Can you help?...I've just ordered some more memory for my G5 (Dual 1.8 Ghz PowerPC) but it doesn't seem to fit properly. Wondering if I've ordered the wrong DIMMs. I ordered 1GB DDR400 PC3200 2 X 512 DIMMS-GEN. Are these compatible with my G5? They fit into the slots but stick out more than the 128s that are already in and so I can't get the ejector clips to clip back around them. Thanks if you can help.
