No additional parameters are assigned to the CPU client.

Hmmm... that's strange. I'm new to Folding and I had to RMA my GTX 770 on Friday, so now I'm running on my old GTX 570 (temporarily) and am currently getting 48,192 PPD and I've got the same settings as you with the GPU.

Your 6950 isn't very efficiently utilized by any Fah-core, the core_17 (which you are running) is better than the _16 though. I saw a peak of about 17k PPD on my 6970 while it was folding stock, P8900.

The CPU is running with just three cores and in Windows and quite a modest OC. Should maybe be able squeak out a bit more PPD. I'd put the same flag/option on the CPU as well. I usually get a bit better units that way.


However, as been said time and time again over the forums, FAHControl is outright terrible at giving a usable PPD estimation. It swings widely from high to low. Install HFM and get a much better idea of what you are gonna get. I have a unit folding right now which actually have an avg. TPF of 12:58/356k PPD, FAHControl says it's 16:10/283k PPD...

There's a big difference between a 570 and 6950 in FAH. However, i suggest you also try HFM and see what it says for PPD. There are also several ways which it can calculate PPD/bonus, I use PPD calculation based of effective rate and bonus from download time. A 570 is likely to get 35-40k if the OC is right.
