Hi Guys,

Is it true that my 4/5 year old PPC G5 Dual 2.5 can actually have 16GB of ram and not the 8 Gb that i thought (and that Crucial Memory say is the max). I hear there are 2Gb sticks that can go into all 4 banks of 2?????

Cheers guys!

Dylan

The Quad G5 can access 16GBs, but the Dual can only access 8GBs. Now I have seen chat forums saying otherwise, and a couple of less reputable RAM resellers also claiming you can have 16GBs, but I have yet to see anyone actually claim they have 16GBs of RAM in their dual G5.

Quite honestly I would trust Crucial.

Let's know how you go? There is a difference between being capable of fitting it and what the processor can actually see.

This goes all the way back to Sawtooth G4's with 2GB memory using classic. OS 9 could only access 1.5GB and that is what the System Profiler showed.
