Problem with Ryzen 5 7500f PBO?
Problem with Ryzen 5 7500f PBO?
Hello,
I recently upgraded my old PC with some new components:
- Ryzen 5 7500F
- ASUS RogStrix B650E gaming Wi-Fi
- Lexar Ares DDR5 32GB 6400MHz CL32
I plan to enhance performance slightly using PBO settings. My processor runs fine with -30 all cores negative, yet I still receive a base boost clock of 5050 MHz.
Here is the image from my post:

The BIOS shows something like "CPU Fused Boost Clock Limit." I’m curious about its meaning and how to adjust it. It seems the value matches the maximum CPU clock. For more details, my BIOS is up to date (version 1813), and I’m using an old PSU – Seasonic Focus Gold 650W with just one EPS power cable connected.
Please let me know if you have any suggestions!
Best regards
Hey there,
I think you're attempting too many changes at once. It would be better if we focused on one thing first. We need to understand how your system is currently performing. Please reset your BIOS to the default settings and run benchmarks for both CPU and GPU at stock levels. This will give us a solid baseline. Use Cinebench R23 for the CPU and Superposition or 3d Mark Firestrike for the GPU, taking note of the scores and averaging three runs each. Once you have that, we can move on to adjusting your overclocking settings. Let me know how it goes?
Here are the benchmark results you provided:
CinebenchR23 - 14k
3d Mark Firestrike - 29.5k
You mentioned you ran three tests of each and used the average.
GPU - RTX 4060Ti 8GB
OS - Windows 11 Pro
AiO - Arctic liquid freezer II 360
Unfortunately, performance remains consistent, meaning the stock BIOS with DOCPII profile versus PBO ON and DOCPII profile. The CPU clock is still fixed at 5050MHz.
At this point, the only method I know to improve the CPU is using Ryzen Master with the "Auto OC" profile, which raises the clock to 5150Mhz, but this also changes PPT, TDC, and EDC to 1000. I’m not sure if this works well for my PC.
Also, anyone know what the CPU Fused Boost Clock Limit means and how to disable it?
Well fylyp
I purchased a similar CPU and managed to achieve a boost of up to 5050 mhz by setting it to -30. This didn’t seem like an issue, or I might have overlooked something. Without undervolting, the boost was lower, below 5000 mhz, which is somewhat unusual (less power usage but higher clock speed). Also, I set the platform limit to 75c, but generally newer CPUs exceed 72c – I’ve double-checked using CinebenchR23 (with Arctic freezer A35). Currently, I also looked at my BIOS PBO settings on MSI b650 Gaming plus and found no "CPU Fused Boost Clock Limit" option. Personally, I’m very satisfied with this CPU. It replaced my i7 4790k, which was the best CPU I’ve ever owned. Hope it continues to work well for a long time.
Best.
