X99 Chipset Motherboard for LGA2011-3 Intel Processors with Dual PCI-E and M.2 Support

This X99-series motherboard is engineered for users building high-performance desktop systems, workstations, or specialised computing rigs. It centres on the LGA2011-3 socket, a platform known for supporting powerful Intel processors with high core counts and substantial memory bandwidth. The board’s design prioritises expansion capability and stable operation, offering a comprehensive set of connectivity options for graphics, storage, and peripherals. It serves as a practical foundation for tasks that demand significant RAM capacity, multiple storage drives, and the potential for multi-GPU configurations, all within a standard ATX layout.

Core Specifications and Compatibility

The motherboard’s key specifications define its capabilities and the components with which it can be paired. Its compatibility is focused on a specific generation of Intel hardware, providing a clear upgrade path for users with compatible parts.

Processor and Socket

At the heart of the board is the LGA2011-3 CPU socket. This socket is designed for Intel’s high-end desktop (HEDT) and workstation processors from the relevant generation. It officially supports the Intel Core i7 series and the Xeon E5 v3 series of processors. Examples provided include the Core i7-5820K and i7-5960X. It is important to note the specific compatibility instruction: while the board supports both CPU families, an Intel Core i7 processor cannot be used in conjunction with server-type Registered ECC memory modules.

Memory Configuration

Memory support is a significant feature, with four DDR4 DIMM slots arranged to utilise a quad-channel architecture. This configuration can substantially increase memory bandwidth compared to dual-channel setups. The slots support DDR4 memory modules with speeds up to 2400MHz or 2333MHz. A key point of flexibility is that they can accept both standard unbuffered desktop memory and Registered ECC modules typically used in servers and workstations, though with the noted restriction when using Core i7 CPUs. The total supported capacity is 128GB, calculated as 4 slots multiplied by 32GB modules.

Chipset and Core Logic

The motherboard is based on the Intel X99 chipset. This chipset provides the core logic for the LGA2011-3 platform, managing data flow between the CPU, RAM, PCI Express lanes, and storage interfaces. It enables the high number of SATA and USB ports, as well as the allocation of PCI Express lanes for the graphics and expansion slots.

Expansion and Storage Connectivity

This motherboard offers a range of slots and ports for adding components and connecting storage devices, catering to users who need extensive system expansion.

PCI Express Slots

For adding graphics cards and other expansion cards, the board provides two full-length PCI Express x16 slots. These are the primary slots for installing dedicated graphics processing units (GPUs), allowing for either a single powerful card or a dual-card setup (like NVIDIA SLI or AMD CrossFire, subject to driver and licence support). Additionally, there are three shorter PCI Express x1 slots, suitable for sound cards, network adapters, or other specialised add-in cards.

Storage Interfaces

Storage connectivity is well-covered for both conventional and high-speed drives. There are eight SATA 3.0 (6Gb/s) ports, allowing for the connection of multiple hard disk drives (HDDs) or SATA solid-state drives (SSDs). For the fastest storage performance, the board includes one M.2 slot that supports the PCI Express NVMe protocol. This interface allows for the installation of NVMe SSDs, which connect directly via PCIe lanes for significantly higher sequential read and write speeds compared to SATA-based drives.

On-Board Headers and Internal Ports

Beyond the visible slots, the board features internal headers for case connectivity. These include two USB 2.0 headers (providing one set of ports) and two USB 3.0 headers (providing one set of ports) for connecting front-panel case USB ports. The power delivery system requires both a 24-pin ATX main power connector and an 8-pin EPS12V CPU power connector, with a note that the board can operate (presumably with limitations) if only a 4-pin CPU power connector is available.

Integrated Features and Build Considerations

The motherboard incorporates several key features on-board, reducing the need for additional cards and aiding in system assembly and troubleshooting.

Integrated Audio and Networking

Audio capabilities are handled by an integrated 7.1 channel audio chipset, eliminating the need for a separate sound card for most users. The rear I/O panel includes the standard 3.5mm audio jacks for connecting speakers or headphones to utilise this surround sound output. For network connectivity, a Gigabit Ethernet controller is integrated using the Realtek RTL8111H chip, providing a reliable wired network connection via the single RJ45 port on the back panel.

Diagnostics and Aesthetics

To assist with building and troubleshooting, the motherboard includes practical diagnostic tools. A digital fault diagnosis display (often called a POST code display) shows numerical codes during startup, which can be referenced against a manual to identify specific hardware issues. A buzzer is also present for audible beep codes. The board also features an audio circuit with an 8-colour LED lighting effect. A note on appearance advises that the colour of the slot baseplate may vary between production batches, and the product may undergo continuous optimisation and upgrades, so minor detail adjustments might not be immediately reflected in product descriptions.

Warranty and Support

The product comes with a warranty policy. The source text states a warranty period of three years, with the first year being free-of-charge service and the following two years being cost maintenance. The service is provided either by the shop or the manufacturer under a "Three Guarantees" service framework, which is a common consumer protection policy in some regions.
