Hi there. I've been a little out of pace with newest hardware, latest build I did was in 2012 with a Xeon W3520 that did its job nicely oc'ed @ 4.0Ghz.
In those times there was not too much fuss about RAM if you did run it at spec.

So this time I went AMD with their new Ryzen CPU, got a 1700, Asus Prime B350 Ultra (latest bios) and G.Skill Ripjaws V F4-3200C16D-16GVKB (2x8Gb), as I researched as Ryzen seems to like a big memory bandwidth. Runs beautifully, quick overclock to 3.6 Ghz with default cooler and voltage, very nice.

However, I'm unable to run the RAM @ 3200 Mhz. I can choose DOCP 3200 Mhz 16-18-18-39 1.35v from AITweaker instead of auto, saving and rebooting just gives me 3 long beeps until it posts in safe mode.

I tried to manually set timings (but there are so many of them) and voltages, same thing.

Is this a lost case, or am I doing something wrong? I really didn't pay a premium for DDR4-3200 to run it @ 2133...

Thanks in advance.

 
Solution
Test the highest frequency you can achieve with DOCP enabled.

You may need to boost SoC Voltage to reach a higher frequency.

Technically the memory kit is not certified for AMD Ryzen.
