Ram for G5 1.8ghz

I just put 2 sticks of 512mb in my g5 with these specs pc3200r-30330, the machine doesn't recognize them. I notice that the existing ram got this on the label pc3200u-30330. Pease someone tell me the difference between these 2.

You need unbuffered Ram in a G5, unless it's a XServe
Fold with our MacRumors folding@home team and I dare you to fold with us and catch up with me if you can! Also, we have our own folding widget

We don't know what brand or model you put in, but

R = Registered or Buffered (usually seen only in Error Correcting (ECC) RAM
U = Unbuffered or standard RAM (Could be ECC or non-ECC, although Non-ECC is standard for almost all desktop and consumer machines)

Count the number of RAM chips on the module. If it is a multiple of 8, then it is non-ECC.

But if it is a multiple of 9, then it is ECC RAM and not appropriate for your Mac. If it says Reg. or Buffered anywhere on the label, it is also not for the Mac.

Ex = former, no longer. Spurt = a leak, esp. when caused by water pressure. Expert = a has-been drip under pressure.
