My system runs the newest stable A.50 BIOS, while an A6 release exists but remains in beta. I plan to switch once the A6 becomes stable.
The next action is to raise the DRAM voltage in increments of 0.05V and observe the results. For DDR4, you can reach up to 1.45V.
3200Mhz is the JDEC standard. Previously it was just 2666Mhz for a while. Anything above JDEC is an exception, which is where XMP profiles are useful. The capacity to manage fast RAM depends on the CPU's IMC and the motherboard. Both should comfortably support speeds over 3200Mhz. It’s more likely you’re dealing with a subpar build.
I followed what this individual recommended. My 3000MHz setup had comparable problems. It turned out in XMP mode the voltage was defaulting to auto, around 1.2V. After turning XMP on and adjusting the setting to 1.35V, the issue resolved.
