How to fix response delay on Corsair Vengeance LPX DDR4 3200?
When performing a quick-draw strike, I felt a delay of a fraction of a second. In an action game, that's basically fatal. Testing software revealed that my Corsair Vengeance LPX DDR4 3200MHz latency was jumping from 75 ns to 98 ns under high CPU load, causing input response to fluctuate between 6-14 ms. I tried swapping the RAM slots first, but the latency spikes happened regardless of the slot, which made me realize this was a timing issue. I went into the BIOS and tightened the primary timings from 16-18-18-36 to 16-16-16-34, and increased the voltage to 1.38V. My input lag tool showed the response time stabilize from a jumpy 8-16 ms down to a consistent 4-7 ms. I noticed some weird recognition delays during cold boots after this, which I fixed by nudging the voltage up to 1.40V. RAM temps are now 50-56℃ and the chipset is at 55-60℃. I've verified the final parameters using a professional response-time analyzer.
