Hello, your recent upgrade from an I5 7600K to a Ryzen 5 7600x seems smooth overall. The long boot times and the ez debug LEDs indicating CPU and RAM activity are common after such upgrades. Once the PC powers on normally, it boots into Windows without issues. This behavior is typical and not unusual. Others have reported similar experiences with MSI MPG B650i Edge and various BIOS versions. A short clip will illustrate what you're seeing.

Uncertain about MSI motherboards, but on my friend's Asrock x670e Steel Legend the debug lights also illuminate during boot. We also inquired and reached out to Asrock for confirmation. They confirmed it’s typical as long as the lights turn off after the system completes POSTing without problems. I think they mentioned it’s part of the DDR5 error-checking process.

I discovered a discussion on AMD forums about DDR5 training, which seems to occur during nearly every boot when EXPO is active (as in my setup). The "Memory context restore" appears to reduce the necessity for memory training but might cause boot instability. I plan to experiment with the configuration (EXPO + Memory context restore enabled) for a short period to assess stability, or revert to Jedec speed until a BIOS update resolves the issue.

I won't wait long; one boot worked then two failed with Expo plus memory restoration turned on. It's really unstable, so I'm disabling Expo right now until a solution is available.

Does "failed" refer to the PC never starting at all? It may take a few minutes, up to 15. The latest BIOS AGESA can lead to slow startup on many systems. If EXPO doesn’t boot, the RAM might be defective—testing it would be wise. It’s better to understand now and return it than to handle the manufacturer’s warranty later.

The PC displayed a blue screen before entering the login prompt. I plan to check the RAM, but I’ll skip the training since the system runs smoothly even after a lengthy startup.

Discussing the thread highlights that the v115 BIOS performs the quickest postings. However, entering BIOS seems more challenging until a clean shutdown occurs after training. It appears they are urgently seeking a new stable BIOS release. Avoid trying higher RAM speeds now—they will cause excessive delays during POST.
