Samsung M393A2K40CB1-CRC 16GB DDR4-2400 LP ECC REG

The Samsung M393A2K40CB1-CRC is a 16GB DDR4-2400 ECC registered server memory module for compatible systems that require 288-pin registered DDR4 RAM.

Recommended For

• Server administrators replacing a failed DIMM in a DDR4 server that supports 16GB ECC Registered RDIMMs and lists this module or its specifications as compatible.
• Homelab builders adding memory to a DDR4 server platform whose motherboard and processor explicitly support ECC Registered DIMMs.
• Operators of ECC-capable server or workstation systems who need a 16GB DDR4-2400 registered module for a platform-approved memory configuration.

Real-World Use Scenarios

• When a compatible DDR4 server is running short on memory, add this 16GB RDIMM to give virtual machines or server applications more room to run before memory pressure forces the host to reclaim or swap memory. The actual capacity and speed depend on the server’s supported configuration.
• For a Proxmox or similar homelab server, use the module to expand memory for a mix of virtual machines and containers. It can increase the memory available for those workloads, provided the motherboard and CPU support DDR4 registered ECC DIMMs.
• In an always-on server handling storage, backups, or other data-sensitive work, this ECC registered memory can provide error detection and correction when the system supports and enables ECC. It adds a memory-integrity feature; it does not replace backups or other data-protection measures.
• When replacing a failed DIMM or expanding an older DDR4 server, this module is a practical option if the server accepts 16GB DDR4-2400 RDIMMs and its memory rules allow the configuration. Check the system’s compatibility list and slot-population guidance first; registered DIMMs are not a general-purpose desktop RAM upgrade.
