Crucial CT16G4RFD8266

Overview

The Crucial CT16G4RFD8266 is a 16 GB DDR4 registered memory module designed specifically for servers that require reliable uptime and steady data throughput. Operating at 2666 MHz, it provides the bandwidth necessary for Intel Xeon-based systems to efficiently handle virtualization, database management, and other demanding workloads involving large data sets. Its error-correcting code (ECC) ensures data integrity by detecting and correcting common memory errors before they affect system performance.

Key features

• Registered ECC memory that safeguards against data corruption, enhancing system stability for critical applications
• Dual-rank architecture that improves memory access efficiency by allowing interleaved operations, reducing latency under heavy multitasking
• Low voltage operation at 1.20 V, which reduces power consumption while maintaining performance suitable for modern server chipsets
• Compatible with Intel Xeon processors and most OEM server motherboards, making it a versatile upgrade option
• Simple installation process that fits into standard 288-pin RDIMM slots, enabling quick capacity expansion without replacing existing hardware

Connectivity and compatibility

This memory module is engineered to work seamlessly with Intel Xeon processors and is compatible with a wide range of OEM server boards that support DDR4 RDIMM memory. Its registered design ensures stable communication with the memory controller, which is essential for maintaining performance in multi-processor server environments.

Ideal uses and environments

The Crucial CT16G4RFD8266 fits well in data centers, enterprise servers, and small business file servers where consistent memory performance and data accuracy are critical. It supports workloads such as virtualization, large database operations, and analytics tasks that demand reliable and efficient memory access. This module is a strong choice for IT professionals looking to upgrade server memory capacity without overhauling their entire system.

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. Once your order ships, you’ll receive a tracking number for real-time updates from pickup to final delivery.

Providing an accurate shipping address helps prevent delays, and changes may be limited once the order has been dispatched. P.O. boxes are supported only when permitted by the selected carrier. Packaging and handoff are optimized to protect items during transit, though oversized or high-weight products may require special handling.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, 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; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement 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.
