There’s not much to see in the P45T-A’s overclock menu, and most of the settings that exist are restrictive. We couldn’t even select DDR2-1066, and changing the memory timings to anything but the defaults prevented the system from booting. Thus, the ECS P45T-A is the only motherboard in this comparison to be tested at both lower speed (DDR2-800) and higher latency (CAS 5-5-5-15), and it’s fair to do so because those are the only settings that worked.
