Hey guys, I recently upgraded my RAM to 16GB on my G5 powermac. I thought I would run the hardware test to double check everything is all good (I checked in activity monitor etc. and everything was fine, it read the 16 GB.) Now 4 hours into the hardware test (3 hours and forty minutes testing the RAM) I'm starting to wonder whether my machine is having some trouble. It says 'it should take 30 - 45 minutes or longer depending on how much RAM there is installed on the computer.' So if anyone has any advice or can tell me whether it usually takes this long on a G5 powermac with 16GB of RAM that would really help! Cheers!
