Improving stability for KingBank Yin Jue DDR4 3600 in FF7 Rebirth
Just as a massive combo effect hits the screen, the fluidity is suddenly broken by a sharp frame drop—that contrast actually got me excited to dive into the memory controller. The KingBank Yin Jue DDR4 3600 was running at 3600MHz, but at 1.1V SOC, there was just enough signal interference to make the latency swing between 65-88ns. I first tried downclocking to 3200MHz, which stopped the drops but tanked my 1% lows from 55 FPS to 42 FPS. That was too much of a performance hit, so I went back to the BIOS and bumped the SOC voltage to 1.2V and locked the DRAM voltage at 1.38V. I ran Prime95 for 4 hours with zero errors, and the bandwidth stayed solid at 48-52GB/s. I did run into a heat issue where the RAM hit 62℃, but adding some cheap heatsinks brought it back down to 48-54℃. CPU is at 68-74℃ and VRMs are at 52-58℃. Stability is finally where it needs to be.
