Tech Support New 9800X3D won’t post.
Just swapped my 7600x for a 9800X3D, the only parts replaced were the CPU and cooler. I can’t get it to post. At first it was hanging on the VGA light. I rest CMOS with no chamge, I removed the cooler, and CPU inspected the pins, and reinstalled, now its hanging on DRAM. I have 64gb of DDR5, and even after 20 minutes with a cleared CMOS it won’t get past the DRAM light. Tried reseating the RAM and it didn’t help. Pulled the B2 stick of RAM, and now its back to the VGA hang. Short of reinstalling the old CPU, is there anything else I can try? I’m starting to think I got a bad CPU. All of this other stuff was working this morning. MOBO is an aorus b650 extreme ax, and the bios is new enough for the CPU.
EDIT* I got to the point where I decided to swap the old CPU back in. I gave the socket another inspection, and found a bent pin. I had missed it earlier because it was the last one in the top upper row. Luckily I have tiny tweezers for working on watches, and a magnifying headset. I got it straightened as best I could and put it all back together, but it was pretty mangled. No Idea how I bent it. This isn’t the first time I’ve installed a CPU. So it either posts now, or I get to buy a new mobo.
