ASUS P5W DH - Problems + Fixes Thread

"...Thought someone did say 2206 gives 1.4V at AUTO (kindly confirm) which may make o'cing with EIST/C1E easier...

Not sure if you were looking for Q6600 G0 only, or just any quad
- 2206 BIOS; C1 and EIST enabled
- QX6700 B3 @ 3g
- OCCT v1.1.1.b04 (short 10min test)

Thank you very much for the info bichi, precisely what I wanted.

Tried out 2206 on my G0 Q6600 but too bad, Vcore values remained exactly the same as 2205 previously, varying between 1.15V idle and 1.25V load. So it looks like they upped the Vcore for B steppings only. Or perhaps diff. P5W revisions play a part, mine is the earliest 1.85V revision.

Whatever you read is wrong. The bios reads the VID of the cpu under load and uses 1.1625v idle. These are the EIST values. P5WDH Bios revision never changes stock vcore. The cpu itself determines this via the VID, which can be read in coretemp or everest. And by the way, lower VID is generally better.

... except when it comes to trying to o'c it higher cos this chip is confirmed stable at 3.2GHz at 1.30V on my Commando (lovely independent Vcore/EIST-C1E options).

Nonetheless thanks for the consolation, lawry.

3GHz is enough, 3GHz is enough, 3GHz is enough... my new chant. lol

Coretemp with EIST/C1E, load vs no load

Dude, there are no exceptions... (EDIT: Oh nevermind, I understand you now, you were talking about the lower VID is better comment. The information below is still useful though, so I'll leave it)

The change in vcore your getting from the VID is the result of Vdroop.

You can do what I did and Vcore mod the motherboard. Thus, I can run EIST but increase vcore above stock. (this also increases the EIST vcore by the same fraction too)

for example. The vcore mod provides a vcore 18/15 x Your VID.

So 18/15 x 1.300v = 1.56v under load (without vdroop)

EIST VID is 1.1625v so you will get 18/15 x 1.1625v in IDLE mode which = 1.395v
