256GB RAM on Asus ROG Zenith II Extreme Alpha issue?

[Oliveros]

Hello,

 

I bought corsair vengeance rgb pro 256gb 3200MHz along with ROG Zenith II Extreme Alpha and threadripper 3970X, I know that this 256GB corsair is not listed on the QVL list for this motherboard, but I had to buy it because the other RAMs were out of stock. do you think is it an issue? if it is not on the QVL?

 

I contacted Asus and they told me it is better to buy RAMs listed on the QVL; do you think is it really an issue?

Honestly sometimes I feel like adobe after effects is a bit slow to navigate into my timeline comparing to my alienware laptop with 32gb ram 2666mhz and i9-9900K and 2080

 

also when I turn on the [D.O.C.P] in AiTweaker to boost it to 3200Mhz windows sometimes get BOSD  

 

please any suggestion to my issue?

Sometimes I get also mem test at boot here's a video attached, I ran memory diagnostic tool and no issues, also memtest86 with no issues.
