Something of a question on this....I'm running an AthlonXP right now, but think my overclocking may be being held back by my memory. So, I'd like to get newer sticks rated for higher FSB speeds - in fact, I'd like to get sticks I can keep using when I do my Athlon64 upgrade next year.
HOWEVER....my motherboard (in the Shuttle SN45G XPC) offers no memory voltage adjustments. It's 2.55v, period, that's all, end of story.
However, when looking for new memory, I was checking out Corsair's XMS stuff on Newegg, and it says the rated voltage is 2.75v. Odd, I think, that they have started showing the max voltage? But, no!
Taking a look at the spec sheet for the TWINX1024-4400C25 (http://www.corsairmicro.com/corsair/products/specs/TWINX1024-4400C25.pdf) and the TWINX1024-4400 (http://www.corsairmicro.com/corsair/products/specs/twinx1024-4400.pdf) and the TWINX1024-4000 (http://www.corsairmicro.com/corsair/products/specs/twinx1024-4000.pdf), heck, pretty much all of them - it seems to imply the voltage was set to 2.75 in order to *achieve* those latencies.
Am I misreading that? Or, do you need 2.75v to the ram in order to achieve those settings and timings? And, if so, how do you find what kind of stable ram speeds can be achieved on 'spec' DDR voltage?
Basically, what I'm looking for is ram that will run at the fastest clock possible with CL2 timings and at 2.55v.
