GTX 460 Not Folding At Full Power

Whatever the average TPF is for a GTX 460, I'm not getting that TPF. Say for example TPF is 2 minutes for a stock GTX 460 for the average WU, I can achieve that just fine when my core is clocked at 700Mhz, which is stock. If I overclock it to 830Mhz and resume a WU or get a new WU, my TPF increases to 5 min. HOWEVER, if I use Afterburner and configure it so it goes from 830Mhz 700Mhz, then back to 830Mhz, then my TPF for the current WU drops to 1 minute and 50 seconds. If I close F@H and resume the WU, then the whole process repeats itself

As for the overclock that I'm testing:

Core: 830Mhz
Shaders: 1660Mhz
Memory: 920Mhz in Afterburner which means 1840Mhz (QDR)
Core Voltage: 1050mV
Temperature: Max 62C. When I get that TPF of 5 min, 51C.

Now these are example numbers but I hope this explains the weird problem I'm getting. My SMP2 continues to fold just fine.

I'm on 270.61 drivers now. Didn't try the beta drivers.

Gotcha. So the overclock is not kept in memory of the application you are using. Like 10e mentionned, have you tried other apps?

[geokilla]

It is. It loads and applies my stock and overclock profiles just fine. It's just that it won't fold at full power like it should be.

Ok turns out it's going to 2D speeds. Dunno why I didn't see it earlier >.>

Looks like new WHQL drivers came out today, try updating/upgrading to those and hopefully that fixes your issues.

Download the latest drivers, but make sure you select the custom option and use the "perform clean install" option. Make sure the old drivers are completely removed. Then reinstall.

if it still happens try rivatuner...I think there is an option in there to disable the 2D clocks.

Go back to version 266.58. Latest WHQL drivers (have not tried version 275.33 yet) have issues when folding with GTX460's. It is the same problem I was having last week and the driver change solved it.

I found a way to force 3D mode. It's in the NVIDIA Driver settings. Should've stated that in my last post.

3D Settings -> Manage 3D Settings -> Global Settings Tab -> Power Management Mode -> Prefer Maximum Performance

[geokilla]

Ok nevermind. Forcing 3D mode doesn't work. Latest 275 drivers don't work either. Wth NVIDIA.

Try Rivatuner and disable 2D clocks
