GIGABYTE GA-P67A-UD3R-B3 Intel motherboard

LGA 1155 board for second-gen Intel Core builds

This GIGABYTE motherboard fits the LGA 1155 socket and accepts second-generation Intel Core i3, i5 and i7 processors plus Pentium and Celeron models in the same package. It uses the Intel P67 Express chipset and provides four DDR3 DIMM slots for up to 32 GB of system memory. The board targets builders assembling or repairing Sandy Bridge-era systems.

Memory and expansion limits set by the P67 platform

The four slots support dual-channel DDR3 at speeds from 1066 MHz to 2133 MHz including XMP modules, but 32-bit Windows will not show more than 4 GB. A single PCI Express x16 slot runs at x16 for one graphics card; CrossFireX is supported for multi-GPU setups. Onboard audio uses the Realtek ALC889 codec with 7.1-channel output and Dolby Home Theater, while LAN is handled by a Realtek RTL8111E controller at 10/100/1000 Mbit.

Straightforward ATX install

The board follows standard ATX mounting and uses a 24-pin plus 8-pin power arrangement familiar to experienced builders. USB 3.0 headers and 3x USB Power ports with On/Off Charge add front-panel convenience. Typical issues include forgetting the CPU power connector, exceeding the 1.5 V DDR3 voltage limit, and needing a discrete graphics card for processors without integrated graphics.
