How can i overclock my GTS 450 higher?

post #1 of 3
Thread Starter 
My current clocks are 1000/2345 through MSI afterburner.
The Memory slider is maxed and the core slider still has room, however i can't apply anything past 1000mhz. it will "apply" in the slider but the monitoring part still says 1000mhz. also checked with gpuz and it says 1000. How can i go higher?

Temps are 67c through furmark and its all stable.

This limit is set by NVIDIA.
Before you do this, you should know that bypassing this limit its very very risky.

1) Open the folder where afterburner is installed.
2) Locate the cfg file names 'MSIAfterburner', open with notepad.
3) After "UnofficialOverclockingEULA" add this text:
I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
Set UnofficialOverclockingMode to 1

While kenpachiroks method may work (i never tested it) i use a modded BIOS on my 450's to top them at 1255 MHz on the core. I've never used that method to OC any Nvidia card, i prefer modded BIOSes, that way i don't have to redo that setting if i reformat or change the card to another computer biggrin.gif

Right now my 450 is running @ 925/2000 as it's back to stock cooling, but when it was underwater i had it @ 1100/2100 MHz. The driver i used was the 290.53 beta, i'm not sure if the newer drivers have any new limitation though.

I'm wondering what cooling you have on your GTS 450 though.
