Your problem is not with your memory. It's with your task/resource manager.
Based on the HWinfo information, your memory is running at 3000mhz with timings of 16-16-16-35, which should be totally normal. It's not unusual for Windows to misreport or not report hardware at all. I'd stick to third party utilities like HWinfo, CPU-Z, Core Temp and Ryzen master for sensor reporting.
