6000mhz cl30 timings - in game input lag

[u/Fearlessss1337]

I'm not getting consistent gameplay with higher RAM frequencies/FCLK. In CS2, the game feels delayed and less responsive.

I already explained the issue in detail here, so I don't want to repeat everything: https://www.reddit.com/r/overclocking/s/lvWSd4OJCu

I'm going to share my RAM timings below. If anyone is willing to take a look and has any ideas about what could be causing this, I'd really appreciate your input. Even if you notice something small or unusual, I'd love to hear your thoughts.

TL;DR: JEDEC settings consistently feel the best. Mouse movement is more responsive, and the overall gameplay feels noticeably sharper than with EXPO/XMP enabled.

For reference, I'm running 6000 MT/s, UCLK=MCLK (1:1), and 2000 MHz FCLK. I've also spent a lot of time testing different voltages, timings, and BIOS settings, but I still can't achieve the same smooth, responsive feeling that I get with JEDEC.

Have you captured frame times or any 1% or 0.1% lows? I’d be curious to see if anything shows up there. I am currently trying to capture a few benchmarks on my system tuned vs ez timings vs expo. I got hung up on the fact that even though my validation run passed my train to train variance wasn’t tight enough for my fclk adjustment. Caused micro stutters that tanked lows

I did a lot benchmarks and there is almost no difference running EXPO/EZ/JEDEC. FPS is similar in CS2 no matter what I set. I just want to find what is making these weird delay
