Compatibility DDR3/Core i7 920
Hi, Intel have said that core i7 (920 + 940) chips only support DDR3 800/1066 MHz memory but manufacturers have put kits on the market clocked at 1333/1600 MHz? Only the extreme edition of i7 can make use of 1600 MHz DDR3 or higher, which having said also has an unlocked multiplier which puts it at a big advantage for overclocking over its siblings?
My question is, if i were to get a 920 i7, and 1333Mhz triple channel memory, would my cpu make use of as much as it can (1066MHz) and 267MHz go to waste?
This is in the wrong section.. Needs to be moved to cpu and motherboards.
To answer your question anyway... as far as i know, the 800/1066 speeds come from the base clock of 133 with a mutliplier of 6 or 8. If you don't OC your BCLK then those are the speeds that will be used depending on the ram mutliplier setting.
Someone correct me if I'm wrong but that's what makes sense to me. If you have DDR3-1333 then OC your BLCK to 167 to get 3.5Ghz (167*21) and ~1333Mhz (167*8)
I am pretty sure I can run my mobo @ stock BLCK and still have the ram @ 1333.
