Will 800MHz P4 run on 533Mhz board?

[bill1971]

Three questions regarding running a P4C on a 533MHz board:

Will a P4C 800Mhz FSB run OK @ 533 MHz, if the board is only rated at 400/533? (There are no BIOS upgrades to accept 800 MHz CPUs).
I guess the "microcode" may not be recognized either?

Board accepts PC2100 or PC2700 DDR RAM.

If there is an option in the BIOS to lock the AGP/PCI @66/33 mHZ, and I can bump the FSB to 200 (x 4), will this configuration OC and run @800 MHz, running PC3200 DDR, provided the proper CPU and RAM voltages are recognized, or at least, can be manually applied?

This board supports HT and Dual-Channel, but the only HT CPU
I can find that supports 533 MHz, is a 3.06 GHz, and I really didn't want to spend $225+ for the CPU, for this particular build.

Thanks for any input.

Dont know for sure but two things can be the answer to your question:
- It will but the CPU speed will fall to (EDIT*)533MHz
- It wont work with this board.

sounds like a lot of monkey business there..trying to put a sq peg in a round hole.

You already have the 800fsb cpu? Can you just get another motherboard instead?

Are you sure you've got the right processor ?
Intel P4 processors began at 1.5ghz. An 800mhz would be a P3, which wont even fit on your board.

800mhz FSB P4 comapred to a 533MHZ FSB P4 .. thats his question

You're right, Jon:

It is a bit of monkey business. . .I just feel adventurous. Maybe the HT just isn't worth the trouble. I just bought a 2.4B ($135) that should work fine. I also have a 2.8C - I guess I can experiment - I might even learn something. I just don't want to destroy anything!

Thanks for the input, guys.

I think it would clock your FSB down to 533 Mhz if you used this processor, I used a P4B in a 400Mhz only board and it ran fine it just clocked the processor FSB down to 400 which brought the cpu speed down from 2.4Ghz to 1.8Ghz. Nice cool temps too

[bill1971]

Right, Manford:

I completely forgot about that! And the clock multiplier on the P4 cannot be changed, correct?

Thanks.

[thronka]

yea, they cannot be changed. only the FSB can be used to underclock and overclock. Same with the P4 Celerons.

Drat! Intel has thrown a stick in my spokes of my wheel again!

Thanks for the info.
