Memory performance under Sandra looks good considering we're dealing with only Dual Channel here and not Triple Channel like the X58 platform.
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.
While only Dual Channel, memory performance has become so strong on the P67 platform and you can see that here.
