Folding with i5 2500k and Radeon HD 6950 PPD Help

post #1 of 24
Thread Starter 
When I run both SMP and GPU slots at the same time, my SMP PPD plummets from ~14k PPD to 8000 and under (sometimes I get 0 PPD!).

When I run them alone, I get ~14k PPD for SMP. My 6950 gets ~9000 PPD whether I'm folding just on that or in combination with SMP. I have read about AMD GPUs not being that great for folding and that they need a CPU core to themselves, so I limited SMP to 3 cores so that my GPU can use the other core.

So basically when I'm folding using both SMP and GPU I am getting huge losses in PPD and it seems to be best to just forget GPU folding and fold SMP alone. Is there something I can do to make them get along to maximize my PPD?

I'd say you're right in your assumption that the 2500K will net you more PPD. OC that baby to 4.5 GHz+ and you'll see around 20K PPD. thumb.gif

Unfortunately, until folding is better optimized for AMD GPUs, that's gonna be how it is. redface.gif

I guess things haven't changed much on the AMD front then.

I'm already at 4.5 GHz. Most of my WUs have been finishing giving me around 14k PPD. Is there anything I should be optimizing or configuring to get 20k PPD?

Hmm.. Other than configuring it for Linux, there's not much else you can do... I'm not sure why you're getting 14K though. Even when folding SMP in Windows 7, I never got lower than 17K at 4.5 GHz. Did you enable bigadv? I think that makes a difference.

Can you really fold bigadv with 2500K?

No I know you can't anymore (at least as far as I know), but I was under the impression that configuring your client for bigadv gave you WUs that gave better points, not just the bigadv and bigbigadv WUs.

Feel free to disprove this. biggrin.gif

Yeah I thought it couldn't be done (at least without virtual machines running or something of the sort to fool the client into thinking there was 8 CPU threads).

No I didn't do it but I guess I can give it a shot.

Will web browsing and listening to music hurt my PPD by a lot? Is that maybe why I'm getting ~14k PPD instead of ~20k PPD on my 2500k @ 4.5 GHz?

If that's all you're doing, then no. Playing games will though, especially CPU intensive games.

In my case web browsing does hurt my ppd for SMT folding. Though it is not a huge decrease.
