Intel Core i7 supports up to 1066 DDR3

jmke · 2nd September 2008, 14:33

We were surprised to see that the Bloomfield generation of CPUs will officially support DDR3 800 or 1066. Even the extreme edition 3.2GHz Core i7 officially only supports DDR3 1066 and not faster. There won't even be an official support for DDR3 1333 not to mention 1600 or faster. Bloomfield Nehalem doesn’t run with DDR2 memory as the memory controller is inside of a CPU and so far we are not aware of any plans to release Bloomfield Core i7 CPU that would support DDR2.

"Fudzilla has already mentioned the fact that for some reason you need to run memory CPU voltage synchronously which might be an overclocker's worst nightmare. At this current stage you cannot go over 1.65V and some memories such as DDR3 1600 or DDR3 2000 might need a bit more than that. With more than 1.65 you will kill any current Nehalem CPU."

Is this confirmed? If so, that's possibly the stupidest design decision I've heard of in a while.

No, it was disproven. Intel also stated DDR3-1333MHz operation is confirmed for the Extreme chip.

So the RAM + CPU don't share a voltage setting? Thank god.

From what I can tell, nope. It should apply to the CPU voltage setting and not the memory voltage, from what I've read. We'd be in big trouble with 1.65v only memory, otherwise...
