What customers like about GIGABYTE GA-Z77X-D3H Rev 1.2

  • Exceptional value-for-money at its price point
  • Excellent overclocking capabilities, reaching near 4.9 GHz on air cooling
  • Abundant connectivity with six USB 3.0 ports on the rear I/O
  • User-friendly 3D BIOS (Dual UEFI) that is intuitive for novice users
  • High build quality featuring 'Ultra Durable' components like Japanese capacitors
  • Includes a dedicated mSATA slot for SSD caching
  • Supports both 2-way SLI and CrossFire multi-GPU configurations

What customers don't like about GIGABYTE GA-Z77X-D3H Rev 1.2

  • Lacks premium 'sport' features like onboard power/reset buttons and diagnostic LEDs
  • Using the mSATA slot disables one of the standard SATA 2.0 ports
  • Limited to a single true PCIe x16 slot; bandwidth drops to x8/x8 in multi-GPU mode
  • Setting up an SSD cache via RAID mode may require a full Windows reinstallation
  • Reported issues with laggy mouse input and rough transitions in the BIOS interface
  • Only includes two native Intel SATA 6Gb/s ports; others are via third-party controllers

Verdict

The Gigabyte GA-Z77X-D3H (rev. 1.2) is an ATX motherboard featuring the Intel Z77 chipset and LGA1155 socket, providing native support for 2nd and 3rd Generation Intel Core processors. Key specifications include four DDR3 DIMM slots supporting up to 32GB of memory at overclocked speeds of 2800 MHz, dual-channel architecture, and triple PCI Express x16 slots (supporting PCIe 3.0). Main characteristics include an onboard mSATA slot for SSD caching, 2-way SLI and CrossFire multi-GPU support, and a high-quality 108dB SNR audio codec. Pros include its GIGABYTE 3D Power digital engine for precise voltage control, the 3D BIOS (Dual UEFI) for user-friendly navigation, and extensive connectivity with six rear USB 3.0 ports and HDMI/DVI/VGA outputs. However, cons include a limited 4-pin CPU power header that restricts extreme overclocking potential compared to high-end boards, and the fact that using the mSATA slot typically disables one of the standard SATA ports.
