[SOLVED] Stuttering on new prebuilt system

[FallSkar]

Hello guys, I recently bought myself a prebuilt system with the following specs

Mobo: ASUS Prime B550M-K
CPU: AMD Ryzen 7 5700G
GPU: AMD RX 6600 XT
RAM: Kingston Single Channel 16 GB DDR4 3200 MHZ
Storage: HDD 1TB + SSD 1TB NVME m.2
PSU: No ideea on brand and certification but it's a 500W

Here is the link of the local shop I bought it from in case it's needed:
Sistem Desktop PC MYRIA Style V73 Powered by ASUS, AMD Ryzen 7 5700G pana la 4.6GHz, 16GB, 1TB + SSD 1TB, AMD Radeon RX6600XT 8GB, Free DOS (altex.ro)

Now to the question/issue.
I noticed in almost all games: Warzone , Valheim, Destiny 2, Hunt: Showdown, Cyberpunk 2077 there are some stutters while de framerate is relatively high around 100-120 depending on the title.
I tried fiddling with the graphic settings with no success.
I tried limiting the FPS in all games to 90 + Low settings, so I can rule out FPS drops as the perceived stutter.
I tried updating the BIOS to the latest version I found 2403 for this Mobo
I tried overclocking the CPU on all cores to 4.5Ghz which didn't help and also the CPU was running too hot with the stock AMD Cooler Wraith 90 Degrees, so I put everything back on default.
I have 2 D.O.C.P profiles for the RAM 3000MHZ and 3200Mhz with different Latencies with no perceived improvement on the stutters.
Also tried to fiddle/optimize graphics settings in the AMD driver
L.E. I don't think also the system is thermal throttling since on default settings GPU highest was 71 Degrees and CPU7 74 Degrees

At this point I'm out of ideas on how to fix/determine what are the cause of those stutters.
Only ideas I have now is to buy a new pack of RAM Dual channel since I know that single channel dimm is not ideal ( but that's what the prebuilt system came with)
Second thought is that the CPU being APU and having 16MB L3 Cache might be the issue but I kinda doubt it.

So in other words if somebody can help me in determining where is the issue, I would send an actual beer.

Also Happy New Year 😀

You will need to identify the PSU by looking at the stickered side of the PSU, which from the site's listing should be fairly simple to do with a tempered glass side panel.

If you're on Windows 10, what version(not edition) of the OS are you on? If you're indeed on 2403, you have two more BIOS updates pending. As for your system, you should've been given a 650W reliably built PSU to power the entire system while having an RX6600XT in there, that's what I think is the cause of your stutterslack of power to all components.

Hello Lutfij,

Thanks for the quick reply, Windows 10 Version is 21H2.
I checked now the Asus Driver page you linked and indeed I am missing the latest BIOS, I didn't check their site at that time, their software Armoury Crate listed 2403 as the latest BIOS so that's what I flashed. I'll go ahead today and flash the new 2423.
For the PSU I went under the desk now and the only information that is visible without pulling out the PSU is the brand which is nJoy.
I also thought of the PSU being the bottleneck, but I came across a website Power Supply Calculator - PSU Calculator | OuterVision and it returned a minimum of 500W PSU while the system accounting the fans and everything under load it would pull 460W~. Although I can't say I 100% trust the website but I used it just to give me an idea.

I am under no illusion that I will need to swap the PSU to a reliable one either way, I know that on the prebuilt system they cheap out on the PSU.

But thanks for the insight.

I will add in the shopping cart a PSU and Dual Channel Dimms,

Power Supply calculators are mostly just garbage.
Njoy has 4 different 500 watt power supplies listed on their web page none of them can are actually rated to put out 500 watts on the 12 volt rail.

For your problem the single stick of memory would be the first place I would start.
AMD processors need fast dual channel memory.

That's bad. This one? https://altex.ro/sursa-de-alimentare-njoy-titan-500-500w-80-plus-bronze/cpd/CSATYTAN500/ Please replace it for https://altex.ro/sursa-de-alimentare-msi-mpg-a650gf-650w-140mm-80-plus-gold/cpd/CSAMPGA650GF/

Thank you for the help guys, now that I got more info and confirmation on some of my assumptions I am relieved.

I'll wait for the pay check and upgrade the system, I am not sure what answer to mark as best, I'll close my eyes and let fate decide.
