GA-X58-UD3R Won't Enable 3rd DIMM Slot

[TrueFlog]

I built this new PC about three weeks ago, and yesterday I noticed that the BIOS won't enable my third DIMM. It recognizes that I've got RAM in the slot, but it doesn't count it toward the total memory.

Windows shows something similar.

I swapped the RAM sticks around, and the problem persists, so I know it's not a bad stick. I'm guessing it's a problem with the board or may be a BIOS setting. Also, I'm pretty sure this was working a few days ago. I've been tweaking the BIOS alot for overclocking - maybe I tweaked the wrong setting? Any help would be appreciated!

I took a look at the socket, and it's definitely got a bent pin or two. That makes sense 'cuz it worked for a few days, then quit right after I removed and reseated the CPU. Great, I've had it less than a month, and I've already bricked it...
