Benchmark Reviews: It is common knowledge that today's Intel Core i5 and i7 series of LGA 1156 CPU's are capable of achieving the 4GHz milestone. You should also know that to push past that milestone, and remain stable, you will need a high end motherboard designed specifically for that task. ECS ELITEGROUP have been around for many years but have never really been seen as an enthusiast brand. That may be about to change today, as Benchmark Reviews brings you the ECS P55H-AK Motherboard (P/N 89-206-Y66100), which is part of the Black Series offerings from ECS. As is the norm at Benchmark Reviews, we overclock the ECS P55H-AK to its limits and find out just what it is capable of achieving.
