P4P800 Parts compatibility ?

Assume I have a P4P800 mb and 2GB of PC2700 DDR 333 memory. What 3.n+ GHz
Intel CPU's can I run with this combination? Will an Intel P4 3.06GHz FSB533
work? How about an Intel P4 3.0GHz FSB800?

Thanks,

Download the manual from the Asus web site, and you are likely
to find a table like this:

CPU FSB DDR DIMM Type Memory Frequency
800 MHz PC3200/PC2700*/PC2100 400/333*/266 MHz
533 MHz PC2700/PC2100 333/266 MHz
400 MHz PC2100 266 MHz

*When using 800MHz CPU FSB, PC2700 DDR DIMMs may run only at
320MHz (not 333MHz) due to chipset limitation.

According to that table, three different speed settings for
memory are allowed with FSB800 processors. Two different
speed settings are allowed with FSB533 processors.

Always download the manual for a board before you buy, as the
contents of the manual are your guarantee of how the board
works. Check the BIOS features carefully, to see if the
adjustments you need are there. Even if you aren't an overclocker,
adjustments are still handy for figuring out why your system
isn't working the way you would like. A lot of the microATX
boards lack any useful adjustment, and all you can do is just
stare at your build and twiddle your thumbs, when something
isn't working right.

I am using a P4 3.0C on a P4P800 running at 3.675GHz (FSB980) with PC3700
DDR memory running at 490. All is stable.

Your PC2700 ram should work fine with a P4 3GHz-800 CPU, ram probably
at running 320Mhz speed.

I have a P4P800 with 3GHz CPU, and ran two 512mb sticks of matching
Crucial PC2100 (266Mhz) ram for a couple months, until I could afford
faster 433Mhz duel-channel ram.

Btw, the P4P800 may have a rough time with mis-matched ram installed.
Hopefully you have 2GB sticks of the exact same brand/model, or at
least 1GB, that'd do for a while.

As another post referred to, when/if you upgrade ram, be sure to
purchase what the manual recommends.

What's up with this?

I have a Gigabyte 8SQ800 and it would run my memory at 400 Mhz. Same
CPU P4/2.66 (533 FSB), same memory. But my P4P800 only allows it to
run at 333???

Running your memory at 400MHz would mean you were overclocking your
2.66GHz. The P4P800 is just running in sync with the fsb. What you could
do is try to raise the fsb in a manual overclock and try to get the fsb to
get to 200 which your ram will happily do, but most likely your processor
will overheat and be unstable (it is a 20% overclock, which has been
possible using C class P4s, but not sure about B class).
