First Time Intel Overclocker Help!!!

[JPStone]

Picked myself up an 8700K and a Gigabyte Z390 UD MoBo. I have only ever OCd Ryzen before so Intel I have come to learn is kinda a whole new game. I have gotten my 8700K to 4.6 GHz all core stable but all these odd settings like Uncore and C states and all that have me confused. I tried to follow a guide that all but guaranteed 5.0 GHz and that was a bust. I am at 4.6 GHz buy just setting the multiplier to 46 and bumping the voltage to 1.31V and maybe got lucky.

 

I am wondering is the limiting factor here my chip or maybe the MoBo? The motherboard is missing some overclocking features like VCore LLC control (it only has internal LLC settings) no BCLK adjustments. Also the guide recommended I disable VT-d, Intel Speed Shift, and all of the C state support but doing that seems to make it less stable.  My current rig setup is as follows

 

8700K

Gigabyte Z390 UD

Kraken X62 AIO CPU cooler

32GB GSkill Royal CL16 3200

GTX 1080 on open loop cooler

850W Corsair 80+ Gold PSU

 

Any suggestion tip, advice or anything else would be much obliged as I venture to try and hit 5 GHz on this chip.

Get a better board even if it means cheaper stuff elsewhere

 

Ready software like HWinfo, prime95 and AIDA64 first.

disable VT-d

doesn't help nor hurt anything

Intel Speed Shift, and all of the C state support

makes CPU run full speed regardless, plainly wasting power. Good for benchmarks, no good for daily use

Uncore

Similar thing to Infinity fabric, but because Intel has better OC support you can manually adjust this, instead of tied to the memory frequency
