I see. So if I switch this stock HSF with my OCZ Vendetta, I should be able to hit higher clocks, correct?

BTW, I found out that the Athlon II series can really only handle up to DDR2-800/DDR3-1066 (which is in the specifications). I just got a pair of G.Skill Tridents that run stock at DDR2-1066 (1066MHz) @ 5-5-5-15-48-25, 1.8v, EPP. (Sexy coolers, BTW.)

Using the stock CPU speed of 2.8GHz, I tried forcing the RAM to run at 1066MHz instead of 800MHz (which I guess the CPU forces the BIOS to set it to), and the system will not POST at all. It's only when I overclock the CPU that I can get the RAM higher than 800MHz, but obviously it'll still be running slower than it's rated timings. I guess I may have to move on to a Phenom II which natively supports DDR2-1066.
