I happen to have an extra stick of 256DDR 3200.  I have the cheaper version of the G5(single 1.6GHz) that uses DDR 2700.  Would the stick of 3200 work in the mac, and just run at 2700? or would it just not work at all?

RAM goes backward. That is, if your slot is at 2700 it can run 2700 and lower. So, no.

I remember the good 'ol days of a year and a half ago when SDRAM was around and you could do that. got some PC133? stick it in your PC66 or PC100 system.

oh, and the names meant something back then. that RAM is not on a 3200MHz bus. glad they marginalized something else, turning it into JAMP... Just Another Marketing Ploy

I don't know about a mac, but on a PC the answer is certainly yes. The mobo will run it as fast as it can.

RAM ratings are like CPU ratings, its a maximum speed, they don't have to run at that speed.

actually, does my mac mobo only support 2700?  Are the mb's in the different g5's actually different?  On mine, there are only four ram slots but you can see the pin holes where the other four slots go, I just do not have them.
