Centon DRAM memory modules pair JEDEC-standard DDR DRAM with rigorously qualified components on a controlled bill of materials. Available in unbuffered (UDIMM), registered (RDIMM), and small-outline (SODIMM) form factors across DDR3, DDR4, and DDR5 generations, in ECC and non-ECC configurations to match server, workstation, industrial-PC, and embedded designs. Every build is locked to a fixed BOM with a new part number on any change, backed by SPD customization, post-production testing, and long-lifecycle supply for OEM and system-builder programs.

ECC (error-correcting code) modules add an extra DRAM device that lets the memory controller detect and correct single-bit errors on the fly — important for servers and any system where silent data corruption is unacceptable. Non-ECC modules omit that device and are typical in desktops and many embedded designs. Registered (buffered) memory — RDIMMs — places a register between the controller and the DRAM to reduce electrical load, allowing more modules and higher total density per channel; unbuffered memory (UDIMM and SODIMM) connects the controller directly for lower latency in smaller configurations. Your CPU and chipset dictate which type is supported, so the module must match the platform.

DDR (Double Data Rate) DRAM advances by generation — DDR3, DDR4, and DDR5. Each generation lowers operating voltage, raises bandwidth, and changes the physical key/notch, so modules are not cross-compatible between sockets: a board designed for one generation accepts only that generation. DDR5 also moves power management onto the module and splits each module into independent sub-channels. Choose the generation your CPU and motherboard support; the spec table on this page lists the generation, form factor, and pin count for each part.

When qualifying a module into a design, engineers typically confirm more than density: the JEDEC raw-card revision and DRAM organization, the SPD timing profile (which Centon can customize for your platform), module height and form factor for mechanical clearance, ECC and registered support on the target chipset, the operating temperature grade, and component-level BOM control so the module you qualify is the module you receive for the life of the program. Centon assigns a new part number on any BOM change and offers post-production burn-in and application validation, so a qualified build stays fixed.
