Hi all. I recently bought a G4 MDD dual 867 and I LOVE it. I am having just one issue with it though.. A couple hours after I got it I ran the Apple Hardware Test on it and it found an issue with 1 of the 3x256 memory sticks. It simply said that it failed the test. The 2 hours before I used the hardware test I was running Tiger with no issues at all.. No kernel panics at all and none ever with it. I thought that was a sure sign of bad hardware? Is the ram ok or not? Anyway.. now and then the system just locks up on me. If I am playing music or a podcast when it happens it sounds like a record skipping over a 1 second part of a song over and over till I do a hard boot. Everything locks when it happens. The lock ups are too varied and different to easily trouble shoot the issue.. Other times it has happened was when I opened a video podcast in itunes and twice when I was using Google Earth. Any thoughts or ideas?
