Re: R9 280x rig 100% cpu load, low PPD (80k vs 115k)

There are many, many reports where folks were running both GPU and CPU (SMP) folding. We're certain that if all of your CPU threads are devoted to Folding and/or other CPU-intensive processing plus the GPU driver needed CPU processing (over-committed), this will adversely affect the CPU/SMP folding...

Re: R9 280x rig 100% cpu load, low PPD (80k vs 115k)

For those of you who have been helping :)

Forced bios to select pci-e 3.0 (gpu-z still sees it as 1.1 or 2.0 depending on load) and updated drivers to 14.4

The rig in question is now at 127 to 132ppd per card!

Still going to test for bottleneck on CPU next.

Thanks for everyone's help!!!!

Re: R9 280x rig 100% cpu load, low PPD (80k vs 115k)

Thanks PantherX I am using driver version 13.12 right now. I think I will try out 14.4. I am going to try the troubleshooting method you suggested. After reading the post by nookiebandit, Pending the outcome of troubleshooting a suspected cpu bottleneck, I may also end up upgrading this computer to ...

Re: R9 280x rig 100% cpu load, low PPD (80k vs 115k)

Thanks!

There is a big difference between excitement and knowledge!

I am excited to be folding, and probably obsessed with efficiency.

I appreciate all the help and info

Re: R9 280x rig 100% cpu load, low PPD (80k vs 115k)

I just calculated my PPD using the calculator. It ended up being around 100k on the several different instances I checked on 2 of the cards. I then noticed that one of the cards had started new a project and had low ppd estimate. The other 3 are cruising along at 100k ppd. CPU still 100% But the GPU...

Re: R9 280x rig 100% cpu load, low PPD (80k vs 115k)

Thanks for the quick reply. I wish my original was more thorough. But alas, the back button on my mouse betrays me. I hate to just write the problem off as throughput on x1 as 3 of my other rigs do not appear to be suffering. Every card I have in folding rigs are using X1 slots... My other R9 280x r...
