Hey everyone! I'm in need of some guidance with my AM5 build. I constructed two identical PCs using the following components: Ryzen 7 9700X, ASUS Prime RTX 5070, G-Skill 2x16 GB DDR5-6000 CL30, ASUS Prime B850-Plus Wi-Fi with the latest BIOS, and a Lexar NM790 SSD 2TB. While PC #1 works flawlessly with EXPO enabled, PC #2 has been quite problematic. When EXPO is ON, it experiences long boot times of 3-5 minutes, random reboots during Windows loading and gaming, and occasional blue screens related to memory. With EXPO OFF (running at 4800 MT/s), it doesn't reboot, but about 1 in 5 boots stalls on a black screen for 3-5 minutes before the system restarts itself and finally gets to Windows. I've updated the BIOS, cleared the CMOS, and double-checked all connections, but the long black-screen boot continues to happen intermittently, even with EXPO disabled. Has anyone faced this issue with AM5 boards? Oh, and the RAM is on the motherboard's QVL. I would really appreciate any help!

Check if you have memory context restore enabled. While that can help with memory training slowdowns, 3-5 minutes boot time is still pretty unusual. I think there might be another issue at play.
It sounds like you might be dealing with bad RAM modules. Have you tried running just one stick at a time and doing a memory test? That could help narrow down the issue.
