Does XMP perform better than a turbo-enhanced processor?
I understand you're wondering if enabling XMP will improve your system's performance. It seems like your CPU speed drops from 3.2GHz to 2.8GHz when you turn it on, and your RAM is supposed to run at a higher frequency. Your motherboard model is MSI - MPG Z390 Gaming Plus, with an i5 8400 processor at 2.8GHz, a GPU of EVGA 2060 at 6GB, and RAM at 2133Mhz. You're using Windows 10 64-bit.
Your CPU is intended to increase its speed to 4.0GHz when using a single core, with higher cores running at a slower rate. XMP doesn't prevent turbo boost. It's possible this information came from an incorrect source. There could be exceptions on some motherboards, but it's not the standard behavior.
Your CPU is intended to increase its speed to 4.0GHz (on one core, with a gradual slowdown on more cores). XMP doesn't prevent turbo boost. It's possible you heard something incorrect; there could be an issue with certain motherboards, but it's not the usual case.
The best approach is to check if the issue occurs on your motherboard. I wouldn't want the 2.8GHz i5-8400 to have Turbo turned off. If it does, you might also consider manually setting the XMP values instead of just enabling them.
