GTS 450 volt tweaked overclock
Hey community!


The other day I started to play around with the voltages on the GeForce GTS 450 to get some more power out of it.

Right now I have the settings on(According to MSI Afterburner):

Voltage: 1100v
Core Clock: 950mhz
Shader Clock: 1900mhz
Memory Clock: 2260mhz

So I was wondering, does anyone think it would go any higher than that? Right now, if I have the core turned up any higher, the driver crashes after a minute or two and if I have the memory any higher, it artifacts on some games (Crysis, FarCry 2, Red Faction: Guerrilla). I was really asking if, if I turn the voltage up higher.. Do you think I could get higher, stable, clock speeds?

Thanks everyone!

Why dont you try! The max voltage you can use is 1.138 right? Apparently that's safe for the silicone. All you can do is try, just watch those temperatures; however i have no idea how hot those things run.

If, with extra voltage you see now benefits, try increasing the fan speed to allow the card to run a little cooler, that might net some gains also.

Hey thanks for the reply! I'm going to try and put some more volts in it and I hope I can get the core up to 1000mhz :D The problem that I face though is that I think it's the shader clock that wont go any further, and the core and shader are linked. And it wont let me un-link them which sucks. The memory and shader sliders are almost completely at the end but the core is barely half way. Do you know how to un-link the shader and core?

emmm...
1.163V, core/SP runs at 990MHz/1980MHz and passed 3dmark Vantage test.

I found there is a vdrop on video card, like cpu
ex.
I set gtx480's voltage to VID 1.075V, but gtx480's sensor reports the voltage is 1.054V (according to GPU-Z)...
