It is like a BIOS compatibility issue might be at play, especially if the flashback light didn?™t come on. You might want to double-check that the BIOS update process was done correctly?”sometimes using a smaller USB drive and formatting it to FAT32 helps. Also, trying a single stick of RAM in different slots could help rule out memory issues https://moonphasesoulmate.com/.]]> Wed, 26 Feb 2025 06:16:55 +0000 https://forum.asrock.com/forum_posts.asp?TID=99016&PID=183706&title=x870-not-posting-on-new-build#183706 https://forum.asrock.com/forum_posts.asp?TID=99016&PID=183341&title=x870-not-posting-on-new-build#183341 Author: djoeh

An update: Everything works now. I made a mistake in updating the BIOS, turns out that my parts don't work on version 3.11. I rolled back all the way to 3.06 and the system POSTS just fine, now dual booting Windows 11 and Ubuntu 24.04. Instead the issue was that my monitor didn't support input from my MB. With a new monitor things are working just fine. Hoping things continue to work, given that my DRAM isn't actually on the QVL list. I guess you never trust PCPartPicker to check QVL lists...]]> Tue, 25 Feb 2025 16:46:06 +0000 https://forum.asrock.com/forum_posts.asp?TID=99016&PID=183341&title=x870-not-posting-on-new-build#183341 https://forum.asrock.com/forum_posts.asp?TID=99016&PID=183260&title=x870-not-posting-on-new-build#183260 Author: djoeh

If it helps, the serial number of my G.Skill RAM is F5-5200J3636C16GX2-RS5W]]> Mon, 24 Feb 2025 17:40:36 +0000 https://forum.asrock.com/forum_posts.asp?TID=99016&PID=183260&title=x870-not-posting-on-new-build#183260 https://forum.asrock.com/forum_posts.asp?TID=99016&PID=183259&title=x870-not-posting-on-new-build#183259 Author: djoeh

I just made a new build with the X870 pro rs wifi MB, and the red+yellow lights come on to indicate a problem with the CPU or DRAM.
CPU: Ryzen 7 9700x
RAM: G.Skill DDR5 5200 16G installed in slot A2
PSU: be quiet! 1000W

MB is getting power in both 8-pin slots as well as the 24-pin slot.

I've tried flashing a new BIOS version in the hopes that might fix things but I wasn't able to confirm that I had done that correctly, as the flashback light did not come on as I pressed the button.

I'm wondering if there's any potential BIOS issues with the CPU I chose or if I'll have to go through some troubleshooting to see if my CPU or RAM is dead on arrival.]]> Mon, 24 Feb 2025 17:17:18 +0000 https://forum.asrock.com/forum_posts.asp?TID=99016&PID=183259&title=x870-not-posting-on-new-build#183259
