Buying Guide & FAQs

Enterprise Memory You Can Rely On

ECC (Error-Correcting Code) RAM is the memory standard of choice for servers, workstations, and any environment where data integrity is non-negotiable. Unlike standard consumer modules, ECC memory detects and corrects single-bit errors on the fly — reducing the risk of crashes, data corruption, and unplanned downtime.

Our refurbished ECC modules are sourced from decommissioned enterprise systems, thoroughly tested at our UK facility, and supplied with a 12-month warranty. Whether you're expanding an existing server, upgrading a workstation, or sourcing memory in bulk, our range covers the most widely used platforms on the market — including Dell PowerEdge, HPE ProLiant, and Lenovo servers and workstations.

What's in Our ECC RAM Range

  • Registered (RDIMM) and Load-Reduced (LRDIMM) DDR4 modules for rack and tower servers
  • Unbuffered (UDIMM) ECC DDR4 and DDR3 for workstations and entry-level platforms
  • A range of capacities — from 8GB single modules to high-density 64GB LRDIMMs
  • Compatibility with Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and HP Z-series workstations
  • Mixed-lot and bulk quantities available for data centre and IT reseller requirements
  • All modules supplied with original heatspreaders where applicable

Frequently Asked Questions

What is ECC RAM and do I need it?

ECC (Error-Correcting Code) RAM automatically detects and corrects memory errors in real time. It's a requirement for most server platforms and is strongly recommended for workstations running mission-critical applications, virtualisation, or large datasets. If your system's motherboard or CPU supports ECC, it's almost always worth using it.

What's the difference between RDIMM, LRDIMM, and UDIMM?

RDIMMs (Registered DIMMs) include a register between the DRAM chips and the memory controller, improving stability at higher capacities — standard in most rack servers. LRDIMMs (Load-Reduced DIMMs) go further, using a memory buffer to allow even higher density configurations. UDIMMs are unbuffered and typically used in workstations or entry-level servers where the memory controller handles the load directly.

Will refurbished ECC RAM work in my server or workstation?

In the vast majority of cases, yes — provided the module type, generation (DDR3/DDR4), speed, and rank configuration match your platform's specifications. If you're unsure, contact our team with your server model and current memory configuration and we'll identify the right modules for you.

Do you offer bulk pricing for larger memory orders?

Yes. We regularly supply ECC RAM in quantity to IT resellers, system integrators, and data centre teams. Get in touch directly for volume pricing and availability — we're happy to quote on mixed lots or specific module requirements.

What warranty comes with refurbished ECC RAM?

All ECC memory sold by Compuwyze includes a 12-month warranty. If a module develops a fault within this period, we'll arrange a replacement or refund — straightforwardly and without unnecessary delay.
