I'm guessing that it only looks like it is the CPU usage percent that effecting your 2x275 GPU crunching and is more likely the GPU driver being *green* and throttling itself down into 2D mode.

I leave Precision open to keep both cores of my old GTX295 in 3D mode. Do not use SWAN_SYNC for 2XX series.

I'm pretty sure SWAN_SYNC is only ever going to use one core in total but I don' have 2x4XX to test that out for you.
Suspend WCG fpr a minute and see what Task Manager has to say about it?

If you are using WCG to manage your profiles they give you an option of a number of cores instead of a percent.

Are you on the XS team? Do you crunch under another name on GPUGrid?
Yes, on multiprocessor systems use up to 99% of processors. I have proved that none of my machines are throttling down. I do have EVGA precision set to load on startup for my windows machine. It is necessary for me to load it to get my 800Mhz core clock. I am not using WCG to manage my profiles, but I did try that. I did try using WCG to manage my profiles for a little while, but with the number of machines I have it would become inconvenient to manage different settings for each "group" of machines. Not to mention WCG only gives you the ability to create 3 profiles. I am on the XS team and I only crunch under the one profile.

I've since taken the linux machine out of crunching completely. The DFI Lanparty Jr X58-T3H6 has been nothing but problems since the day I bought it. I have called their customer service and gotten worthless responses. The board has been unreliable as could be since the day I started using it. I've changed RAM, CPU, power supply, everything. The computer doesn't always POST, doesn't always shutdown when I try to shutdown from the OS, doesn't always reboot. Today I flashed the BIOS with the latest version hoping to fix the unreliability issues with turning on and off the computer. Now linux won't boot and I don't know where to begin to fix it. I've had it with DFI and the motherboard. If it weren't -25 outside it would be in pieces right now thanks to my baseball bat.

As it stands right now I have no linux cruncher. I have appeared to fix my PPD issues with WCG and GPUGRID running simultaneously by forcing the GPUGRID process to run at higher priority.

My HTPC machine with Windows 7 x64 is currently making about 35kPPD/day crunching both WCG and GPUGRID using priority64 by eFMer set to force all threads with acemd2 to a priority of "normal". Of course, I have also changed my GPU settings to use the computer only when idle for 2 minutes so it doesn't affect my gaming. This has killed my PPD for my SR-2 rig which i'm okay with.

Honestly, I'm running out of patience with this crunching thing. It's not very easy for someone to setup their machine to crunch without knowing a bunch of little secrets like SWAN_SYNC, forcing higher priorities, etc. Don't forget you gotta make sure you have the right version of the drivers installed. One thread on GPUGRID was trying to tell people to use a driver version from 197.xx. Sorry, I'm a little more than pissed that one thread says "always update your drivers" while another says "keep the old drivers". I'm about to say this .
