DDR3 ram prevents my PC from rebooting? What to do?

First thread yeah!

I have quite a big problem. I just built a new rig, these are the specs btw:

MB: Asus Rampage IV Extreme X79
CPU: Intel Core i7 3820, s2011, 3,6GHz
GPU: Asus GTX690-4GD5
PSU: Thermaltake Toughpower Grand 1200w
MEM: Crucial Ballistix Tactical Tracer 16 GB
4x4 GB - DIMM 240-pins - DDR3 - 1866 MHz / PC3-14900 -
CL9 - 1.5 V

And the problem is that I can't reboot. Every time I reboot my PC it totally doesn't do anything (after shutting down) what it does do is give me an error code 65 on my motherboard (RAM not found?) and the MOBO speaker (which will be taken away later) gives me LONG-SHORT-SHORT beeps. It happens at about 75% of the reboots, so about 1 in 4 it does actually work. Turning on works 100% of the time.

I do know that my memory isn't on the official RAM QVL. However I thought that shouldn't really matter.

I didn't change any bios setting which have to do with memory (or CPU for that matter) but the problem was from the start anyway.
I do know my memory can do 1866 while my CPU can only do 1600. But I thought that shouldn't be a problem. Also my motherboard supports extra memory power input via an EZ plug, that is there I think for OC'ing the ram, and I did try to connect that, but that doesn't help at all. I hope there is something in the bios that I can change to fix this? I have no experience with overclocking anything (yet) so please treat me as a noob.

I really hope the answer isn't buy new ram because I happen to friggin love this ram because of the LEDs.

BTW I'm dutch so feel free to correct any spelling mistakes.

I wish I could test it already but my first 1TB backup is currently copying so I'll get back to you. Thanks for the help! I hope it's not the MB because I really don't feel like replacing that..

Wow this is getting stranger with the minutes..
I changed it to 1600, which also changed something else, I screenshotted it (yes my bios has a screenshot function woohoo) so you can check it out:

After changing only the mem freq:

As you can see, something in the CPU changed with the underclock (all cores forced?) but as I have never overclocked, I have no idea what that meant.

However anyway, I restarted from bios 3 times, it worked twice, but 3th time back to error.

Then when I actually let it boot up, I got an error (just before windows) saying something like:

"overclock failed, press f1 to go back and change your settings."

I think I can conclude my MB fails here, right? As I can't even underclock my memory without failing? This really sucks..

BTW I do have the latest bios.

Wow Asus Costumer is a big disappointment. I contacted them. What they mailed back was basically this: here's our QVL: check if your memory is on there. If it isn't, you should buy memory that IS on there. (they wouldn't even check it for me)
Very disappointing. Guess I will never ever reboot my pc..
(I didn't do the memory takeout yet as I will have to take off my CPU heatsink for that)

FYI the latest bios update (2105) fixed all problems.
