and login remotely. (2) Either run FAH as a service or use Screen (which lets programs run when you are not connected to the terminal) (3...

Re: Space Heater Build

The inefficiency of the gtx 460 and 480 is impressive. I am drafting a review of the radeon r5 240 and I thought they would be the worse choice possible for folding, but these are both slow AND inefficient. Apparently the folding performance value curve is U shaped, with actual computations on one e...

Re: Ryzen 9 3950x Benchmark Machine: What should I test for

Does the 1080Ti support PCIe 4 lanes? I would be curious how it scales about multiple faster OpenCL cards (both nvidia and amd). My experience with the 3900x is that some types of work units need more than one thread free to keep fast AMD cards fed on linux. Sometimes 1 thread is just fine feeding m...

Re: RAM usage Windows and Linux

I guess startup peak RAM usage is not so important as it can be swapped temporarily. As long as you have enough swap space available. There have been reports of some of the larger WUs exceeding 5 GB of VM during startup, and not working because too little swap was available. I just caught one WU a ...

Re: RAM usage Windows and Linux

Yes! Memory usage on windows and linux is similar. On my linux box with 8 gigs of ram, folding on the CPU and 2 gpus has periodically paged the GUI out to swap. Takes a few minutes to log back in. Enabling zswap ended up being a free and effective work around. It acts like the gpu workers need match...

Re: Ryzen 9 3900X @ 97C

I run my 3900x bone stock with PBO off using a Sythe Ninja 5 and case with lots of big slow fans and a rx 560. My office doesn't have good climate control, so it can get pretty warm before I stop folding for my own comfort. With 23 threads folding (1 set aside for GPU folding) I get T-die around 75-...

Re: HOWTO: AMD Radeon RX 550 on Debian 10 with rocm driver

Hopefully more success stories follow. I have been using the proprietary drivers without issue, but they are so painful to get installed and working.

Request for Clarification about Supported AMD GPUs

I have read a couple of places here that supported amd GPUs need double precision support, as noted by the columns in the wikipedia list of amd gpus. Because AMDs branding and hardware IDs can be confusing to everyone*, I was wondering if there was a more specific indicator? It seems like the a comp...
