The Aorus Master Z390 9900k doesn't support running RAM at 3200 MHz.
Hello, I'm having an issue with my RAM clock. My system is running Aorus Master, and I've upgraded to 9900k at 5Ghz with a stable setting of 1.29v. Sometimes the RAM frequency spikes to 3066Hz, but it usually stays around 2800Hz. The RAM model is CMT32GX4M2C3200C16. I'm attaching my OC configuration.
I verify the RAM in another setup. If it meets the XPM profile on the new machine, I send the motherboard back or initiate a return. For the i9 10900k I found it either functions immediately or is sent back. That’s my process with the system below. It originally came with 3600 RAM but only supported 3200. When I transferred it to another computer, it worked perfectly. I added 4000 RAM to the i9 10900k, yet it still capped at 3200 and began freezing with blue screens before rebooting. I returned the motherboard because it was unused. A replacement arrived and it operates flawlessly now.
I kept the same graphics card, but changed the CPU pins. The old one worked at 3200 MHz, but both RAM sticks were in slots A1 and A2 because of the pin issues—B channel disappeared. Once I swapped in a new GPU and installed RAM in A2 and B2, I stopped seeing 3200 MHz anymore.
You're currently using a different BIOS version than the one I'm seeing. Are you also using XMP enabled? The DRAM remains incompatible with DDR4-3200 even after enabling it. For your 32GB memory, are you pairing two 16GB modules or four 8GB modules? If you raise the DRAM voltage to 1.40V, what results would you expect?
