StoreMI Ryzen Master
AMD StoreMI Technology AMD Ryzen™ Master Utility
SSDs are fast, but expensive, and offer minimal capacity. Mechanical hard drives boast large capacity for a low price, but are much slower than an SSD. AMD StoreMI technology “combines” these two types of storage into a single drive and automatically moves the data you access the most to the SSD. Every AMD Ryzen™ processor is multiplier-unlocked from the factory, so you can personalize performance to your taste. AMD provides the AMD Ryzen™ Master utility to access this powerful advantage.

This is an expensive cpu but runs well if properly cooled. Average temp is a little on the high side due to a small surface area on the chip, expect avg temp of 65-84c as normal. Might want to have a good extractor fan on your case at the top backplate to exhaust the warm air.

Simple, if you need power buy this switched from Intel and never go back, i love it 30C in idle and 60C load stock speed with msi meg x570 Ace and H115i, Excelent AMD.
