What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.8 for now.

Third-party reviews

What customers like about ASRock X99 WS

  • Excellent workstation features including support for Intel Xeon E5-1600/2600 v3 and Core i7 processors.
  • Robust build quality with server-grade components like 12k platinum capacitors and 60A power chokes.
  • Extensive expandability with up to 128GB DDR4 RAM support and 5 PCIe 3.0 x16 slots for multi-GPU setups.
  • Stable networking provided by dual Intel Gigabit LAN with teaming support.
  • User-friendly and polished UEFI BIOS that includes helpful tools like a 'System Browser' for identifying connected hardware.
  • Good overclocking potential for both CPU and memory once the BIOS is updated to a stable version.

What customers don't like about ASRock X99 WS

  • High retail price compared to consumer-grade X99 motherboards.
  • Noisy southbridge/chipset fan which some users found irritating in quiet environments.
  • Initial BIOS versions were reported as unstable or 'flaky,' requiring immediate updates for full functionality.
  • Specific memory compatibility issues, particularly with achieving rated speeds for certain high-frequency DDR4 kits.
  • Inconvenient placement of supplemental PCIe molex power connectors, making cable management difficult.
  • Slow POST (Power-On Self-Test) times compared to some competing enthusiast-level boards.

Verdict

The ASRock X99 WS is a workstation-grade EATX motherboard designed for the LGA 2011-3 socket, supporting Intel Core i7 and Xeon E5-1600/2600 v3 processors with up to 18 cores and a 160W TDP. It features a robust 12-phase power design with 60A chokes and 12K platinum capacitors, alongside eight DDR4 DIMM slots supporting up to 128GB of quad-channel memory at overclocked speeds of 3200+ MHz (ECC/RDIMM supported with Xeon CPUs). Connectivity is a standout with six PCIe 3.0 x16 slots (supporting 4-way SLI/CrossFireX at x8/x8/x8/x8), dual Intel Gigabit LAN with teaming, ten SATA3 ports, and an Ultra M.2 slot (Gen3 x4). Main pros include its 'Ultra Thin' design for 1U server chassis compatibility, high-quality Super Alloy components for stability, and extensive multi-GPU support. However, potential cons include the lack of native USB 3.1 support and limited M.2 flexibility, as the M.2 slot shares bandwidth with specific PCIe slots, potentially disabling them during use.
