Error code b7 detected on ASUS z10pe-d16 WS device
Hello, welcome back as a long-time viewer. I’m facing some challenges with my rig. Here are the details: I have an ASUS Z10 P-E-D16 motherboard with a 2x M.2 slot, ECC RAM, an e5-2690 v3 64GB DDR4 2666 RAM (8x8), and a 1200W PSU. The issue is that error code B7 appears. Removing all RAM except one lets me post successfully, but reseating it causes problems. If I leave the PC overnight, the same error recurs. I’ve re-seated the CPUs, tried various BIOS settings, and updated my BIOS. I know my CPUs are rated for 2133 MHz, so this should allow the 2666 RAM to run at that speed. ASUS error B7 means a configuration reset. Any advice or suggestions would be helpful!
hey, thanks for the response. I took your advice and flashed the firmware, I also changed the CMOS battery as apparently this powers the NVRAM (whatever the hell that is!). I did this while the error was still occuring (before reseating), and it posted!!! I'll see if it misbehaves again tonight, but thank you!!!!
I went out to the dog and came back with the same issue again. I tried adjusting the RAM slots once more, thinking I might have caused a problem. When I tested it on CPU1, the error appeared in the first loop. On CPU2, the error showed up during the second cycle of the B codes. I’m assuming the motherboard would handle it that way. It’s interesting that after removing it, running Cinebench gave me 200 points better with 7 dimms. I’ll keep an eye on the situation and ask for any suggestions if someone has them!
Hello, the issue is the same. System initialization for b7 is not working. Please check and fix it. Thank you.
I received an Asus Z10 server from a client at my service center. The issue was the b7 error code. Upon inspecting the motherboard, I discovered several damaged pins in the CPU socket 1. I replaced those pins using my IR station, and the board functioned correctly afterward.
This topic often comes up in discussions but rarely gets fixed properly. I faced the same problem, which caused me to question every part of the setup until I found the root cause. It turns out the board loads drivers for hardware during POST, storing them in a RAM module powered by the CMOS battery. When the battery voltage drops, problems start occurring. The fix was swapping the battery—it was expensive and nearly cost me my system, which I needed to keep reliable for rendering. It has worked well for about six months now. Let me know if this helps.
Hey there. I saw you're facing the same problem with your Chinese x99 motherboard and E5-2696 v3. It sounds like a tough situation. You had two 16GB sticks at 2133 MHz with ECC memory, but after a brief power surge without a UPS, your system restarted but didn't boot properly—only the sound came on. Anyone have any tips or solutions?
