Load on the CPU isn't consistent? (AM5)
Load on the CPU isn't consistent? (AM5)
In short, my processor isn’t always at full capacity during heavy tasks or stress tests. I notice performance drops when things rely on the CPU. Here are my current details: ASUS TUF Gaming B650-PLUS WIFI Ryzen 5 7600X3D, RX 6700XT, 12GB by Powercolor, 32GB G.SKILL 6000MHZ DDR5 RAM. The power supply is a 750W gold unit from a reputable brand, not a budget Chinese model. I’ve dealt with similar problems before on an AM4 setup, making minor adjustments to get stability. Now I’m facing the same issue on an AM5 system with a brand-new BIOS, and I’m completely unfamiliar with it. My power consumption stays low under load—around 70W, never exceeding that. The CPU stays cool, rarely above 60°C. I’ve tried tweaking settings, resetting BIOS, enabling unnecessary options, and even reset the system, but nothing helps. I’ll include screenshots of Task Manager and CPU load during stress tests. My system also experiences random stutters during non-test tasks like video compression, editing, or playing Beam.NG, where the CPU struggles to keep up. Outside of Prime95 and Cinebench, these issues happen during everyday activities. I’m curious—could this be a Windows-specific problem or something related to power delivery?
That doesn't mean it isn't crap though, plenty of major companies have made 750W 80+ Gold units that do a better job stopping a door than they do supplying power. Take the side panel off and see if you can figure out the model and make sure it's actually decent first, since a bad PSU can cause weird issues like this. Also, is this a new Windows install? I'm just trying to think of things that are the same between both systems to figure out what is the cause of this, and your old Windows install could just be borked. Assuming this is a clean Windows install and you can verify that your PSU is actually decent, these would be my next steps. First, change the BIOS revision, there are a few floating out there that cause weird power behaviour like this. Newer isn't always better either, so even if you are on the newest revision it might be worth dropping back to an older version to see. If that doesn't do it though, there's a lot of other things that can cause this, and I'd recommend just going for the hail mary approach. Download HWInfo, launch it in Sensors Only mode, and hit the button in the bottom right corner that looks like a piece of paper with a plus on it. This will create a log file of all the sensors in the system, so if there is something misbehaving that causes this, it'll hopefully show up in there. Run Cinebench or do something otherwise intensive and send the resulting CSV file so we can try to parse it and find the issue.
It's a MB750G power supply, just recalled. - The Windows update is roughly two months old? It was recently reinstalled. - I'm a bit hesitant about downgrading, never done something like that before. - I'll try it when I have more time; I'm currently occupied. Thanks for your assistance.
It's the same procedure as a BIOS upgrade, except the version number decreases rather than increases. It's fairly typical for the newest release to have some issues (my motherboard, the Z690 Unify X, for example, experienced CPU cache overclocking problems in the latest BIOS version, meaning you had to use a particular BIOS release for overclocking).
