Need help overclocking Ryzen 1800X

[ysfm17]

Motherboard : gigabyte ax370 gaming k7
Bios : Latest F31
Ram: G.skill F4-3200C14D-32GTZ ( XMP Enabled )
GPU : Vega 64
PSU: 750w corsair


I was trying to overclock my Ryzen 1800X to 4 GHZ.
after I read Gigabyte help manual :
https://view.joomag.com/gigabyte-am4-overclocking-guide/0517370001491902144?short

Also Reading and seeing videos about over clocking

So what I did
setting CPU Vcore 1.42000 ( I started with 1.38100 )
VCore Soc: 1.32000

CPU VDD18 ( Auto or 2.0 manual )
CPU VDDP ( Auto Gigabyte reccomndation +0.2 )

CPU Vcore Leadline Calibration ( High or Turbo )
VAXG Leadline Calibration ( High or Turbo )

Stress Test using ( RealBench )

Fan manual control to load 100% when reach 70c

so the maximum time on stress test I could get almost 40 minutes before the system crash.

I did not wanna go higher in voltage cuz temperature started to reach 85 in the stress test
but the average temp in this test 74-79

so are these numbers are normal as temps during the stress test?
and what shall I do to make the computer stable?

I use the computer for normal daily usage and Gaming

i dont think you should be settin soc higher than 1.2. its been a long time but this can cause problems being higher.

Pushing that hard for 100mhz doesn't make any sense, I would back it down to 3.9 all core and be happy.
Have you tuned the memory?
As above 1.2 etc, I use 1.1/1.15 Soc and Vcore 1.35/1.38 all core @3.9 on 2 machines.. performance gain for me came via tighter ram timmings which you should be able to get with F31, give DRAM-Calculator-for-Ryzen-1.5.0.5 a try. I would save your board and throw a 3700 or 3800x in when they are released!
I assume you are playing at 1440p anyway ? if not why not....

As above, aim for a lower overclock and make sure your memory speed is as good as the IMC will allow / timings are spot on.

I don't know the exact figures but 4ghz wasn't a guarantee on these.

Also worth noting when you are finding the CPUs limit, set your ram to 2133 or something low to take it out of the equation.
