Everything Stable but reboots hang on DRAM light when EXPO is enabled. Timings to blame?

    OCCT 1hr Tests come back clean on both modes. I can game multiple hours with both modes on. Have not had a single BSOD. Only glitch is fail to reboot when hitting restart (only on EXPO), afraid that may cause issues with updates so i am running on 4800mhz.

    Tried:

    Changing Ram kit, Same exact behavior (QVL and Placement good).

    Reseating CPU (Cooler not extremly tight).

    Bios Update (last one i had was a year old).

    MCR On and Off.

    Setting a 5400 Expo profile.

    Setting 6k and 5.4k XMP profiles.

    No RGB header/control; Off in bios, only software running is razer chroma and thats just for mouse & keyboard.

    Havent tried:

    Getting down and dirty with manual timings, but i have tried EXPO Timings and setting speet to 4800MTs. Same issue appears.

    Really I think the only culprit left is the MOBO having some niche error. CMOS cleared after the CPU reseating and i had the same issue.

    The Memory controler for the CPU could also be to blame, but wouldnt I be seeing instability and crashes while running EXPO?

    It really is not that big of a problem, its just annoying.

    Specs:

    B650 Tomahawk, Latest bios (non-beta)

    (Old Ram) G.SKILL F5-6000J3038F16GX2-TZ5NR

    (New Ram) KF560C30BBEK2-32

    7700x

    7900XT
