ASUS Pro WS C422-ACE Intel C422 LGA 2066 Socket R4 ATX Workstation Motherboard

Description

Pro WORKSTATION MOTHERBOARD

ASUS Pro Workstation motherboards are designed for professionals in AI training, deep learning, animation, 3D rendering or media production. Featuring expandable graphics, extensive storage, impressive connectivity and exceptional overall performance and reliability, Pro Workstation motherboards are the ideal solution for creative professionals. Each motherboard includes centralized management software, so they’re also an efficient and cost-effective option for IT administrators.

Multi-GPU support

Fully loaded takes on new meaning when you have up to 48 PCI Express lanes and those lanes can be split in a 3-way x16/x16/x8 configuration spanning the board’s trio of PCIe x16 slots, allowing you to load up on GPUs to accelerate an increasingly diverse array of workloads, including AI training, 3D rendering, and scientific or financial modeling.

ASUS 2-WAY VGA holder User-friendly design

The Pro WS C422-ACE is packed with an exclusive two-way VGA holder to provide extra rigid support for up to two high-end graphics cards, to prevent potentially damaging bowing or bending. This VGA holder is easy to install and can be mounted with an additional system fan (up to 120mm), making sure your workstation has ample cooling to complete any task.

ProCool II power connector

The latest ProCool II is an enhanced EATX 8-pin power connector that offers higher endurance and longer lifespan by lowering impedance to prevent hotspots and connector failure. The new design includes upgrades to metal amour and solid pins for better dissipation, as well as a warning LED display with a BIOS POST message to indicate an improper connection.

Power stages with IR3555 design

The CPU VRM on Pro WS C422-ACE employs a 12+2 power stage design with IR3555, combining high-side and low-side MOSFETs and drivers into a single package, delivering the power and efficiency that high core count processors demand.

Alloy chokes

The Pro WS C422-ACE series uses efficient alloy chokes and high-quality thermal pads to help transfer heat from the VRM array to a sink with ample surface area for the processors.

Durable capacitors

Durable capacitors are engineered to resist extreme temperatures and provide up to 110% better performance than the industry standard.

8-layer PCB design

Multiple PCB layers shift heat away from critical components, providing more headroom to push your CPUs beyond stock speeds.

Triple M.2

With x4 PCI Express 3.0 bandwidth, Pro WS C422-ACE comes with three onboard M.2 slots — including one vertical slot — that support up to 32Gbps data-transfer speeds. The slots feature ultra-efficient, dual heatsinks that reduce M.2 SSD temperatures by up to 18.7°C for optimal storage performance and improved SSD longevity.

Dual U.2

Unleash NVMe storage devices with dual U.2 ports to experience data-transfer speeds of up to 32Gbps and free up a PCIe slot for another expansion card.

Upgrade your RAID

Intel Virtual RAID on CPU (VROC) obliterates PCH-based RAID arrays that are bottlenecked by the 32Gbps limit of the DMI bus, allowing you to utilize CPU PCIe lanes to configure a bootable RAID array that can transfer data at insane speeds. Pro WS C422-ACE supports RAID 0, 1, 5, 10 to provide fault tolerance and improve overall performance.

Trusted Stability

Pro WS C422-ACE provides enhanced features to smooth your IT operations, including comprehensive system protection, 24/7 stability and reliability.

Ultra-efficient MOS & PCH heatsink

Pro WS C422-ACE ensures optimal cooling and system stability for the Intel Xeon W Processors. Higher power requirements are balanced by carefully designed heatsinks that carefully balance mass and surface area to maximize thermal dissipation. In addition to the VRM-heatsink array and the heatpipe that’s positioned to provide maximum airflow within the chassis, a dedicated heatsink also help to efficiently dissipate heat from the PCH.

24/7 Dependability Quality reliability test

Optimized for twenty-four seven operations, the motherboard is tested under temperature up to 45°C and humidity up to 80% to ensure it can handle diverse temperature and humidity range of different location.

SafeSlot Protect your graphics card investment

SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using an insert-molding process, SafeSlot integrates the slot with fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.

Cooler by design Flexible cooling controls

Pro WS C422-ACE features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.

ASUS Control Center Express A server-grade IT management software

ASUS Control Center Express is centralized server-grade IT management software that takes just only a few minutes to install and is designed to reduce IT operations costs and improve efficiency. This powerful tool enables IT administrators to manage and control multiple clients in different locations remotely and includes features such as asset management, software deployment and monitoring. ASUS Control Center Express also lets IT staff visualize deployments, facilitating real-time control.

USB 3.2 Gen 2 back-panel connectors Future-proof connectivity

The back panel of the Pro WS C422-ACE features four USB 3.2 Gen 2 connectors, including one reversible Type-C and three backward-compatible Type-A to deliver ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps.

5-Way Optimization One-click overclock and cooling

ASUS 5-Way Optimization makes your PC smart. One click takes care of complex tuning, dynamically optimizing essential aspects of your system to provide overclocking and cooling profiles that are tailored for your rig.

An automated tuning utility that optimizes overclocking and cooling profiles for your unique system configuration.

Fans stay whisper-quiet with everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks.

Stress test function helps optimize and overclock for CPU- or memory-centric workloads.

CPU performance boost

The TurboV Processing Unit (TPU) is the intelligence behind our automated system-tuning utility, offering the ability to fine-tune voltages, monitor system stats, and adjust overclock parameters for optimal performance.

All-round energy efficiency

With the Energy Processing Unit (EPU) you’ll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.

Flexible cooling controls for air or liquid

With Pro WS C422-ACE you have comprehensive control over fans via Fan Expert 4 or our media-acclaimed UEFI. Whether you’re cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode, which reduces all fan speeds to below the default minimum — keeping your system whisper-quiet when performing light tasks.

Precise digital power control

Digi+ delivers real-time control over voltage droop, switching frequency and power -efficiency settings, allowing you to fine-tune CPU voltage regulation for ultimate stability and performance.
