Pros and Cons of Digital PWM?

[STaRGaZeR]

I don't know how you measure 0.08V ~ 0.1 Vdroop , but even so , it's not way tooooo big to cause system unstable ...

Check this to have a good understanding about Vdroop ... http://www.xcpus.com/forums/intel/14...epository.html

Yeah, I know how Vdroop works, and I really don´t want it. Stable voltage is best for us XS members. Asus, DFI, Gigabyte... must implement an option in the BIOS to let us rock stable voltage under load, or a max of 0.01v~0.02v, like CPU Voltage Damper does in lastest Asus boards.

I measured it with the Smartguardian utility, didn´t know how to read it with a multimeter. Anyway, SM confirms what I saw in my tests: with the same CPU, Asus and my current Intel board behaviour is the same. Both measured with a well calibrated multimeter, after vdroop it needs 1,19v to a stable 3.3Ghz, a little 24/7 OC. With the iCFX3200, 1.35v in BIOS resulted in a 1,28v idle (no problems here, typical Vdrop), but at load, it dropped to about 1,20v. At that voltage it should be stable like it was on Asus and Intel, but it wasn´t, 1,25v or 1,30v under load didn´t fix it. Even at that low OC, that huge voltage fluctuations kill the stability. I played with the iCFX for about a month, trying to understand what I was doing wrong, but honestly, I think that the problem was a faulty board or something, not me. I really liked all the BIOS options, great board, but the voltage related stability issue forced me to get rid of it.

PS: Anyway, there are any proyects of VRM v2 or something like that, to fix current VRMs minor problems? I really like clear CPU area and reduced power circuit area too. If a board with it can disable Vdroop function, I will buy it, and more people too IMHO.
