GIGABYTE GA-B75M-HD3 LGA 1155 Intel B75 Micro ATX Motherboard

SKU CH-MBDG-ZEBD7

Micro ATX B75 board with LGA 1155 socket supporting up to 32 GB DDR3 at 1600 MHz

  • CPU TypeIntel Core 13th Gen (LGA 1700)
  • Supports LGA 1155 Ivy Bridge CPUs
  • Intel B75 chipset for stable operation
  • Dual-channel DDR3 up to 1600 MHz and 32 GB
  • Realtek ALC887 8-channel audio with RTL8111F Gigabit LAN
  • PCI-E 3.0 slots and SATA 6 Gb/s connectivity

GA-B75M-HD3 LGA 1155 Board

This Micro ATX motherboard uses the Intel B75 chipset and fits LGA 1155 processors such as Core i7, i5, i3, Pentium and Celeron models. It is aimed at builders refreshing an older platform or assembling a basic office system that does not need modern CPU features.

DDR3 Dual-Channel Limits

The board provides two DDR3 DIMM slots supporting 1066, 1333 and 1600 MHz speeds up to 32 GB total. With only two slots, maximum capacity is reached by populating both; a single module runs in single-channel mode and limits throughput.

Replaces Earlier LGA 1155 Boards

It upgrades from first-generation Sandy Bridge boards by adding native PCI-E 3.0 support for Ivy Bridge CPUs and a Realtek RTL8111F Gigabit NIC. The jump is worthwhile when moving to an Ivy Bridge processor or when the original board lacks USB 3.0 and SATA 6 Gb/s ports.

Highlights

Questions about this item

Which memory capacity should I pick for this board?

The board supports up to 32GB of DDR3 across two DIMM slots, so choose a kit that does not exceed that total.

What does the 1600MHz memory rating mean once the board is running?

It indicates the highest DDR3 speed the chipset can run in dual-channel mode; actual speed will match the slowest module installed.

What PCIe standard does the expansion slot use and what does that limit?

The slot follows the PCI-E 3.0 standard, capping lane bandwidth to the 3.0 specification for any card you install.
