I just grabbed some 4 16gig Corsair 3600 sticks for my Asus X570 prime with a 5900X. I never looked on the QVL. About once a week I was getting a blue screen of death saying memory errors. The mem was set up with XMP and PBO and was running at 1.350. After a few shut downs I set it to 1.355 and have not had a crash since (fingers crossed). Question: Could such a tiny tweak actually make memory more stable or should I do some sort of tests to see if I can recreate the condition for further trouble shooting?
