Logitech G HUB is application SW with severe CPU overhead (wastes CPU cycles & causes excessive context switching), which can contribute to macrostuttering (which is what you're describing instead, at least imo)
Use Logitech Gaming Software (LGS) instead

thanks its uninstalled by now

Aida64 & Cinebench are not stress testing applications to verify stability of a system.
They are benchmarking applications
I will quote @shrimps, who worded elegantly on what stability entails:

“No amount of memory stress testing is enough, stress testing is just an approximation of stability.
Learn patterns of your memory/imc and apply an overclock that not only passes tests, but also has headroom for when conditions change.”

jokes on me. did the aida64 "burn in" test for everything except gpu and ssd.

Here are my recommendations, in terms of hardware:
- Your kit is not on the QVL of your motherboard, meaning possibility of instability is extremely possible when enabling EXPO.
- Considering that CS2 does not scale as much with lower R/W RAM latency or higher RAM bandwidth (source), I would recommend that you experiment with EXPO disabled and reinstall your OS (23H2 or 24H2) to iron out any potential corruption from a (very likely) unstable RAM profile.
- If you want to go down the RAM stress testing route, use app sw such as: RamTestPro (purple icon) for +16h (ideally with Furmark to simulate a more realistic workload, but u can try without), ycruncher, OCCT, HCI Memtest etc.
Linpack does not work on AMD, as it relies on Intel specific libraries to do the linear algebra. If you come across someone recommending it for AMD, don't take heed.
Anecdotally, Karhu & TM5 seem to miss easy errors on DDR5 as of the time of writing, so I would avoid using those.

not sure if this is just on my side or i made a mistakte here but for me this kit show up under the QVL (see attached img).
can u please doubble check? ive orderd antoher kit a few days ago just to see if there is any difference.
for reference (F5-6000J3038F16GX2-TZ5NR)
runnig asynchronous for testing right now. what would u reccomend ?

current bios config:
expo: expo 1
fclk: asynchronous
pbo: disabled
smt: disabled
wfif: disabled
iGPU: disabled
bluetooth: disabled
game mode: disabled
re bar: on (default on most systems i guess)
rest is default.

would u recomend disabling XHCI hand-off ? in theory i dont need this but not a 100% sure tho

What temps do you consider “fine”? This is very important to note.

so that i dont thermal throttle cpu=55 gpu=70

You could also provide a ZenTimings screenshot to evaluate other settings of your motherboard.

here was an error see img. thanks

I find Game Mode to be redundant, you can disable SMT instead of using Game Mode.

PBO should be avoided at all cost, as it increases jitter from the variable clock rate and thus can incur microstuttering behavior.

did this. frametimes seems to be more narrow but spkies still persitsts

Why are you running -noreflex and Nvidia's Low Latency setting set to "On"?
If you are GPU limited with your 3080ti, opt for Reflex or use the in-game frame rate limiter to achieve lower GPU usage.
As for using RTSS async as a external frame limiter solution, bear in mind that it adds an additional 1 frame of latency (400fps = 2,5ms), while RTSS front-edge / back-edge sync (best for frametimes) causes an additional 2 frames of added latency (5ms)

Why are you using FSO (used to be called eFSE) disabled?
Have you verified what Presentation Mode your game is running in when you disable it, which is done by ticking the setting on CS2.exe's “Properties” window?
I would advise against doing so.

many ppl on the subreddit recomded this. disable relfex in game an "re" enable on driver level.
can not find the link im sorry.
but a user in this thread also quotes this. no need for a link here.
would love to use the ingame frame limiter but i think this is still broken. if fixed by now then must be silently
FSO disable unchekd by now. yes allways in fullcreen.

Considering that you are on a XL2546, refer to: https://boringboredom.github.io/tools/fpscapcalculator
If you are using DyAc, it will exacerbate any macrostuttering or microstuttering you have due to the lower MPRT you're targetting.
Refer to “How to use strobing competitively and beautifully”

did this game feels more snappy.

