Titanfall 3 goes black during combat transitions with my G.Skill 6400MHz RAM, why the wild FPS swings?

The screen just goes dead right when the loading bar hits 90%, and that kind of disconnect is absolutely lethal in a fast-paced fight. Looking back, I had the motherboard's Auto-Overclocking enabled, which caused my G.Skill Trident Z5 DDR5 6400 32GB to bounce wildly between 6380-6420MHz, triggering a memory validation error in the engine. My first instinct was to restart and tank the graphics settings, but it just crashed at the exact same spot—super frustrating. I eventually hopped into the BIOS, killed the unstable auto-configs, and hard-locked the frequency at 6400MHz while bumping the voltage from 1.35V to 1.38V. In AIDA64, my latency stabilized from a jittery 85-92ns down to a rock steady 78-82ns, and loading worked perfectly. I actually failed the first POST after locking the frequency, but loosening the tRCD timings got me back into Windows. RAM temps are now 48–54–℃ with voltage ripple under 0.01V. Ran three passes of MemTest86 and didn't see a single error, though the heat is still a bit high.
