Overclocking GTX 460 1gb problem

Hurlbag · 23 Apr 2011 at 02:14

Hey, so currently my GTX 460 is stable at 825mhz core (linked shader) and 2100 mhz memory - using stock voltage. (MSI afterburner)

I'm trying to push it further up to 900mhz core, it's not stable on stock voltage so I tried 1.087v, the max it will go and yet display driver still crashes with core at 900?

What gives? if it can run 825mhz on stock but not an extra 75mhz on max voltage in Afterburner?

GPU-Z reads the voltage increase, but i'm wondering if MSI afterburner actually changed the voltage value or not, and just shows a bogus 'altered' value? Is there anyway to confirm what it really is?

Thanks for reading, any help appreciated.

75mhz isn't a small amount to add to 825mhz. It's very possible that your card just isn't one of the awesome ones that go a lot higher.

If GPU-Z is questionable, try something like CPUID HardwareMonitor, it may give a more accurate voltage reading. Must say though, just chucking max volts through it is generally not the best way to check these things.

My card would not clock that high either. Why dont you flash it. You will be able to clock higher then

I did just this, not being able to push it further was driving me insane.
My voltage is now at 1.125 and appears to be stable @ 900

Temps have barely increased, happy overclock! was so quick and simple, I found out you can actually flash it while in Windows 7 by running cmd.exe as administrator.

A question I have about the memory clock, if i'm only using one monitor (1920x1024) will pushing it over 2000mhz churn out anymore more performance? or would that only be necessary if I had dual monitors or something?

it will still help but its not going to be mega.

i flashed my card to slow the fans down at idle thought it was to loud.

also did mine in windows

Mine runs pretty stably in games at 1.087 volts at 925/2000 clocks. Furmark doesn't get along with it so well, though.

It's fine at 1.087 running 900/2050 but not 900/2100. The latter gets through kombustor fine but Heaven benchmark crashes it.