I would also avoid using W11 drivers for your NIC, but I don't have any data on how Realtek's 5GbE NIC behaves.

thanks. currently using: TP-Link UE300C USB C
had noticable lees input lag after switching from onboard to usb. did this last day before applying tweeks out of this forum so maybe a solution for some one facing this issue.

i tried many different network cards. but the best for me is TP-Link UE300 USB dongle. I literally can hold angles now. But let windows install the drivers and disable any energy saving features

I was getting this frametime stutter on a 9950 x3d in a completely new prebuilt PC and my old PC. Both amd one not x3d tho.

I solved it on my end by updating my realtek audio drivers to the most up-to-date audio drivers for my motherboard. The old drivers, let you equalize audio levels so I was addicted to them. I had the microstutter on 2 PCs. Because of this same driver.

And I also used process lasso to limit(affinity) CS2 to my x3d cache/cores only. I also did extra unnecessary tweaking to background processes while avoiding system processes (left them alone). To those extra processes, I affinity them all away from my x3d cores/cache.

Try these two things.

An extra thing I did to limit a stutter, that seems to affect frametimes but is actually valve's tunneling on official matchmaking servers in my testing. Device Manager > Find your ethernet adapter right click > Properties > Advanced > Set Transmit Buffers to 1024 and Receive Buffers to 2048 > click ok.
The last one was just me and my ISP having issues with valve's servers. I don't get this same stutter on faceit for example.

Hope this helps. Was driving me mad.

can you give me the same screen like mine to see yours ? i dont use audio driver i use the default windows,the second screen is from a program named "real".

See that enhancements tab, thats from the windows audio driver. I don't know why bit it causes a microstutter at least for me. only in CS2...

Find your soundcard or motherboard, and get the latest driver from their own website. Goto DEVICE MANAGER, not sound properties. Search Device manager in start or type "devmgmt.msc" in windowskey+r (run)

Will look like this, If you have trouble, finding it yourself you should be able to type motherboard model name into google or ask chatgpt with model name and tell it to find you the driver. Make sure its right though.

Sorry I just misread and replied to you, thinking you were the original poster. I don't want to run that audio latency thing.

4060ti

Why are you trolling the OP, when he's just asking for help? You're recommending him a severely downgrade GPU compared to what he already has?....

power consumption

Dumb thing, can you try running it in 1920x1080 native and no scaling in nvidia control panel? I had the same issue running 4:3 stretched but then it works fine in native.

Some questions in no particular order to help narrow it down as I personally have a 9800x3d:

1. Have you updated your bios?
2. Do you have the latest chipset drivers?
3. Have you tested with default windows settings on a fresh install? (non-debloated aka gamebar not being removed and power plan staying on balanced?)
4. 2x48gb ram cl28 6000 is almost certainly not stable, have you tested things out without expo? is your ram set to 1:1 in bios with expo enabled, if so can you test 2:1 to see if it improves?
5. Gamemode on is not better by any means, if this is the case then its likely that something isn't stable such as your soc voltage being too low. What is your soc voltage set to?
6. Have you tested with pbo disabled / set to advanced with motherboard limits but without CO enabled?
7. Did you install your chipset drivers / realtek drivers through your mobo website or from amd/realteks official website?
8. Have you tested enabling c-states in bios?
9. Do you have iGPU enabled/disabled in bios?
11. Could you share what you modified in your bios?
12. Which way did you install 24h2? was it within windows or a fresh install through usb? if it was within windows - did you have a different CPU installed previously?
13. Did you try nvidia driver version 566.36? Did you DDU in safemode with internet disabled while installing it?
14. Did you install windows with a microsoft account or local account?

