[QUOTE="rexk, post: 1384042, member: 243284"] If by riser card, you both mean the two cards that are each holding 4 2GB sticks of memory, then how could one of them be bad if, when I switch their positions from slot A to slot B and then back again, they each have a turn at showing up and functional (while in B), while the other shows empty while in A.? However, it is logical that the top (A) slot that the card slips into may be bad in some way, because that is what consistently shows empty in About This Mac. I ran the hardware test again with the same result, except that under test results/memory, I noticed that at the top, it reports only 8GB memory, then proceeds to list 8 risers with 2 GB memory each, all showing functional. The logic board also passed the memory test, which reported no problems found at all. I just figured out the Terminal system profiler command, which reports only 8GB RAM and under diagnostics states that Power On Self Test failed on memory for all four DIMMs in riser A. However, if I switch the cards, the one that failed here will show as good when in the B slot. The Diagnostics also reports that the Hardware Test passed. [/QUOTE]
