At an Intel briefing today, we learned a lot more about what to expect when benchmarking Nehalem, and much of it answered the exact questions that have been lingering in my mind for some time. If you read our overview on Nehalem already, then you know the benefits of the tri-channel memory, but what about overclocking?
First and foremost, while the 'ideal' memory configuration for a high-end Yorkfield is 2x1GB DDR3-1600, the ideal solution for Nehalem will be 3x1GB DDR3-1066. Seems weak, but if you read my article last night (and I do recommend it), then you'd know that it's far from being the weak link here. It effectively removes any potential bottleneck, and in most regards, the I/O becomes the new bottleneck (one that's not really seen with RAID'ing multiple SSD though!).
