The "Dell Dude"


Build:
Intel DX58SO w/ latest BIOS build (5600)
Intel Core i7 920 (Bloomfield)
2x Corsair XMS3 CMX8GX3M2A1600C9 v8.16 4GB DDR3 DIMMS (Herein known as "yellow") - bought eons ago and has been working fine
2x Corsair XMS3 CMX8GX3M2A1600C9 v3.19 4GB DDR3 DIMMS (aka "blue") - bought on eBay earlier this week
GeForce 8x00 GT of some fashion with 256MB onboard RAM
----
Both pairs are 9-9-9-24, both 1.65 volts, both 1600 MHz.

The DX58SO has 4 DIMM slots. 3 are blue, 1 is black.
Channel A DIMM 1 (black)
Channel A DIMM 0 (blue)
Channel B DIMM (blue)
Channel C DIMM (blue)

I have attempted all possible iterations of RAM pairings to get it to work. I'm currently running 1x Blue and 1x Yellow in Channels B/C. If anything goes into Channel A, I get 3 long beeps ("No memory"). I have also attempted to run 3x4GB and get the same error.

Some Intel rep posted:

Your processor is capable of supporting only 1, 2 & 4 GB DIMMs (to a maximum of 16GB); it cannot support 8GB DIMMs.
For optimal memory access performance, use three identical DIMMs in the (blue) Channel A DIMM0, Channel B and Channel C sockets.
If you add a DIMM in the (black) Channel A DIMM 1 socket, it must be identical to the DIMM in the (blue) Channel A DIMM 0 socket.
By 'identical', I mean same size, same voltage, same weight state configuration, etc. Optimally, you have purchased the four DIMMs as two matched-pairs (i.e. they are identical and have been tested together).
Adding a DIMM in the (black) Channel A DIMM 1 socket will indeed reduce memory access performance. In my opinion, the improvements in overall O/S performance as a result of having 16GB (instead of 12GB) of memory should easily offset the reduced memory access performance. I thus consider this upgrade to be a net win.

The only thing I have NOT done is remove the CPU and reinstall. Mostly because I have no idea where my Arctic Silver is anymore.

Any suggestions? Any experience with this devil board?

edit: After posting this I remembered that I'd read something about Intel XMP I have enabled it and booted fine with 2x DIMMs. Go to 4 or 3, still three beeps.
