I have a server that blue screens when it starts to get into Windows Server 2003. The only perculiar thing is that it only does it when the FSB is set to 133MHz. If I turn it down to 100MHz it loads and runs fine. I am yet to try a BIOS upgrade on the motherboard as I am running a repair on the OS but I was hoping someone might have an idea as to what would cause this. I am running an AMD 2400+ (not my choice for a server. I have to work with what I'm given.) When the FSB is set to 100MHz the CPU only runs as an 1800+. Any assistance would be greatly appreciated. Thanks in advance.

Have a look around in the bios,and try to find the memory timing settings, that might need setting at 133 also, Just going off the top of my head here, I'll have to look into it a bit further.
