By now, you should know that the ideal (and Intel sanctioned) way of overclocking a Sandy Bridge processor is firstly to get the right processor, which means one of the two 'K' SKU processors in the market now. While you can try to push the base clock on a non-K processor, the limited allowance will likely lead to more frustration than success.
The five high-end P67 boards here all allow users to tweak the voltages, with some having more detailed options than others. Generally however, unless you know what you're doing, the basic ones listed here are sufficient to get a decent overclock.
Model | CPU Voltage | DRAM Voltage | Other Voltage Settings |
ASRock P67 Extreme6 |
0.6 to 1.52V (0.005V steps) |
1.2 to 1.8V (0.005V steps) |
|
ASUS Maximus IV Extreme |
0.800 to 2.155V (0.005V steps) |
1.20 to 2.20V (0.00625V steps) |
|
ECS P67H2-A | -200mv to +630mV (10mV steps) |
-200mV to +630mV (10mV steps) |
|
Gigabyte GA-P67A-UD7 | 0.750 to 1.70V (0.005V steps) |
0.90 to 2.60V (0.02V steps) |
|
MSI Big Bang-Marshal | 0.80 to 2.155V (0.005V steps) |
1.108 to 2.464V (0.007V steps) |
