This setup doesn’t start up with both RAM sticks installed, but it functions when only one is present.

Hi, your new setup is coming together. The specs match what you have: MSI B850, Ryzen 5 7600X, Gigabyte Eagle 4060Ti, Corsair Vengeance DDR5, and 16GB RAM. Everything seems to be powering up normally until the first boot. You noticed the fans running, lights on, but no display and red/orange LEDs on the board. The manual says red means CPU issue, but you suspect a RAM problem since there’s no orange. After swapping RAM sticks, it works fine—BIOS shows up correctly. Trying another stick with one RAM still shows the same red/orange LEDs. On booting with just one RAM, a yellow LED appears briefly before disappearing and the system starts normally. The orange LED’s meaning isn’t clear now. You’re considering whether the issue is with the motherboard or RAM, and wondering if you should replace the RAM sticks. Given that everything is new and you’ve already installed one working stick, it might be a compatibility or configuration problem rather than faulty hardware. If you want to ensure stability, you could test with a different RAM model or consult MSI support for XMP vs Expo support.
Replace the CPU, as it may have a faulty connection leading to one of the slots malfunctioning.
Check your BIOS version. With DDR5 RAM, newer BIOS updates can resolve timing problems and improve compatibility with certain RAM modules. Also, verify if XMP/EXPO is activated—turning it off might help you notice any changes.
Uncertain about the BIOS version, I’ll check later. Regarding XMP, yes. I have two sticks in both B1 and B2 channels, but it didn’t boot initially (I used A-XMP). After trying again with one RAM in B2 and it worked, I turned off A-XMP and added another RAM in B1, which resolved the issue. Now I’m sticking with that setup.
