Asus ProArt X870e No Post, No Boot 9800x3D
I've just build a new setup with brand new parts. When I booted PC doesnt post with CPU led staying red without blinking. The parts: CPU: 9800x3d RAM: Corsair Vengence 2x32 6000mhz (CMK64GX5M2B6000Z30) Mobo: Asus Proart x870e WIFI PSU: Corsair RME850 Edit: I’ve checked the ram slots and found one discrepancy though not sure if it is a problem. RAM slots So far tried: 1 Stick ram. Didnt solved it. I've tried new kits still no post. Also tried new CPU but still same issue. BIOS update to the latest. Didnt solved it. CMOS reset with the other stick of the kit. Didnt solved it. Reseated CPU. Didnt solved it but CPU led went off and VGA light went on, then rebooted itself and stayed on CPU led red again. Never able to reproduce this again. Removed GPU, nvme and other peripherals. Didnt solved it. Checked CPU pins and they are all fine no out of shape pins. Checked all power connections, they are all connectted correctly. I am at the dark at this point. Should I try with a new RAM kit? or Is this a dead CPU I'm not sure. If someone had similar experience or knowledge, a help would much appreciated!
You've completed several troubleshooting actions to eliminate common issues. The CPU appears to have an integrated graphics unit, so verify if connecting the monitor via HDMI and Thunderbolt ports resolves the problem. The CPU debug indicator might point to a CPU or motherboard fault, while the VGA light could indicate issues with the CPU, board, or RAM. Re-seat all connectors—especially the 24-pin motherboard connector—and ensure the PSU power switch is correctly aligned on the right pins. Also inspect the front-panel connectors. If none of these steps work, consider testing your components in another system to identify the faulty part. Good luck!
There are some changes I've noticed. I was able to enter BIOS without using the GPU and NVMe was installed. But when I restart the system, it takes 4-5 minutes to reach BIOS and the USB keyboard isn't recognized. If I install an NVMe drive (tried all three slots) or plug a new keyboard in again, the system freezes at the CPU LED and doesn't respond. I believe the motherboard is the issue. Also, the PSU connections look correct. Throughout these steps, I haven't touched or moved the case or power cables.
This might be typical. Training memory requires significant time with DDR5 RAM. You might want to reinstall the newest BIOS a few times (it can sometimes work), but I believe you're correct about the motherboard. If you purchased from a shop, do you still have the option to return or exchange? That should be the quickest method to get another board. If you bought online, you can't contact the seller and must follow their process. Good luck!
Isn't this just the first time? It seemed identical across all successful posts too. Yeah, I also tried flashing it multiple times but didn’t fix it. I managed to resolve it through Amazon, so I’ll return and order a new one. If it doesn’t work with a different motherboard, I assume it’s either a PSU or a skill issue now. Thanks! I’ll update once I have the new one, so others can follow my troubleshooting steps if needed.
There is a BIOS setting that keeps previous training data. It might be turned off or require a full boot to activate. The label seems to refer to "Recall Memory Training," though the exact name can differ by manufacturer. They generally have a solid reputation for respecting return policies. Have a great day!
CONCLUSION: The issue was the motherboard. I swapped it out and now everything functions properly.
