Overclocking Amd radeon 6870

post #1 of 7
Thread Starter 
Hey Guys,

I just recently built my first computer and had a ton of fun.
I put a radeon 6870 gpu in it and have been messing around overclocking it via ccc.

Stock 915mhz Memory 1050mhz

Ive got it stable to 940mhz and 1100mhz How much further do you think it can go?

Also the temperature (according to furmark) is maxing at around 92c regardless of whether its OC or not.
Is this too high a terperature? Im a little worried.

Thanks a million!

Hey, Yeah so 92 is a bit high, but when you say according to furmark is that just your GPU temp or is it your shaders or memory. If there is only one value then more then likely its the GPU temp and memory tends to be about 7-10c higher then that.
On that note how long were you ruining furmark? also i would use some other things to test your gpu under load seeing as furmark is a bit unrealistic. also im sure you can change your fan speed with msi afterburner or trixx or even CCC. if CCC doesn't work try afterburner its pretty nice. Gl!

I wouldn't use CCC to overclock it anyway. Go download msi afterburner here and then set a custom fan curve. should be pretty self explanatory.

I ran furmark about 3 or 4 minutes. So far I like ccc plus its included with my driver. Unless I need to change voltage (which I dont plan to) ccc should be fine correct? Yes Im almost certian it was gpu temperature. I went and played Dayz for about 20 min and then quickly closed out and opened GPU-z. It showed temps around 70c, but they were dropping quickly so it could have been higher. Thanks for the quick reply.

with msi afterburner it allows for a custom fan curve as well as an in game overlay which you can configure to show you gpu temps, gpu clock speeds, core and mem clock, as well as fan speed, fan usage and gpu usage. very handy to make you just take a .4 second glance up or down depending on the corner you configure the overlay for, and make sure your card is still at a decent temp.

I just downloaded it and got it all OC, I'll try the overlay and see how the temps are. Thanks guys!

make sure you enable the custom fan curve, this helps out a lot for temps. default fan curve on amd cards sucks from my past experience.
