Just to understand, which memory kit do have now? G.Skill or another one?
Normally, you have to increase the ram voltage for overclocked speed for stability. DOCP, which in other word's is the memory profile for AMD, should be working just fine with your processor however you might want to manually tweak the multiplier for the cpu & base clock. I have GoodRam 64GB 3000Mhz memory kit running under the profile, with 3.8Ghz on the cores. It's not listed under the QVL however everything's been running just fine from the first day.
So the profile changed the base clock to 102.3, I manually tweaked the cpu multiplier and left everything under AUTO. It booted just fine.
Each profile should change the setting's automatically.
