MSI Eclipse with 12gb ram only posting 8gb (and other issues)

Question

I have several  issues with  my eclipse motherboard, the first problem has to do with RAM Dimm slot's AO, A1.
PROBLEM 1
A little back story on the situation, earlier today i adjusted my green power genie to max power cooling - it down clocked the voltage for the ram and cpu. after i installed some security updates for windows 7 i powered off the PC. I turned my computer back on 30 minutes later, i noticed a weird bios error message "previous overclock has failed, please reset your setting to default". I then reset the CMOS on the motherboard to undo the previous settings. I booted the PC up for a second time, then noticed the post screen with my system specs, had my ram at 8GB when i had 12GB installed. I then went into the bios(1.b)and pressed F5 to view my Ram total. It showed four slots posting 2gb per dimm except A0, A1.
I went through the normal troubleshooting (removing the cards and HDD's, reseating ram in different dimm slots.. etc)
I remove all ram except one 2gb stick. i reinstalled  the 2gb stick in the black dimm a0 slot and booted the system. it will power on, stays on for a minute and half then power cycle(reboot over and over). i then tired 1GB stick in the A0 slot, same problem. The system with boot in the other two black slots (B0, C0). the same problem is with the blue A1 slot as well.
Could it be a bad board that i have? or is there something i'm missing.
PROBLEM 2
I have four cards that i want to use on my system, Two HD5770's in crossfire, my sound blaster XFI Fatl1ty Champion in the first (PCI-E x1 slot) and my TV tuner in the first PCI x8 slot. the problem is getting them all to work at the same time. if i install all of them together the system will not get past the black windows screen(it freezes). if i use a combination of the three, the system will boot up with no problem.
Anybody in the forums with an eclipse able to use four cards and crossfire at the same time?
Could i have a bad motherboard?
What is RMA? is it a replacement or repair?

Have you tested each of them individually? What are you setting the RAM speed & timings at? Unless your running Photoshop or similar heavy apps., 12G RAM is a negative IMHO.
nothing really heavy, but i do multi-task and have a lot of apps/ games/ benchmarking going on at once.  firefox uses a lot of ram on its own. i have around five sets of 3 (2 sets 6gb and 3 sets of 3gb) and none of them work in the a1, a0 dimm slots. the memory controller probably burned out. i dont see how that can happen as i dont overclock regularly.

Other thoughts. What is the current bios version?
- i updated to 1.11(1.b)

Does the board support 1.5G TB HDD's?
Yes - i believe so, the bio's recognize all 4.5tb

More voltage is needed more than likely to the CPU, QPI, RAM, IOH, & ICH or a combination thereof rather than using a utility that is trying to reduce it. You have a lot of stuff to power up.
  it only down clocked the cpu to core 0.00v/qpi 0.00v, PPL voltage  1.6v and memory to 1.65v , IOH to 1.02, ICH 1.35v

If this is a brand spanky new build, it may be best to establish a stable system in a bare bones configuration, & then add components making any note of any areas that may need a power boost or settings adjustment. To sum it up, CPU has developed a problem, RAM is faulty, board DIMM slots have become faulty, bent socket pins, voltage distribution is faulty or needs tweaking.
i have done most of your suggestions, but all of my test is pointing to a faulty motherboard. i mean the board has 7 pci slots of which 3 work when in crossfire. the x-fi sound card that came with the board came doa, so i should have been more cautious from the beginning and returned it to newegg then. now i am going to have to RMA the board and be without it for close to a month.  its frustrating
