There's a PDF for the Drive Replacement, but not for the RAM replacement instructions. Do you know if or where there's a PDF for RAM replacement instructions?
Thanks Neil

For clarification, I'm still not sure if it matters which numbered DIMM slot the NEW Ram will be installed in?
It used to matter in older G5's that PAIRS of addtional RAM needed to be installed in MATCHING numbered DIMM slots.

and http://eshop.macsales.com/shop/memory/Mac-Pro-Memory#667-memory
667MHz ECC Mac Pro Memory Information
- 8 Total Slots, 32GB Supported
- Must Upgrade using Matched Pairs
- DDR2 240 Pin Fully-Buffered DIMM
- 72 Bit (64 bit + 8 bit ECC)
- Mac Pro Specific Heatsink on Module
- Four or More FB-DIMMs installed provides for best performance
FB DIMM technology takes advantage of multiple channel access. Apple recommends the use of 4 or more modules to take advantage of this 256-Bit Wide memory architecture. Modules must be installed in pairs, each module is 64 Bits Wide + 8 Bits for Error Correction (ECC).

Jun 11, 2014 5:43 PM in response to ENIGMACODEby Grant Bennet-Alder,The first page of the latest document Niel linked explains that for your Mac Pro, memory is installed in matched pairs in adjacent slots on the same Riser-card.
Largest DIMMs should be installed in the lowest-numbered slots on each riser-card.

I actually called OWC and they said to first remove the old RAM and relocate all 4 modules to the bottom card.
Then install the NEW RAM into the top card.
Thanx
Mike
