V-core sagging on Intel D845PEBT2!

"Intel Active Monitor" is telling me that my vcore is at 1.47 to 1.48v, when it is supposed to be at 1.525v...
Is this a problem with the software, mobo or power supply?
My last Asus board always had inconsistent v-cores as well.
I this bad for the CPU (2.66ghz C1 chip) or just faulty readings?
Thanks.

Is that under load? The Pentium4 is designed to request lower VCore as its current draw rises, as you can see from table 2-7 of the P4 Northwood datasheet At a draw of 50 amps, for instance, the VCore should drop between 0.095 and 0.173 volts by design.

Thank you for that article, just what I wanted, now to read it!
No, my numbers are at idle not under load, I guess I should test that too!
I must add, that I have had this board for 30 hours now, used Asus, Abit and Gigabyte boards before and this is the most stable!

Stability is what you get from getting an Intel branded board.
They did a pretty good review on it in a recent Maximum PC. I read that Intel went a little overboard, and actually allowed some tweakable memory settings on this. Is this true??

Yes, you can adjust memory speed and memory timings.
Right now my CPU is overclocked to 2.773 (5mhz fsb).

I just read a review on this board.. Supposedly, there is a "Burn In" mode in the BIOS.. It increases the bus by 4%.
This may be my next board.. upgrading from an Asus P4B266

I have my board on the 4% burn in right now, and have a 110mhz gain. That would be classified as overclocking if memory serves me right ;). Looks like Intel is getting their head out of the sand.
This board replaced my P4B266 (which can be found in the F/S forum) and I would take my new board any day. Much more stable.
