Question regards adding memory

[jbarley]

Ok for starters just pretend I'm referring to a PPC mac. I say this because this forum is where all my knowledgeable friends hang out, and anywhere else the most help you'll get is a rude suggestion to buy a new computer.
My Mac Pro 1,1 as delivered reported 4GB ram total, 2GB modules in slots B1 and B2, but in fact there were 3 2GB ram modules the odd one in slot B3.
I've added 2 more 2GB modules in slots A1 and A2, and also removed the 3rd module from slot B3.
Now my system correctly reports 8GB total.
My question is...
What can I do with the single 2GB leftover module?
I think the answer will be to purchase another similar module and install the pair, really just looking for some confirmation on this.
BTW this MP1,1 is a really sweet machine, I just love the modular design, the way HDD's just plug in like drawers, and just how almost silent it is when running.

Yeah it needs to be paired. This was posted in another thread:

They do need to be installed in pairs of equal size, but as I understand it sometimes pairs from different manufacturers work and sometimes they don't.
If you can get a very cheap stick of the same size but a different manufacturer, it might be worth the gamble, but otherwise I personally would use matched pairs.
Can anyone else clarify / give more details?
