GIGABYTE GA-B250M-DS3H LGA1151 Motherboard: features, specs and who it suits

The GIGABYTE GA-B250M-DS3H is a Micro ATX motherboard for the LGA1151 socket, supporting 6th and 7th generation Intel Core processors. It is an older platform, so it is mostly of interest to people repairing, rebuilding or extending an existing system. Here is what the listed specs mean.

Processor support and the LGA1151 socket

GIGABYTE lists support for 7th and 6th generation Intel Core processors. LGA1151 is a socket name that was used across several generations, and the processor generation must match the board's chipset. A board in this family generally does not accept newer processors that use a different socket, so check the model number of the processor you plan to use against GIGABYTE's support list.

The listing also says the board is Intel Optane memory ready. Optane was a caching technology that sped up a conventional hard drive. Check that your setup still needs it before relying on it.

Memory

The board has four DIMM slots for DDR4 memory, in a dual-channel arrangement. Dual channel means that installing memory in matching pairs, in the correct slots, typically increases memory bandwidth. Check GIGABYTE's specification sheet for the maximum capacity and supported speeds, because the listing doesn't state them.

Storage

The listing names an M.2 connector with PCIe Gen3 x4, with up to 32 Gb/s of data transfer. That is the slim format for fast solid-state drives, and x4 refers to the four lanes it uses. The listing doesn't give the SATA port count, so check the manual if you plan many drives.

Audio, firmware and software

Audio comes from a Realtek ALC887 codec, a common choice on mainstream boards. The listing states UEFI Dual BIOS, meaning the board holds two copies of its firmware so it can recover if one is corrupted, a feature that GIGABYTE offers on many boards. GIGABYTE's APP Center includes the Easy Tune and Cloud Station utilities, which are used for system tuning and file or device sharing.

Size

The Micro ATX form factor measures 226 mm x 193 mm, as listed. This fits Micro ATX and ATX cases and many compact ones. Micro ATX boards have fewer expansion slots than full-size ones, which is enough for a graphics card and a small add-in card or two.

Who it suits

It suits owners of 6th or 7th generation Intel systems who need a replacement board, people building a basic retro or secondary PC, and anyone doing a repair where a matching socket and DDR4 memory are required.

What to check before you buy

• Processor: confirm that its generation and model are supported and what BIOS version is needed.
• Memory: check that you have DDR4 modules, not another type.
• Operating system: older platforms may have limited driver support in the newest operating systems, so check GIGABYTE's driver page.
• Case and ports: confirm Micro ATX support and the ports you need for displays, USB and networking.
• Condition and accessories: check what is included in the box, such as the rear I/O shield and cables.

The short version

• A Micro ATX LGA1151 motherboard for 6th and 7th generation Intel Core processors.
• Four DDR4 slots in dual channel.
• PCIe Gen3 x4 M.2 connector up to 32 Gb/s.
• Realtek ALC887 audio, UEFI Dual BIOS and GIGABYTE APP Center.
• Most relevant for repairs and rebuilds of existing LGA1151 systems.
