Who it fits

Key specs explained

CPU Socket: LGA 2011-3

This socket fits fifth and sixth-generation Intel Core i7 processors, as well as Xeon E5 V3 and V4 series CPUs. It does not support the older LGA 2011 socket or registered ECC memory for i7 chips. You must match your CPU to this specific socket type. This limits you to older generation hardware, which is common for budget server builds or legacy system upgrades.

Memory Type: DDR4

The board uses DDR4 memory with support for up to 128GB of capacity. It works with both standard desktop RAM and ECC server memory, but you cannot mix them. Supported speeds are 2133 and 2400 MHz. This flexibility helps you choose between cost-effective desktop sticks or reliable server-grade modules for stability. Just ensure all sticks are the same type to avoid boot failures.

M.2 Slots: 2

You get two M.2 slots, supporting both NVMe and SATA M.2 drives. NVMe slots use PCIe 3.0 x4, offering speeds around 2000 to 3000 MB/s. This lets you install fast storage for operating systems or heavy workloads. Having two slots gives you room for separate drives for data and backups. This is useful for users needing high-speed storage without occupying multiple SATA ports.

PCIe Version: PCIe 3.0

The primary graphics slot runs at PCIe 3.0 x16, providing 128 Gbps of bandwidth. Other slots are PCIe 2.0 x1. This supports modern graphics cards and expansion cards like network or sound adapters. PCIe 3.0 is standard for this chipset era. It ensures your GPU and other peripherals can communicate efficiently, though newer PCIe 4.0 or 5.0 devices will operate at older speeds.

Form Factor: Micro ATX

This board measures 23.5 by 18.5 centimeters, fitting into Micro ATX cases. It is smaller than standard ATX boards, saving space in your build. This size is ideal for compact server racks or smaller desktop towers. It still offers four memory slots and multiple expansion options despite the reduced footprint. Choose a Micro ATX case to ensure proper fit and airflow for your components.

Physical Design and Layout Details

The listing describes the MACHINIST board as a Micro-ATX form factor. Its dimensions are 23.5 by 18.5 centimeters, or 9.25 by 7.28 inches. The color option specified is red. This compact size allows you to fit the motherboard into smaller cases while retaining enough room for essential components. You do not need a full-size chassis to accommodate this hardware, which simplifies your build planning.

The layout includes four DDR4 memory slots and two M.2 interfaces. One M.2 slot supports NVMe drives, while the other handles SATA drives. This dual interface lets you install two different storage types on the same board. You also get three PCIe expansion slots. One is a PCIe 3.0 x16 slot for graphics cards, and two are PCIe 2.0 x1 slots for network or sound cards. These slots provide the connectivity needed for server tasks or specialized hardware.

According to the listing, the package includes a CPU fan bracket, a SATA cable, and an I/O baffle. The motherboard itself does not include a battery or a manual. You must download the manual from the product page. The board lacks a front-panel USB header in the provided data, so you may need to rely on rear ports. The red finish is purely cosmetic, but the compact layout ensures you can manage cables effectively in tight spaces.

Setup and everyday use guide

Installing this motherboard requires careful attention to compatibility. You must use processors with the LGA 2011-3 socket, such as fifth or sixth-generation Intel Core i7 chips or Xeon E5 V3 and V4 series CPUs. The listing notes that this board is not compatible with the older LGA 2011 socket. You cannot mix server memory and desktop memory on the same board. The four DDR4 slots support up to 128GB of RAM at 2400 or 2133 MHz. You can use standard memory or ECC server memory, but not both types together. The package includes the motherboard, a CPU fan bracket, a SATA cable, and an I/O baffle. It does not include a CMOS battery or a manual. You can download the manual from the product page if needed. For daily use, the board provides two M.2 slots for NVMe and SATA drives. These slots support PCIe 3.0 x4 protocols with speeds up to 3000 MB/s. You also get one PCIe 3.0 x16 slot for graphics cards and two PCIe 2.0 x1 slots for network or sound cards. If you encounter boot issues, the listing suggests resetting the CMOS or cleaning the metal contacts on the CPU and memory with an eraser. Diagnostic codes like FF may indicate incompatible CPUs or foreign objects on the pins. Codes such as b7 or b9 typically mean the motherboard does not detect the memory. You should ensure all connections are secure before powering on the system.

Before You Buy This Server Board

Before you buy this MACHINIST Micro-ATX server board, verify your existing hardware. You must use LGA 2011-3 CPUs, such as Xeon E5 V3 or V4 series, or sixth-generation Core i7 chips. Do not mix server and desktop memory; the board supports DDR4 up to 128GB, but these types cannot be used together. You need a compatible power supply and a CPU cooler, as the package includes only a fan bracket. The listing notes that manuals are not included, so you must download them. If you encounter boot issues, you may need to reset the CMOS or clean contacts. This board suits users building cost-effective workstations for rendering or virtualization. It fits alongside other X99 options for those prioritizing multi-core performance over modern features. Ensure your case supports the Micro-ATX form factor. Check that your storage needs align with the dual M.2 slots, which support both NVMe and SATA protocols. This setup requires technical comfort for installation and troubleshooting.

Check before you buy

• Verify your CPU is LGA 2011-3 compatible, like Xeon E5 V3/V4.
• Ensure you buy only DDR4 server or desktop memory, not both mixed.
• Confirm your case fits the 9.25 by 7.28 inch Micro-ATX size.
• Download the manual from the product page as it is not included.
