Compatibility and revision notes
R2.0 is a specific hardware release. Do not flash BIOS for another M5A99X or R1.0 variant. Check the CPU support table for required BIOS and power envelope.
Before installation, check the manufacturer’s model-specific CPU support table and manual. Verify the power supply, cooler, chassis clearance, memory population rules and any shared PCIe or SATA lanes for the intended configuration.
Preservation and repair
Inspect AM3+ socket pins, VRM heatsinks and eSATA/SATA headers. Keep revision-matched firmware and note RAID mode and shared PCIe resources before servicing.
For an archive record, photograph PCB labels before cleaning and note serial/date codes, firmware, accessories, known faults, repairs and test conditions. Use ESD-safe handling; do not energize a board with loose conductive hardware beneath it.
