Need help overclocking my laptop ram

Hello community! Newbie ram overclocker here. Looking for some help on pushing the ram further.

I bought an msi gt83vr-6re titan sli laptop. It came with 2 x 8gb sticks of 2133mhz ddr4 kingston value ram. I opted to upgrade to 4 x 8gb sticks of Hyperx Impact 2400mhz cl14 ram(xmp profile). Ram installed, everything is good.

In case it matters, Here are my laptop specs:
i7-6820hk 2.7ghz base/3.6ghz turbo- Overclocked to 4.2ghz stable
2 x gtx 1070 with out overclock
32gb ram

Decided I want to run at as high of a frequency as possible with a low CL. I went into the bios, set up a custom profile for the ram using the xmp profile settings as a baseline. I increased the memory ratio by 1, from 9 to 10. Reference clock=133. Ram booted @ 2667, sweet. I enabled the Qclk dram odd ratio as well for an extra 133mhz. It booted and the ram is sitting at 2800mhz @ cl14 @ 1.20 voltage(stock). It has been stable so far and benchmarks reflected at a 16% increase over my 2400mhz benchmarks.

I'd like to take it one more step further and run at a base 2933mhz + 133mhz qclk dram odd ratio for a total of 3066. I tried to keep the same settings/voltage and just increase the memory ratio from 10 to 11 but it blue screened on boot. I also tried to bump up the voltage from 1.2 to 1.25 but it blue screened again. Is this not enough voltage? Where do I go from here? Am I supposed to loosen up my timings by going from 14/14/14/35 to 15/15/15/35 + increase voltage? Is it even possible for the ram to overclock as high as I want it to? I called MSI and they stated the frequency limit for my model laptop is 2400mhz for the ram. That's already been discredited as i'm currently at 2800mhz on the ram. Not sure what to think or do. Please help

Ok so my bios shows the option to change the voltage for the ram but the voltage change doesn't stick. I go back into the bios and it is still listed as 1.20v. Any idea why it is doing this? Is there something else I need to enable?
I didn't see this post. Yes, you need to increase both DRAM + System Agent voltage to get even higher overclocks.
Also, your laptop might support up to 3200MHz, it doesn't mean your RAM does too. You overclocked an already overclocked RAM (XMP).

Overclocking your CPU cache can give a benefit too as some people just OC the cores.

The absolute max safe voltage limit by Intel is 1.5v but most overclockers go up to 1.30-1.35v.

There's a chance you might have reached the limit of your chip regarding frequency. You should try tightening the primary numbers or overvolt again.
BASIC RAM OC guide:
1. Set the voltage.
2. Increase frequency till you crash
3. Tighten the timings till you crash again
------------------------------------------------------------
There's also a basic formula for RAM.
CL/Frequency=Latency
14/2933 = 0.00477
15/3066 = 0.00482 (very small increase is acceptable)
16/3066 = 0.00521 You should avoid this

I'm going to boot up at 2667, increase the voltage to 1.35 and then adjust the memory ratio to 11 with the CL14 timings to see if it will be stable at 2933. If it is, then i'll be greedy and try to enable the QCLK dram odd ration for an extra 133hz. If it isn't stable, I assume 2800mhz is the highest frequency I can run @ CL 14 and then i'll try shooting for CL15. Just waiting for starwars battlefront 2 to finish downloading and then i'll commence. I'll update you guys with the results. Your help is much appreciated. THank you

I ended up figuring out to increase my system agent by 100mv with 133 ref clock/memory timing ratio 11/CL 15 - CR2 and was able to achieve 2933mhz overclock @ .00468 latency in aida64. Can't seem to get the full 3200mhz that skylake laptops can go up to but i guess ocing to 2933mhz from xmp 2400mhz was a nice yield on the memory. thanks for the help guys
