someone fixed netcode and even hitreg and desync just by ram timings...

Finally someone WHO understands and ist Not dumb enough to believe what this Guy winkli showing. That Guy fixed fixed nothing and never will.

And let me Tell you that "hitreg" ist not clientsided. Its totally Internet based and there nothing on your end to improve this. Same as desync. So If someone came and telling you that he fixed hitreg/desync with simple system tweaks, than you can be Sure that this Guy is a Liar/fool.

Only way to improve this is VPN or changing place or your ISP ist changing Something heavily in your Side.

You can only fix Input/Output lag from the system, thats possible but that doesnt mean that your Network ist also fixed. Those two Things are two differents and are Not connected together. You can have good hitreg with Input lag or None Input lag with Bad hitreg.

I fixed my hitreg/desync problems with some new settings in MSI Utility AND RAM Settings.
How good are the last few frames and the absolute lowest DPC latency if for some reason it doesn't run in sync with the game?
I then thought to myself, there are probably good frames and bad frames. I wanted only the good frames to remain.

I set the most settings in msi tool to undefined and low but have all devices that support msi mode in msi mode
no msi mode for the ethernet adapter 219V.
Interrupt affinity settings only for gpu and mouse (GPU set core to best low 1%)

The biggest impact was change the ram timings. I allways had XMP Profile active. After i overlock the ram a little and
try to set up some timings by myself it changed everything. Need a little bit time and cmos clears to find the working timings for crash-free play but then i found some and it works well. The timings are also a lot lower than those specified in xmp.

I think now the deeper you dive into optimizing, the more important it becomes to know 100% exactly which setting does what in the system or which settings change related things. If, like me, you simply try to optimize everything with the best settings, there is a risk that things will not harmonize properly and it will lead to desynchronization and resulting Hitreg problems.
I also tried to ask a few professionals about their settings. Some just know where the PC turns on and still play like gods...wtf?!!!

you don't turn a gtx970 and a gen7 cpu into a 4090 with gen13 close to the server...i or we have to deal with it.

Similar story here. I currently run cl 11 @ 2400mhz dual channel at 1.35V. Significant responsivness boost in this regard, despite the lost fps becase of lower frequency. My current MSI Util v3 settings are NVME in MSI Mode (High Priority). Realtek Internet not in MSI Mode, (Low Priority) and GPU (1080ti) not in MSI mode, (Normal Priority), rest are unchecked and undefined. This works very good for me.
