Does the Proart Z790 support DDR5 7800MHz or not?

I purchased TEAMGROUP T-Force Delta RGB DDR5 Ram 32GB (2x16GB) 7800MHz (FF3D532G7800HC36DDC01), and it is indeed listed in the QVL (Qualified Vendor List). However, regardless of whether I choose XMP I, XMP II, or XMP tweaked, I cannot pass any RAM tests, and sometimes I even encounter BSOD (Blue Screen of Death). The product specifications do mention a maximum of 7200MHz (OC), but the QVL shows higher speeds than 7200?

Even when I maintain the timings at 38-48-48-84 and voltage at 1.4V, I can't achieve stability even when downclocking to 7600 or 7400. Ultimately, it remains stable at 7200, and I can even lower the voltage to 1.35V with timings set to 34-42-42-84...
