Looking for P35 chip set MB with little vdroop

[EvilSponge]

Hello all,

My Abit IP35_E just has too much vdroop. Can people please suggest a replacement MB that has very small vdroop.

Many thanks,

The vdroop on my IP35-E is only .024. How much are you getting?

 

[EvilSponge]

Well almost 1 volt My bios setting is 1.5v cpuz reports 1.408 volts under load that's .090 aprox

The Vdroop is part of the Intel design spec, without it you don't get Intel accreditation.
You will need a mobo that allows you to get around that - some DFIs & Asus P5Ks (Deluxe/Premium) have BIOS options to enable/disable what afaik is addditional PWM circuitry that will do this but they are all premium mobos not $60 like the IP35-E.

As Heid said, you can only get that with the high end P5Ks and the High end DFI P35s.

Id just crank up the voltage a bit higher and enable the power saving features so youre not baking the chip when its not at load.

Yes that is exactly what I'm doing. It's just I don't like driving it at max speced voltage per the bios. I know it is totally stable at 1.40v so it would be nice if bios wise it was set there as well what I have noticed when I launch something and speedstep jumps the chip back to the 3.6ghz oc per cpuz voltage spikes sometimes to 1.45 volts then drops back.

& that is exactly why Vdroop is part of the Intel design spec., to allow for overshoots.
The voltage sensor is pretty accurate so whilst you have to set more in the BIOS to get it what the CPU is actually getting is what is being reported & not the BIOS setting.

Ah good to know. Well it would be nice if it spiked at say 1.41v opposed to 1.45v but hey it is a great value board got it for like $60.00 after rebate thanks for the replys

Can you enable SpeedStep without an issue? That'd solve your probme at least partially. vDroop differs per different CPUs and more demanding CPUs (such as your Q6600) will result in bigger vDroop of the board.
