GTX 460 and 2D / 3D clocks

post #1 of 5
Thread Starter 
When checking my computer remotely, through this link, I sometimes notice that GPU 1 has gone down to about 4k PPD instead of the usual 9-10k. From what I understand, this is due to the card switching to 2D performance mode. Is there any way to prevent this from happening? Obviously, I'm not using the computer, and seems to be quite random. Some days it never goes to 2D, and others, it is like that for quite some time.

The only difference between my GPUs is that GPU 1 has a DVI cable to my monitor and GPU 2 has nothing, or at times, an HMDI cord to my TV.

Another one of these? I get no rep and answer these twice a day. :l

Nvidia really needs to tell people this:

Go to the nvidia control panel. Go to manage 3d settings. Choose global settings. Scroll down until you find something labeled power management mode. Change from adaptive to prefer maximum performance. Apply. Yes. Close control panel. ???. Profit.

Side note: If you've OC'd these at all and it's unstable then when the card crashes it will drop to the lowest clocks set by the BIOS on the GPU board.

EDIT: So this solved it? Glad to help. Really wish nvidia would mention this though. There's a lot of threads about the drivers not detecting GPU usage properly.

Thanks!

Exactly what I was looking for. I've known the problem, as it is mentioned quite frequently, but I've never seen an actual "fix."

We recommend that often, but the issue still arises from time to time.

stu., the best method is to make an OC profile in RivaTuner, and apply that to your GPU. It should keep it at 3D clocks.
