Anybody familiar with LGA 1366 pinout?

I'm trying to troubleshoot a motherboard with a DIMM slot that won't see memory.

I noticed a few pins that are slightly off in the socket driving the affected slot:

I found the intel socket specifications but was a little unclear on how to identify the name of each pin. Then I found this:

With the help of Paint for a flip and rotate to orient the image to match mine I think the pin on the left in my image is VDDQ and the pin on the right is "reserved".

Any educated opinions on whether this would cause a DIMM to not work? I'm not sure how they managed to get that way even under a magnifying glass they don't appear to be too mangled they're more at a slightly different angle vs the rest so they reflect light differently (easy to photograph, hard to fix if it's actually bad). I noticed after reseating the CPU & trying again that I developed another pin (elsewhere in the socket) with a similar look. At this point I'm relatively confident I didn't do anything horrible to mangle the socket but I don't have any better explanation as to why the DIMM isn't working.

I guess my specific questions would be:

1) Can anyone identify those pins by name? This is the document I was trying to use:

2) With a name are those pins likely to prevent a DIMM from working?
3) What are the odds I'll be able to RMA this?

And the answer is yes, those two pins will nuke DIMM 2. Some creative work with a pair of very fine tweezers and I now have 24 GB of RAM as expected.

Now on to the next problem... WTF is the default login & password for the IPMI on this board? You would think that would be relevant information that should make its way into a user manual.
