Cannot run memory at higher than D.O.C.P 2133MHz

[hello_world98]

Hey guys, I just upgraded from a 16Gb 3000MHz TridentZ RAM kit to a 32Gb 3200MHz Corsair Vengeance kit, and after re-configuring my D.O.C.P settings in the BIOS (Ryzen platform), my PC wont post unless its at 2133MHz. Anything higher and it boots into recovery mode. My memory voltage is currently at 1.2 GHz - 1.35 GHz. What could be going wrong?

Is the memory on the QVL, usually memory not on the list will work but sometimes it won't at all. What's the CPU and motherboard too?

Did you install the RAM into the correct slots?

CPU: Ryzen 7 2700X
MOBO: ASUS TUF B450M-Plus

Also I do not know what the QVL is

There are only 4 slots and they are all populated

The QVL lists all the support memory modules

It looks like it is not on the QVL for Ryzen 2000 series processors. Is this the problem?

Try clear CMOS. Sometimes the sub-timings from the older RAM get stuck.

Stop worrying about QVL.  Only mattered when this tech was new.

 

Its because your CPU memory controller officially supports 2933mhz frequency.  Anything over that is luck, or needs tuned to meet the system for stability.  If not, it wont post and will downclock to a guaranteed POST (2133mhz)

 

EDIT - If it were me, I would just select 3200mhz (not DOCP) and let the timings be found.  Ryzen doesn't care that much at all about timings in synthetic benchmarks, and I cant find a difference between CL14 and CL18 on my kits.  If still unstable, add voltage up to 1.35v (up to 1.5v technically but that's up to you I personally would never go past 1.4v)

I turned off DOCP and set my MemFreq to 3200MHz and the timings to 18-18-18-18 and it still wouldn't boot. Then I dialed down the frequency to 2933MHz and played around with the timings from there but nothing gave me a boot, still only when i set it to Auto 2133MHz
