Why is my Corsair Vengeance RGB DDR5 6400MHz glitching?

Hitting 300 km/h in a full sprint and the screen just starts tearing—it's a nightmare at 4K. The default XMP profile on the Corsair Vengeance RGB DDR5 6400MHz puts way too much stress on the memory controller on some boards, causing frame times to swing wildly between 8.2ms and 24.5ms. I tried enabling Low Latency Mode in the drivers first, but that was a waste of time; it didn't fix the stutters and actually caused a 1-second hard freeze during scene transitions. I eventually dove into the BIOS, bumped the SoC voltage from 1.2V to 1.25V, and tightened tRFC from 480 down to 420. Running AIDA64 stress tests showed latency dropping from 72ns to a steady 64-68ns, and frame generation finally settled between 8.5-11.2ms. I actually hit a BSOD the first time I tried to push the timings too hard, only getting it stable after loosening the secondary timings by 2 units. Memory temps stayed around 56-62℃ while the VRMs hit 68-74℃. HWiNFO confirmed the load curve is finally smooth, with frame times locked at 8.5-11.2ms.
