Support for Ryzen 5 1600X RAM.
The specs indicate the Ryzen 1600X supports up to 2667 MHz RAM. If you use more than that, the system may fail to boot. Your 3000 MHz RAM doesn’t work either, but it functions at 2400 MHz. The issue at 2667 MHz is likely due to outdated BIOS settings. Your motherboard uses B450M Pro 4 BIOS with P1.10 updates.
It should operate at a faster pace, though an update to the BIOS might be necessary. The advertised speed refers only to officially approved rates. I tested RAM at 3200MT/s with my R7 1700X after some BIOS upgrades. Ryzen had some initial issues with RAM compatibility. It seems ASRock advises sticking to BIOS version 3.5 for your CPU type. You can also review the QVL to confirm your RAM model works https://www.asrock.com/mb/AMD/B450m Pro4/#MemorySR
Here are some useful suggestions from Robert Hallock for boosting compatibility with 1st generation Ryzen processors.
Choose version 3.5 without hesitation. Make sure to install the driver referenced in the BIOS details first. The QVL offers limited insight since it only highlights tested features. Keep in mind that early Ryzen models were quite selective, making version 3.5 a solid choice for optimal performance.
When updating bios, the process generally takes a short amount of time, but you should be aware of potential risks like power outages or hardware damage.
Review the bios upgrade notes prior to proceeding. A previous bios release might be needed before installing earlier versions, and direct upgrades aren't always possible. Certain bios versions have removed support for older Ryzen models like the 1xxx to enable newer Ryzen 5xxx compatibility. AMD recently provided an AGESA package—a universal file included in all BIOSes—that supports every Ryzen chipset. However, at one point, some manufacturers had to discontinue support for certain Ryzen series (such as the 1xxx) to accommodate newer processors. A typical update usually finishes within 2 to 3 minutes.
The flashing process should be quick—just a few minutes at most. Unless your local power supply is very unreliable, you should be okay. The driver includes features beyond just GPU support; the GPU component isn’t applicable here since you don’t have an iGPU. True. I didn’t go through the full details.
