Hey, relative new to overclocking, just wanted some feedback

First of all Specs:
MoBo: Gigabyte Z370 HD3P
CPU: i7-8700K
CPUCooling: Noctua nh-d15
RAM: 2x 8gb Trident Z RGB
PSU: Corsair CX600M
Case: Aerocool Xpredator II with 2 Fans on top (pull), 2 in front (pull), 1 at back (push)
GPU: ASUS ROG STRIX 1060 6Gb

Cpu currently clocked at 5Ghz with 1.355VCore; XMP enabled(3000MHz);BCLK 100MHz; LLC on Auto; AVX Offset 0; Enhanced Multi-Core Disabled; Uncore Ratio Auto;

(Dont know if its important: internal graphics enabled and two relative old monitors are connected to CPU(DVI & VGA), third one is connected to GPU (HDMI))

Following is disabled aswell:
-Flex Ratio Override
-Intel Turbo Boost
-Intel Speed Shift
-CPU Enhanced Halt
-C-States C1 to C10
-Ring to Core offset
-EIST
-Race to Halt
-Energy Efficient Turbo
-Voltage Optimazation

Used Monitoring Software
CoreTemp
CPU-Z
HWMonitor

Prime 95 Version 26.6 SmallFFT: running stable for an hour now(not tested overnight yet, need to do)
Temps +/- 70°C, not getting higher than 75°C

Prime95 Vers 29.4: Cpu seems not to run stable. Cores dropping on Load, probably beacause their not getting the full1.355V, CPUZ sais Cores getting 1.2-ish, even though set on 1.355, LLC seems nothing to do for it (set on Auto, set on Turbo would probably change, need to test that)
Temps are due to Cores dropping Load not higher than 60°C

Cinebench: tested about 10 times, 1450 (something was probably running in background) to 1550 cb, (is that any good, not pretty sure)
Temps +/-69°C, not higher than 72°C, here again taking 1.2VCore flat, not set 1.355VCore

AIDA64: CPU, FPU, cache and system memory stressed, seems stable no throttling (tested for about an hour)
Temps pretty fluctuating from 50 to 79°C , but only spikes for a sec to 75+(such fluctuation normal?), VCore at about 1.2 to 1.23, again not set 1.355VCore

In general no crashes, BSODs or anything like that

Any opinion/feedback?
Improvements?
Something I should change?

Thanks in advance :)

Well I can only say that is a very good overclock and your temps are great especially for the small FFT test on Prime95 v26.6...Mine were a lot higher and I wen the delid route...I would not worry on Prime95 versions above 26.6.

Cinebench at 1550 CB is about right for the overclock...

I eventually settled at a vcore of 1.278v for a 24/7 4.9GHz overclock on adaptive/offset mode and I needed just over 1.325v for 5GHz though I had occasional spikes to 1.329v...

Overall, a really nice overclock..
