LGA 1156 Micro ATX Motherboard

The ASUS P7H55D-M PRO is a new Micro ATX motherboard built on the Intel H55 chipset for the LGA 1156 socket. It accepts DDR3 memory up to 16 GB and includes one SATA cable and the rear I/O panel in the box.

System Maintenance and Light Builds

This board suits technicians replacing a failed H55 board in an existing LGA 1156 system or builders assembling a basic office PC that does not need more than 16 GB of RAM. Buyers who require a newer socket, higher memory capacity or additional expansion slots should look at a different platform.

16 GB DDR3 Memory Limit

The maximum supported memory is 16 GB of DDR3, which determines whether this motherboard can meet the workload. If the intended use needs more memory than this ceiling, the board will not be suitable.
