How to fix memory timing instability on MSI MPG Z890 EDGE TI?
The default XMP on this board is an absolute joke; the moment the load gets heavy, the frames just tank. On the MSI MPG Z890 EDGE TI, running 8000MHz RAM caused the SoC voltage to wobble around 1.2V, leading to 15-22ms latency spikes when handling huge texture assets, dropping my FPS from 90 down to 30. I tried 'Auto Overclocking' in the BIOS, but that was a disaster—I was getting blue screens every hour. I finally manually locked the SoC voltage to 1.25V and loosened the timings from C36 to C38 to give it some breathing room. After 4 passes of MemTest86, my error count went from 12 down to zero, and the stutters are completely gone. I did notice the RAM hit 62℃ after the voltage bump, so I had to crank up the fan curve to bring it back down to 52℃ - 55℃. The system is incredibly responsive now, and the input lag is gone.
