Do you have another CPU you could try?Or borrow? Thats where I would go next.

Microcenter is VERY good with returns. Usually no questions asked. I would say try the 950,and take it back if no luck. For 200.00 it's a better CPU than the 920 IMO.

If you are sure the ram is working (all sticks), that  only leaves the board or the cpu. I saw in a previous post that you were thinking about trying a difrent CPU, How did that work for you, were this round of tests on the new CPU ? If you want to RMA the board that would be a option, if the new one didn't work you would know it was the CPU, but then again reseating it could fix it also, ( all the bord is is a series of sockets to put your ram in, traces to connect the ram to the cpu, ( which contains your memory controler), and a socket for the cpu to sit in. A poor conection at any of the sockets will show the same symptoms as a failed componant, a short at any of those connections will show bad as well.

if the heat sink is too tight, the motherboard will flex a little bit. Very hard to notice without a straight edge. The motherboard flexing may cause a few contacts not to mate/ie they work loose from the PCB, loosening the bracket makes them reconnect, thus flattening the boards profile.

theanimedude :  Go into the bios and select reset to defaults , save and exit / reboot , and note what the post sequence shows as per memory speed ( ie : 1333 or 1600mhz ) - as I see from your subsequent settings post that your memory speed is [1866mhz / 2:10] .  That suggests that the memory target speed is 1866mhz , while it should be 1333mhz (with your current memory) or lower.  You should then also see a (2T) command rate , and Triple in the Eleet utility.

Do not go by what the BIOS is telling you on memory speed, BIOS relates everything to a stock clock, If you are running your clock at 133.3 stock, than a 2:10 is 10 X 133.3 or 1333. If however you have changed your clock you will need to adjust, I suspect the information posted on post # 22 is just wrong , a cut and past error, as there is no way to get 1866 memory with a 2:10, unless your running 190. clock speed. E-leet in post 12 is showing 1600, Because it's DDR, E-leet shows 1/2 your memory speed. There may be some confusion because of the pics, and changes you have made along the way.
I do suspect loosing the cooler will solve your issue, unless a pin got bent along the way. or the cooler frame is shorting a pin on the CPU.

yea sorry taht was a cut and paste error.
 
But its 1333mhz when it boots up
