well got new memory for my g5 and it boots and seems to be fine but I have a question. In system profile it shows memory speed as pc3200U-25440 what is the 25440 part?
because one of the 4 sticks does not have that number(dimm 2):
DIMM0/J11:

Size: 512 MB
Type: DDR SDRAM
Speed: PC3200U-25440

DIMM1/J12:

Size: 512 MB
Type: DDR SDRAM
Speed: PC3200U-25440

DIMM2/J13:

Size: 512 MB
Type: DDR SDRAM
Speed: PC3200U-30440

DIMM3/J14:

Size: 512 MB
Type: DDR SDRAM
Speed: PC3200U-25440


is this a problem?? I am freaking out...lol j/k
I just want to make sure it is ok to run it like this...wierd

I guess that number is the latency (CL).

From Crucial:
"CL stands for CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Low CAS latency at a given frequency is faster than high CAS latency at that same frequency. (For example, CAS2 is faster than CAS3.) However, lower CAS latency will NOT necessarily make your system faster. Your computer will only run as fast as the "slowest link" in your system, so you can't speed up your computer by adding memory that is faster than your current memory. The way to make your system faster is to add more megabytes (MB) of memory."

It appears you bought memory with different configurations. You should replace the slower module (the different one).

Just a note about that, yes, CAS speeds matter, but, for General use, you honestly would never know the difference. We are talking milliseconds of time savings here. For certain long term number crunching apps you would see some time savings, but for average day to day use, as long as it seems ok stick with it.
The time saved you would lose later as you sipped your coffee.
I would stick with what you have, and just add more, or look to remove other bottlenecks in your system if you have any.

I agree.
