HD 5870 overclock and temp questions!

post #1 of 3
Thread Starter 
Just got an HD 5870 installed, along with my new PSU and I was wondering what kind of modest overclocks I should expect and what temps are normal at idle and load.

I opened MSI Afterburner and the stock says 850 core clock and 1200 memory clock. The core can be put up 50 and the memory up to 1300 clock. Is that normal?

Thanks!

Yeah, that's normal. Your temps shouldn't exceed 85 degrees if you overclock it by a lot, and on stock, I wouldn't expect it to get above 65-70. Those are for load. Idle, expect anywhere from 30-45 degrees

Factory overclocked versions of that card, like the Vapor-X series, start at 875 core and 1250 mem... I own a reference card and a Vapor X, and they both are good for 900 on the core without much effort, memory isn't usually quite as tweakable as the VRM temps already run a bit hot, and pushing the memory seems to heighten this problem. I tend not to push that as much... 

 

If you run in multi-monitor mode, be aware that you may see some screen tearing weirdness in 2d after you run something overclocked. The 5870's have an odd bios "power saving" setting that defaults a bit too low for multi-monitor setups. It can be tweaked... There's a good discussion on this in the driver section under 5870 or 5970's...

 

Enjoy!
