GTX 460 freeze followed by reduced clocks

[wotevajjjj]

Hey guys,

A weird thing just happened to me, while playing some crysis 2 my 460 froze up for about 5 seconds, and then ran at 405mhz.

No mather what I did with afterburner, I couldn't get them back to 900mhz.

My clock is completly stable on both gpu and cpu (OCCT tested for 3hours).

Now I would just assume this is a driver problem, but it only just started happening.

any ideas ?

Not exactly gaming,but i had the same downclock problems when folding,after i installed new driver.What i did was uninstalled all nvidia drivers and nvidia related programs.

Installed new driver,and it solved the problem.Havent had any trouble since.

Are your temps okay?

Temps go to 73° max so those arent the promblem, going to reinstall drivers now

I've had issues with the latest driver and the beta before that, where at the desktop using the aero effect the driver was crashing, the fan wouldn't start up with after burner... luckily the card has a failsafe thing so when it goes past 90 regardless of setting it cranks the fan...

I recently reinstalled windows and just let it install it's own 460 drivers, sure enough haven't had any issues. I believe it's a release or two ago, which I had no issues with what so ever

Hi,

I've seen similar behviour. In my experience it was due to a slightly unstable OC. Card was ok 99% of the time but, occasionally, it would crash and the clocks would drop to some fail safe level (really low, but higher than idle) Changing things in afterburner would then not actually change the clocks until a reboot.

May I suggest that your 460 is slightly unstable at the speed you're running at for some reason. You might want to try lowering the clocks slightly or simply giving the GPU a slight voltage boost using Afterburner. Doing this on mine saw me never get the issue again.

One thing I will say though... Older NV drivers you HAD to reboot, newer drivers would let you OC the card again after a minute or so. Seems like the card (drivers) reduced the clock for a certain amount of time to protect things.

Crysis 2 does work a GPU particularly hard with the DX11 patch I've found.

I really think this is a slight GPU OC instability, as your symptoms describe exactly how the drivers respond when a problem is detected but caught before the system BSODs. My system too was fine during numerous stress test scenarios but, every now and again, I'd experience this until I refined my OC.

Best of luck,

Scoob.
