I'm getting weird screen flickers at high speeds in Forza Horizon 5 with XMP on my Galax B760M; is this a timing issue?

Every time I pushed past 300km/h, the edges of the screen would start flickering with these ghostly colors—it was an absolute anxiety trip. The Galax B760M White Phantom's D4 RAM at XMP 3200MHz was showing voltage swings between 1.1V and 1.3V, causing the memory controller to choke on huge scene data. I tried lowering the graphics settings, but the flickering persisted, which told me it was a hardware stability issue. I went into BIOS and loosened tRFC from 560 to 640, then manually set the SoC voltage to 1.15V. After 5 full passes of MemTest86, the error count dropped from 3 per hour to zero, and the flickering stopped completely. I did try pushing for 3600MHz, but the system entered a boot loop from hell until I backed it off to 3200MHz. RAM temps are sitting at 44-50℃, and the VRM area is around 58-63℃. The in-game telemetry now shows a perfectly stable data stream.
