Core voltage settings on the A1
« on: November 24, 2004, 09:51:54 PM »
My A1 is disturbingly unstable, so I'm looking into the core voltage as a potential problem. It's currently set to 1.59V, and I have no clue if it's correct or not.

It's an XE-G4 model, and the only things printed on the chip are "Motorola", "7450", and "A99236D001".

Anyone know how to decode this into an actual part number I can look up?

What cooling do you have by the way? Memory?

I've got a 7450 too.
Rock solid at 800 mhz with VCore 1.59.
If you get a lot of lockups, causes to look for before changing VCore:

1. Memory

I had loads of lockup-problems with Linux, disappeared with a change of memory.

2. Cooling

Try running at 600 mhz a while, if you get a more stable system, then it seems to be a cooling problem
