>> DDR3 Round-Up: Memory Performance With The Core i7
There's quite a lot of variance in DDR3 modules today, which can certainly be overwhelming for potential new buyers. While the Core i7 processor is officially rated to run at only DDR3-1066 speeds, modules that can run at DDR3-2000 or even higher are available for the Core i7, and many new motherboards support speeds even greater than these. There is also the introduction of huge 12 GB (6 x 2 GB modules) capacity kits to consider, and we have latencies in the CAS 7 to CAS 9 range, all of which affect pricing of these various modules kits dramatically.
Today, we're going to look at some of these new kits and see if we can break down what memory-related aspects users should look for when buying an X58 / Core i7 platform. We've got kits from big names like Corsair, Kingston, and OCZ in the labs. Let's try to clear up some questions, shall we?
