Why is my Corsair Vengeance 96GB kit lagging in FF15?
Whenever I hit the center of Insomnia, the memory response time just spikes to 95-110ns, causing these annoying micro-stutters that felt like old-school dual-channel conflicts. I honestly thought 96GB would be overkill for this, but it still lagged. I tried enabling Large Page memory support in Windows, which was a total waste of time—it actually tanked my minimums to 42 FPS. I eventually dove into the BIOS Advanced Memory settings, locked the memory controller frequency at 2000MHz, and manually set the tRFC to a tight 480-520ns range. Using HWiNFO, I watched the latency shrink from 98-115ns down to a crisp 72-78ns, and frame times stabilized from 15.2-22.8ms to 11.1-13.4ms. My first attempt with XMP was a disaster and wouldn't even boot; I had to bump the voltage to 1.4V and tweak timings manually to get it to post. Even though the sticks still run hot at 58-63℃ under load, the snappiness is night and day. Verified the read curves with AIDA64, and the frame time is now locked at 11.1-13.4ms.
