Hi
If I enter primary timings manually PC is not stable, but same value auto timings working fine. I want to tight up the timings but I have this weird issue if I touch primary timings, even entering stock values. Doing overclocking for many many years but never had issue like this.
I have G.SKILL Ripjaws V 2x16GB 3200MHz 16-18-18-38 1.35V (Taiphoon Vurner says it is Samsung B-die, probably lower quality)
Before this I had same kit but in 2x8GB configuration, Hynix CJR (great overclock and can change primary timings)
Auto value - 16-18-18-18-38 - STABLE
Manual enter - 16-18-18-18-38 - NOT STABLE
Can anyone explain what is happening here?
