Summary: These are great processors. Yes, they may be a little high on the wattage scale, but they are extremely stable and reliable. I was able to unlock all 4 cores and Prime95 burned in each core without errors.
Summary: Unlocked all 4 cores with MSI motherboard and am overclocking to 3.85 ghz (17.5 x 220). Just a nominal overclock with this processor. I was up in the 4 ghz range but not stable with my video. I'm not well versed on fine tuning vga and memory settings.
