Is Corsair Vengeance 6400MHz causing lag in massive battles?
The moment a thousand-man battle kicked off, the entire screen would just lock up for about two seconds, which is absolute torture when you're in the middle of a fight. The default timings on the Corsair Vengeance RGB DDR5 6400MHz were struggling with the massive unit data, with tRFC being way too high, causing latency spikes of 115-135ns. I tried updating to the latest motherboard BIOS, but while it helped with some minor bugs, the freezes still happened randomly during chaos, which was incredibly frustrating. I eventually went into the Advanced Memory settings in BIOS, crushed the tRFC from 480 down to 340, and bumped the VDDQ voltage from 1.25V to 1.32V. Monitoring with RTSS, the frame time swings of 15-88ms finally tightened up to a consistent 12-17ms. I actually went too far on the timings at first and got a Blue Screen during the loading screen, so I had to loosen the tRCD by two notches to get it stable. Memory temps sat between 54-60℃ with fans at 1200 RPM. 3DMark stress tests confirmed the latency is now under control, and the input lag is gone.
