Here's the motherboard test: occupy DIMM slots 1-3-5 and see if the memory is correctly reported. Do the same thing for slots 2-4-6.
Also, what kind of motherboard is this? P55/X58? Report back.
Sorry for the confusion.
(1) 6 DIMMs at 2GB each
(2) X58 UD5 rev. 1
(3) I did the combination last night and each time it was the C channel when both slots were occupied. The Gigabyte x58 UD 5 rev. 1 specifies the following:
1 DIMM = Slot 1, Channel 1
2 DIMM = Slot 1-3, Channel 1-2
3 DIMM = Slots 1-3-5 in channels 1-2-3
4 DIMM = Slots 1-2-3-4 in Channels 1-2
There are no other combinations that the board supports, according to the manual.
Last night I retested:
Slot 1, Channel 1 - 1 DIMM OK
Slot 1-3-5 Channel 1-2-3 OK
Slot 1-2-3-4 Channel 1-2 OK
All slots filled: Post counts 8GB RAM, BIOS reports 8 with Channel C not reporting. Windows reports 12GB installed, 8 Usable.
