G5 RAM upgrade

Did the ram fit, did it not fit? Is it installed but does not show up in your operating system? Is it installed in the proper slots?

If you have a Dual Core, Single Processor G5, you bought the right ram. If you have a Dual Processor, Single Core (per processor) 2.0 G5, you need DDR, not DDR2.

The Late 2005 is the only model that uses DDR2. Verify that you have this model and get back to us!

 

Your Mac needs at least DDR2 533 MHz memory (aka PC2 4200), you've bought 400 MHz one (aka PC2 3200).
Exchange it for the right one.

 

Yes, this will be OK. Maybe consider 2GB sticks, depending on your needs OFC - but there's never too much of RAM

 

Your computer will read it as PC-3200 not PC-4200, imo. I have those in mine. Look for DDR2 PC-4200, they are 533MHz...

 

DC can't run PC3200 RAM so IMO it's only false ASP reading, it shouldn't affect performance.

 

Yes, that is what I meant. It still works but on system profiler it says PC-3200... lol.
