GTX 4601GB Over-clocking Impossible?

post #1 of 11
Thread Starter 
Every time I try to over clock my model the games I run either end of flashing and setting the GPU settings back to default settings or it crashes games. My stock model is set to 763Mhz it is a EVGA model, I tried setting it to 863 Mhz and over clocking the memory from 1900 to 2100 and still not working right.

Any suggestions? Is there some cooling settings I need to change or something?

Specs:
OS: Windows 7 64 Bit Ultimate
CPU: AMD Phenom 2 x4 3.2 Ghz BE ( I should note I still cannot over clock this properly)
RAM: 4GB of DDR3 9-9-9-24-33 1T
GPU: EVGA GeForce 460 SC 1GB GDDR5 (Latest Beta Drivers)
Motherboard: MSI Nf750 g55
Soundcard: SB X-Fi Titanium
Screen: 1680x1050
PSU: 630 W

You need to increase the voltage output to the GPU.

Overclock your GPU core first, dont touch memory till you are satisfied with core.

And a memory overclock seems a bit high, Maybe you should just try for 2000 mhz.

I tried MSI Afterburner and it says my voltage is "1025" with a maximum of "1087" what should I set that too?

you tried increasing the core by 100 mhz ? you are supposed to increase it only 20 maybe 25 mhz then test and if its working increase more and repeat untill you find the stable one.
BTW most 460's are not going to work on 863.You should expect maximum 850 or 825

880 on "1087"
and if you want to stay on lower temp make it like me 840 on 1025 (it's 100% stable)

Great I will try those two out, but btw what about over clocking my Phenom CPU? Do I need to overvolt that too?

Just got max GPU temp @ 85 C while running Furmark @ 1680x1050 on full-screen while over clocking to 840.

Just tried 880 and it crashed the graphics driver.

what voltage did you bump it up to for 880?

it really sounds like you don't know how to overclock.
you have to take baby steps to get where you want.

you are rushing, and this is how hardware gets destroyed.
