Folding power for GPU

Post by sk69 »

I see that by changing the folding power between light, medium, full, the number of CPU threads/core used change. But I do not see anything change in the GPU on the user interface. Does that slider affect the GPU utilization too?

The slider doesn't change the amount of GPU usage. On Light, it will enable GPU when the system is idle. On Medium/Full, it will continue to use the GPU (IIRC).

Really GPU's are not subtle beasts they are on or off unlike the CPU. You can download a 3rd party app msi afterburner is the one I use to limit the power and temps or if you are up for it overclocking. I have to admit the new cores and RTX cards have moved me from a cautious overclocker to a cautious power limiter.

Almost, @PantherX: Here is the exact impact of the "Folding Power" - Slider. If that information is up to date, that is.

I think that was written when four core cpus reigned … Fairly sure it is Full is all CPU cores … Medium is all less one CPU cores … Light is half CPU cores … GPU is on for Full and Medium but paused for Light.

Actually, that description was modified by someone from an older, more detailed page who assumed information not supported by the client code. The settings always have been up to version 7.5.1 of Full uses all available CPU threads, Medium uses one less, and Light uses half.

One of the versions before 7.5 separated out the "On Idle" from the slider position, that was the reason behind editing the page from the older version.

As far as I know, 7.6 does not change this part of the code for the client.
