  • Ultra Durable 3 copper cooling reduces operating temperatures
  • USB 3.0 ports deliver up to 5 Gbps transfer rates
  • 3x USB Power enables device charging while the system is off
  • SLI and CrossFireX ready for multi-GPU configurations

LGA1155 motherboard for second-generation Intel Core

The GIGABYTE GA-P67X-UD3R-B3 fits CPUs in the LGA1155 package, covering second- and third-generation Core i3, i5 and i7 models plus Pentium and Celeron variants. It targets builders who want a P67 Express platform without integrated-graphics dependency, so a discrete graphics card is required for display output. The board will not suit buyers who need onboard video or a newer socket.

Sustained load behaviour with Ultra Durable 3

Ultra Durable 3 construction uses extra copper layers to spread heat from the voltage-regulation area, helping the board run cooler during long compile jobs or extended gaming sessions. The P67 Express chipset and 10/100/1000 LAN controller remain stable without throttling under continuous multi-core workloads. Audio stays clean through the Realtek ALC889 codec with Dolby Home Theater support for 7.1-channel output.

Installation notes and common pitfalls

Four 1.5 V DDR3 DIMM slots accept up to 32 GB in dual-channel mode; populate the correct pair first to enable dual-channel operation. The single full-length PCI Express x16 slot runs at x16 electrical, so multi-GPU setups using SLI or CrossFireX will fall back to reduced lane widths. USB 3.0 headers and 3x USB Power ports add charging convenience, but front-panel USB 3.0 cables can be tight in compact cases.

Questions about this item

How much heat does the Ultra Durable 3 copper cooling handle during all-day loads?

The Ultra Durable 3 design uses copper layers to spread heat away from the power phases, keeping the board cooler under sustained 2nd-generation Core i5 or i7 workloads.

What memory kit do I need to populate the four DDR3 slots?

You must supply 1.5 V DDR3 DIMMs; the board accepts speeds from 1066 up to 2133 MHz and supports XMP profiles for automatic setup.

Will my existing PCI Express x16 graphics card run at full speed in the single PEG slot?

Yes, the sole PCI Express x16 slot operates at x16 electrical, so any compatible card gets the full bandwidth the board provides.
