Not possible to operate memory above 2133MHz clock speed.
Not possible to operate memory above 2133MHz clock speed.
Hey there, I just switched from a 16GB 3000MHz TridentZ RAM to a 32GB 3200MHz Corsair Vengeance kit. After adjusting my D.O.C.P settings in the BIOS for the Ryzen platform, my PC only boots when it's at 2133MHz. Anything above that and it enters recovery mode. My memory voltage is currently between 1.2 GHz and 1.35 GHz. What might be causing this issue?
The RAM in the QVL is typically not on the list, but it can sometimes fail. CPU and motherboard details are also needed for a full explanation.
Processor: Ryzen 7 2700X MOBO: ASUS TUF B450M-Plus Also I’m not sure about the QVL
The QVL compiles a complete inventory of memory modules that offer support.
Avoid thinking about QVL anymore. It only counted when this technology was brand new. It’s because your CPU memory controller now officially backs 2933mhz. Anything higher is just chance or needs adjustment for system stability. If not, it won’t post and will lower to a safe POST at 2133mhz. Honestly, I’d pick 3200mhz (not DOCP) and let the timing auto-detect. Ryzen isn’t too concerned with timing in synthetic tests, and I haven’t noticed a gap between CL14 and CL18 on my builds. If it remains unstable, boost voltage up to 1.35v (up to 1.5v technically, but I’d stick to 1.4v max).
I switched off DOCP, adjusted MemFreq to 3200MHz and tried the same settings, but it didn’t boot. Then I lowered the frequency to 2933MHz and experimented with different timings, though nothing worked except Auto mode at 2133MHz.
