PC3200u-30330 or PC3200u-25440?

Is there a difference between PC3200u-30330 and PC3200u-25440? Just upgraded the ram in my G5 dual 1.8 Tower mac with some Hynix memory and wasnt sure if there was a speed difference as they are working fine with the mac just displaying different last numbers.

Macbook Pro, Mac OS X (10.6.4)

Hello Makman8688, and a warm welcome to the forums! 🙂

Those last numbers are the CAS rating...

Though I think they're still all going to be working at the same rate the OS chooses.
