I'm thinking that you'll have to overclock the CPU a bit and by a bit I mean to go from 3.4ghz to 3.8ghz which will require only a multiplier change or BCLK change and no voltage needs to be added. That CPU is capable of that clock increase without adding voltage, plus if you do the BCLK increase you'll be raising the ram MHz anyways.

Here's what you can do to try;
You have said that the ram will run at 1866mhz so set it at that, then the BCLK is currently at 100 so take and increase that to 101, it's only one step and once you do that look at the ram speed and see if it changed from the 1866. If it did then you can now save and restart to see if it will now run at the MHz that it showed.
Now if it's able to now run at above the...
If it's resetting then it's not getting the correct voltage, I have seen it go both ways where it's either too little or too much and it will cause a reset of the part your trying to overclock. I'm not going to suggest to increase the voltage because I'm not all that sure what's causing this problem. The issue can be settings, voltage or a defective bios. I've had a defective bios chip affect the Pci-e slots and the sata ports at the same time.
So at this point I'm going to lean towards it being a bios problem and don't rule out a defective bios chip along with a corrupted bios.
 
Is it possible to take screenshots of BIOS?
If not, I can take pictures of the settings for you with my camera, which settings do you want to check?

Edit: BTW By resetting I mean the PC restarts 2-3 times and the settings change back to Motherboard factory defaults.
 
So here are my settings:

I use the XMP Profile:

Then save and exit...
After restart, PC freezes for seconds and everything resets:

I set them manually:

Even the timings:

Save and exit...
PC restarts for a couple of times and everything resets:

I think you already know but this modules are not int the QVL, but that doesn't mean I can't use them right, and I know I may end up sacrificing voltage or speed, no problem but I want to get as much as I possibly can.

If it did then you can now save and restart to see if it will now run at the MHz that it showed.
Now if it's able to now run at above the 1866mhz then that shows you that you need to raise the BCLK and the good news is that you only have to go from 1866 to 2000 which is not a big jump and may only take a 102 or 103 BCLK to get there.

Even if you don't want to do this overclock you really are not far from the 2000mhz so running at 1866mhz is not all that bad. I know that your going to say that you bought 2000mhz ram and you want it to run at that but to get there your going to have to overclock something because that's what the motherboard says when it shows the supported ram speeds and next to the speed is (OC).

I've tried the BCLK change before and it handled 2000Mhz but that's a 107.2 BCLK!
I'm cool with changing the cpu multiplier but not the BCLK, because it also changes the GPU clock right?
Actually I'm currently running the cpu @4.5 1.15v. But only with the multiplier (x0.45) but I still can't go above 1866. Is there something else I should do?
 
The BCLK doesn't change the GPU clock. It changes the CPU clock so lower the multiplier and run the BCLK at the 107.2 and then decide if you want to clock the CPU any higher by changing the multiplier.
To change the GPU clock you have to use the program that is associated with the video card that you have, a program like MSI'S Afterburner is what's used for that.
 


But I've read that it'll change the hole motherboard clock:

That means if you increase base clock you increase both memory and CPU frequencies, you also increase the iGPU’s frequency as well. However with Ivy Bridge you shouldn’t be increasing the Base Clock for Air/H2O overclocking as BCLK OC takes a toll on everything on the PCI-E bus including your GPUs and your SSD/HDDs, so it is pretty much reserved for benching with colder temperatures. Don’t worry about increasing BCLK for memory speeds as there are enough memory multipliers with Ivy bridge/Z77 so you can always find the speed you want unlike with Sandy Bridge. However you can increase the BCLK slightly for high memory OCes where certain multipliers are better than others.

The base clock is usually left at 100mhz with the Sandy Bridge K, because the base clock affects the operation of the entire motherboard and increasing it will lead to instability.

You are right. LGA 2011 does not automatically overclock everything like LGA 1155 does. My mistake. I knew anything over about 105 could be dangerous to Sandy and Ivy and forgot Intel allowed for it in SB-E. I

The IMC in your chip may be able to get to 1866 at best.
It was designed to do 1600 with 1.5 volt ram sticks.
My Sandy Bridge I5 2500K will run overclocked at 5.2 stable but I have never been able to get above 1600 with my ram and I tried with 3 different RAM kits.
