I just put together a new PC with a Gigabyte Z790 Eagle AX motherboard, an Intel i7 14700F, an NZXT Kraken cooler, a Gigabyte 5060 Ti Aero OC, Corsair Vengeance 32GB (2x16GB) DDR5 at 6400 MHz with AMD EXPO and Intel XMP support, a Corsair 1000W Platinum power supply, and a Samsung 990 Pro 2TB M.2 SSD. After assembling everything and installing the drivers, I tried enabling XMP, but it only presents two profiles: XMP and EXPO. When I enable either, my system enters a constant boot loop, and if it manages to boot, it crashes and returns to the boot loop. The system runs fine at the default speed of 4800 MHz. Is there any way to fix this issue or get XMP working? By the way, could my BIOS version (F3) be causing this?

You should definitely try updating your BIOS first; that could fix the issue. If that doesn’t do the trick, you might need to tweak the settings manually for overclocking. Sometimes just dropping one step in MT/s can be enough, but be prepared for a bit of trial and error.
Yes, definitely perform that BIOS update. Once that’s done, don’t enable XMP or EXPO just yet. Boot into Windows and download CPU-Z to check the memory vendor for your RAM. Depending on whether it's Micron, Samsung, or SK Hynix, you might want to look up some timing guides and manually set the timings in BIOS. Also, play around with the voltages; you might need about 1.2V for Vsa and 1.35V for VDDQ1/VDDQ2 and DRAM, then test for stability afterward.
Looking at the XMP details in CPU-Z, it shows timings of 36-48-48-104 at 1.35V. However, on the Gigabyte support page, it says for 6400 MHz, the timings should actually be 36-48-48-104 at 1.4V. Isn't the XMP profile supposed to match this info? This has me confused!