For stability testing I recommend using OCCT for starters to get a quick indicator if something is wrong - just use the default test for CPU and CPU+RAM for now, before doing this I recommend loading factory defaults on bios and only enabling expo.

sorry for late reply.
1. yes
2.yes
3.no but ll do next weekend
4.1:2 1:1 seems no real difference. expo off similar or better results in case of stuttering but could also be placebo.
swaped in 6000mt/s cl 30-38 F5-6000J3038F16GX2-TZ5NR
spikes still persist
5.soc voltage: 1.243 (must be default value the board provides didnt modify this setting)
6.not now but i ll
7.i allways use the mobo page. which would you recomend?
8.no. was not sure about tempering with this setting (can u explain?)
9.disabled
11.current bios config:
expo: expo 1
eCLK: synchronous
pbo: disabled (default)
smt: disabled
wfif: disabled
Realtek USB Audio: disabled (i use external soundcard )
iGPU: disabled
bluetooth: disabled
game mode: disabled (default)
re bar: on (default on most systems i guess)
rest is default.
12. no. clean install w10 then inplace upgrade. could be an issuse. ll test fresh 23h2.3 soon
13. no but ll give this a try. yes always this way
14. i guess ms account. does this make a huge diffenerence ?

Apologies for the confusion, you're right. I somehow missed it in the QVL at the time of writing.
Regardless, there's still a possibility that your IMC may not support such tight CL timing or other secondary / tertiary timings, especially at the designated voltage (1,35v) and RAM kit density.
EXPO does not guarantee stability at all. Refer my recommendation of either running EXPO disabled or stress testing your 2 x 48GB kit)
Higher density = higher chance of instability. Especially at 96GB
You could also test 5200MHz with XMP timings as a compromise. It depends on your CPU's & motherboard's capabilities
Ex-AMD employee Robert Hallock, slightly before Zen4 release, was personally fond of 5200MHz low CL kits instead of 6000MHz kits.
He also recommended setting the FCLK:UCLK:MCLK ratio to Auto:1:1 (e.g.: 1733 : 2600 : 2600)
The +800MHz bump might seem miniscule to us, but it is severe stress on the CPU & mobo
Keep in mind that even 6000MHz 2x16GB kits may be unstable on some IMC & mobo combinations
Reinstalling upon changing RAM profile is also advised, since corruption on OS may occur from a unstable profile.

Following AMD's server performance tuning guides documentation from their support site might be useful in figuring out other ways to eliminate your stuttering.
Refer to the link in my signature (AM4 / AM5 system tuning considerations), where I've linked a few sources in regards to AMD
I personally believe what you're dealing with is just a case of RAM instability
AIDA64 is not reliable in any way to evaluate your performance or stability, use the other application software I've recommended in my previous post.

It's usually best to keep XHCI setting at the default of your motherboard, but disabled should also be fine.
It depends on the USB drivers you are using with your OS, which I assume are just the default Microsoft ones (wdf0100.sys)
I did see some users mention ReBar causing stuttering in some games & some systems, YMMV.

The general guideline I usually follow online is, if someone doesn't substantiate his claims with repeatable testing data, I ignore his opinion. The optimisation community is filled to the brim with misinformation.
Yes, the in-game frame limiter (fps_max) is sub-par & thus causes frame pacing issue, but it is the only no overhead (no additional penalty) solution which you can use in CS2, since external solutions (RTSS, NVCP) add a noticable delay to overall system latency

Yes, backlight strobing (DyAc) makes visual clarity in motion (e.g. spraying) substantially clearer.
Eye strain is a complaint which some voice, but to some, the trade-off is worth it..

I'm not sold on the idea that these USB NIC's (Realtek-based) have a noticable effect compared to on-board solutions.
In fact, USB NICs add a CPU overhead compared to PCIe based solutions due to MS' stock USB drivers being subpar for the task.
They add unnecessary jitter, in my experience.
In fact, minimising the amount of USB devices you have connected & finding the best performing DPC/ISR drivers contribute greatly to overall reduction to jitter in a system.
You've mentioned you have a external sound card, which model is it and what interconnect are you using with it?

Overall, there's only so much you can do in CS2 as the title is very unoptimised.
It would be good if you could test out other titles to see if the stuttering persists.
