will start with one ram module but not two

[nam2000]

I have a powerbook g4 running leapard 10.5.6
I recently upgraded the ram from 1 1g module to 2 2g modules. It will not start with both modules in at once (2g,2g) but it will start with one of the two in and the second port empty (which port is empty doesn't matter). When it has both in it beeps once and doesn't start. Any idea why this would happen and/or how to fix it?

thanks.

If you have one of the later models, you need 200-pin PC2-4200 DDR SDRAM SO-DIMM memory modules.
And the last PowerBook (G4, 1.67GHz) only supports a maximum of 2GB of RAM.

obviously, one of the RAM modules is faulty

Not really? The system only handles up to 2GB so placing 4GB in it won't make it run.
