On this mashine Im crunching almost 24/7. Its W7 4GRAM GTX 460 (last drivers - I red about probs just now). I overclock it with MSI afterburner slightly just now, but also no difference... Thanx for any info.
On my second mashine Im crunching with the GTX 470 and the performance is 4 times higher, RAC litle bit over 100K.

PhysX can interfere w/ crunching?

you only got 50-60% GPU-load - why?

set boinc to use only 50% of CPU's

you got physix installed - you will not need it here, but it may interfere with crunching.

I decided to stop Rosetta processing for a long time, funds are tiny an energy effort is gigantic for that amount of credit.

Strange thing, i incresed my gpu usage by overclocking the pcie frequency,

getting 5-10%, but results at this time are not save.

You can try if u will set to 105 Mhz on PCIe frequency, by your own risk.

using two GTX 460 gpus on same board.

Your OC (+27%) is probably a bit too high and is causing the failures,

Your fan speed is asking for trouble, 40% and might also explain why you are getting failures - While 71degC isn't bad, ~60deg should be readily possible for that card, especially if 40% fan speed => 71degC.

If your CPU tasks consume 100% of the CPU processing capability that leaves nothing for the GPU. In reality the GPU would have to contend for CPU usage when required. Obviously if the GPU has to wait for the CPU to become free in order to process something on the CPU (even if it takes <1ms) before returning to GPU processing (repeat many times over tens of thousands of seconds) then GPU performance will suffer. To what extent depends on the specific task being run; some GPUGrid tasks such as Ignasi's presently have to do more processing on the CPU, while other tasks such as Paola's (AFAIK) use less CPU resources.

The FAQ's cover most of this.

Fan speed is set automatically. What I can do here (besides set it manually)?

ok, absolutly no zero advantage by overclocking pcie bus frequency, what a mistake.

i change clockings immediatly.

your athlon x2 is a pretty slow thing.

OK, I understand it may be the W7 thing. I have 0.44 CPUs + 1.00 NVIDIA GPUs usage not depending on swan_sync=0 or stopping the rosetta. But strange thing is, my other machine with XP has almost the same usage (0.46 CPUs + 1.00 NVIDIA GPUs) and GPU usage on some 68%! Im using latest BOINC manager: 6.12.34, ndvidia drivers on W7 machine 295.73 (and 285.58 on W XP)
