By the way, now that I read again, lags could be caused by entirely other things than RAM.
E.g. my M2 SSD was overheating under the 1080 Ti and needed relocation before system freezes went away.

I suggest you describe more in detail what is going on and fill out your full config so that folks can help.

all of a sudden I have a sudden cpu spike that results in a lag in the game

Okay, so that will be the slots A1 and C1.



I have Corsair vengeance and they work fine in.

run prime 95 at memory and controler test , if you hv any failure you unstable.

Almost all mb rog serial hv issue at uefi with RTL IOL training what make unstable anyting after 2400 mhz , if you cannot fix any settings at RTL IOL , you hv bug. Contact asus support and push them to fix this bug . Or make RMA.

all who say's they stable , they no make deep test memory and they use unstable system . I was try with many memory my omega its make unstable all what i put to them even QVL memory what most work 1000%

i write them to support about this issue , it's first reason why people make RMA .

Remember first always make support request to asus then ask at forum , you pay for support when buy anyting from asus. And ignore if they say about QVL , its lie , its too not work!
