Samsung M386ABG40M51-CAE

Overview

The Samsung M386ABG40M51-CAE is a 256GB DDR4 LRDIMM memory module designed to meet the demands of enterprise servers handling memory-intensive tasks. Operating at 3200 MHz under the PC4-25600 standard, it ensures fast data delivery to modern multicore processors, supporting environments such as large virtual machines, in-memory databases, and real-time analytics without bottlenecks.

This module uses a Load Reduced DIMM design that places a register and data buffer between the memory controller and DRAM chips, reducing signal noise and allowing more modules per channel while maintaining system stability. Built-in error-correcting code (ECC) protects against data corruption, which is critical for maintaining uptime and avoiding costly errors in server operations.

Key features

• Load Reduced DIMM architecture that reduces electrical load and signal noise for higher memory density and stability
• Error-correcting code (ECC) to detect and correct data errors, enhancing reliability in critical server applications
• High-speed 3200 MHz operation to keep pace with demanding multicore processors and data-intensive workloads
• Low voltage operation at 1.2 V to reduce power consumption and heat generation in dense server environments
• Eight-rank by four-bank organization optimized for compatibility with dual-socket and multi-socket server platforms

Key specs

• Capacity: 256 GB
• Memory type: DDR4 LRDIMM
• Speed: 3200 MHz (PC4-25600)
• Voltage: 1.2 V
• Architecture: 8Rx4
• Pin count: 288-pin

Connectivity and compatibility

This memory module is designed for server motherboards that support DDR4 Load Reduced DIMMs, commonly found in dual-socket and multi-socket configurations. Its 288-pin interface and JEDEC compliance ensure broad compatibility with enterprise-grade platforms that require high memory capacity and error correction.

It fits well in virtualization hosts running multiple guest machines, high-performance computing clusters, and enterprise resource planning servers where consistent memory performance and data integrity are essential.

Orders are processed within 2 business days, which includes verification, packing, and dispatch. Shipping costs are calculated at checkout based on destination, total weight, and selected speed. Free shipping applies to carts over $100 (excluding heavyweight items). All available options and final pricing are clearly shown before payment so you can choose the service that best fits your needs.

Deliveries are handled by major carriers such as USPS, UPS, and FedEx. Estimated delivery times are displayed at checkout and may vary depending on service level and location. Please note that these are estimates and can be affected by weather, holidays, or carrier volume.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, and include all tags, manuals, accessories, and original, unaltered packaging. To start a return, please email us for approval. Items sent back without approval may be refused or returned to the sender. If any item is kept, its value will be deducted from the refund.

Non-returnable items include opened TVs, combos, or monitors 37″ or larger, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method. Please allow 5–7 business days for the credit to post. Shipping and handling are nonrefundable. If an item is used, incomplete, or not in its original condition, a 30% restocking fee may apply. Direct exchanges are not offered. To exchange an item, please purchase the replacement separately and return the original for a refund.

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.
