yah that sucks they say no more than 1.65 Vdimm because mem controller voltage increases alongside that, accordingly. Possibly fry the mem cont. thus frying the chip. Hopefully they make some 1.5v JEDEC standard DDR3 that will be high performance without voltage jittering. Also there are supposed to be ways around this with QPI overclocking & without needing super volts on the Vdimm. supposedly there will be less jitter on x58 w/ nehalem than there is currently with high-clocked penryns. We need more vdimm to increase system stablity now, but we shouldn't on the next platform - or so I hear.

edit: might just make overclocking a bit trickier. :)

Maybe this is a GOOD thing. Memory companies may now release more quality high-speed DDR3 that actually meet JEDEC (or come close to) standards. :)

It's not that different that DDR/DDR2 RAM where you would generally prefer to pick up the same speed-rated RAM at the lowest voltage.

It's just as well. With triple-channel you got a shitload of bandwidth already at DDR3-1333 speeds, no need to go for DDR3-2000 @ 2.1V.

Personally I'd much prefer the memory guys work on improving latency over the current 2004'esque GHz race marketing dogma where DDR3 speed is the end-all be-all.

Some nice DDR3-1333 at 2-2-2-2-8 latency and 1.5V would be yummy.

2 things'll happen, at the least: motherboard manufacturers will add differing power buses to subvert cpu overload situations; and, new kits will be released to coincide with the i7 release.

According to something that I read that was from an Intel person that was quoted, they said that Nehalem's Core, IMC, and some other part (QPI?) all had INDEPENDENT frequencies AND voltages.

So if that turns out not to be true, I'll be disappointed with Intel.

Well it could be true and yet the max voltage for all components could still top out at around the same value (1.55V'ish).
