I have done the same testing with the 512MB sticks and with same result. The MB won't even POST with the good 2048MB Corsair Stick I have when it's installed in slot B1 by itself.
Here is my CPU-Z Validation.

I've been running my M2N32-SLI Deluxe with a Phenom II 945 for a lil while now.
It's been running on 4GB of Corsair (2*2048MB) PN:CM2X2048-6400C5 in DIMM Slots A1 and A2.
Recently one of the memory stick died and system wouldn't post so I ran it with only 2GB in DIMM slot A1 for a few days.

So this brought me to do a lil upgrade and went ahead and got me two kits of G.SKILL PN: F2-8500CL5D-4GBPK to bring the system to a total of 8GB with all mem slots populated. Had to do a couple tweaks in BIOS, nothing mayor. I'm running Windows 7 Ultima x64 by the way.

The thing is that I've always had a problem with this MB when trying to run memory in slots B1, or B2. Below are the different ways I've tried to get this thing going.

Single Slot Populated
A1: POST OK, Windows Boots and Runs OK.
B1: NO POST, NO BEEP CODES, NOTHING.
A2: POST OK, Windows Boots and Runs OK.
B2: NO POST, NO BEEP CODES, NOTHING.

Two Slots Populated
A1+B1: NO POST, NO BEEP CODES, NOTHING.
A2+B2: NO POST, NO BEEP CODES, NOTHING.
B1+B2: NO POST, NO BEEP CODES, NOTHING.
A1+A2: POST OK, Windows Boots and Runs OK.

I have not been able to get it working, ever. I'm just trying to figure out if anyone can shed some light into what might be the problem or if it's simply that my motherboard had CH_B DIMM slots dead. I've tried every possible way with just a stick in slot B1 for example to get it working and it will never POST. Resetting BIOS, presetting memory timmings and all that stuff, but I'm stuck with 4GB I guess unless anyone has any info/idea that can help me out.

Try pulling all the sticks and reset CMOS,install all 4 and reset CMOS again,see if that helps.
Or maybe try running memtest86+ with one ram stick in the B channel.(see if it is recognized by Memtest)
I have 2 M2N32's running 4x1gb(@800) and have never had to do any thing special for them to work,aside from setting volts and timing manually at first boot.
Good luck

I think the main thing is I have to get it working with just one memory stick in slot B1 or slot B2. I believe that CHB slots are completely dead. That the memory slots or the controller for those slots is not working properly. I'f I had a schematic of the board I could probably figure out what's the deal.
According to the M2N32-SLI Deluxe manual the board should work with just one memory stick in any of the slots, mine doesn't work if I have just one mem stick in slot B1 or in slot B2. I can't run memtest86+ because it won't boot from anything.
Just another question, could it be a video card problem?

Any Athlon II or a Phenom II up to an x4 945 will work out of the box(with bios update to 5001).

I have the BIOS updated to 1804 using the "ASUS Update V7.17.17 for Windows XP 32bit/XP 64bit/Vista 32bit/Vista 64bit/7 32bit/7 64bit" utility I got from the mother board's download site.
It seemingly exited out with an error. I don't remember which (had a few beers before working on that last saturday! ) When I tried to update to 5001 the utility screamed that the 5001 bios is older than the one installed...
I'll try and get a few screenshots to post here...
