Fujitsu Refurbished Memory
We stock refurbished Fujitsu memory for Primergy servers across DDR3, DDR4, and DDR5 generations. Capacities run from 2GB through 64GB per module, at speeds up to 4800MHz. Whether you're adding capacity to a virtualization host, replacing a failed DIMM, or keeping legacy Fujitsu-Siemens era servers running, we have Fujitsu server RAM ready to ship.
Every refurbished module is inspected and tested before shipping under our ISO 9001-certified quality management system. Orders ship from our warehouse in Denmark — with express delivery, your order will be delivered within 1–2 working days.

- DDR3, DDR4, and DDR5 server memory for Fujitsu Primergy generations
Refurbished Fujitsu DDR4 Memory
DDR4 makes up the largest part of our refurbished Fujitsu memory stock. It's the standard for Primergy M1 through M6 generation servers, at speeds from 2133MHz to 3200MHz and capacities from 8GB to 64GB. These registered ECC modules cover the broad middle of the Primergy lineup, from single-socket rack servers to dense dual-socket virtualization hosts.
Refurbished Fujitsu DDR3 Memory
For older Primergy S-generation servers, including systems from the Fujitsu-Siemens era, we stock refurbished DDR3 modules at 1333MHz and 1600MHz. These platforms are well past end of sale, and new DDR3 server memory is increasingly hard to source. Refurbished modules are often the most practical way to keep legacy systems running.
Refurbished Fujitsu DDR5 Memory
For the newest Primergy M7 generation, we stock a smaller selection of refurbished DDR5 modules at 4800MHz. DDR5 isn't backward compatible with DDR4 slots, so confirm your Primergy generation before ordering. Stock is more limited here, so contact our team if you need a specific capacity or quantity.
Fujitsu Memory Part Numbers and Compatibility
Fujitsu server memory uses S26361-F series part numbers, and matching the part number from your existing modules is the most reliable way to confirm a replacement. Primergy servers require registered ECC memory, and all modules in a system should match in type, speed, and rank for stable operation. Search by part number or server model in our Parts Finder, or use our Server Configurator to build a complete Primergy configuration with compatible memory.
Frequently Asked Questions
Which Fujitsu servers do you stock memory for? We stock refurbished memory for Primergy servers across multiple generations: DDR3 for older S-generation and Fujitsu-Siemens era systems, DDR4 for M1 through M6, and DDR5 for M7.
Can I use non-Fujitsu memory in a Primergy server? Primergy servers require registered ECC memory. Fujitsu-qualified modules with S26361-F part numbers are the safest choice, as unqualified modules may trigger BIOS warnings or run at reduced speed.
Can I mix different memory sizes or speeds? Mixing is technically possible in some Primergy configurations, but all modules will run at the speed of the slowest DIMM. For stable operation, match type, speed, and rank across the system.
How much can I save with refurbished Fujitsu memory? Up to 80% versus buying new, depending on the generation, capacity, and speed.
What's the warranty on refurbished Fujitsu memory? Every refurbished Fujitsu memory module comes with a 1-year warranty.
