voltage for the GTS 450

post #1 of 7
Thread Starter 
what's the max voltage i can apply to a GTS 450 card? default is 1.025 and i was able to reach a stable 920Mhz core clock with it, going to a stable 980Mhz core clock requires 1.125 my GPU reaches 82C fan speed @ 75% under stress test,

is it worth this voltage increase for a 60Mhz/120Mhz increase in core/shader performance? more importantly, is 1.125 safe for my card?

If you could keep it cool enough, you could go all the way to 1.212v which is obtained through flashing your bios.

So, its more of a question of temperature. Some of the bigger cards, like the 470 and 480 were a little more sensative to the voltage.

The max voltage is indeed 1.212v. I've safely increased my 450's to 1070 MHz on the core with that much voltage (via a flashed BIOS) and under water, and they're doing fine.

Just keep temps under 90c under true usage though. I do not use Furmark or the like, i have gotten lots of cases where an OC is Furmark stable but it crashes on 3dMark or Heaven. I'd use both of those as stress testing, and the Crysis benchmark as well. There are some other games which incluse a built-in benchmarking tool, you could also try them, or just run the games you wanna play. Nothing beats real usage for stress testing.

@ 1.125v. the fan is already loud @ 75% with a core temp of 83C, but i could reach a stable 980Mhz on the core or a stable 960Mhz with 1.10v ,

however the memory won't go past 3840Mhz no matter what but i guess the voltage raise only effect the core/shader

First of all, could you stop increasing the font size? It looks rude.

The RAM may bot be as good OCer, but also you might need more volts to run though it. If you only got one voltage slider, it controls everything, not just core/shader speeds. My own GTS 450 was able to reach these clocks underwater and with 1.2v

I could get to to 1070 MHz core speed with 1.212v, but i had to lower the VRAM speed down to 1050 MHz.

I agree, especially with how you don't seem to be happy with your temps/noise. Just pick a cheap aftermarket cooling kit (like the Accelero L2) and some good TIM (some MX2/MX4 will do the trick) and watch the temps and noise go down.

no luck mate, the memory won't budge over 970 even with a 1.175v (the max Gigabyte OC Guru II allows) and the temps are already out of control at that voltage tongue.gif
