Is GPU Overclocking really worth it? (5870)

post #1 of 10
Thread Starter 
I've been messing around with my single Radeon 5870 card. (First overclock attempt, I'm still a noob )

Stock settings are
850 Mhz GPU
1200 Mhz Memory


I've bumped it up to 940/1300 @ 1.175v (Stock Volts) which handled about 10 minutes of FurMark 1.9.1 at 69 degrees keep in mind I have a stock fan and only saw about a 1-2 frame increase.

If so, how much farther would you go? I already know the basic answer - "Until it starts to artifact" but im still a noob keep in mind. I just need advice. Ideal Temps to watch for, GPU vs Memory in terms of heat (I'm OC'ing for Battlefield 3 when it comes out which is GPU Demanding.)

The best way to benchmark it is by using Fraps while in a game and compare the differences during actual gameplay. I think you have a typo, the stock volts are 1.075V's, I believe.

1000 core is as high as id go on air

Overclocking amd card's dont achieve much , nvidia cards are the best to overclock ..

it will smoothen out the gameplay though , does for me anyways .

Ah, I knew it was something like that. I just knew it wasn't 1.75V's. Lol

Anecdotal: MSI TFIIIs in CF unlocked at stock r6950 clocks vs 1.25v/950core/1450mem yielded a 14% improvement on my Furmark 720p bench rating. I would say the most significant thing you can do to improve framerate would be overclocking your gpu short of buying a second video card (assuming your CPU isn't a bottleneck). Heat is the only issue other than artificating when OCing. Your 69C temp after 10 minutes isn't bad but it isn't very good either. Any way you could get better airflow in your case?

Definitely worth it, try 3dmark or a rePeatable benchmark. You should see a increase unless your cPu bound?

yes and no. It really depends on you.
I OCed my 5870 from 850/1200 to 870/1250 @ 1.2V and i gained about 10 to 13 more FPS and its very very stable.
BTW my Voltage is set to 1.2V on my 5870 and i cant change it cuz its a non-reference card.

50 MHz increase only and 10 whole frames increase? Holly molly what in the hell. Are you sure? If I overclock my card/s by 50MHz only they'd laugh at me and go back to stock since it's practically the same deal.
