Hi, I have been overclocking my XFX 6850 to play Witcher 2 today. Following the anandtech overclock article: http://www.anandtech.com/show/4002/amd-radeon-hd-6850-overclocking-roundup-asus-xfx-msi/8
, I have overclocked it to 940/1200 on 1.172V. Then, I ran MSI Kombustor (similar to Furmark) for 15 minutes, core temps never crossed 60C, no glitches. I couldn't figure out how to check VRM temps (GPU-Z and Everest gave some weird results that are too low), so I checked it with a finger
. The VRM heatsinks were warm, but that's it. What has really bothered me that the PCB itself was superhot - I could not even hold my finger on it and nearly burned myself. The cooling is more than adequate: the core was <60C and VRM heatsinks only warm.
Question 1: is it bad?
Question 2: I have a lot of spare small heatsinks left from Accelero S1 cooler, maybe I should just install them directly on the PCB (on the "back" side of it) to cool it?
Thanks for your input.
P.S. I have little clue about overclocking, I just set the parameters as stated in the article, which pretty straightforward to do with MSI Afterburner/Kombustor.
