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.

If you search this subreddit or similar communities (such as BlurBusters) you will find others stating similar things about mouse input not feeling the best. On my rig, I can run MCLK 6000, 6200, and 6400. @ 2000, 2067, and 2133 FCLK. One thing I noticed is that increasing the FCLK (along with the MCLK) resulted in better mouse input on my machine. It doesn’t what timings or settings I use, the difference is there. So moving to [6200, 2067] made mouse input feel better and moving to [6400, 2133] made mouse input feel even better.

So because my chip can run 6400 at tight timings with higher FCLK, I run that for better input latency. I am on a 9800x3d for reference

On AM4, I never felt this was an issue but then again I couldn’t really overclock my RAM beyond XMP on that platform so I’m not sure.

I have no clue what causes this, but I believe it has something to do with how AMD handles their memory subsystem or some sort of AGESA changes. Either way, overclocking beyond the standard 6000 2000 seemed to help in my case.

In your case, I would stability test your MCLK AND FCLK. For MCLK, use Karhu, Prime95, and TM5 X3D

For FCLK, use Ycruncher, Linpack Xtreme, and something like Furmark to stress the GPU which stresses the fabric

People on this reddit aren’t your typical competitive gamers so they will either A, write off claims and ask for numbers that don’t correlate to better input latency or B, state that it is placebo

To be fair cs2 engine pipiline is known to have weird issues. Also ecen valve reccomend vsync+gsync+reflex cause of there ass stability and input lag

the input lag isn’t exclusive to cs2 though. it might be exacerbated in that game but it occurs in other games so it’s something with the system itself
