I had one hell of a problem before, and lowering to 667 did help. But like 4-5 months later I was able to re-raise it to 800 and it worked, who knows why. Try the 667 thing.

Came downstairs this morning, and saw that it was still up. Shut it down, and dropped in the other 2 identical sticks of RAM. Reboots failed (bluescreen on boot) for both Vista and Server 2008. NB voltage was already at 1.39, taking it to 1.5 (next step up) didn't help.

Anything else I can try? Would forcing the memory to run at 667 instead of 800 help?

take the sticks that you added and run only them. It's possible that they are bad sticks. Memtest86 is a great way to detect bad memory.

could also be dodgey slots, test each stick in each slot to see if its the board not the ram.

Both good suggestions, and ones I'll do when I get home. I just "assumed" that everything was working good out of the box - but you know what happens when you assume...

This is slightly offtopic from steelforce's problem (ok, very offtopic). Is it possible to run a graphics card in the second PCI-e slot on the P5N-E Sli? It's a hell of a lot more convenient to run it in the second slot in terms of ease of cooling. I tried it, the computer booted and all but the card wasn't giving any video signal (Only reason I was able to tell it posted&booted was b/c after about 30 seconds I heard the vista sounds).

And no that is not your nb voltage. In the bios you should set it to 1.39. 1500 is close enough to 1600 that it may need a little extra juice. But first try with the extra vcore.

edit: Wait, you have the vcore on auto?

Thanks for your help dude
I was able to get it to 3.0 GHZ. It has been running stable for about a week now. I have stress-tested it thoroughly, I think, with no problems.

What is your opinion of updating the BIOS if my current one appears stable

If everything is working fine I would not update the bios. Only upgrade it if you need support for something like a new cpu that isn't supported by the current bios.
Congrats on the successful oc! What voltage are you using?

Now the Vcore is set 1 set up ( +.00625 ) to =1.406325v
it was =Auto.

CPU-z is reporting it as 1.408 and Everest at 1.41 V.

And yes, that is what I thought about the BIOS question. "If it ain't broke, don't frak with it".

Sounds like a good voltage. I would check with a program like coretemp (if you haven't already) to make sure your temperatures are ok...I imagine they would be with your current hsf.
edit: (deleted some text)oops forgot you stress tested it....

if its single card mode only the top slot is supported unfortunately
