LGA 2011 Weirdness

[_Drive]

Heyo

 

So I bought this Chinese mini ITX X99 board for a project I'm working on, and it claims to have an LGA 2011-3 socket (see attached image). However, all the googleing I can find says that those cutouts in the pin array are exclusive to Sandy Bridge and Ivy Bridge EP CPU's, which are the LGA 2011 socket, not LGA 2011-3. But, I bought an i7 3930k CPU for it, just to see if a LGA 2011 socketed CPU would work (It's a Sandy Bridge), but no, the keys are different. As they should be if it was a true LGA 2011-3 socket. But LGA 2011-3 socket CPU's don't have the pin cutouts, as far as I can tell. See attached images to look at what I'm talking about. The first one is the "LGA 2011-3 Socket," the second is the i7 I have, and the third is an actual 2011-3 chip (a Xeon E5-2530 V4)

 

Bottom line, I need help figuring out what exactly I have and what I can do about it.

It markets itself as "X99", use LGA 2011-3 CPUs in it. It doesnt matter what it looks like to you, you probably wont even find X99 chipset physically on the board to begin with (I've seen "X79" boards with z77 :P)

What DIMM slots are on the motherboard? If those are keyed for DDR4, the only possible CPU's that can work with it are LGA-2011v3 chips, or Haswell-EX/Broadwell-EX chips, all using the later sockets.

Sure, the socket is LGA2011, but it doesn't matter as the extra pins are for multi-socket boards.

My only LGA 2011-3 chip is a Xeon one that seems to want a C612 chipset, so it may take a hot minute to try that.

The DIMMs are DDR4 keyed. You sure those pins won’t do weird stuff with the cpu? Even on single socket LGA 2011-3 boards the pins don’t have the cutouts
