This board is a piece of gold!! Truely one of the best I've ever tested with a QX9650. What an FSB killer!

I've tested several boards so far and sometimes felt it a bit monochrome as differencies weren't very clear. But things are clear with the DFI LP DK P35-T2RS. Difference is real.

Check this figure to compare.




Just amazing...

So; I'm not yet fully confident with the board. BTW, I've started playing with it under cold. As I've said already, FSB was the first good point; then the second was CPU temperature monitoring... Yeah, the temperature as shown by speedfan or the bios, looks very accurate even at about -120C.

Nothing is perfect... And obviously, the DK P35 isn't. The voltages aren't very good on this one. I mean, CPU core set to AUTO+0.785v corresponds to 'only' 1.81v actual; same matter with vDDR... 2.50v bios is in fact 2.39v actual.
