I just wanted to share my findings I picked up from another user over at Asus Forums.
Like most, I've had a hard time with my ram and this board but I have found these settings stable on my Asus PRIME B350 - PLUS with my G.Skill Flare X F4-3200C14D-16GFX:
DOCP Speed 3200 MHz
VDDRCR SOC @ 1.1500v
DRAM @ 1.3900v
VTTDDR @ 0.6750v
ProcODT @ 48 Ohms
My ram timings are 14-14-14-34 T1
On this board, I had to first activate the DOCP settings which auto raised the VDDRCR SOC voltage to 1.1 from the default 0.9. This allowed me to raised the voltage by the extra 0.05 needed otherwise I would have been limited to raising it by only 0.20 from the 0.90 default if I did not activate DOCP profile.
I hope this will help someone that's had the same problems!
And both of you successfully operated at 3200MHz? If so, I think I need full detail of BIOS setting, Actually I own ASRock X370 Professional Gaming with Galax 3600MHz, but I've just helped my friend built one AMD Ryzen 5 1600 with ASUS Prime B350-Plus and G.Skill Flare X 3200MHz kit.
Hi, I have the same motherboard and ram with the Ryzen 7 1700X. When I set the default DOCP with 3200MHZ my PC keeps restarting. I had to edit the DOCP profile and change it to 3000MHZ in order turn on. Is the normal ? I need to edit any settings in 3200MHZ profile in order to get it working ?
