amd core 17 cpu usage

post #1 of 6
Thread Starter 
I could be wrong but didn't core17 used to not use very much cpu usage i see both my 7970s using a full core and on my other rig my 5870 is using 5-12% i remmberd befor they stayed around 2-5% tops. Im using the newest betas on my 7970s and 12.10 on the 5870 do i need older drivers to get less cpu usage ?

You are correct.

There was a time when the core_17 WU's, on AMD GPU's, were using less than one core, and i was able to BOINC on all my CPU cores while folding on my GPU. I'm not sure when this changed back to the GPU using a full core, but on the current beta drivers I am also seeing F@H using a full core on core_17 WU's.

What sort of ppd are you seeing on your 7970 now?

I just started foldng on the 7970 again. On the 13.10 betav2 drivers I was averaging 116k PPD on the 78xx WU's and 123k on the 8900 WU's.

The 7810 WU (first WU on latest beta drivers) that I am running right now is at 117k according to HFM.

Try 13.4, I've been using that on my folding rig with a 7970 and get 0-1% CPU usage.

ok so 13.4 dont have the cpu usage problem but would suck for gaming for me cause no frame pacing would work good for my single 5870 when i fold on it tho.
