I'm upgrading to the Sandy Bridge platform.
What I'm asking is, how do I figure out what speed of memory to purchase so that the QPI link is not bottlenecked? If a CPU is 6.4GT/s QPI, how do I find what memory speed is required? DDR3 speed is anywhere from 1066 to 2500. This is such a basic concept that I can't believe that I can't find information online explaining this. I know there has got to be a way to figure it because I just can't imagine buying a Core i7 SB CPU then sticking in 1066 DDR3 and have everything operate at it's highest performance.
Also, how does the bclk effect QPI? I understand SB bclk is essentially locked, but I want to know anyways.
This is a situation where I want you to teach me to fish, rather than simply giving me a fish. So please don't tell me to just buy the fastest I can afford because then I haven't learned anything.
Thanks.
