Hello, I would like some advice ASAP, if possible: I just purchased memory for my new G5 1.6 Ghz machine and was sent 400 Mhz PC 3200 memory (for the 1.8 / 2.0 GHz machines) instead of 333 Mhz PC 2700. I was about to send it back, but then realized that the faster memory might be compatible with my machine after all (which currently has 2 x 128 MB of 333 Mhz PC 2700 sticks in it). Is it compatible, and if so, are there any disadvantages to installing the faster RAM? Should I exchange it for PC 2700 or keep it? Thank you!
