You are very welcome! I find that advising people about any type of hardware
or software problem carries far more weight if you have the documentation
and web links to back it up. To quote an old newspaper axiom, check your
sources and be sure that any statement can be substantiated. I have read far
too many newsgroups over the years that have seen users make statements that
were more opinion than fact.

In this case I was fooled by the manual too until I did a bit more digging
around.

Glad to help out in my own simple way.

John O.

yes, that`s right. john understood what i was on about and realised that i
didn`t know intel boards have selective backwards compatability unlike amd
ones.

The OP is right, the manual does indeed state that this mb supports
800/533/400. Just a couple of thoughts though. Do you have the CPU fan
connected to the CPU fan connector on the MB? If I read the manual
correctly, using 333 RAM is only allowed on DDR 1 and 2. You can only
use
all 3 RAM sockets if using 266 RAM. Also are you sure that the MB is
not
grounding against the case at some point? Check all of the standoffs
and
be sure that nothing is touching the MB at a point where it could
chassis
ground, a ground that is obviously not supposed to be grounded.

And FWIW:

Now having stated the support for the FSB speeds in my post did you
see
the notes on that web page...to repost:

P4VT8+ Motherboard that has either the Prescott 800 support sticker on
motherboard or the Prescott 800 giftbox sticker on the giftbox pack
ONLY
supports Prescott FSB800 CPUs .
P4VT8+ Motherboard that has both Prescott 800 and Prescott 533 two
support
stickers on motherboard and both Prescott 800 and Prescott 533 two
giftbox stickers on the giftbox pack supports both Prescott FSB800 and
FSB533 CPUs.

thanks john, you`ve solved my problem. i do indeed have the board that
only
supports prescott 800MHz chips regardless of what the very rubbish
manual
says. Many thanks.
