FSB problems. Please help.

[Onlooker]

I'm using an AMD Duron 1.2 and an AMD Athlon XP/Duron MSI K7 mainboard. They are compatible, obviously, because my computer boots and works just fine. The problem is, I can only get my computer to boot up when the FSB jumper is on 100mhz instead of 133, its kind of annoying, and I really dont understand why the 133 setting isn't working. Is it some sort of compatibility problem with my Duron? Any help would be great.

It is because the processor is rated to run at 100MHz fsb. What you are trying to do, in essence, is overclock the system when you turn it to 133MHz fsb. If you are setting the processor to run at 133, then the system is trying to run the processor at 1600MHz. The 1.2 GHz's multiplier is set to 12. (12x100=1.2 / 12x133=1596) You may be able to set the RAM fsb at 133, but only if your ram can handle it. On that board, you can set the RAM and processor speeds differently, I believe. Faster RAM will improve system performance.

If you want to get into overclocking, we can give you advice on what settings might be best. Then you could get more than 1.2GHz out of the processor. But, I don't believe you are trying to do this now, so I will hold off.

Thankyou. I will check on that RAM FSB right now.
