The P55H-AK has a wide range of voltage settings and a high-enough frequency ceiling to assure that the overclocking limits of nearly any LGA 1156 processor can be reached.
Though the BIOS menu of the P55H-AK is advanced from ECS’ previous high-end attempts, it’s still a little basic compared to its hardcore competitors. Little items, such as having to set the “Performance Level” to Enhanced just to unlock multiplier controls are somewhat annoying.
Simplicity can be a good thing for beginners however, and we certainly found enough adjustments to set up our processor just the way we wanted. DRAM, for example, was changed to DDR3-1600 at CAS 7-7-7-21, using a 200 MHz BCLK to reach a CPU clock of 4 GHz.
A 1.38 V setting allows our Core i7-870 to run happily at 4 GHz at low heat, producing an actual voltage of approximately 1.36 V. A 14-phase voltage regulator keeps the system extra stable, just in case we need more.
ECS includes three flexible SLI bridges, allowing builders to configure three-way SLI by using the longer bridge to cross the other two bridges at the center card. The extra-important front-panel USB 3.0 breakout plate is also included, along with a slot-panel adapter for those who prefer more connections out back.
