@Raja:
I will be updating my post with BIOS settings. As I stated in my first post, this overclock and system components were in a Rampage Formula IV and perfectly stable with no random reboots. I have not tested at stock CPU frequency. But I can confirm essentially anything over 40x100 results in random reboots. They really are random, I played probably about 6 hours of AC4 Black Flag last night and no problems. Yet, this morning I found my system had rebooted itself for no reason.
I have also stress tested with GPUz and Heaven/Valley for several hours and no issues.
@Raja & @Praz: My memory kit is at stock settings 1866Mhz 8-9-9-24-2T 1.6V. Memory kit model # is F3-1866C8D-16GTX

If the reboots are still present with stock settings lower the memory speed to 1333MHz. Your memory is not qualified by G.Skill for the X79 platform and this could be an issue. I have 8 2x8GB sets of the 2400MHz TridentX. Any two sets work fine together on the X79 except one set. That set causes instability when used with any other set. Move to Z87 and the issues go away.

I think part of the issue here is for guys like you that have "upgraded" from the other board thinking all the settings and voltages needed are exactly the same. This board is tuned for Ivy-E primarily, so most of the auto parameters and deeper stuff we do is tailored for those CPUs. There are some changes to the poewr circuitry as well (DRAM voltage FETs are changed) - therefore diallied in OCs from other boards may not cross-correlate.
You need to list everything you are changing, how much voltage range you have tried etc. Try to be as complete as you can. My gut is telling me voltage/memory timing issue (similar to Praz above).

There are fewer users that use SNb-E with these newer boards than those that use Ivy-E.
The VCCSA scaling is Ivy-E related I suspect.
The voltages you are setting and what you get on both boards would need to be finely compared with a DMM to make sure it is the same. LLC between boards and circuits varies.
I think your Vcore at "1.76V" is a typo...
If it were me:
1) I would "underclock" the memory and see how that impacts things
2) I would not limit the voltage I use at this point too precisely - like I said board is designed around Ivy-E so you might have to make some concessions. Boards generally clock CPUs better if they were designed for thos CPUs from the ground up. Especially the case if tere are any DRAM trace layouts to suit a given IMC. Doubly so if the modules being sued were never intended for a platform.
3) You did not state if the voltage you are using is manual or offset.
At this point, it seems rather than have us help you, you'd like us to hand you some kind of UEFI that fixes all this for you. There is no chance of that whatsoever if we cannot get a complete picture of what is wrong (design variance between boards and given clock margins withstanding). This requires some kind of flexibility on your part.
