8700K OC help

Hello,
I am very new to overclocking. I've been trying to OC my 8700K to 4.9GHz (can't even get to 4.7GHz) but was not successful. I was wondering if you could guide me or let me know if I am missing some settings.

My setup:
NZXT H200i case
Intel 8700K
Kraken X62 liquid cooler
Trident-Z 16GB (8GB x2) 3000MHz RAM
Corsair HX750i PSU
Asus Z370i mobo
hwinfo64 for temps
CPUZ for Vcore (cause hwinfo64 doesn't list vcore for some reason)

Attached are the UEFI settings and here are the voltages, multipliers, and LLCs I have tried that haven't worked:

Code:
Multiplier     ---     VCore    ---     LLC
49                        1.31              5
49                        1.32              5
49                        1.33              4
49                        1.33              5
49                        1.33              6
49                        1.34              4
49                        1.34              5
---------------------------------------
48                        1.32              6
48                        1.33              6
---------------------------------------
47                        1.31              6
47                        1.32              6
47                        1.33              6
with prime95 v 26.5, some combinations were able to pass first round of tests (10 tests per logical core) but as soon as the second round started, the computer either froze or BSOD'd. Temps also got to 99C when the second round started with voltages higher than 1.32v.

I honestly think prime is too heavy on the CPU. You could just test while gaming cpu bound games like pubg.

My primary goal is encoding really which prime95 closely resembles. In one of the scenarios where prime95 failed, I also tried my current encoding application (Hybrid) and temps got dangerously hot around 95C.
