Hey gusy, I'm thinking on overclocking my HD3870 and I'd like to know, whats a good idle temp for this card? load temp?
 
I would say a good load temp would be mid 70's. Thats about what mine runs. I run 837/1143 24/7. I would go higher on the memory, but COD4 seems to be picky if i turn it up above 1150
 
Me? i use CCC to set my clocks for my everyday use. But if i need to benchmark i use rivatuner or AMD GPU Clock Tool, CCC max setting for me is 837mhz.
 
Thanks, and how do you monitor your load temps? is there a GPU stresser or the like?

Hey btw Corey, off topic, what are your RAM timings? I'm thinking on losening mine a bit and try and go high on the frequency...
 
i run my ram 5-5-5-15.

For temps, i open rivatuner monitor and let it run in the background while im playing a game. Then you can look over the graph to see what the load temp were. :)
 
Ha! didn't think about that, thanks. :)

Right now I'm @ 796/1161 (never oc'ed GPU before) played COD4 for about 2 hours and I had no problems. Only thing is that I didn't know what my temps were.

I'm idling at ~58C, is that too bad? (fan manually set to 50%)
 
It is a little high for idle but it's nothing harmful. I'd check your load temps before you jump to any conclusions.;)
