I am having trouble getting over 155 mHz on my P4B533-e board.

I have a 2.66 which did 155 @ 1.55v. Would boot into windowsXP and then reboot just before everything got loaded @ 157 no matter what voltage i use.

I also had a 2.53 that did 155 @ 1.6v.... would reboot in windows at 1.56 no matter what the voltage.

Here's my setup:

2.66 Intel C1 stepping
P4B533-E using 1008 bios
Asus Ti4200 (not oc'ed right now)
Enermax 431 PS
Audigy
Maxtor 80 primary
2 x 40g maxtor/quantum mirror
using onboard Land and Raid
2 x 256 OCZ PC2700 (tested up to 186mhz)

I am running memory @ 1:1, PCI/AGP fixed @ 66/33.

The 5v reads 5.16 in bios, PCProbe, and MBM.
The 12v read 12.13 in bios, PCProbe but 11.5~11.6 in MBM. Would MBM be more accurate then the others.

The VCore moves around alot. Right now @1.55v, idle around 1.62 and load around 1.53~1.56.

I have watercooling and never go over 35C @ full load, no matter what the voltage.

So, to repeat, 2 cpus stpped at 155 with low volatges. Both boot to windowsXP, but reboot before the auto launch are done. Usually when Norton AV is launched

Any help would be appreciated
