Socket LGA 1156 ATX motherboard

The ASUS P7P55D PRO is an ATX motherboard built around the Intel P55 chipset for LGA 1156 processors. It supports DDR3 memory up to a maximum of 16 GB. The board ships as a new component with one SATA cable and a chassis I/O back panel included.

Builders matching the LGA 1156 platform

This board suits builders replacing or assembling a system on the LGA 1156 platform with DDR3 memory. It is not for buyers who need a newer socket, a different chipset, or memory capacity beyond 16 GB. The product is supplied new without original packaging or additional accessories beyond the listed cable and panel.

16 GB DDR3 memory ceiling

The decisive specification is the 16 GB maximum memory supported across the DDR3 slots. If the intended build requires more than 16 GB of system memory, this motherboard cannot meet that requirement and another board must be selected.

Questions about this item

What case clearance and mounting points does the ATX form factor of the ASUS P7P55D PRO require?

The board follows the ATX layout, so it needs a case with ATX motherboard standoffs and the standard nine mounting holes; verify the rear I/O shield aligns with the supplied back-panel plate before securing the board.

What is the correct sequence for seating a processor in the LGA 1156 socket on this motherboard?

Open the socket lever, align the processor notches with the socket keys, place the CPU gently without forcing, close the lever until it locks, then attach the cooler; the step often missed is confirming the lever is fully latched before applying thermal paste.

Which components supplied with the ASUS P7P55D PRO will need replacement during the board's service life?

The package includes a metal battery and one SATA cable; the coin-cell battery maintains BIOS settings and will eventually need swapping, while the SATA cable should be replaced if connectors wear or signal errors appear.
