	Dear all, It has been a while since I haven't posted. I've decided to crunch again on GPUGrid with my 2*GTX570 on my Ubuntu 64b. However, after 1 days and several hours I have only crunch 4% of the 2 WUs... Doesn't since right... Any idea why? For info, no problem with others projects (Like Primegrid) and I did not add the SLI bridge between the graphic cards + I only have 1 monitor plugged. Thanks for your help !! ____________ MyUneo, the Cupid of Services

	What are your clock speeds? Graphics clock: ? Memory clock: ? Processor clock: ? Also, what is your fan speed?

	Everything from stock. Temps are quite low (like 65 degrees with only fan at 40%), with primegrid, much higher. ____________ MyUneo, the Cupid of Services

	Hi. Do you have two cores available for gpugrid.net tasks? If not, free up the two cores.

	I am presently running a Ubuntu 11.04 64bit OS on an i7-2600K, with a GTX260-216. Actually just put it in to test following another post. I had to go to NVidia control panel and set it to run at maximum performance, and free up a CPU thread. I recommend you do both of these things, and I would also suggest you set up a cc_config.xml file to report tasks immediately, and keep a reasonably low cache (0.25 or less).

I'll try to free 2 cores them and to check the Nvidia panel. I'll you know. ____________ MyUneo, the Cupid of Services

	Everything from stock. Temps are quite low (like 65 degrees with only fan at 40%), with primegrid, much higher. I have a GTX 570 too. If it's running that cool with only 40% fan speed then probably your GPU is running at low speed. The "stock speed" actually gives you 3 speed steps. I am quite sure your GPUs are not jumping up to the highest speed when the GPUgrid task starts. Open the nvidia-settings application via your application launcher or just enter "nvidia-settings" in a terminal. On the Power Mizer page you'll see the clock speeds your GPUs are running at. When the GPUgrid app is running the clock speeds should be: Graphics Clock: 742 Memory Clock: 1900 Processor Clock: 1484 If the speeds are lower then that is why your tasks run so slow. When you get the clock speeds up you'll want to increase the fan speed too. My 570 does not automatically increase the fan speed when the temperature rises. I had to "manually" force it to higher speed. I posted directions on how to do that here.
