Lenovo - ThinkSystem - DDR5 - module - 32 GB - DIMM 288-pins - 4800 MHz / PC5-38400

The Lenovo 4X77A81438 Memory Module is a 32 GB DDR5 server RAM module with a 4800 MHz clock speed. Built in a 288-pin DIMM form factor and supporting ECC, this module is intended for use in ThinkSystem and other compatible servers where data integrity and higher memory capacity are required for demanding workloads.

Advantages

This 32 GB DDR5 module provides higher memory bandwidth and improved performance compared with previous-generation memory, while ECC support helps detect and correct single-bit errors to increase system reliability. The 288-pin DIMM design ensures compatibility with standard server memory slots and allows modular capacity upgrades to match workload requirements.

Suitable for

• Big Data analytics and in-memory processing
• Virtualization and cloud computing hosts
• Database servers and transaction processing
• High performance computing (HPC) workloads
• Enterprise server memory expansion and upgrades

Key specifications

• Capacity: 32 GB
• Type: DDR5
• Clock speed: 4800 MHz
• Form factor: 288-pin DIMM
• Error correction: ECC support

How to use

Install the module into an empty compatible 288-pin DIMM slot on a powered-off server following the server manufacturer’s installation procedure. Ensure BIOS/firmware supports DDR5 memory and ECC operation. After installation, verify the system recognizes the new memory capacity in firmware/BIOS and operating system tools before placing the server back into production.

Recommendations

Use this memory module in matched pairs or according to the server vendor’s memory population rules to maximize performance and maintain supported memory channel configurations; consult the server compatibility list and update firmware as needed.
