did you try the ram ocing profile the board has?
usually the safest way.
what ram is it? in the list of approved ram from asus?
is it 4x4gb or 2x8?
use something like cpuz and read-out what chips are on it...
I'v tried the d.o.c.p profile settings. 3200Mhz at 1.35v and 16-18-18-38, but I couldn't boot. I'm now running at 3066Mhz and 1.37v).
It's 2x8gb. There is a 2x4gb version on my ram in the ASUS qvl (F4-3200C16D-8GVKB) here http://dlcdnet.asus.com/pub/ASUS/mb/SocketAM4/STRIX_B350-F_GAMING/ROG_STRIX_B350-F_GAMING_Memory_QVL_20170519.pdf?_ga=2.181192423.1182970086.1510325031-1626251182.1510122625
I thought that there will be not much of a difference between them two , so I took the 2x8gb version , because it was the only "ok" 2666 to 3200 kit of ram in my county
I cant find what chips are on it
Could you please explain ? Googleing couldn't help me neither
Btw. I'm on the d.o.c.p profile atm , but I have lowered the speed and the voltage to 3066 and 1.37 respectively
