So i have an Asus A7N8X nforce2 board that is upgraded to the latest bios (1010) and has the latest PCB (2.0). Everything on Asus's site says my new athlon 3200+ barton 400FSB should work on this motherboard.
I popped out my old 2500+ barton, stuck the new one in, upped the FSB from 333 to 400 and poof, computer crashes when loading windows. When i clock it back down to 333 FSB it runs fine, but the computer thinks i have a 2500+ barton in here, not a 3200 cause it's running at a 2500+ clockspeed.
What the hell is causing it to crash when i load windows? As far as i can tell cooling isn't a problem as the bios never shows my CPU above 40 degrees after a crash (and crashes don't normaly happen till 60?). I've got a nice $40 heatsink on the processor that kept my 2500+ at 44 or below most of the time, figure it should work for this one too.
So what is the problem? I increased the CPU multiplyer to 12.5 and now my compute thinks it's a 2600+. It seems the CPU can clock higher but the board doesn't like going to 400 FSB? Is there something else i have to change to make it work with 400 FSB?
Last hint is that when windows starts up again after the crash, it says something has been cause by a device driver, which is probably BS, since i have the latest mobo drivers as well.
Any help would be apreciated. I'd hate to think i spent $100 on a CPU upgrade only to have it work the same as my old CPU.
