Another note about OCing multiple GPUs your desktop entry should look like this [Desktop Entry] Type=Application Exec=nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUTargetFanSpeed=***" -a "[gpu:0]/GPUGraphicsClockOffset[4]=***" -a "[gpu:0]/GPUMemoryTransferRateOffset[4]=***" X-GNOME-Autostart-enabled=true Name=nvidia-fan-speed Name[en_US]=gpu1.desktop then you would change the gpu:0 value for each gpu gpu:1 gpu:2 etc If you would like to lower power caps on nvidia GPUs use sudo nvidia-smi -pl 135 135 is the desired power level in watts, so for my GTX1070 with a stock power cap of 151W 135 would be about a 10% reduction. This applies the same power cap for all GPUs and need to be set each time you boot. I havent figured out setting it up automatically yet. If you want to set individual power levels use sudo nvidia-smi -i 0 -pl 135 sudo nvidia-smi -i 1 -pl 150 The number represents the GPU id

Not sure if you ever got this going or not, but here are my notes from my 20.04 rig Install latest driver, reboot Enable coolbits sudo nvidia-xconfig --enable-all-gpus #use if running multi gpu sudo nvidia-xconfig -a --cool-bits 28 Reboot Then you can manually change fan speed and OC If you want to load your OC at boot do the following Create new file: sudo gedit /home/your user name here/.config/autostart/gpuoc_all.desktop In new window paste: [Desktop Entry] Type=Application Exec=nvidia-settings -a GPUFanControlState=1 -a GPUTargetFanSpeed=75 -a GPUGraphicsClockOffset[4]=100 -a GPUMemoryTransferRateOffset[4]=500 X-GNOME-Autostart-enabled=true Name=nvidia-fan-speed Name[en_US]=gpuoc_all.desktop Click Save, Reboot, Profit Note: you can enter any filename.desktop that you want, enter in your own fan speed, clock and mem settings. This config will OC all GPUs with the same settings. This config is for RTX GPUs, if you are using GTX GPUs change the offset parameters from [4] to [3] like so GPUGraphicsClockOffset[3]=100 -a GPUMemoryTransferRateOffset[3]=500 To edit the file afterwards gedit admin:///home/your user name here/.config/autostart/gpuoc_all.desktop If you want to use different OC and fan values for each GPU you would have to create a new file with the same info posted above for each GPU. Then you could name them GPU1.desktop GPU2.desktop etc

A little late to the party, but HighSpeed PC has tech benches and junk. I have 3 of them so far. Here is something that may suite you @BWG https://www.highspeedpc.com/category_s/1844.htm

This wont be updated 24/7 but I got it working anyways....http://franz.42web.io/summary.html Thanks for the writeup @BWG

In, but gimped for the time being due to some maintenance. Out for prizes. Just here to help

I found the highlights at redbull.com They still have Monte and Finland available to watch but I dont know how long they keep them up. Only 30min of coverage for each day, but better than nothing. I love WRC but im not paying over $100/yr to get the official livestream at wrc.com

I was able to catch the first 2 rounds of the WRC. Its been very limited coverage the last few years in the US, so it was nice to see those again, especially the Arctic rally which is always my favorite. Watching Oliver Solberg driving his first WRC stages was really fun, since I grew up cheering for his father and the Subaru team. Looking forward to the F1 season as well.

HFM.net is a great tool. I have used it for a long time to monitor multiple systems across my network with a mix of Ubuntu and Windows rigs. HFM is installed on my Windows rig and it reads the client from the Ubuntu rigs, because getting that installed on Ubuntu was a PITA. I haven't used the website option in years so looking forward to this.

@BWG Really nice to see you taking lead on this and getting the ball rolling. Although I tend to fold 24/7, summer is generally limited to just FaTs so I gave up on TCs a long time ago. Also my participation level tends to ebb and flow with whatever else is going in my life, so I might be super active for a week or a month and then disappear for 5 months....lol. I will dedicate my rigs to OCN until I hit 1 billion, after that I could switch my rigs to this forum and help move it up the ranks...

Congrats all and thanks again @ENTERPRISE for hosting a 5 day.....errr 4 day foldathon. @MinotaurtooIm usually 24/7 stable, but of course for the foldathon one system decides to f that up. Its an Ubuntu rig and I recently upgraded to 20.04 which doesnt play well with fahclient, so Im pretty sure I know what the issue is. @Bastiaan_NL the 17800 do seem to prefer smaller or maybe older GPUs. My 1070s dont seem to notice them at all with similar PPD to other WUs but my 2060s lose 10-15% vs other projects.

That is ubuntu, so he is using nvidia x server which should be installed when the drivers are installed and psensor which should also be preinstalled, but can be installed if needed. AMD definitely does something weird with their PCI lanes, when I added a second GPU to my B350 board it decided to make PCIE16_2 the primary GPU and PCIE_1 the secondary GPU, so my main GPU is limited to x4 lol. Then F@H set up GPU0(Main) as Slot 0, Bus1 and GPU1 as Slot 1, Bus10? Every intel rig I have its always bus1, bus2 etc

That was really fun! Reminds me of Foldathons in my past life. Nice job everyone, next time we need to get to 100mil PPD and or 900WUs in one day. Didnt win the 3060 lottery today, I was able to click on buy now at Best Buy, but could not add to cart. Oh well. Time to rig up a 3rd 1070 in my main folding rig.

I just woke up to a frozen system with a bunch of "error initializing CUDA" messages. Reset everything and it seems to be working....will dig deeper after work.

I need a riser cable for that but if I add my 3rd 1070 to that rig I will test it then Ouch, good to know

I compared x16 vs x4 on my 1070s recently. CPU 1700x, Mobo B350 PCIe 3.0 slots I used the same 75 Projects, but PPD still varies between WUs in the same project so.... x16 GPU Average 1,280,295 PPD x4 GPU Average 1,258,435 PPD 2% difference on GTX 1070s

Yeah playing with power levels is something I should really try. Im on air, because New England basement temps lol Im also pushing the CPU pretty hard with BOINC projects, so it could be starving F@H the CPU headroom it needs for the GPU.

Those are some healthy 1070s, Im on Ubuntu running +100 core and I am about 10% slower than you.

@BWG 3 2060s 2 1070s Normally I have the 2 1070s folding 24/7 and 2 2060s go to BOINC projects. The other 2060 is in my main rig and only gets used for foldathons I have another 1070 that I might add with an extension cable or sell depending on what happens on the 25th

@Bastiaan_NL The rigs are setup in my basement with an ambient of around 64F this time of year. Temps are rarely above 70c at 75%fan on all GPUs. Its hard to see in the pic but each rig has a single Silverstone AP181 pushing fresh air to the GPUs from the wall. I tried different positions and that provided the best temps. Without them temps jump another 4-8C.

Random hardware pic of the day. 2 Ubuntu rigs running BOINC and/or F@H No 30xx GPUs in sight......

There was an improvement in drivers last fall that boosted nvidia performance about 20-30% depending on GPU. I average 2.5mil on 1070s so 2.8 on your setup seems reasonable.

In! Thanks for the great event!

I won last month, you can give my prize to someone else.

Oh damn that's wonky. Thanks!

Mainly knowing how to run, start and stop programs without the user interface. Although folding can still be controlled from a Windows machine via HFM.net on the same network. How the dickens do I multiquote without copy pasting? I never used dummy adapters on my second GPU, but the main is still connected to a monitor through a KVM switch. I will PM the notes over after I read through them a bit.
