New to overclocking, followed a video guide by MSI on YouTube. As I increase the overclock, the performance numbers get worse. HWinfo shows me that during stress tests, the clock is dropping to 800MHz periodically. Is there a setting within my BIOS which is throttling performance? Why is performance so much worse with the OC? Full info below.
PC specs:
- CPU Intel i5-9600k 3.7GHz with corsair h60i cooler
- MSI MPG Z390I GAMING EDGE AC mini-ITX
- 16GB Corsair DDR4 Vengeance 2666MHz
- Gigabyte 1060 6GB
- ADATA SX900 SSD
- Windows 10
Everything on default – original benchmark scores:
- PassMark 13428
- CPU-Z 513 (single thread); 2796 (multi thread)
- when running benchmark at stock, the CPU clock would drop to 3.7GHz when at 100% load, but idle at 4.6GHz (the turbo boost speed). Is this normal? Surely the clock should increase during load unless there is some kind of throttle going on?
Overclocking to 4.4GHz (although I understand this is below the turbo boost of 9600k)
- PassMark 4976
- CPU-Z 443 (single thread); 2473 (multi thread)
Overclock to 4.9GHz
- Passmark 4441
- During the benchmark test, clock would drop to 800MHz with temps of less than 50 degrees

Here are the changes I made to my BIOS (images of bios in link below)
- OC explore mode - expert
- CPU ratio - 49
- CPU Ratio mode - Fixed mode
- CPU ration offset when running AVX - -3
- VCORE - 1.32v
- CPU SA and CPU IO - 1.2v
- XMP enabled
- CPU loadline calibration Control - MODE 4
- Intel C-state disabled
