Samsung's M425R4GA3BB0-CWMOL delivers 32GB of DDR5 capacity at 4800 MT/s in a compact 262-pin SO-DIMM form factor, meeting the PC5-38400 speed standard. This configuration addresses the memory density and throughput demands of modern server refresh cycles, where IT procurement teams are consolidating socket counts while maintaining or exceeding aggregate bandwidth to CPU cores.

The module operates at 1.1V with a CAS latency of 40 and symmetric timing across its 2Rx8 rank configuration, derived from Samsung's proven 16Gb die architecture. The M425R4GA3BB0-CWMOL is compliant with JEDEC DDR5 specifications and carries on-die error-correction circuitry (ODECC) built into the DRAM itself, meaning system administrators and infrastructure engineers can deploy this unbuffered SO-DIMM into platforms that leverage single-error-correction logic at the memory controller without requiring registered modules or external parity schemes. This approach reduces latency overhead compared to buffered alternatives, a trade-off that matters in latency-sensitive workloads.

Samsung engineered this part for the thermal envelope of modern compact servers and edge appliances, with an operating temperature range spanning 0°C to 85°C. The M425R4GA3BB0-CWMOL integrates cleanly into systems where space constraints or power budgets prohibit larger RDIMM deployments—think high-density 2U/1U platforms, storage nodes running deduplicated workloads, or AI inference clusters where memory bandwidth per watt becomes the limiting constraint. Data centre architects and procurement managers tasked with refreshing 3- to 5-year-old infrastructure often encounter mixed DDR4/DDR5 transitions; this Samsung module bridges that gap for facilities moving from older SO-DIMM inventory into next-generation platforms without oversizing individual sockets.

The module's 64-bit data bus width, split across two 32-bit subchannels, ensures balanced load distribution on dual-channel memory controllers. RoHS compliance and Samsung's quality assurance processes make the M425R4GA3BB0-CWMOL suitable for regulated environments—financial data centres, healthcare systems, and telecom infrastructure where supply-chain traceability and material certifications are non-negotiable. IT managers responsible for memory procurement in such sectors will find this part's documentation and certifications straightforward to audit and archive.

When configuring a server node or evaluating memory tier options for a refresh programme, the M425R4GA3BB0-CWMOL's combination of capacity, speed, and form factor delivers a flexible middle ground: not the maximum density of 48GB or 64GB UDIMMs, but sufficient to avoid socket multiplication in two-socket or four-socket platforms. Samsung's reputation for consistency in this category means replacement and field-upgrade workflows are simpler than sourcing from lesser-known vendors.
