At stock memory performance lines up with our other motherboards as you'd expect. Overclocked, we see the performance actually drop back a little, though.
Replacing Everest in our labs is AIDA64. This new testing suite is from the core development team from Lavalys and continues that tradition. The guys have thrown in better support for multithreaded CPUs as well as full 64 bit support. We use this to test memory and HDDs for now, but may find ourselves opening this up to other areas of the motherboard.
AIDA64 shows similar happening to what we saw in Sandra. At stock it lines up fairly close with our other boards, while overclocked shows little difference and write performance actually drops down just a little bit.
