Which P35 mobo's have the least Vdroop

Was curious to see what other people's vdroop are and what Mobo's you are using. Overclock/stock both are welcome.

And if you don't know vdroop is, its the difference between what your CPU volts say in your bios vs your CPU volts in a program like CPU-Z etc.

Mine is overclocked to 3.2 @ 1.375v in bios with a vdroop 1.28v making almost a full .1 droop :( mobo=p5k se

Does anyone notice a trend if a particular mobo manufacturer has less droop?

I was asking because I think my mobo's ability to control vcore is limiting my overclock.

e2140 3.2=400x8@~1.375v 65c load

At 400 Mhz you could be hitting the fsb wall of your chip. Test this by setting your multiplier to 6x in the bios before raising the bus speed. Your current 100% over clock is good for these chips.

I have one chip doing 391 fsb tops at stock vcore. It locks up at 392 fsb regardless of the voltage. My E2140 just gets over 400 fsb before it too hits a wall. You can POST higher, but any stress test will lock it right up. Something about the package I think (fewer capacitors?, who knows!).

There is Vdrop (idle BIOS setting to actual) as well as Vdroop (idle to load).

That seems like a lot of droop for a dual though & more reminiscent of a quad.
Could also be your PSU having an effect though.
