DFI 680i LT vdroop mod

Preferably pencil, I just need to send a stable 1.42V to my proc, because it will "rounding fail" prime on one core if it drops to 1.41.

As far as I'm aware VCPU droop is build in into processor specification. It means that vdroop must exist. Why don't you just raise your vcore to 1.45?

well i can't maintain 1.42V constant, even if i raise the voltage, if i raise the voltage to 1.52, which gives about 1.43V under load, it will still ripple and give me 1.41V after a hour under load, causing a rounding error in prime95. i cant just set a higher value and get an expected CONSTANT voltage under load, so im hoping a vmod would help.

You are misinterpreting the concept, vdroop must exist if the Vcore regulation circuitry cannot cope properly with fast transient loads; it's a method of protection, the voltage droops in load so when it exits load rapidly it won't overshoot too much. Well built & solid regulators should have no droop.

As for the EVGA motherboard, the problem is not really the droop as it's not that big, it's only that it sets way less voltage than you want. Anyway, this (http://www.xtremesystems.org/forums/showthread.php?t=154897) should work on the LT too.

nope, the dfi 680i is not a reference board, cant find an ADP chip.

Bump... anyone have any idea how to mod this board to reduce Vdroop?

aww i clicked on this thread hoping...
