How to reduce memory latency on the Ryzen 7 9800X3D?
That absolute pinpoint precision is finally back. Before this, during fast rotations, the game had this subtle 'sticky' feeling that was driving me insane. The 9800X3D's V-Cache should be a beast, but my monitoring showed memory latency jittering between 85-98ns at peak clocks, which absolutely murdered my 1% lows. I first tried cranking the memory voltage to force stability, but while average FPS went up by 5, the minimums actually got worse. I realized the voltage curve was the culprit. I hopped into the BIOS, set the PBO to a -20mV negative offset, and tightened the secondary memory timings. In actual matches, that screen tearing during fast turns completely vanished. I did push it too far once and got a BSOD while booting to desktop, so I backed it off to -15mV for total stability. CPU temps stayed between 65-72℃. Latency analyzer confirms the response time is way down now.
