You shouldnt get more than 340 mhash on a 5970 core @ 725 MHz, even with perfect ram speeds and miner/kernel options. If you're spiking 350-370, definately something awry going on there. Is your GPU activity maintaining 99+%? Doing nothing on the computer running on the miner? I'm running 5830, 5870, 5870, 5970, and 5970 and I get sudden dips of GPU activity (40-70%) if I do ANYTHING on it, and it kind of cascades between the 7 GPU's for about 30 seconds before stabilizing and getting back to 99.5+%

My GPU's maintain about 60-75% activity. And yes, its a dedicated mining-server at the momemt, so I'm not doing anything else on it.
Tried only running one core again and then the activity goes up to around 96-98%. Strange..

What driver/SDK? Back with the old 100% bug if I ran both my cards on the same CPU, their hash rates would suffer.

As I wrote in the main post, 11.10 and SDK 2.1. When it comes to the CPU it maintains about a 50% load.

You shouldnt even get that much load either. I get 1% CPU on a 7 GPU rig, single core 2GHz. I'm going to bet you have a dual core CPU. You still have CPU bug. 11.12 and 12.1 don't exhibit the CPU bug with 2.1 SDK. Unfortunately, I tried 2.5 SDK a little while back on 11.12 and I had CPU bug. Will take some futzing around to get a 2.5 SDK combo working..

Then I'm gonna give 11.12 and/or 12.1 with SDK 2.1 a try. Thanks for the tip. And yes, I do have in fact have a dual core CPU(C2D).
