Would 1.8-1.9v memory produce a lot more heat than 1.65v memory?

Would this raise the temperature inside a typical case by a lot, or would the difference be negligible? Many thanks.

From what I remember its 20W a stick total maximum, realistically, 10W, 10% more V? Maybe 15W...

So no it wouldn't make any diff really.

Brilliant, thanks very much Concorde Rules.

What system are you considering the high volt stuff as compared with the low volt stuff?

i7 main limitation is the voltage needs kept low so chip isn't dmagaed, not the memory.
Probably not related, but just wishes to state.

That has proved to be not the case. Intel said 1.65v on the mem, so as not to damage the IMC. But it has now been found that as long as you keep VTT/QPI within 0.5v of the Ram voltage, it dosn't cause any damage to the IMC.

Ah very interesting indeed, I wasn't aware of this.

Sorry for the late reply guys. The memory is for a Phenom II x4 955.
