Intel X99 Chipset Motherboard for LGA2011-3 Socket CPUs with Quad-Channel DDR4 Support

This ATX form factor motherboard is centred on the Intel X99 platform, providing a robust foundation for building a high-performance desktop computer or workstation. Its core specification is the LGA2011-3 CPU socket, offering compatibility with a range of powerful processors, including the Intel Core i7 series (such as the 5820K and 5960X) and the Xeon E5 V3 series (codenamed 'Haswell-EP'). This makes it suitable for users requiring substantial multi-threaded processing power for tasks like content creation, 3D rendering, or scientific computation. The board's design incorporates a quad-channel memory architecture and multiple high-speed expansion slots, balancing performance with practical connectivity for a modern system build.

Processor and Memory Compatibility

The motherboard's performance is defined by its supported CPUs and memory. The LGA2011-3 socket is versatile but comes with specific compatibility notes that are crucial for a successful build.

CPU Socket and Supported Processors

The LGA2011-3 socket accommodates Intel's high-end desktop (HEDT) and server processors from the relevant generation. You can use Intel Core i7 Extreme Edition processors from the Haswell-E family, such as the i7-5820K or i7-5960X. It also supports the Xeon E5-1600 v3 and E5-2600 v3 series processors, often used in workstations for their support of ECC memory and higher core counts. It is important to verify that your chosen CPU is from the correct V3 (Haswell) series, as this socket is not compatible with older V1/V2 or newer V4 processors.

Quad-Channel DDR4 Memory Configuration

The board features four DDR4 DIMM slots, enabling a quad-channel memory configuration for increased bandwidth. It supports DDR4 memory modules running at speeds of 2400 MHz or 2333 MHz. A key feature is its support for both standard unbuffered desktop DDR4 memory and Registered ECC (RDIMM) server memory. However, a critical restriction applies: if you install an Intel Core i7 consumer processor, you cannot use Registered ECC memory modules. The ECC functionality is only available when paired with a supported Xeon processor. The maximum supported capacity is 128GB, achieved by installing four 32GB modules.

Expansion and Storage Connectivity

This motherboard offers a comprehensive set of slots and ports for adding graphics cards, storage drives, and other expansion cards, catering to users who need substantial upgrade potential.

Graphics and General Expansion Slots

For graphics, the motherboard provides two PCI Express x16 slots, allowing for a dual-GPU setup (using NVIDIA SLI or AMD CrossFire, subject to driver and chipset support). Additionally, there are three PCI-E x1 slots for smaller expansion cards, such as dedicated sound cards, capture cards, or additional USB controllers. This layout provides flexibility for users who need to add multiple dedicated components beyond just a graphics card.

High-Speed Storage Options

Storage connectivity is a strong point. The board includes a dedicated M.2 slot that supports PCIe NVMe protocol SSDs, enabling significantly faster boot and load times compared to traditional SATA drives. For larger storage arrays, there are eight SATA3.0 (6 Gb/s) ports, allowing for numerous hard drives or SATA SSDs to be connected simultaneously. This combination of NVMe speed and high-capacity SATA support is ideal for users managing large media libraries, running virtual machines, or requiring fast scratch disks.

Integrated Features and System Management

Beyond core performance components, the motherboard integrates several features for audio, networking, and system diagnostics, aiming for a complete and user-friendly experience.

Integrated Audio, Networking, and Rear I/O

The onboard audio solution is a 7.1 channel HD audio codec, capable of delivering surround sound for gaming and entertainment without requiring a separate sound card. Networking is handled by an integrated Realtek RTL8111H Gigabit Ethernet controller, providing a reliable wired connection. The rear I/O panel is well-equipped, featuring a legacy PS/2 port for keyboard/mouse, an RJ45 LAN port, four USB 3.0 ports, four USB 2.0 ports, and the necessary 7.1 channel audio jacks. Two internal USB 2.0 and two USB 3.0 header sets offer further front-panel connectivity.

Power, Diagnostics, and Visual Elements

Power delivery uses a standard 24-pin ATX connector alongside an 8-pin EPS12V CPU power connector (it can operate with a 4-pin connector plugged into the 8-pin socket, but a full 8-pin is recommended for stability with high-power CPUs). For troubleshooting, the board includes a digital fault diagnosis display (often called a POST code display) and a system buzzer, which are invaluable tools for identifying hardware issues during boot. Aesthetic touches include an 8-LED colour audio trace that reacts to sound output and a designated interface for adding a WiFi module.
