LGA 1155 Z77 ATX board

This GIGABYTE GA-Z77-DS3H rev.1.0 is an ATX motherboard built around the Intel Z77 chipset for LGA 1155 processors. It accepts Core i7, i5, i3, Pentium and Celeron CPUs and provides four DDR3 DIMM slots for up to 32 GB of memory.

Builders keeping an LGA 1155 system alive

The board suits anyone extending the life of an existing Sandy Bridge or Ivy Bridge platform, especially if they need SATA III ports and a PCI Express 3.0 x16 slot. It will not suit builders starting a new platform or anyone who needs more than four memory slots.

Four DDR3 slots, 32 GB ceiling

The decisive specification is the four DDR3 DIMM sockets with a 32 GB maximum. If the intended CPU and workload require more memory than that, this motherboard cannot meet the requirement.

Questions about this item

Which processor do I need to install in the LGA 1155 socket for this Z77 board to function?

The socket accepts Intel Core i7, i5, i3, Pentium or Celeron CPUs built for LGA 1155; choose one of those to power the system.

Will my existing PCI Express 2.0 graphics card run in the PCIEX16 slot that supports PCI Express 3.0?

Yes, the slot is backward compatible, so a PCIe 2.0 card will operate at PCIe 2.0 speeds without any extra configuration.

How can I verify the Realtek ALC887 audio chip is delivering 7.1-channel output after I connect the front-panel header?

Open the Realtek control panel in Windows, select 7.1 speaker configuration and run the speaker test; all eight channels should play a tone.
