Windows 10: Core Speed Limit

Hi, i've been doing research all around the Internet and none of them fixed my problem.I have problem with Core Speed Limit. With my R5 4500 CPU, Asrock B550M Steel Legend Motherboard, and with Cooling MSI MAG Coreliquid C240.My max Speed is 4.1 Ghz and somehow can boost to 4.2 Ghz on normal settings. I tried to OC with 4.45 Ghz and 1.4V. Running good with R23, daily use. But when i have use it for a week. I look at the AMD Overlay peformance & task manager it will boost to 3.9 Ghz even it use for Stress CPU Benchmark. I always pay attention to Temprature of my Hardware and never get above

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Step-by step overclocking in Wattman
Fan speeds
Power limit
Temp limit
Voltages
Core speeds
Memory speeds

 

Query re dual/quad core speeds.

The default speed of every core is the same as the others - 2.40GHz . There are speed steps which allow the processor to run at lower speed and thus save power .

 

Speed limit wrong.

The speed limit is listed at 55 in Ohio on I-77 between Portage Rd. and just north of Fulton Rd. It changed to 65 several years ago.
