How to lock voltage for G.Skill Trident Z RGB DDR4 3600?
Whenever I unleashed a full-screen skill in a raid, my FPS would dive from 120 down to 45. It was a total performance cliff. I discovered that the auto-voltage on the G.Skill Trident Z RGB DDR4 3600 was bouncing between 1.35V and 1.40V during heavy load spikes, causing the memory controller to choke. I tried the 'Ultimate Performance' power plan in Windows, but that actually made the voltage swings worse—totally naive move on my part. I went into the advanced voltage settings in the BIOS and hard-locked the RAM at 1.38V, while setting tRFC to 560 cycles. Using a latency monitor, I saw the memory latency tighten from a shaky 75-95ns to a consistent 68-72ns. The smoothness is night and day now. The sticks did hit 58℃ at first, but I adjusted my fan curves to compensate. VRM temps are around 55-61℃. I switched the mode from Balanced to Extreme via the software, and it's rock steady.
