Folding Forum

I get full usage on core 0, 2 and 3 but Core 1 usage only ranges from 0 to 40%

This only started happening when I started doing a project on the CPU while GPU was idling.

Said CPU is an i5 4690K

By default the client configures systems with a usable GPU to reserve one CPU core for GPU folding. Otherwise the GPU folding process would interfere with CPU folding. You can change that if you are not using your GPU for folding using the Configure pane of FAHControl. Directions can be found in the Installation and Configuration guides.
