Product overview

The Lenovo SM37B73342 is a 64GB DDR5 SDRAM memory module designed specifically for server environments. With a memory size of 64GB in a single module, it provides substantial capacity for handling large datasets and memory-intensive applications. Operating at 6400MHz (PC5-51200), this module delivers high-speed performance essential for modern data centers and enterprise computing. As a registered DIMM (RDIMM) with ECC (Error-Correcting Code), it ensures data integrity by detecting and correcting errors, minimizing downtime in mission-critical operations. The 288-pin form factor is compatible with Lenovo ThinkSystem servers and other platforms supporting DDR5-6400 standards. Key features include dual-rank x4 organization, which optimizes signal integrity and supports higher memory densities, and low voltage operation typically at 1.1V-1.2V for improved power efficiency. This module is ideal for virtualization, big data analytics, AI training, and high-performance computing (HPC) workloads where reliability and speed are paramount. In bulk deployments, it enables scalable memory configurations up to terabytes per server, reducing the need for frequent upgrades. Procurement teams benefit from its OEM-qualified design, ensuring seamless integration without compatibility issues. Compared to DDR4 predecessors, DDR5 offers up to double the bandwidth and improved channel efficiency, future-proofing IT infrastructure investments. Installation is straightforward in standard server chassis, with a compact form factor (approximately 5.2 x 1.2 x 0.2 inches) and lightweight shipping weight of 0.20 lb. For organizations prioritizing uptime and performance, the SM37B73342 represents a robust, high-capacity memory solution backed by Lenovo's enterprise-grade manufacturing standards.

Does it support ECC and what are the benefits?

Yes, it features full ECC error-correcting code, which detects and fixes single-bit errors in real-time. This ensures data integrity in mission-critical servers, reducing downtime and maintaining reliability for 24/7 operations.

What is the form factor and pin count?

It is a 288-pin RDIMM (Registered DIMM), standard for modern server motherboards. This form factor supports high-capacity configurations and is compatible with Lenovo ThinkSystem platforms supporting DDR5-6400.

What speed and latency does it offer?

Rated at 6400MHz (PC5-51200) with typical CL52 CAS latency. Dual-rank x4 design optimizes performance in multi-channel setups, delivering superior bandwidth over DDR4 for HPC and analytics workloads.

Is it suitable for bulk server deployments?

Yes, as a registered ECC module, it scales well in arrays up to multiple TB per server. Low voltage (1.1V-1.2V) aids power efficiency, making it ideal for data centers procuring in volume for consistent performance.

What servers is it compatible with?

Primarily Lenovo servers supporting DDR5-6400 PC5-51200 RDIMMs, such as ThinkSystem SR650 V3 or equivalents. Verify motherboard specs for slot count and channel population to maximize throughput.
