Need help on Asus P4P800SE

post #1 of 7
Thread Starter 
I am new at overclocking. My problem is when I adjust my Vcore above 1.60 and have my FSB at 155 or higher my system on reboot has the moniter go into standby mode and does not post.

My voltage is good across the board. Does anyone have any ideas as to what is going on?

Seems like your RAM can't keep up. Try a RAM divider.

I would say that your processor does not like such a high vcore. That 2.53 is a Prescott @ 533FSB?

Your ram is PC3200 (OCZ 400MHz) so I doubt that is the problem, but if it is a Prescott certainly 1.6V is very high.

Have you set your PCI/AGP bus to 33.33/66.66?

Definitely locked the pci/agp bus to 33/66. It is a northwood core running at 533 bus speed. I think you might be right Ropey it just does not like the higher voltage. I think I might have it the top .

The Northwood and P4P800 SE sometimes have a block at 1.6V. Try 1.65V to see if that is the issue.

The Northwood is fine with 1.6 - 1.65V on good air cooling. Watch your temps though.

You can take a Northwood up to a max of 1.7. Do not go over that though at all and even try to avoid 1.7 if you can as your temps will get a little to hot..From what i ve heard and what was said above also the Asus boards are actually very lame sometimes as they are picky as to what coltages you can set.
