i have a G5 1.8 dual proc. and i have a friend who is selling DDR2 ram for a G5. in my system profiler it says i have just DDR, will DDR2 ram work also? can i run DDR2 and DDR together?
No, DDR2 will not work. It's possible that he has a newer G5 Mac model that uses the DDR2 memory. Just like my iMac G5 2.0 GHz, your G5 will only take DDR memory.
www.crucial.com has a really good ram finder. Just select your manufacture, product line and model and it gives you all the details for the ram you need....
