Who it fits

Key specs explained for this module

Capacity: 16GB

This value indicates the total storage for active data on a single stick. You get 16 gigabytes per module. This size fits standard server configurations. It balances cost and performance. You can install multiple sticks to increase total system memory. This helps run more virtual machines or databases at once without slowing down.

Memory Speed: 4800MHz

This number shows how fast the memory transfers data. 4800MHz is the base rate for DDR5. It matches the PC5-38400 rating. Faster speeds reduce latency for server tasks. You benefit when handling large datasets. Compare this to older DDR4 speeds. Higher bandwidth supports modern server workloads better than slower alternatives.

ECC Support: ECC Registered

This feature corrects data errors automatically. It uses Registered DIMM technology to stabilize signals. This is critical for servers handling sensitive data. You avoid crashes from bit flips. It is not for desktops. You must ensure your motherboard supports this type. It adds reliability for continuous operation in enterprise environments.

Form Factor: 288-Pin RDIMM

This defines the physical shape and connector pins. 288 pins fit specific server slots. RDIMM means it has a register for signal buffering. You need compatible server hardware. It does not fit desktop or laptop computers. Check your system manual before buying. The pin count ensures proper electrical connection and compatibility.

Voltage: 1.1V

This is the operating power level. DDR5 uses 1.1V, which is lower than DDR4. Lower voltage reduces heat and power use. This helps keep servers cool. It improves energy efficiency for data centers. You save on electricity costs over time. It is a standard for modern DDR5 modules. Ensure your power supply handles this requirement.

Physical design and build details

The module measures 5.25 inches in length, 1.23 inches in width, and 0.15 inches in height. This standard RDIMM footprint ensures it fits into standard server slots. The listing describes the PCB color as green. You should expect a simple, functional appearance without decorative elements. The weight is listed at 0.35 ounces. This light mass helps reduce stress on server motherboard slots during installation. The 288-pin connector aligns with DDR5 server standards. You must ensure your server supports this specific pin layout. Mixing this with non-RDIMM modules is not possible. The physical design prioritizes compatibility over aesthetics. The single-rank x8 configuration is internal to the chip layout. You cannot see this from the outside. The 1.1V operating voltage is standard for DDR5. This helps manage heat in dense server racks. The listing notes that this memory is for select DDR5 servers and workstations. It is not compatible with desktop or laptop computers. You should check your system manual before purchase. The physical dimensions and pin count are critical for proper fit. The listing provides these details to help you verify compatibility. The build is straightforward. It focuses on delivering reliable memory for enterprise use. The lack of extra features keeps the design simple. This simplicity reduces potential points of failure. You get a module built for stability. The physical specs support this goal. The listing confirms these dimensions and weight. You can use this information to plan your server setup. The design matches the intended professional environment.

Setup and everyday use

You must verify your hardware before installing this module. The listing states it is not compatible with desktop or laptop computers. It is designed for select DDR5 servers and workstations. You need a system that supports Registered DIMMs. Do not mix this memory with other ECC types. You cannot combine it with ECC Unbuffered, ECC Load Reduced, or Non-ECC Unbuffered modules. Mixing types will prevent the system from booting. You should refer to your system manual for memory seating and channel guidelines. Proper installation ensures the 288-pin connector aligns correctly with the server slot. Once installed, the module operates at 1.1V. This voltage is standard for JEDEC DDR5 standards. The 4800MHz speed allows data to transfer quickly between the memory and the processor. ECC Registered support corrects data errors in real time. This feature is critical for server environments where data integrity is mandatory. Everyday use involves handling heavy workloads without bottlenecks. The 16GB capacity expands your system's available memory resource. You can install multiple sticks to increase total capacity. This improves performance and increases workload capacity. The module runs silently and requires no additional drivers. You simply rely on the server’s BIOS to recognize the hardware. Regular maintenance involves ensuring adequate cooling for the server chassis. The physical dimensions are standard, so airflow is not obstructed. You get a stable foundation for enterprise applications. The green PCB is visible only during maintenance. You do not need to adjust settings manually. The system manages the memory automatically based on the JEDEC standard.

Before you buy this server memory

You need a compatible DDR5 server or workstation to use this module. It does not fit desktops or laptops. Check your motherboard manual for supported RDIMM speeds. This stick runs at 4800MHz. Your system must support that frequency. Do not mix it with other ECC types. Unbuffered or load-reduced memory will cause errors. You may need additional sticks for proper channel configuration. This 16GB module expands your server’s resource pool. It helps reduce bottlenecks for heavy workloads. It sits alongside other server-grade RAM in our guide. Unlike desktop kits, this is strictly for enterprise use. You must verify your hardware compatibility first. Ensure your power supply handles the 1.1V requirement. Regular maintenance includes checking for thermal issues in server racks. This module improves capacity but requires specific system support. It is not a plug-and-play solution for personal computers. You need technical knowledge to install it correctly. Read the listing notes on memory seating guidelines carefully. This ensures stable operation and prevents boot failures.

Check before you buy

• Verify your system supports DDR5 RDIMM modules
• Confirm compatibility with 4800MHz speed settings
• Check motherboard manual for memory channel guidelines
• Ensure no other ECC types are installed
• Validate server workload capacity requirements
