Compatibility DDR3/Core i7 920

[ev0styLe]

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?

Cheers.

Im confused becoz im not a big overclocker, havent explored it yet so at the moment im trying to wrap my head around this. Are u saying its down to the motherboard whether the cpu detects memory speeds?

"We've split testing between a Core i7-920 and 965 Extreme due to the former's lack of official support for memory faster than 1066MHz. Core i7-920 and 940 processors have a maximum memory speed of 1066MHz that motherboard makers haven't yet found a way to circumvent, but the 965 Extreme is free to use multipliers that run its memory bus at 1333, 1600, 1866, and even 2133MHz."

Still very confused as on Intels website it shows that the 920/940 chips on die memory controller only supports up to 1066MHz?

Sorry if im missing something really obvious here? Does CPU memory support not mean anything? Does this have something to with a 1:1 ratio with CPU and memory frequencies?

But then again i thought these new i7 chips dont have a FSB? Could someone enlighten me please

Cheers.

Some people claim 1600MHz DDR3 are easier to overclock due to the 200MHz base clock frequency.
