Is the CPU performing poorly in benchmark tests?
Is the CPU performing poorly in benchmark tests?
Hello everyone, my Ryzen 7 9800 X3D CPU is not doing well in benchmarks. It only managed 1045 points on Cinebench 2024 and isn’t reaching the expected 800 points from CPU-Z. Something strange caught my attention: my temperatures never exceed 62°C during full load (98-100% usage).
Recently, I changed my GPU and had to update my BIOS; otherwise, I was stuck with a problem where my RTX 4080 wasn’t sending the video signal. In games, I still get good FPS and performance isn’t an issue, but there’s something off.
After updating the BIOS, I loaded the "default optimized settings." Maybe I’m missing some configuration. I can’t recall my previous Cinebench 2024 score, but I remember temperatures often staying above 70°C during heavy tasks or other demanding activities, and now they never go past 60°C. Here are my specs:
- Gigabyte B650M Gaming Wi-Fi (rev 1.2) with BIOS F35 (3D mode and Eco Mode disabled)
- AMD Ryzen 7 9800X3D
- Corsair Dominator Platinum RGB DDR5 32GB (Dual Channel) - EXPO enabled
- Corsair RM1000e PSU
I also checked my BIOS settings; PBO was set to Auto, but when I switched to "Motherboard" mode, the values changed:
- PPT Limit [mW] – 90000
- TDC Limit [mA] – 100000
- EDC Limit [mA] – 120000
These limits seem low, especially for PPT. I’m not sure what the correct numbers should be—maybe they should be 162000 (something I found online).
In my BIOS, there’s an option to enable PBO Enhancement with various levels. I might want to try those settings.
I also attached a screenshot of HWmonitor while running Cinebench 2024:

Thanks!
I recently changed my GPU and needed to update the BIOS; otherwise, I encountered an issue where my RTX 4080 wasn’t sending the video signal. In games, I’m still achieving solid FPS and performance isn’t an issue, but there’s something off.
I’m following these steps: flash the BIOS to version F36h, reset CMOS, ensure UEFI is active, along with Secure Boot, fTPM, Fast Boot, and AMD’s E.X.P.O.
On another note, could you share a link to the RAM kit you’re using? How do you cool your processor? What is the case model and make?
Since you’re moving to the RTX 4080, what GPU were you using before? Did you use DDU to uninstall all GPU drivers (Intel, AMD, Nvidia) in Safe Mode, then restart and install the newest driver from Nvidia’s support site via an elevated command—right-click the installer and select Run as Administrator.
If I were you, I’d have chosen a different motherboard if I knew I was planning to get an A9800X3D. Something with a stronger VRM setup, like an MSI B650 Mortar, would be better if you prefer the B650 chipset. A B850 Mortar would still be a solid all-rounder.
I was thinking about upgrading the motherboard to a more powerful chipset, but it’s quite costly in my country and I’m really struggling to afford something better at the moment. The B650 performed well before the BIOS update, except for the GPU that didn’t have video output. I believe the "Load optimized default" setting might have affected some configurations.
Before the RTX 4080, I used a RTX 4070 and even a RTX 3070. Yes, I had to uninstall all drivers and install the latest NVIDIA and AMD chipset drivers. While gaming, I’m still getting decent FPS without any stuttering or other problems, though benchmarks are not great.
For RAM, I’m using the memory kit (2x 16GB) from the Corsair website. I also kept EXPO enabled in BIOS, except for the version with high bandwidth support. I’m not sure if it should be turned on as well.
In terms of cooling, I’m using a Gigabyte Aorus Waterforce II 240. Before the BIOS update, I could maintain temperatures up to around 80°C during those tests.
I suspect my PC is outdated and, unfortunately, because of this B650, overclocked features are disabled. I can’t use Ryzen Master to fix them automatically. At least I can adjust some settings in BIOS, but I’m not sure what the right values should be.
Thanks for your help!
The optimal setting for AMD's AM5 platform is DDR5-6000MHz or DDR5-6000MT/s. You might consider using DDR5-6400MHz or DDR5-6400MT/s instead. Your existing RAM is DDR5-5200MHz or DDR5-5200MT/s, leaving room for improvement.
I'm unsure if the BIOS update should have been applied.
Ryzen Master's Curve Optimizer appeared to be active before the BIOS update.
Are you certain you're not mixing up single-core and multi-core evaluations? It appears you're only executing single-core tests at the moment, which doesn't fully reflect your CPU's performance and can cause the chip to overheat. My Ryzen 9800X3D barely hits around 50c on the Cinebench single-core test but consistently surpasses 80c on the multi-core version. Also, consider what applications are running in the background during those tests. Closing all background programs often leads to a much higher score on CPUz compared to when other software like iCUE, MSI Afterburner, Logitech Hub or Steam is active. The scores you see online are typically achieved with systems that run only the benchmark without any additional tasks.
Sorry, I didn't notice the MTs on the Corsair website, mine is 6000 MT/s.
By the way, I just ran a test now. I turned on the PBO Enhancement for an 80 level 2 and achieved 1220 points on Cinebench 2024, but I'm still capped at 90W. The temperatures are rising now up to 65ºC, which is still a bit concerning for a stress test.
Anyway, turning on PBO Enhancement doesn't seem to affect the PBO values in Advanced Settings.
I'm considering adjusting the PBO numbers manually, but I'm unsure which value to use.
Edit: Forgot to mention Ryzen Master, but it doesn't work with this motherboard as overclock functions are disabled. Although, I can modify some PBO settings in the BIOS.
