Hey all! I've had this PC for a few months now, and I noticed that it under-performs in a lot of stuff that I throw at it. Not by a huge margin, but enough that I notice it under certain circumstances. It is also remarkably consistent in it's under-performing. Does anyone have any advice?

I have also watched benchmarks of games that I play with the same specs and I have noticed a similar disparity in framerate while using the same settings. Things I have tried: Completely wiping drivers and reinstalling them (both GPU and Chipset) Monitoring temps (CPU never gets over 80c, GPU never gets over 75c) Completely fresh Windows reinstall (from USB drive) Confirming BIOS settings (XMP/DOCP on, etc) BIOS update Making sure no programs are running in background hogging performance De-bloating and optimizing Windows for performance Possible theories: Motherboard is a bit older in terms of chipset and PCIe My CPU supports B550M, whereas my motherboard is B450M My GPU supports PCIe 4.0, whereas my motherboard can only do PCIe 3.0 speeds Windows 11 vs Windows 10 I am running 11 which may yield worse performance than 10 I am just unlucky This would suck if it's true, but maybe my CPU and GPU are just slightly worse than average and it's something I gotta deal with If you made it this far I really appreciate it!
Are the RAM slots correctly installed? The data indicates both the CPU and GPU are struggling on their own. This isn’t typical of PCIe or chipset problems affecting the CPU. Seems the RAM is the main factor in most tests. Could you share CPU-Z details for your RAM setup? Also, do your 3DMark scores reflect what you’re seeing?
The write is clear and straightforward. It highlights a potential bottleneck with CPU and RAM performance, suggesting checks like disabling fast boot settings or clearing CMOS. It also offers tips on overclocking, timing adjustments, and testing stability. The advice emphasizes thorough testing for long-term reliability and mentions specific configurations that could improve scores.
There are several factors that might lead to such issues, making the hail mary troubleshooting approach sensible. Install HWInfo64, switch it to "sensors only" mode, and log data during each benchmark run using the provided button in the bottom right. This will compile all sensor information—temperatures, clock speeds, usage stats, etc.—into a single file for easy analysis with tools like GenericLogViewer. For 3DMark, capture both CPU and GPU results since performance can vary between components. It’s likely a hardware issue such as power throttling, but detailed sensor data will clarify the cause before jumping to conclusions.
I own four 8GB memory modules, filling all four RAM slots on my motherboard. Here’s the link with screenshots of a 3DMark test and my CPU-Z data: https://imgur.com/a/7wCjGth My CPU temperatures peak at 81°C during a Cinebench session and there’s no sign of thermal throttling.
I think my RAM is using dual channel. I'm still learning about RAM timings, so I'm looking into this now. So far, I've discovered that my memory die is Hynix 8Gbit AFR. That might be helpful! This link shows screenshots of the CPU-Z memory section if you want to verify speeds or DC values: https://imgur.com/a/7wCjGth I have PBO turned on, but I haven't adjusted anything beyond that (I don't even notice a curve setting in my BIOS). I also have 4G decoding and Resizable BAR enabled. I lowered my BIOS to 3810, but it hasn't noticeably changed the scores (same with the Windows options)
I downloaded the two CSV datasets from HWInfo. One reflects a Cinebench benchmark and the other shows a 3DMark result. I also gathered the temperature images during the 3DMark test via Screenshot link. The Cinebench scores stayed near 81°C throughout the session.
RAM status appears normal and could help reduce bank cycle time, though managing four DIMMS makes adjustments tricky. Have you attempted to turn off PBO for comparison? It's interesting that no noticeable CPU speed boost showed up after lowering the BIOS and disabling Windows security. That seems unexpected—there should have been a small improvement due to reduced performance penalties from security features.
Reviewing the data shows the GPU performance is close to average, whereas the CPU lags about 700 points behind. This suggests a potential CPU or BIOS problem. Examining the Cinebench CSV reveals the effective clock speed is significantly reduced, a common issue called "clock stretching." It makes sense since higher CPU usage typically slows performance more noticeably. This behavior often stems from system instability. You might want to check for voltage variations, reset the CMOS, avoid modifying BIOS settings (like XMP or PBO), and see if it improves.
