Multiplier went from 10 to 7.5 on its own. Why would that happen?

[floydianSchlip]

I recently built an AMD rig for a friedn of mine, he's running a 1.0 Ghz 266 FSB retail CPU on a ECS K7S5A and it worked fine till recently.
A few days ago while booting up he realized that his clock speed was showing up as 750Mhz. I went into the bios and found that the multiplier had somehow gone to 7.5. It is an AMI bios and does not offer me the option to change the multiplier. I was thinking of flashing the bios, but right now we're having finals so he doesn't want to mess with the machine until he gets his work done. I was wondering if any of you guys knew why this would happen.

Well, if it's a 266 chip the multiplier should be 7.5...(7.5x133=1000) it must be at 200 bus speed now...dunno why, but change the bus to 133 (assuming the BIOS lets you) and
it'll be right.

Yup, your BIOS went to defaults. Maybe you reset it, or the battery is bad?
