EVGA leads Asus in an extremely tight race for “best overclocking motherboard over $200.”
Intel has the highest base clock, something that should come as a shock to EVGA. The most likely reason some “top-overclocking” motherboard companies aren’t seeing the expected results is that we don't to alter CPU VCC for these tests due to the potential for processor damage, although it’s also possible that our particular CPU sample isn’t as base-clock tolerant as the ones those companies use.
Asus takes top honors in DRAM overclocking, followed closely by EVGA when two modules are installed. With four modules in place, Asus’ top data rate is unrivaled.
