Hi I just bought a new Mach-Speed socket 370 Mobo that supports up to a 1.4ghz celeron P3 processor @100mhz, and I also have a P3 Tualatin processor that runs at 1.13ghz but it has an system bus of 133mhz. I was wondering if I could still use the Tualatin P3 on the motherboard even though it has a diferent bus than is supported for the Celeron type of P3's. You can see the mobo and it's specs at, http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=602210&Sku=M450-1100&CatId=181 I don't have a link to the processor. So if you could tell me if I can still use the Tualatin processor or if I should just use the old coppermine CPU it would be greatly appreciated. Thank you

As far as I know there were no coppermine celerons made higher than 1.1ghz. I have a tualatin (1.1A) celeron which runs at 100 mhz FSB, and I heard the tualatin P3s run at 133 FSB (as you said). I think the board only supports 100 mhz fsb tualatins (celerons only). But I may be wrong. There are 10 kinds of people, those who count in binary and those who don't.

Of course it can!! "supports 133 MHz Front Side Bus and has been engineered especially for Intel’s fastest Pentium 3, Tualatin and Celeron processors." But beware, there are Tualatin PIII processors , named Pentium III-S, with 512KB L2 cache intended for servers that probably won't work with your mb. If your PIII has only 256KB of L2 cache will run fine. Hope this helps

Thanks dieymir, I guess I just overlooked that little detail, and the CPU is 256k so it should work. Thanks again
