Who it fits

Key specs explained for this module

64GB Capacity

This single stick holds 64 gigabytes of data. You get a large memory pool for one slot. This helps servers run many apps at once without slowing down. It reduces bottlenecks when handling heavy workloads. You need fewer sticks to reach high totals. This saves space in your server chassis compared to using smaller modules.

5600MHz Memory Speed

The chip runs at 5600 megahertz. This is the PC5-44800 standard. Faster speeds move data quicker between the processor and memory. This improves response times for database queries and virtual machines. You benefit from smoother performance under load. Check your server manual to ensure it supports this rate.

ECC Registered RDIMM

This type corrects data errors automatically. The registered buffer stabilizes signals for large capacities. You get reliable operation for critical server tasks. It prevents crashes from corrupted memory bits. This is not for desktops. You must use a server motherboard that supports registered DIMMs for this to work correctly.

1.1V Voltage

The module uses 1.1 volts. This is the DDR5 standard. Lower voltage saves power and reduces heat. Your server runs cooler and uses less electricity. This is different from older DDR4 sticks. You need a compatible power supply and motherboard to handle this specific voltage requirement safely.

288-Pin Form Factor

The stick has 288 contact pins. This fits standard DIMM slots in servers. You need a slot that matches this physical shape. It will not fit in laptop or desktop computers. The notch position prevents wrong installation. Always verify your server slot type before buying this specific physical configuration.

Physical Design and Build Specs

The module measures 5.25 inches in length, 1.23 inches in width, and 0.15 inches in height. These dimensions conform to the standard 288-pin DIMM form factor. You need to ensure your server chassis has adequate clearance for this physical footprint. The single-rank design occupies one slot while providing substantial storage. This layout allows you to stack multiple modules in compatible server racks.

According to the listing, the module features a registered RDIMM architecture. This design includes a buffer chip on the PCB. The buffer stabilizes the memory signals for the CPU. You benefit from improved signal integrity when running many modules simultaneously. This makes the stick suitable for high-density server environments rather than compact desktop cases.

The physical construction uses JEDEC DDR5 standards. It operates at 1.1V, which is the standard voltage for this generation. The 2Rx4 configuration defines how the memory chips are arranged on the board. You must verify that your server supports this specific rank configuration. Mixing different rank types or ECC types can cause system instability. The build prioritizes server reliability and signal stability over aesthetic appeal.

Setup and everyday use

You must verify your hardware before installation. This module is an ECC Registered RDIMM designed exclusively for select server systems. It is not compatible with desktop computers, laptop computers, or standard PCs. Attempting to install it in consumer hardware will result in a failure to boot. You need to check your server manual to confirm support for DDR5 5600MHz PC5-44800 memory. The physical form factor is a 288-pin DIMM. You should ensure your server chassis has adequate clearance for the 5.25-inch length. During setup, you must follow memory channel guidelines for your specific motherboard. This module cannot be mixed with EC4 (9x4) ECC Registered modules or different ECC types like ECC Unbuffered or Non-ECC Unbuffered. Mixing incompatible memory types can prevent the system from initializing. Once installed, the 1.1V voltage rating ensures standard power consumption for server environments. The 64GB capacity provides a large memory pool for one slot. This helps servers run many applications simultaneously without slowing down. The 5600MHz speed rating supports high-bandwidth workloads. You will see improved performance when handling heavy data tasks. The system expands its available memory resource, reducing bottlenecks. This increases the overall workload capacity of your server infrastructure. You rely on the stability of the ECC Registered architecture for continuous operation. This setup is intended for enterprise-grade environments where data integrity and capacity are critical. You should verify compatibility with your specific server model before purchase.

Before You Buy This Server RAM

Before you buy this Samsung 64GB DDR5 5600MHz ECC RDIMM, confirm your server supports PC5-44800 speeds. This single-module kit requires a compatible motherboard and CPU that handle 1.1V DDR5 operation. You must verify the system accepts 2Rx4 (EC8, 10x4) registered memory. Do not mix these with EC4 or non-ECC modules, as incompatibility will prevent booting. Ensure your server chassis fits the 5.25-inch DIMM length. This high-capacity stick suits workloads needing large memory pools, like virtualization or databases. It sits alongside other server RAM options by offering substantial single-slot density. You should check your existing memory configuration to balance channels. Proper installation ensures stability under heavy loads. This module expands available resources, reducing bottlenecks. It is strictly for select server systems, not desktops or laptops. Verify compatibility with your specific server model and installed components to guarantee performance and stability.

Check before you buy

• Verify your server supports PC5-44800 DDR5 speeds.
• Confirm motherboard accepts 2Rx4 EC8 registered modules.
• Check chassis clearance for 5.25-inch DIMM length.
• Ensure CPU supports 1.1V DDR5 voltage.
• Do not mix with EC4 or non-ECC memory.
