Mac Pro 2008 memory upgrade, 1Rx8 and 2Rx8

Hi there!

I have bought two second hand (Apple original) 1GB memory modules from a 2008 Mac Pro identical to mine. The two original modules from my machine have the following specs:

1GB 1Rx8 PC2-6400F-555-11

The new ones:

1GB 2Rx8 PC2-6400F-555-11

Is the difference between 1Rx8 and 2Rx8 significant for installation and operation and what does it actually mean? All the modules are manufactured by Hynix.

2008 Mac Pro 8-core / 2008 MacBook Core 2 Duo, Mac OS X (10.5.8)
