Thanks for any clue! Hi! Sorry. This will not help you, but maybe you can use this information anyway. I once got two used DIMMs of SDRAM PC133 from a PC and wanted to use it in a Power Mac Quicksilver. The serial numbers printed on the chips showed that they where produced in sequence, and therefor they must have been bought together. They worked well in the PC. Now comes the riddle: How come, one worked in the Quicksilver and the other didn't? I swapped them around in the slots but nothing worked. Don't know why the one wasn't recognized at all, while the other worked well. Maybe you will have to accept the fact that the Power Macs are kind of picky when it comes to memory. If you buy used SDRAM it is always good that the seller guarantees the memory modules will work in a Power Mac. So you can return it and get your money back, like you would in this case. Regarding density: I've never been able to distinguish high density modules from low density ones. How can I? Is it written somewhere? And why the hell did my Mac take only one out of two _in squence_ produced DIMMs? Cheers, Andreas. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
