Subject:1800 MHz duron stability-problem

[C]

When I set the CPU´s Front Side Bus jumper in off-position, so it supports
133 MHz FSB, the computer is running at full speed (1800 MHz CPU), but not
very stable, when I set it in on-position (100 MHz FSB), it runs stable, but
only at 1350 MHz CPU.

What is the problem? Doesn´t the motherboard support Duron-processors with
133 MHz FSB, or what?

My specs:
DFI ak75-ec motherboard, in which I have recently installed a 1800 MHz
Duron processor. I have two 133 MHz SDRAM-modules (128 MB and 512 MB).
I have checked, that the SDRAM actually is 133 MHz in AIDA32.


Thanks in advance.

It could be a marginal power supply. The processor won't draw as much power
when it is under-clocked. Also, be aware that total power output of a power
supply is not as important as how much of that power is available on each
line. Or in other words, a 2 billion watt power supply might not be strong
enough for your CPU. -Dave
