Who it fits

Key specs explained for this kit

Capacity: 64GB

This module holds 64GB of data in a single stick. You get one large block of memory rather than multiple smaller ones. This is ideal for servers needing high density per slot. It helps virtualization and databases run smoothly without swapping to disk. Compare this to lower capacities if you have many slots available, as fewer sticks can sometimes improve airflow and stability in crowded server chassis.

Memory Speed: 2133MHz

The RAM operates at 2133MHz, which defines how fast data moves between the memory and the processor. This is a standard speed for DDR4 server memory. It ensures compatibility with older or conservative server platforms that do not support higher frequencies. If you are upgrading an existing system, matching this speed prevents bottlenecks. Higher speeds exist, but this value prioritizes stability and broad compatibility for enterprise workloads.

ECC Support: ECC

Error Correction Code (ECC) detects and fixes single-bit memory errors automatically. This prevents data corruption and system crashes during long-running tasks. You benefit from this if you run critical databases, financial applications, or 24/7 services where data integrity is non-negotiable. Standard non-ECC RAM lacks this safety net. Always verify your server motherboard supports ECC, as some consumer boards ignore or disable this feature entirely.

Form Factor: 288-pin LRDIMM

LRDIMM stands for Load-Reduced Dual In-line Memory Module. It uses a buffer to reduce the electrical load on the memory controller. This allows servers to install more sticks and reach higher total capacities than standard RDIMMs. You must check your server manual to confirm LRDIMM support, as it is not compatible with standard desktop or basic server slots. It is designed for high-DIMM-count enterprise boards.

Voltage: 1.2V

This module runs at 1.2 volts, which is the standard voltage for DDR4 memory. Lower voltage reduces power consumption and heat generation compared to older DDR3 standards. This helps keep your server room cooler and lowers energy bills over time. It also contributes to longer component lifespan. Ensure your server power supply and motherboard regulation support this standard voltage for optimal stability and efficiency during heavy loads.

Physical Design And Build

According to the listing, this module measures six inches in length with a height and width of 0.5 inches. The physical profile is standard for server DIMMs, allowing it to fit into dense rack configurations without interfering with adjacent slots or airflow. The unit weighs four ounces, a modest weight that reflects the internal components and the printed circuit board construction.

The layout features a 288-pin connector designed specifically for LRDIMM slots. This form factor is critical for high-capacity server boards, as it supports load-reduced buffering. This buffering lowers the electrical load on the memory bus, enabling systems to run at higher capacities while maintaining stability. The module operates at 1.2V, which aligns with standard DDR4 voltage requirements for efficiency.

Finish and material choices prioritize reliability over aesthetics. The design focuses on electrical integrity and thermal management within a server environment. You should verify that your platform supports LRDIMM technology before installation. The physical dimensions ensure compatibility with standard server chassis, but the specific pin configuration and buffering requirements mean it is not suitable for consumer desktops or laptops. Always check your motherboard manual to confirm support for this density and form factor.

Setup And Daily Use Guide

This module is a single 64GB stick designed for server environments. You install it into a motherboard slot that supports the 288-pin LRDIMM form factor. The listing notes that this is not a standard UDIMM or RDIMM. You must verify your server or workstation board supports LRDIMM before installation. Incorrect installation can prevent the system from posting. The memory runs at 2133MHz with a voltage of 1.2V. This speed and voltage profile matches the expectations of many server memory controllers. The kit uses a 4Rx4 rank configuration. This specific rank structure helps the system recognize the full 64GB capacity. It ensures the module posts correctly without reducing available memory. The Load-Reduced design lowers electrical load on the memory bus. This feature allows high-DIMM-count boards to reach maximum capacity per channel. Daily use involves supporting virtualization, in-memory databases, and multi-socket workloads. The ECC support helps maintain data integrity during continuous operation. You should check your platform’s manual or Qualified Vendor List for supported memory types. The listing provides lifetime replacement warranty and free US-based technical support. This assistance is available if you encounter configuration issues. The physical dimensions are six inches long with a half-inch height and width. This standard profile fits into dense rack configurations. Ensure your cooling solution accommodates the module’s height. The setup process relies entirely on platform compatibility. Proper verification of your system’s specifications is essential for successful operation.

Before You Buy This Server Kit

You need a compatible server or workstation motherboard that explicitly supports 288-pin LRDIMM modules. Standard desktop boards do not accept this form factor. Verify your platform’s memory population rules in the manual or QVL. LRDIMM support and maximum capacity vary by BIOS and CPU generation. Ensure your system can handle 64GB per slot. You may need additional identical sticks for balanced channels. Do not mix LRDIMM with RDIMM or UDIMM. This high-density kit suits virtualization and in-memory databases. It fits alongside other server memory options but requires strict matching. Check your voltage requirements, as this runs at 1.2V. Confirm your memory controller supports 2133MHz speeds. Proper configuration ensures stable operation. Incorrect installation may prevent booting. This module is for professional environments only. It is not suitable for consumer PCs. Review your hardware specifications carefully before ordering to avoid compatibility issues.

Check before you buy

• Verify motherboard supports 288-pin LRDIMM form factor.
• Check BIOS for LRDIMM capacity limits.
• Confirm 1.2V voltage compatibility.
• Ensure CPU supports 2133MHz memory speed.
