Bios, Voltage and overclock question for GTX 470.

post #1 of 5
Thread Starter 
Hello! I've just changed the cooling for my Asus GTX470 with Gelid Icy Vision Rev.2 air cooler and now it runs at about 65-70*C while overclocked at full load while playing games at 800/1600/1674 at 1.075 voltage with MSI afterburner (force constant voltage on checked) and with stock bios.
I want to ask if i modify my bios to let higher voltage since my cooling can handle it, will i be able to achieve greater clocks and will it damage/shorten life of my GPU ?

Yes, you will be able to run higher clocks.
No, it won't damage your card. Both the 470 and 480 are very solid cards that can handle ALOT of extra voltage.

All you need to do is keep the temperatures under control, because they will skyrocket once you go passed 1.10v. I think your Gelid cooler will be able to handle voltages till around 1.13-1.15v, depending on the core clocks you'll be using.

Ok so far so good. Will my CPU handle the card well if i don't overclock the CPU and OC the card to about 900Core clock ? That's cuz i don't have a good cooler on the CPU and i'm stuck at 2.8ghz per core.

Ok i've updated my bios and i can set new voltages up to 1.2xx .
Now i have another problem. No matter how high i set the voltage and i've tried up to 1.150 i am unable to get stable clock over 810 core while playing games. Best stable clock so far is 800 core no clocked memory with 1.112 voltage and the game is sometimes but rarely showing artefacts. Any suggestion on how to get a higher stable clock ? Core temp while playing at my best clock goes up to 73*C.

You've probably hit the limit of your particular card. Just be happy with 800mhz since 800-850mhz is going to be the max for most 470's. I wouldn't go over 1.15V personally.
