Those voltages are the default ones, you only get the XMP voltages next time you restart the system from saved settings in BIOS.
You should check the voltages in Windows in HWinfo for example like I said.

see my karhu screen from the post above, those are the voltages applied after enabling the XMP 🙂
also those are the voltages in bios as well, shown in this screen from this issues#post885664" TARGET="_blank">post
default voltages are shown in the screen below
the SA voltage is 0.78V and MC voltage is 1.101V...
compared to XMP enabled: the SA voltage is 0.89V and MC voltage is 1.154V...
that's quite tiny increase for this "medium" 6400MHz XMP...
typically I would expect 1.23V for SA and 1.3V+ for MC after enabling XMP for 6400MHz

Hello, I also have an Asus ROG Maximus Z790 APEX motherboard with a 13900ks and a G.Skill 7800 DDR5 kit 32GB running XMP I and have CPU overclocked from 5.6GHz on the P cores to 5.8Ghz and the two remaining Star P cores left at 6Ghz. I have gaming stability issues and thought it was my DDR5 Overclock, but it turned out to be my CPU overclock and the "SVID Behavior" setting set on "Best Case Scenario" instead of "Auto". My CPU was not getting enough Voltage for gaming purposes, but was fine for booting into Windows 11 and running CPU-Z benchmarks. Once I changed the SVID Behavior to Auto and left everything else on Auto, I was able to Game without any issues. I am running the latest BIOS dated 3/31/2023 (BIOS "0904"). I have also before that I had been using BianBao.dev for beta BIOS updates. So definitely try updating to the latest BIOS 0904 and have optimized Defaults loaded in and only enable XMP I and try to do your gaming. If that provides stable, then go back and start overclocking, but I would advise initially to let the motherboard determine the CPU Core voltage and leave everything on "Auto" until you know you have a stable overclock setup.
Here are my system specs:
Intel 13900ks (CPU), Asus ROG Maximus Z790 APEX (motherboard), G.Skill 7800 XMP DDR5 32GB kit(RAM)(XMP I), Thermal Grizzly 12/13th gen (CPU Contact Frame), Corsair h170i Elite LCD 420mm AIO(6 push-pull fans)(Liquid Cooler), Gigabyte Gaming OC 4090 (GPU), Asus ROG Thor 1600 Watt (PSU)(*Total system is pulling up to 1150 watts while gaming with the CPU/RAM OC and 4090 @ default 450Watts), Corsair 1000D Super Tower (Case)
