How to stabilize DDR5 on Soyo SY-Classic B660M for Ishin?
Seeing Kyoto in detail is amazing, but the random crashes were a total buzzkill. The Soyo SY-Classic B660M memory controller struggles with high-frequency DDR5, with SoC voltage swinging wildly between 1.1V and 1.2V, causing checksum errors during large page allocations. I tried enabling Windows Game Mode, but that did absolutely nothing. I went into the BIOS, locked the SoC voltage at 1.25V, and tightened the timings from 36-36-36-76 to 32-38-38-72. In AIDA64, read speeds jumped from 48GB/s to 54-58GB/s with zero errors over three hours. My boot time slowed down by about 10 seconds initially, but disabling the memory training option fixed that. RAM temps are 52-58℃ and CPU is 68-74℃. Benchmarks show the system is finally stable, with fans steady at 1400-1600 RPM.
