I noticed about 2 weeks ago that my Mac Pro (early 2008) was reporting 1.5 GB instead of the 2 GB that I was sure it had. That made me angry 
(at myself mostly for not noticing earlier), but I had planned on buying more memory anyway so I went ahead and bought 8 GB (2 x 4GB) and replaced the two DIMMs in the computer. All seemed well until I started getting correctable ECC errors on one of the DIMMs. I reported this to the manufacturer and they suggested zapping the PRAM which I did. Now, my computer lovingly reports that it has 6 GB of RAM instead of 8 GB.
Oddly enough, this is the same pattern as before. One of the DIMMs is showing as a 2 GB rather than as a 4 GB DIMM. The computer runs fine but reports 6 GB of RAM. This is weird. Any clues?
