AMD Phenom II X4 810 & X3 720 Processors

Overclocking:

Since the Phenom II X3 720 chip is a Black Edition (unlocked multiplier), I simply used the AMD Overdrive tool to increase the multiplier and adjust the CPU voltage. The X4 810 has a locked multiplier, thus the only way to overclock it is to increase the HT reference clock. For air cooling I tried a Zalman CNPS-9700 and Scythe Infinity. Unfortunately because of some other unforeseen issues (not related to this review) I was not able to do as thorough of overclocking as I would have liked. Overall I'm quite pleased with the results, and they seem to be in the same ballpark as others.

Here's a breakdown of the numbers, all tests were done on air (as mentioned above):

• X4 810
  • 2.6 GHz / 1.325V / 200 HT = Stock
  • 3.06 GHz / 1.325V / 203 HT = Max Stable OC @ Default Voltage
  • 3.4 GHz / 1.525V / 262 HT = Max Stable OC
• X3 720 BE
  • 2.8 GHz / 1.325V = Stock
  • 3.3 GHz / 1.325V = Max Stable OC @ Default Voltage
  • 3.7 GHz / 1.50V = Max Stable OC
