Celeron D's or P4-1MB cache chips

yo, i've got a bh7 (pretty universally compatible board)

so i went out and bought a celeron D 2.4ghz 533fsb 256k think its the model 320
threw it into my bh7 (which is currently running a 1.6ghz 400fsb oc'ed to 2.0ghz) and when i turned it on, everything turned on and sounded ok except nothing showed up on the monitor and i didn't hear that beep.
so then i went and tried one of those p4 2.4a 533fsb 1MB cache chips... it was a pretty good deal, same as the celeron D, but that did the same thing.

tried abit's site for a bios update, but nothing new.

i have already decided to go with a chip that i know will work, but can anyone tell me why this is happening, or is there odds that i got 2 fried chips in a row? and this is just my dumb luck...
 
The BH7 isn't Prescott compatible. So the Celeron-D and Pentium 4 90nm 1MB L2 cache chips are not going to work.

Not all Pentium 4/Celeron's are the same. You've got 3 different cores, Willamette, Northwood and Prescott. Voltage requirements and thermal specifications changed for each type of Pentium 4 core. Bus speed is only part of compatibility. The socket 478 motherboards that will be compatible with the Prescott are all going to be 800MHz FSB capable boards. Yours is not.

Not to say that all 800MHz FSB boards will use a Prescott. The manufacturer had to build the boards to newer power specifications provided by Intel shortly after the 800MHz Northwoods were released.

Such specs weren't available at the time of the i845E's production run. So due to the fact that your board couldn't have been built with voltage specs in mind for Prescott a BIOS update that will give your board Prescott support will not be possible. You my friend either need a 3.06GHz Pentium 4 (The fastest CPU that your board can ever have) or you need a new board and CPU.

533MHz Prescotts were designed to fill a price point in between Celeron-D's and Prescott Pentium 4's with 800MHz FSB and HT. The 533MHz Prescott won't have Hyperthreading.

So basically you've got to upgrade alot more than your chip.
 
whoa, well that's good to know...i figured it could've been something like a simple compatibility issue, but i still wanted the more technical explanation on why, seeing as they're still P4 and all. but thanx for the info, and i think i'll just get a regular p4 2.4 and oc as much as i can and ride that til i get a new motherboard.
