Hi,

So I have a dual 2.0Ghz PowerMac G5 with all PC3200U sticks of RAM. I found a good deal on more RAM to upgrade it with. All the specifications of the RAM are the same, but I noticed that it's labeled as PC3200 WITHOUT the 'U'. Does anyone know the difference? Not just that, but I want to know if this will work in a PowerMac G5, and if I can have both PC3200U sticks in the Mac, as well as PC3200U sticks. Thanks.

EDIT: I have found that the PowerMac G5 was actually shipped with PC3200. PC3200U obviously works in it, but I don't know about mixing and matching. I am putting in matched pairs for sure, but I am wondering if buffered vs. unbuffered RAM will have issues together. Mostly likely not, but you never know.

AFAIK 3200 and 3200U mean the exact same thing- they are both unbuffered. Some OEMs simply choose to highlight that fact by appending a U to the speed.
