GIGABYTE GA-P61-S3 rev.2.0 LGA 1155 ATX Motherboard

This motherboard uses the Intel H61 chipset and fits the LGA 1155 socket. It provides two DDR3 DIMM slots for up to 16GB of system memory. The board follows the standard ATX layout measuring 30.5 by 19 centimetres.

Suits repairs and legacy builds; not for new systems

The board targets users replacing a failed H61 motherboard or assembling a system around an existing LGA 1155 processor. It lacks modern interfaces such as USB 3.0 or SATA 6Gb/s, so builders starting a new platform should select a current chipset.

PCI Express x16 slot with 3.0 support

A single PCI Express x16 slot operates at the 3.0 specification when the installed processor and graphics card both support it. This slot determines which graphics cards can run at their rated bandwidth.

Questions about this item

What PCI Express generation does the single x16 slot support, and what limits its speed in practice?

The x16 slot is wired for PCI Express 3.0, but actual Gen 3 operation depends on the installed CPU and graphics card; if either lacks Gen 3 support the link falls back to a lower generation.

What are the board dimensions and mounting pattern for case fitment?

The board measures 30.5 by 19 cm and follows the standard ATX mounting pattern, so it fits any case that accepts ATX motherboards.

How is the front-panel audio header connected to enable 7.1 channel output, and what step is often missed?

Connect the case front-panel audio cable to the onboard HD audio header; 7.1 channel output only activates when speakers are plugged into that front panel, not the rear jacks.
