Older AMD CPU related question

[Sandan]

This may be elementary to many of you but I don't know the answer. I have an Abit KT7 board which I put in a system for one of my kids. I want to upgrade the CPU. The board specs says it can handle an athalon or duron cpu with a FSB of 200mhz. If I got an athalon cpu with a 266 fsb would it be backwards compatible and run on this board? Thanks for your help

The specs on Abit's site say that it takes PC100 or 133 memory, so it should handle a 266 Athlon just fine. A lot of older boards will have a jumper somewhere near the cpu or northbridge that lets you change clock frequencies. Might want to wait for someone who actually has one to speak up, though, this is just a long winded bump 🙂

I'm downloading the manual right now, I'll let you know.

EDIT: It looks like you'll need a 200MHz FSB chip, but I'm not 100% sure. Try giving Abit an email.

Thanks for the info guys. Anyone with the board who is using a 266fsb or knows for sure? Thanks.

You can get a 266 Mhz CPU and use the pencil trick to unlock the multiplier, so would be able to set the fsb at 100 and change the multiplier to reach the frecuency of the processor you buy, you can get the Athlon 1333 266MHz FSB, which cost US$42. If motherboard doesn't allow you to change the multiplier you can get an Athlon 1300 200Mhz FSB, which is also cheap, US$57.

It will be definately be backwards compatible but like carlosd alluded to, it might not run at the spec'ed speed. Depending on what you're upgrading from, you might be better off upgrading the whole shebang.

KT7 used the first via chipset, it was the KT7A that did 133 mhz fsb. IIRC, those KT7's never made it past 115 or so on the fsb so you will have to get an unlocked chip and raise the multiplier or run the chip at lower then stock, like the last 2 posters said.
