Thumbs down Epox 4G4A+: bad voltage regulation -> bad OCing

I have my P4 2.26B up to 2.72GHz (17x160) stable on this board but I have to use 1.85V in BIOS. It's at 1.82~1.84V idle and dips down to 1.74V underload I think it is because of the lack of the 12V 4-pin plug.

At first I thought I had a bad 2.26B (Malay 06/06/2002 SL67Y) but my friend who has the same chip got it to 3GHz stable at 1.725V on the Gigabyte 8IGX and 3.2GHz for Sandra. Today I tested my chip on a friend's Abit BD7-II. Guess what, the chip did 2.75GHz (17x162) rock stable at 1.6V !!! I believe with the pin mod, I could get the chip a lot higher on that board. Btw we all use the same PSU: Antec TruePower 480W.

I've used quite a few Epox boards: 8K7A+ (had 2), 8KHA+, 8K3A+ and now 4G4A+. This will be my last Epox board. All of those boards have voltage problems: low Vcore, low VI/O, fluctuating voltages etc.

I've always considered myself as an EPox fan. I like Epox boards for the features and good pricing. However, it seems that these boards are not engineered properly to handle the features they have (mainly talking about overclocking supports). It's sad I hope Epox will improve this in the future.

Goodbye Epox

I wonder why most Epox users and reviews on the web agree that epox are the best (or at least near it) for overclocking. I wonder why the no-name company suddenly is a worldly known name.

Maybe you are missing something that others arent.

I get that too.

see here
4G4A+ vcore dips by 0.1v on load?

but I thought the general opinion was that such voltage drop was normal for P4 boards?

If your going to give up at the first hurdle then your not much of an overclocker....

Please read this
4G4A+ vcore dips by 0.1v on load?

Have you used the same PSU (or PSU of similar quality) on all your Epox boards ?
Maybee you have a PSU issur rather than a motherboard one ?

The power regulation on the 8kha+ 8k3a+ and 4GLM+ have been absolutely spot on for me.
You may also want to measure your voltage with a multimeter as the onboard sensors can be innacurate (as on my 8k3a+ that reads 0.1 to 0.2v too low on all lines)

greenberet's using an Antec Truepower (isn't that considered to be the best right now?) I'm using an Antec/CWT 420W..aren't these both reliable psus?
