Strange change in overclock?!

post #1 of 12
Thread Starter 
Hey,
I was just resetting my overclock again after about 3 months and now my processor remains stable at 3.9ghz for a much lower voltage than before! How is that possible?

For eg-
EARLIER i required 1.424 for 3.9ghz
NOW i require 1.39 for 3.9ghz

I just changed the ram in between from 1333 to 1600 and downclocked it. Would that make a difference?
I was and am Stable on prime, IBT for over 10 hours.

Any suggestion appreciated.

THanks
:D

The memory controller is located on the processor. I don't understand exactly what you mean, but you went from 1600mhz to 1333mhz memory speed? If so, running a lower frequency stresses the memory controller and processor less. So this is why you need slightly less voltage to stabilize your system.

I mean I just switched my 1333mhz ram with 1600mhz ram(which I again downclocked to 1333)

No, as Memory controller is not on CPU but on NB (LGA 775 platform wikipedia FTW)..

It's some sort of a loos voltage regulation on that board..

Dropping voltage on RAM probably caused to push more Amperes trough Vcore which resulted in less Vcore needed for the same OC of CPU..


CHEERS..

Hi KingT,
But the thing is i've increased the RAM voltage to 1.66 from 1.5v.
I downclocked it from 1600 to 1333 because it wouldn't run otherwise.

Nevertheless, by downclocking RAM it needs less power to run (less Watts) so that extra power transferred to the CPU power regulation and Vcore..

And also that means less stress on NB (memory controller) which results in less power required for NB to run..
