If I OC past 3.6 my computer just restarts about 10 mins into Prime. 3.8 will restart, and 3.6 is perfectly fine (prime stable) and at stock volts. I feel like I'm making a silly mistake.

You might need to increase some voltages, Vtt/QPI and Vcore.

 

[cinfidel]

Vtt is at 1.34 and vcore is +1000mv

What does +1000mV correlate to your actual Vcore. Try CPU-Z for comparison.

Okay so I played around, and this is the most stable i can get it: 3.70ghz Vtt 1.34, stock vcore (more vcore is actually way less stable), 1.88 PLL. And this time i got an error, instead on a restart. It was 0x00...124 Ill check what i need to raise according to this error. EDIT: 124 means decrease/lower vtt, so I'm trying with 1.41

i thought 124 was Vcore as well. Vtt/QPI should be arouns ~1.4v for that OC because of the high Ram Speed.
What i would do is, put Ram multi to lowest. Stabilise the OC on the CPU. Then put Ram to stock 2000Mhz. Now you may need 1 or 2 notches more Vcore. And you will need QPI/Vtt adjustment.
Make sure Uncore is 2x the Multi of Ram. And QPI Multi is at the lowest (not slow mode though).

1.88v PLL is plenty. More of it can be worse off. Some find it better at 1.70v

What is the Vcore readout in CPUz?

 

[cinfidel]

Well I have it down to 6 hours stable with 3.70ghz, 1.41 vtt, and stock vcore.
