Gigabyte B550M DS3H AC R2 - fails to boot on AC power loss

Help me PCMR - this issue has me screwed. I've never seen anything like it before - and don't know what to do.

Troubleshooting steps: https://www.youtube.com/watch?v=CNWWvC_6zD8

The PC won't boot after AC power has been lost unless I reset the BIOS, then allow it to start from scratch again.

After configuring the BIOS (even just XMP + SVM), the PC will always boot fine until AC power is lost again. Then either the BIOS will reset or the PC will just fail to boot again.

  • CPU: Ryzen 5700G.
  • RAM: 4 x 32Gb CMK64GX4M2E3200C16 Vengeance LPX 64GB 3200MHz DDR4

An unconfigured Windows 11 install is on the NVMe SSD just for testing purposes.

CMOS battery measures at 3.1v - which seems to remove that avenue as a fault.

I have tried 1 DDR stick, 2, and 4 with no difference in behaviour.

Powering off via the switch on the Corsair power supply when Windows is booted will cause the same failure to boot problem - requiring a BIOS reset via the jumper to bring it back to life.

The board has been RMA'ed to Gigabyte - who sent it back saying No Fault Found.

Have tried BIOS versions F3 and F4a - Gigabyte sent it back to me with F3.

Help me PCMR - you're my only hope. What the hell am I missing?

Novated lease and redundancy

Hi all,

So I'm 1 year into a 3 year novated lease, and looks like I'm about to get a redundancy. Obviously, this means that I'll have to start covering the lease out of my 'savings' now that I won't have a salary to deduct things from.

What are any tips to minimise the impact of this?

Anything I should set up / change immediately to the lease setup?

FireCuda 510 crashes doing a long smartctl test.

Hi all,

I've been trying to talk to Seagate today to try and finally fix an issue with this drive that crashes every time I try to do a smartctl -t long /dev/nvme0n1 on it.

I've looked at the available firmware, and pulled the data using SeaChest, and I'm running STOSC017 - which seems to be the latest version listed on the Seagate site.

The full model number is ZP500GM30001 - and its a 500Gb NVMe drive.

I did lodge a case with Seagate about it, as it really looks like the controller crashes. The mainboards HDD light flashes ON 1s, OFF 1s and continues until the machine is powered off completely and back on again.

Just doing a reboot, the drive doesn't even get detected in the BIOS.

The BIOS based health check passes every time, and the drive seems to work perfectly otherwise - but every smart check crashes it.

Has anyone come across this? Is there a non-published firmware that might address this?
