I read somewhere before that the DX58SO board will not boot with single DIMM in black slot, need to populate Blue channels first.
I am not using the black slot at all. The blue slots are DIMM 0 Channels A B and C.
This issue involoves only the blue slots.
I just purchased and installed the DX58SO (Ver. AAE29337-701, BIOS 4598) with the I7 920 and I am having the exact same problem. I am trying to use 3 sticks (2GB each-6GB total) of Kingston 1066 RAM (from the approved memory list) and can only get 2 sticks (4GB) to work. Like you, Channel C seems to have a problem, but A and B have no issues. I've tested all three sticks individually in channel A and my PC started up without any issues. So I don't think my RAM is the issue. Were you able to find a solution? Please help!
I am having similas issue, motherboard was working with tripple channel for a few months and now it works only with 2. Did you resolve the problem?

I have similar problem with my DX58SO -> Channel B stop working (The blue slot in the center of the 2 others blue) This setup have 2.5 year old and working well but sudently computer power off itself and refuse to reboot (it boot, fan running,no beep code, screen stay black in stanby mode, no disk activity . When I remove the DIMM in B channel, computer boot perfectly. I have put new set of 3 DIMM and same thing happen if something in channel B computer not booting. So A, C, A+C ok but B, A+B, A+B+C, B+C fail.
I have resset the bios setting to default, but no change, have unplug computer for week-end... nothing change, I can use only A +/ C slot never the B.
