Got around to tweaking memory for first time in a long time. Any obvious things to improve here, or errors or something that is not optimal? I don't know DDR4 memory tricks or theory, the guides with subsettings are very confusing and complex...
Sticks are G.Skill TridentZ DDR4-3400 C16 DC SR - 32GB from 2016 at 1.40v, Samsung b-die AFAIK. Motherboard is Asus X570-E with 5900X.
I did try C15 when the board was new and it didn't work but I haven't tried since. I tried tRFC 260 just now and it did not boot.
It is a bit of a pain when this mobo doesn't boot, I can't get into BIOS without backflashing with an USB stick and the backpanel button. On my two last previous boards (also Asus but the Hero series,) I could always get back into BIOS from the keyboard.
