Using a 1333mhz CPU on 1066 MB?

Try updating BIOS. If that doesn't work, you might need a 1066 MHz FSB processor.

the updated bios says it still wont be compatable, but if i overclock the motherboard then put the new cpu init, will it work?

Spend $75 and get a new motherboard! Solved!

You update BIOS and find out if it works. The board can be forced to FSB-1333 quite easily, but that only helps if the system boots. So update the BIOS!

Yeah, update the bios. That part is free. After that try installing the processor. If it boots up then go into the bios and "overclock" it to the 1333 FSB.

cheers for the guys, doing abit mor research n this subject, if i was to run the computer with the celeron, then goin into bios, increase the fsb from i think 266 to 333, then swap the cpus, you guys reckon it will work or will it auto revert to 266? also will the new cpu be runing at 1066 or 1333? cheers

It has nothing to do with the bus speed it's set at. The processor will work at FSB-533 (133MHz), FSB-800 (200MHz), FSB-1333 (333MHz), etc. It will even work at odd bus speeds in between. You can set it anywhere you want and it won't make a difference in whether or not it boots.

It's all about BIOS programming. If the did it wrong, your CPU will be detected as incompatible and the system will refuse to POST. If they did it right, your CPU will be detected as incompatible but your system will POST. All you can do is update BIOS and try it.

I thought you already had the CPU. If you don't have the CPU, why waste our time?

Ah, to put it more gently, if someone doesn't own an FSB-1333 processor they can instead choose an FSB-1066 processor of similar price for their FSB-1066 motherboard.

at the moment i have both cpus, i initially bought the 1333 cpu thinking it will work with the MB, so then i bought a celeron cpu to see if there was anything wrong with the mb.

So why didn't you update the BIOS and see if it would POST, rather than working "in theory"?

*sigh* he's like one of those people that cheap out on psu's to find out that it either dies and takes half their system with it, or can't even juice it up through POST.

look computabug, i didn’t cheap out on anything, at the time i bought the most expensive components out, that’s why i want to get this to work, if ur going to be unhelpful don’t respond.
crashman, the reason why i am working in theory is coz i don’t want to keep swapping the cpus around. cheers

There is only one thing you can do: Update BIOS and see if it works. That's only one swap. If it does POST, you can set the FSB as required to 333 MHz (FSB-1333 is 333MHz). If it doesn't POST, there's nothing you can do to fix it.

CPU support has nothing to do with the speed of the front side bus, CPU support is chipset specific.

Find out what chipset your mobo has and do some research at the chipset and mobo makers website to determine if a 1333fsb cpu will work.

Yes, it's that easy!!!!!!

noobs...
