SAMSUNG M393A4K40CB1-CRC 32GB DDR4 2400 RDIMM
The Samsung M393A4K40CB1-CRC is a 32GB DDR4-2400 ECC registered DIMM (RDIMM) built for enterprise servers, data centers, and virtualization or database workloads. It suits B2B buyers sourcing proven, JEDEC-standard memory for platform refreshes or capacity expansion on Intel- and AMD-based server platforms that accept DDR4 RDIMMs. Practical note: confirm your platform’s maximum supported data rate, as this module will typically down-clock on hosts rated below 2400 MT/s.

Good to know
- As a DDR4 RDIMM, this module is not interchangeable with DDR5 or with LRDIMMs/U DIMMs — RDIMMs and LRDIMMs should not be mixed in the same system; verify your server’s qualified memory list (QVL) and population rules before ordering. Dual-rank modules may reduce the number of DIMMs usable per channel at higher populations on some platforms.
- At 2400 MT/s / PC4-19200R, this sits at the entry tier of the DDR4 RDIMM family (below 2666, 2933, and 3200 MT/s grades); it remains a cost-effective fit for legacy-generation hosts where the CPU memory controller caps at 2400 MT/s anyway.
- Buying tip: for virtualization hosts and cache tiers, populate identical modules (same capacity, rank, and speed grade) across channels for consistent, predictable memory performance — we recommend purchasing in matched sets for symmetric channel population.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
