Intel X79 Quad Channel and Z68 Dual Channel Memory Performance Analysis
 

Memory performance on the new platform has been all over the place and I've personally been talking to both motherboard and RAM manufacturers to see what we can do about the performance. The big issue at the moment is under AIDA64 - an almost industry standard benchmark for us, we see that Quad Channel isn't painted in the best light.

It's not our job to go out there and make sure the product is painted in the best light. It's not like Intel has turned around and said anything to us, though, it's just this personal issue I'm having at the moment with the numbers we're getting out of Quad Channel memory in our normal benchmarks. It doesn't make sense that from a bandwidth perspective it offers no more performance than Dual Channel, if not slightly less at times.
