Gigabyte Z390 Aurus Elite / What XMP compatible ram to buy ?

[Matteoking4]

Hi Guys,

 

I have recently rebuild my PC. 

I am having difficulties overclocking the i9 9900K paired with the Gigabyte Z390 Aurus.

The current RAM I have is Corsair vengeance 2666mhz CAS-16.

 

I am running 5ghz on all cores with avx 5 offset on 1.365 volts with XMP dissabled. (2133mhz currently)

System is stable-ish.

With XMP enabled I get nowhere...

 

I was wondering If new ram can increase system stability and if so what ram would be a good choice.

Looking for assurance with XMP-compatibility.

 

Kr,
