Anyone know of a vdroop mod for the p45-ud3r? I have a massive issue with it on my board. 1.55 in bios gives 1.472 in cpuz... :mad:

That's interesting I have a p45-ud3p, and the maximum vcore that I can set in bios is 1.4v. I thought these board where the same, besides a few features. I'd love to have 1.5vcore.

Do you have "Line Load Calibration" turned on or off? Vcore shows low on mine, very low, with LLC off. I hear a lot about the vcore being droopy on these boards, but mine stays within a few thousandths of a volt, even under load (with LLC on). If its at 1.4v in bios, it shows 1.396 idle & load in windows.

Does anyone know the vcore read point for these board? I'd like to measure mine with a DMM. I have seen Vcore read low in windows & bios, but be spot on with a meter.

l33t p1mp, please do a macro-pic from PWM's IC area. What IC it has? ISL6336? It should be similar to EP45-DQ6: http://www.xtremesystems.org/forums/showthread.php?t=204968 (see my post there)

I'll get a pic.

@jess
Max for me in bios is 2.3. Not that I ever got close to that though. :lol:

When I give 1.55 in bios I get 1.472 in cpu-z. That's a massive droop.

1) Don't trust CPU-Z. Use DMM to measure real Vcore.
2) Drop is difference in real Vcore in idle and the one selected in BIOS. We can't mod that and don't need to. Just apply bigger number in BIOS to get wanted REAL value.
3) Important is Vdroop - difference in real idle and real load Vcore. That is modable ;)
