The CPU that's processing one of the FAHCore_a* tasks -- which if one thread per GPU is left idle, is whichever one is NOT processing other things.
I meant what make/model of cpu is he using
If you mean me by ‘he’ then it is a Pentium G4400, a dual core CPU AT 3.3GHz.

Re: GPU CPU bound?

Cranking up the base clock on the GPU with 100MHz already seems to deliver an extra 5%. Maybe I will try some more serious overclocking, as mentioned here earlier, and see what comes out of that. This little extra already proves though that the CPU is indeed not a bottleneck.

Re: GPU CPU bound?

Linux might give you 10% boost over windows. Serious overclocking and selective reporting of PPD also come into play, so take the spreadsheet with a grain of salt! I also use G4400 CPUs - driving pairs of 1080 and 1080 ti - A single 1070 won't be bottlenecked. Running Linux may be worth a try. Any ...

Re: GPU CPU bound?

The long term average for a 1070 is around 600k, I've just checked mine and its currently showing 512k PPD on a 9839WU, when I came in this afternoon it was showing 665k on a different project, that's on a PCIe 3.0 x16 slot running heavily overclocked on a 4c/8t cpu at a much lower clockspeed than ...

GPU CPU bound?

Hi, I am runnng a GTX1070 on a low end MSI H110 mobo with a Pentium G4400 and Windows 10, running only a single GPU slot for a couple of months now. I never get above 600k PPD , even if I increase the clockspeed of the GPU. The CPU is running at 53% on FacCore_21, probably meaning that one core is f...
