Dear Beelink Support Team
I hope this message finds you well. I am writing to kindly request your assistance with a stability issue I have been experiencing on my SER6 PRO mini PC.
Hardware Information
Model: SER6 PRO
Serial Number: 7735H3FE10249
Current BIOS: Aptio v1.13 (Build Date: 02/21/2023)
EC FW Version: 1.15
CPU: AMD Ryzen 7 7735HS with Radeon Graphics
Memory: 64 GB DDR5-4800 (2× 32 GB Kingston KF556S40-32)
Storage: Kingston NVMe SNV2S 500GB (Kali Linux) / Samsung SSD 870 EVO 2TB (Windows 11)
Problem Description
My system has been suffering from random, silent reboots when running Linux (kernel 6.19) bare-metal. Upon reviewing the kernel logs after each reboot, I consistently find the following entry:
x86/amd: Previous system reset reason [0×08000800]:
an uncorrected error caused a data fabric sync flood event
This indicates that the Unified Memory Controller (UMC) detected an uncorrectable DRAM error and triggered a hardware-level reset before the operating system could intervene.
What I Have Already Attempted
I have spent considerable time troubleshooting this issue and have tried the following measures:
Applied extensive kernel-level mitigations, including disabling C-states, disabling amd-pstate, disabling PCIe ASPM, disabling runtime PM, forcing IOMMU passthrough, disabling NVMe APST, and ignoring GPIO wake-up interrupts. Unfortunately, none of these prevented the crashes.
Tested the system with the original 32 GB Crucial memory module that came with the unit. Reboots still occurred, which leads me to believe the issue may be rooted in the BIOS firmware rather than the memory modules themselves.
Monitored temperatures and voltages, which remained within normal ranges.
Confirmed the issue is not specific to the operating system, as the reset is triggered at the hardware level.
My Request
I understand from my research that Beelink has released BIOS versions v117 and newer, which include important fixes for DDR5 memory training compatibility on Rembrandt/Barcelo platforms. My current BIOS v1.13 (February 2023) predates these improvements.
I would be most grateful if you could kindly provide:
The latest BIOS file (.bin or .exe) suitable for my exact unit (SER6 PRO, SN 7735H3FE10249).
Clear flashing instructions for both Windows and USB/UEFI shell methods, if available.
A changelog or release notes confirming the DDR5 memory training fixes, should that be possible.
I have attached the relevant dmidecode output and journalctl logs showing the DFSF error pattern for your reference.
Thank you very much for your time and support. I truly appreciate any help you can offer in resolving this matter.
With warm regards,
Ruben
