Core i7-870 Overclocking And Fixing Blown P55-Based Boards
By

While the focus of today’s article is power-draw increase due to overclocking, a few users won’t be satisfied unless they see the actual performance increase. For that, we repeated the full benchmark set from our previous motherboard round-up.

Test System Configuration
CPUIntel Core i7-870 (2.93 GHz, 8.0MB Cache)

Thermalright’s MUX-120 cooler is barely big enough to cool our fully-overclocked i7-870 processor at 1.45V under the stress of eight Prime95 threads, even with an ambient temperature of 22 degrees Celsius.
