ASUS P7H55-M LX LGA 1156 motherboard
This micro-ATX board uses the Intel H55 chipset and accepts Core i7, i5, i3 and Pentium processors in an LGA 1156 socket. It provides two 240-pin DDR3 slots running at 1333 or 1066 MHz with dual-channel support up to 8 GB. A single PCI Express 2.0 x16 slot, one PCI Express x4 slot and two legacy PCI slots handle expansion.
Who this suits and who should look elsewhere
Builders upgrading an existing LGA 1156 system or assembling a basic office PC will find the feature set adequate. The lack of onboard graphics means a discrete video card is mandatory, so systems relying on integrated output cannot use this board. Enthusiasts needing more than two memory slots or newer CPU generations must choose a different platform.
Checks before ordering
Verify that your processor is an LGA 1156 Core i7, i5, i3 or Pentium model and that your cooler fits the socket mounting holes. Confirm the power supply provides the required 24-pin ATX and 4-pin CPU connectors for this board. Ensure your case accepts micro-ATX dimensions and that a graphics card is available for the D-Sub and DVI video outputs.

Questions sur cet article
Do I need a separate graphics card because the ASUS P7H55-M LX has no onboard video chipset?
Yes, the board has no onboard video chipset, so a discrete graphics card is required for any display output. The back panel provides D-Sub and DVI ports that connect to the installed card.
Can I keep my existing PCI sound card and use it with the PCI Express x4 slot on this motherboard?
No, the PCI Express x4 slot accepts only PCIe devices. The board does include two legacy PCI slots, so a PCI sound card can be installed in one of those instead.
How can I confirm the board is running memory in dual-channel mode after installing two DDR3 1333 modules?
Enter the BIOS and verify the memory configuration shows dual-channel operation, or use a system-information utility in the OS that reports the active channel mode.
