I've got a PowerBook 540c that I'm having fits with. I have 3 different RAM cards for it: a 32mb card, a 32mb card, and an 8mb card. The 8mb card causes the machine to not POST, even preventing any sort of startup chime. The 2 32mb cards at least allow the machine to boot, and start the installed MacOS (7.5.3, ATM), but both produce "The built-in memory test has detected a problem." errors.
I've taken all the cards out, and checked the pins, but I don't see anything wrong. I also don't see anything wrong with the PPC upgrade card's pins.
I'll believe that one of the cards is dead, but not both, at the same time. Are there any known compatibility issues with 3rd party RAM cards and PPC upgrades for the 500 series? Does anyone have any other suggestions?
Thanks!
