I'm hoping someone can provide some insight into my problem.
I was running an ASUS A7M266-D motherboard with a single Athlon MP 2400 (Thoroughbred). I recenlty purchased an Athlon MP 2600 (Barton) for the second processor. However, when I installed the processor and turned on the computer, the bios started emitting a constant beeping sound, as well as it says that the voltage that would be used could damage one of the processors.
Currently the vcore voltage is set to default by the jumpers. Would it make sense to vcore voltage to 1.6V (what the Barton requires), which would underclock the Thoroughbred (usually runs at 1.65V)?
