How to tune memory stability on MSI MPG Z890 EDGE TI WIFI?
Seeing the memory latency drop from 65 ns to 58 ns was a huge win; the difference in Phantom Blade Zero's fast combat is night and day. When I first enabled the XMP profile, the system would just blue-screen ten minutes into the game. The memory controller was clearly unstable around 1.2 V, which taught me not to trust 'one-click' presets. I manually bumped the SoC voltage to 1.25 V and tightened the timings from 36-36-36 to 34-36-34. In AIDA64, I saw read/write speeds jump by about 4.2 GB/s. I did hit some memory parity errors early on, but increasing the DRAM voltage to 1.38 V cleared them up. Now, memory temps sit between 48℃ - 53℃ and the game is buttery smooth with zero micro-stutters. Squeezing every bit of potential out of the hardware is a grind, but the FPS gains are real. I switched the memory mode from Auto to Manual in the BIOS to lock this in, and the temps remain stable at 48℃ - 53℃.
