9NPA+SLi vcore fluctuations

I've been hearing about this lately, and just wondered if these boards might simply require a tighter regulated (very stable voltage output) PSU to solve the problem?

Look here: http://www.aoaforums.com/forum/epox-...9npaj-sli.html or here http://www.aoaforums.com/forum/epox-...-9npa-sli.html

It's not a bug, it's a feature...

That's a coincidence, because right now on this ASRock K7S41GX I get vcore readings from 1.1616 - 1.664v in CPU-Z. That's a .5 volt swing!! But it doesn't seem to affect anything adversely, so I'm not going to worry about it. Looks like EPox mobos are not the only ones with these voltage variations.

Thanks for the links.

The EPoX Support told me, the vcore fluctuations are definitly not a problem of the potential transformers (five-phased on the 9NPA+ Series) like during the nforce II series.
But the ASRock only got a three phases potential transformer, so this could be the problem of the ASRock board.

A friend of mine got this curious ASRock board with AGP and PCIe and he complains of really enormous fluctuations, but also of VDimm. This flutuatic VDimm destroyed his MDT Dimms...

VDimm is very stable with the 9NPA+, so the explanation from the support makes sense.
