Okay I added in 2x1gb (RAMjets) sticks awhile back along with the Mac Pro's stock 1gb. What do I need to add to make it run optimally? If I go 4x do I just need 1 more 1gb stick? Or will I need 2x1gb? Also identical just means speed right? Or does it mean identical brand, heatsinks... the whole deal? Thanks.
Got a tip for us?

Can adding more memory slow down my Mac Pro?

Way too technical for me. Can someone just summarize the relevant points for us non-engineers.
This one is very clear to me: http://manuals.info.apple.com/en/MacPro_MemoryDIMM_DIY.pdf
The Intel one had me chasing my own tail. Or the author was chasing his own tail and I went in circles with him........
Please, let's come to a consensus! I'm in the same boat as a lot of people are or will be in.. Mac Pro ordered with 2x1GB stock configuration, what's the best upgrade map? Old Apple PDF or old Intel PDF page 294 - ???

Everything says the same thing, the only thing that is different is barefeats assertation that 2x2Gb and 2x1GB is somehow a bad choice. I think the only thing we really need is someone to benchmark 2x2GB+2x1GB vs 4x1GB or for Apple or Intel to respond to the matter.
2GB DIMMs are obviously the best investment, so I guess this is kind of an important topic. Honestly I would be very suprised if there were any real issue with having 2x2GB+2x1GB.
After debating myself to death, I'll be going OWC 2x2GB + 2x1GB Apple stock. 6GB sounds good enough to get started.

The last link states:
Mac Pro (Early 2008)
The FB DIMMs used in Mac Pro (Early 2008) computers are 800 MHz DDR2 ECC fully-buffered DIMMs. The Mac Pro (early 2008) has eight FB DIMM slots on two memory riser cards that support up to 32 GB of main memory. The DIMMs are installed as pairs of 1 GB, 2 GB and 4 GB sizes.

I don't understand why Apple ships the Mac Pro (early 2008 model) with one DIMM on the riser A, slot 1, and one DIMM on riser B, Slot 1. The DIMMS are on 2 different risers. Doesn't seem like a pair to me. Seems like a 1 and 1.
