[citation][nom]jtnstnt[/nom]I'm curious about the heatsink selection on the Phenom II. I looked up the Ajigo MF091 and it didn't look too impressive. While the Intel system gets the Thermalright 120mm True extreme. Whats up with that?[/citation]
The Ajigo sports a copper base, four heat pipes, and an aluminum fin array. You're right--it's not a particularly spectacular heatsink, though it was the best Phenom II-compatible cooler in the lab. As a result, I made it a point to mention that stepping up to a better cooler might have yielded better overclocking, but would also erode some of AMD's price advantage as well.
Heatsink aside, after talking to a number of colleagues from other sites at this year's CES, it sounds like the overclocks here are indeed representative of what others were able to do, even using different heatsinks. I'll look into getting more in the way of air cooling and hope for better results.
