Any advice on timing numbers to adjust given this situation?

Upgraded my wall-mount garagePC to a 7700 cpu and some black-Friday free 16-gig ram kits that came with mobo from Newegg. Tried tuning the RAM and after a few iterations got to CL30 levels I’ve used on other kits of ddr5 I have.

Passed OCCT tests and TestMem and I was a little shocked/impressed until I sat down to start using the PC. Basic YouTube videos played audio fine but video glitched like crazy. Switching back to standard EXPO settings stopped the glitching.

A few notes: 2x 16gig kits (4sticks x8gb) of T-force Delta FF4D516G6000HC38ADC01 38-38-38-78

Also, using the igpu because wall mount garagePC used for everything but gaming.
