DDR4000 in a dual core 2.5GHz G5

[maniac330]

will replacing the DDR3200 in my Powermac G5 with DDR4000 give any noticable increase in performance?

System stats:
dual core 2.5 GHz processor
2.5ghz crucial ram
500GB WD HD
ATI 9600 video card
OSX Tiger 10.4

No, you won't have any speed up. The RAM speed is limited by the logic board, not the RAM itself. So if you put in the faster RAM it will just scale down to the same speed it is running now, DDR3200.

Nope - the Mac is driving this bus, not the RAM.

You know all those ads that a certain EBay seller puts on Mac RAM - Hyperformance, Optimum speed, Fastest possible RAM for your Mac?

All Bunkum. If the RAM is compatible with the machine, it runs at precisely the same speed as all other RAM that is compatible with the machine.

I read somewhere that the FSB on this system is supposed top be 1.25 ghz. DDR 3200 is 400 mhz. Is it on a seperate slower bus or something?
