GTX 560 stays at 3D clock speeds.

Hi all, I recently bought my new GPU - a GTX 560, I'm loving it, I can play most new games at over 30 fps on the highest settings.
However I have one problem, and this problem makes my idle temperature higher than my load temperature. I KNOW This cannot be good for the life of my GPU.

It will NOT go back to 2D clock and memory speeds. It says at 3D at ALL times, even if it's when I've just booted up my PC.

Here is my system setup:

- NVIDIA GTX 560 by Gainward
- Gigabyte GA-G31M-ES2L motherboard with G31 Chipset
- 4GB G-Skill DDR2 Ram
- Intel Pentium "Wolfdale" E6500 @ 3.5 GHZ running at default voltage
- Corsair VX-450 watt PSU
- 2 Monitor set up, 1 via VGA, 1 via DVI
- 1 EcoGreen SATA 2TB HDD

I heard that using a multi monitor setup makes the 3D clocks "stick", if so, does anyone know how to fix this?

P.S I plan on overclocking my GPU to maybe 971 / 1176. I believe I can do this despite having a 450 watt PSU.
Could I use MSI Afterburner to set a profile to force 2D clock speeds and the Overclocked 3D Speeds during 3D games?

Thank you!

You could try playing with the settings in the NV control panel but I think the 3D clocks with two monitors thing is more of a feature than a problem.

Whit is your idle temp? Do you have the 1 GB or the 2 GB version?
You say you don't want the temp to affect the life of your GPU and you want to overclock it.....18%. I can guarantee you that will raise both the idle temp and working temp.
You can't have it both ways!!!

Hi, What I meant was I want to have an idle profile and a load profile, I don't want a permanent overclock, I only want the overclock for 3D games.

I breadboarded the PC earlier - 35 degrees with one monitor on idle, around 40-45 with two on idle.

And I have the 1GB version.

Running two monitors with the card at 2D clocks is not possible IIRC.

Also, I wouldn't worry about temps, 45C is nothing for a Graphics card. The life starts getting shorter at 90C.

I tried finding a solution to this issue multiple times with my various video cards and never came up with anything. So I am now using both my 560 Ti and the Intel HD3000 IGP so the 560 can run @ 51/101/125 when idling.
