What we like about ASUS X99 A

  • Excellent value for an entry-level X99 platform motherboard
  • High-end overclocking capabilities for both CPU and memory
  • Patent-pending OC Socket provides enhanced voltage regulation and performance
  • Comprehensive and user-friendly UEFI BIOS interface
  • Solid build quality using high-end components
  • Attractive black and white aesthetic that fits many builds
  • Rich feature set including M.2 x4, SATA Express, and Crystal Sound 2 audio
  • Effective AI Suite 3 software for Windows-based system tuning

What we don't like about ASUS X99 A

  • Lack of built-in Wi-Fi and Bluetooth modules
  • Absence of an onboard dedicated CMOS reset button
  • Boot times can be longer than some competitors
  • Limited RAID support (only 6 out of 10 SATA ports are RAID-capable)
  • Some users reported initial stability issues requiring immediate BIOS updates
  • Certain physical switches for EPU/TPU could have been integrated into BIOS
  • Potential clearance issues with large GPUs in the primary PCIe slot

Verdict

The ASUS X99-A is an ATX motherboard featuring the LGA 2011-v3 socket and Intel X99 chipset, designed for Haswell-E and Broadwell-E processors with support for up to 64GB of quad-channel DDR4 memory at speeds reaching 3200MHz (OC). Key characteristics include the patent-pending OC Socket for enhanced overclocking stability, 5-Way Optimization for one-click system tuning, and robust storage options such as a 32Gb/s M.2 x4 slot and SATA Express. Main pros include its support for 3-way SLI/CrossFireX configurations, premium Crystal Sound 2 audio, and a highly responsive UEFI BIOS that appeals to enthusiasts on a budget. However, notable cons include the lack of integrated Wi-Fi or Bluetooth, limited bandwidth sharing that disables the fourth PCIe slot when an M.2 drive is used, and a simplified I/O compared to higher-end Deluxe models.
