How to use
Power down the server or workstation and follow the manufacturer’s ESD procedures before installing memory. Locate the appropriate DIMM slots on the motherboard, open the retention clips, and firmly insert the 288-pin DIMM until the clips engage. Populate memory according to the server’s channel and population guidelines for optimal performance. After installation, power on the system and verify that the BIOS/UEFI recognizes the new 16 GB module and that ECC is enabled if required.
Usage recommendations
For best results, install HPE SmartMemory modules in matched pairs or according to the server vendor’s memory population rules. Use modules that match in speed and timings to avoid falling back to lower supported speeds. Ensure firmware/BIOS is up to date for full compatibility with 2933 MT/s operation on supported HPE Gen10 AMD and other certified platforms.
