No surprise under SiSoft Sandra with memory performance being very similar across the board.
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 gives us a much better idea of memory performance and you can see at stock it again lines up with a lot of our other boards. Overclocking really helps yield some strong performance, though, especially in the write department.
