Can adjusting priorities fix G.Skill DDR5 6400 lag in Ark 2?
The frequency on this RAM is like a lightning bolt, but the frame rate looks like an EKG monitor when I'm flying through massive bases—it's honestly ridiculous. The default timings on the G.Skill Trident Z Neo DDR5 6400 were causing latency swings between 65-90ns during heavy entity calculations, leaving the CPU idling for 10-20ms. I tried closing every single background app, but it only gained me 2 FPS, which was a joke. I went into the BIOS and tightened the secondary timing tRFC from 480 down to 400, while pushing the voltage to 1.40V. Using RTSS, I saw the frame time variance collapse from a wild 16-50ms down to a tight 12-18ms. I actually pushed tRCD too low at one point and the game crashed every ten minutes, so I had to back it off by 2 cycles to get it stable. RAM temps are hitting 52-58℃ and the VRMs are around 65-70℃. I exported the logs to verify, and the frame times are now rock steady at 12-18ms. It's finally playable.
