Pin placement on motherboard may be distorted.
Hey everyone, I bought a used 2011 socket Supermicro board from eBay. It came well wrapped and had the socket protectors, but during my check I noticed bent pins (photo attached). After installing CPUs and testing the machine, it worked fine until it would start up but then hang at 2F due to memory issues. Memory tests on another machine showed everything normal. The board would shut down by itself while stuck at 2F and wouldn’t power back on. I removed extra parts like the PCI-E USB3 card, which fixed the problem and let me access BIOS. I saw all memory detected and CPUs displayed correctly. After exiting BIOS, I booted into Unraid for a few seconds to a minute, then it powered off again and wouldn’t restart. I changed the power cable and it worked, but it still powers off after a short time. I tried my spare PSU too—it had the same problems. Maybe the bent pins are causing the issue? Anyone familiar with this type of problem has suggestions? I don’t want to bother the seller if it’s not a motherboard fault. What else should I try?
It’s highly probable the bent pins are causing the issue. To reassure yourself about your diagnosis, you might check a pin diagram or map to see if those bent pins affect memory performance. Based on what you’re observing, it would be wise to reach out to the seller.
