vcore strangeness

so when i am under full load (prime95) my vcore drops to 1.376, when at idle it is at 1.440. I have it set at 1.45 in bios.

Also if anyone has any tips for getting to 3.6 it would be cool. My memory doesn't like to overclock so my only option is 400x9. I can get it to go to windows with bios vcore 1.525 but it fails prime95 in seconds, at least 3 cores do....

specs in sig...
 
not every G0 can reach 3.6G
especially w/ 4G rams (assuming it's 4x1G)

BTW
the vcore change is called "vdroop"
usually every board has it (and it's bad for OC)
you can minimize it by modding your mobo

its actually a b3 and yes it is 4x1gb. I know what vdroop is, but why would the voltage go down under load? I thought vdroop was just the difference between the bios setting and the actual. I don't really want to vmod my mobo. Please explain
 
Well if you can do 400 x 8 (hope your MCH has a fan) all you can do is try 350 x 9 and start working up 10 or 20 MHz at a time and testing as you go. You will get where you will get and that will be the end of it unless you go to water. This will underclock your memory a bit but CPU MHZ are more powerful than memory MHz. You could try raising Vcore a bit more but you are about where I personally draw the line.

Voltage drop across components in the Voltage Regulator circuit for the CPU is Vdroop. V = I x E at idle I is small, so the voltage drop across say a filtering capacitor is small. Under load the I increases greatly making V bigger and the drop across the capacitor is more, meaning less gets to the CPU. This is all considered by the board engineers and actually is part of the design to keep a voltage spike from killing the CPU due to overshoot by the regulation circuitry when it tries to keep the voltage stable when the load changes drasticaly and almost instantly.
 
another question... why do (as far as i can tell) only the nvidia based boards allow you to unlink your memory?
