Light Power for CPU and Medium for GPU?

[trypt]

Hi all, hope I'm posting in the right forum- I'm new to F@H and having an issue getting my folding setup how I want it.

CPU: i5-8600k
GPU: RTX 2060

When I first started I left the power slider at medium, so CPU & GPU are both folding. Except my CPU temp went up to 97 C which is really higher than I'm comfortable with.

So I changed power slider to Light, but that set the GPU to only run when Idle. I'd rather have the GPU folding while I'm working, but I can't figure out how to force it while leaving the power slider at Light.

Any tips? I tried going to Control -> Configure -> Slots -> double click gpu, and removed the "expert only" slot option that said idle=false, but no luck.

Welcome to the F@H Forum trypt,

Please note that the CPU temperature would indicate that you may have insufficient cooling for your system... when you can, investigate into that.

Here's what you need to do:

1) In Web Control, set it to Full and while working.
2) Open up Advanced Control (AKA FAHControl) which should be present in the taskbar's notification tray. It looks like a molecule.
3) Click on Configure
4) Click on Slots tab
5) Click on CPU Slot
6) Click on Edit
7) In the CPU Value, replace the value with 3
8) Click OK
9) Click Save

Thus, you will end up with the GPU folding at 100% and the CPU folding at 50% while you use your system

Thanks for the quick reply! I was surprised by the high CPU temp as I have a pretty good aftermarket heatsink/fan (Noctua NH-U9S), and had never seen temps that high even when running cinebench.

I think I found the culprit though, I had all my fan profiles set in bios to 'standard' - switched to performance, and set chassis fans to trigger on CPU temp - now I'm running F@H on medium power and CPU is sitting at 75 C so far.

Good to know how to adjust the CPU use and force GPU too!

Folding is more stressful than Cinebench. Generally speaking, folding is very stressful compared to various other benchmarks. One of the reasons is folding uses AVX instructions which many popular benchmarks don't use or fully use it.

Hey PantherX, I'm trying to limit the number of CPU threads on my laptop and this doesn't seem to do anything? I have a 4C/8T process, I've set CPU threads to 2, and all 8 threads are still being used. This is on any power setting. I've tried restarting the F@H client, and waiting for the current WU to complete, still not noticing any change in CPU/thread utilization as I change the cpu slot thread count?

You may want to check that the change to the CPU slot configuration actually saved - because it should take effect immediately it has saved … If still not working could you post your log making sure to include the top 100 lines of so with the system configuration and the last part that should include the change to threads=2 … for help with posting logs see viewtopic.php?f=61&t=26036

Aside from lowering cores, You could also disable hyperthreading in the BIOS. It helps in reducing CPU temperatures. You'll probably be limited to 3 or 4 cores on CPU though.

Just curious, from the Clients help we can get:

Code: Select all

gpu-usage <integer=100>
GPU usage as a percent from 10-100

Shouldnt that be the correct way to limit GPU usage?

For the GPU version of the limit, that applied to an older GPU folding core that is no longer in use. As far as I know it will not have any effect on the current cores.

Whether it works as advertised on GPUs, is questionable, but it's not recommended since it has to turn the GPU on and off intermittently. That generally is go be avoided since thermal stresses are harder on a GPU than continuous temperatures.

As far as I know it will not have any effect on the current cores.

I tried Values "75" and "25" and cant see any difference on my GTX 1660 Super.

Overall System power consumption stays the same,
GPU ussage stays the same,
Estimated PPD stays the same.
