IBM Refurbished Memory
We stock refurbished IBM RAM for IBM Power Systems and System x servers, from legacy DDR2 modules through DDR4. Whether you're adding capacity to a virtualization host, replacing a failed module, or keeping a legacy server running, we have refurbished IBM RAM ready to ship. If you need a module that isn't listed, our team can often source it.
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.
- Save up to 80% versus buying new
- Inspected and tested under our ISO 9001-certified quality management system
- 1-year warranty included

Refurbished IBM Power Systems Memory
Power Systems memory is identified by IBM feature codes, such as EM63, and many platforms use custom DIMMs (CDIMMs) rather than standard server modules. Power Systems also have memory plugging rules, so modules are installed in matched sets, and the right feature depends on your system generation. Whether you're running IBM i, AIX, or Linux, match the feature code or part number from your existing memory rather than choosing on capacity alone.
Refurbished IBM System x and BladeCenter Memory
IBM x86 servers use registered ECC modules (RDIMM) or load-reduced modules (LRDIMM), never both in the same server. For stable operation, match type, speed, and rank across the server, since mixed speeds run at the rate of the slowest module. We stock refurbished memory for System x and BladeCenter servers across several DDR generations.
Refurbished Memory for Legacy IBM Servers
For older IBM servers, including DDR2-era systems, we stock refurbished memory that is no longer sold new. These platforms are long past end of sale, and refurbished modules are often the only practical way to repair or upgrade them. Older servers can be strict about module type and voltage, so match the exact part number from your existing modules.
IBM Memory Part Numbers
IBM identifies a memory module by an FRU part number, such as 49Y1397 or 00LP680, and on Power Systems by a feature code such as EM63. Either can be used to find a replacement, and matching the number from your existing module or system documentation is the most reliable approach. Search by either in our Parts Finder, or use our Server Configurator to check compatible memory for your system.
Frequently Asked Questions
What's the difference between a used and a refurbished IBM memory module? A used module is sold as-is, without testing. Every module we sell is refurbished: inspected, tested, and covered by a 1-year warranty. We're an independent refurbisher, not part of IBM's own programs.
Can I use standard server DIMMs in an IBM Power system? Often not. Power Systems memory is qualified per platform and sold under IBM feature codes, and many platforms use custom DIMMs (CDIMMs) rather than standard modules. Match the feature code or FRU number from your existing memory, or contact our team with your system model.
Can I mix RDIMM and LRDIMM in an IBM x86 server? No. IBM x86 servers support either RDIMMs or LRDIMMs, not both at the same time.
How much does refurbished IBM server memory cost? Prices are listed on each product and depend on the generation, capacity, and speed. Refurbished IBM memory typically costs up to 80% less than new.
What's the warranty on refurbished IBM memory? Every refurbished IBM memory module comes with a 1-year warranty.
