Samsung M321R4GA0PB0-CWM

Overview

The Samsung M321R4GA0PB0-CWM is a 32 GB DDR5 ECC registered memory module designed specifically for modern servers that require fast and reliable system memory. Operating at 5600 MHz under the PC5-44800 standard, it supports high-performance multi-core processors by maintaining rapid and consistent data flow. This memory module is ideal for demanding environments such as virtualization, large database management, and high-traffic web or application servers.

Built to the JEDEC DDR5 standard and running at a low 1.1 V, it balances high speed with energy efficiency. The onboard register stabilizes clock, command, and control signals, while the integrated 8-bit error-correcting code continuously monitors and corrects data errors, ensuring system stability during intensive workloads.

Key features

• 32 GB capacity that expands server memory without replacing existing hardware
• High-speed 5600 MHz operation for smooth handling of parallel processing tasks
• ECC technology that detects and corrects data errors to maintain system integrity
• Registered DIMM architecture that stabilizes signal integrity for reliable performance
• Single-rank 1Rx4 layout suitable for servers supporting up to two DIMMs per channel
• Low 1.1 V power consumption to reduce energy costs and heat generation
• Designed exclusively for servers compatible with DDR5 RDIMM memory modules

compatibility and usage considerations

This memory module is intended solely for use in servers that support DDR5 RDIMM memory and operate at 5600 MHz speeds. It is not compatible with desktop PCs, laptops, or workstations that require unbuffered DIMMs (UDIMMs). Before installation, verify that your server’s motherboard or firmware supports this module to ensure proper operation. Its registered and ECC features make it a strong choice for enterprise environments where data integrity and uptime are critical.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
