DRAM red light, will not post on Gigabyte B850 Gaming X wifi6e

Hardware Hub Build a PC

Building a new pc for a family member and having an issue. The desktop is built, but upon powering it up, we get stuck on a DRAM red light and it will not/has not posted. System is a Ryzen 7 9800X3D, Gigabyte B850 Gaming X, and 32GB of Corsair Vengeance DDR5 RAM. All purchased at a local microcenter as a bundle.

Basic troubleshooting that I have already done includes: confirming appropriate RAM slots, using 1 stick in each independently. Letting it sit powered on in the event of RAM training (gave it 20-30 minutes). Ensured all power connections are appropriate and secure. Re-seat the GPU and RAM, ensure m2 drive is seated appropriately.

Any thoughts where to go next?

Definitely following this post. Even created an account to comment. I am having the same exact issue and can boot into windows after turning it on a second time from initial boot.

I just did the one ram stick solution and swapped between both on A2… one of the sticks is bad. One stick booted successfully with multiple cmos clearings and the other did not. Exchanging at microcenter tomorrow.

I have attempted each RAM stick individually without success, the plan is tomorrow to still exchange at microcenter. Do you have the same RAM?

I believe so yes, I have…

Exchange complete and it started with no issues. Interesting case that we had defective ram from the start. Hope you have the same results!

Exchanged ram this morning, works perfectly now. Poor quality assurance it seems. Glad you got yours on!

I did a client build with 7800X3D with corsair vengeance 64000 memory, and had one of 32GB kits (both sticks in the kit) cause posting issues 3 months later. Both sticks failed memtest immediately with XMP/XPO off. It was beyond the exchange window, but within warranty and corsair exchanged it no problem. The last couple years I have seen allot more RAM and CPU failures than I ever have in 25 years doing repair/IT.

As I was driving back from the exchange, I was concerned that this may not be the issue and is was something else. I was happily surprised when it worked! The build was for a family member so it also made my phone stop pinging due to “when can you help me” texts.
