I have ryzen 7 7800x3d and DDR5-6000 cl26 which is unstable .
I'm now in the testing time with Memtest5 from USB and I'm changing slowly settings not even to go in windows .

My question is, if that enough is to test main stability or will be still big surprises in windows with OCCT ?
That is my second step .

How was your experiences ?

On picture are old (expo) timings with cl28 because 26 was unstable .
I think that actual settings can be much much better .
