Ugh, Memory Issues

Okay so first of all, I have the MSI Neo2 Platinum s939 Mobo that I think is causing this issue. The RAM I am using with it is Corsair 3200XL TwinX modules (2 512MB sticks for a total of 1GB). Keep in mind this is a first time system, none of the parts are recycled (except video card, but that is not the problem here). There are 4 RAM slots on this board, and 3 combonations will work to give Dual Channel capabilities. These are the combonations: Slot 1 & 2, Slot 3 & 4, or all slots filled. For the first boot, I tried having my RAM in slot 1 & 2. I got long repeating error beeps, and took 1 of the modules out, leaving 1 stick of 512MB in slot 1, and then the system booted up fine. To make a long story short, I have tried absolutely EVERY combonation to have it boot with dual channel, and it does not. Neither module works in slots 2 & 4, but they both work fine in slots 1 & 3. ATM I have slots 1 & 3 filled with both sticks, and the system powers up fine. Does this mean slots 2 & 4 are bad and I should get a RMA on this board? I'm stuck. Thanks for the help. For reference, here are the combonations that work and do not work:

(I tried both modules for all these combonations)
Slots,
1&2=No
3&4=No
1=Yes
2=No
3=Yes
4=No
1&3=Yes

Update:
I just noticed that when in slots 1 & 3, the RAM Frequency is 166MHz not 200MHz like it's supposed to be. When either stick is in slot 1 or 3 by itself, then they run at 200MHz. This leads me to believe it's a motherboard issue, not RAM. Hmmm

Try raising vDIMM, a lot of performance modules need that just to run at stock speed with certain boards.

- Using latest motherboard BIOS?

- For test, boot up with one memory module and set memory timings (tCL-tRCD-tRP-tRAS) to 2-3-2-10; Memory Voltage = 2.8V; 1T/2T Memory Timing = 2T; Max MemClock = 166. Save BIOS and shutdown. Put the memory modules in 1&2 and give it another go. Report back the results.

I flashed the BIOS from 1.1 ---> 1.3 and that did the trick. Works like a charm now
