What Are the Most Common DeskMini B660 Firmware Bugs?
Common bugs include BIOS boot failures, USB 3.2 Gen2 port disconnections, and DDR4 RAM compatibility errors. Users also report intermittent Wi-Fi dropouts and incorrect fan speed readings. These issues stem from firmware conflicts with newer hardware components and power management settings. ASRock’s patches target these bugs through revised microcode and voltage regulation adjustments.
BIOS boot failures often manifest during system wake-from-sleep states or when using specific NVMe drives. The 1.40 update addresses this by refining power delivery sequences to SSDs during initialization. USB connectivity problems typically occur with high-bandwidth devices like external storage, where the firmware previously mismanaged data packet prioritization. Version 1.30 introduced dynamic bandwidth allocation to prevent port resets. RAM compatibility improvements focus on XMP profile stability, particularly for DDR4-3600+ kits, through enhanced memory training algorithms.
| Issue Type | Patch Version | Resolution Method |
|---|---|---|
| USB Disconnections | 1.30 | Controller timeout adjustments |
| RAM Compatibility | 1.40 | Updated SPD profiles |
| Fan Speed Errors | 1.40 | PWM calibration tables |
How to Safely Install DeskMini B660 Firmware Updates?
Download the firmware from ASRock’s official site, extract the file to a FAT32-formatted USB drive, and reboot into BIOS. Use Instant Flash under the “Tools” tab to apply the update. Avoid interrupting power during the process. Post-update, reset BIOS to default settings, then reconfigure preferences like XMP profiles or boot order.
Before initiating the update, ensure your USB drive uses MBR partitioning rather than GPT, as some BIOS versions struggle with GUID partitions. Validate the firmware file’s checksum using utilities like Hashtab to prevent corruption-related installation failures. If the update process stalls at 50%, wait at least 10 minutes before restarting—many boards perform secondary validation checks mid-flash. Successful installations typically display a “Firmware Update Complete” message followed by two automatic reboots.
| Step | Critical Notes |
|---|---|
| USB Preparation | Use 16GB or smaller drive |
| BIOS Access | Press F2/Del during POST |
| Post-Update | Re-enable TPM if used |
Why Are Post-Update BIOS Resets Critical for Stability?
Does the DeskMini B660 Support Firmware Rollbacks?
ASRock does not officially support rollbacks due to potential bricking risks. However, advanced users can force-downgrade via Uniflash tools. This voids warranties and requires manual checksum verification. Always backup current firmware before attempting rollbacks.
“Firmware bugs in compact systems like the DeskMini B660 often arise from hardware-software integration challenges. ASRock’s iterative patches reflect their commitment to resolving edge cases, but users must prioritize compatibility testing after updates.”
