M393A1K43DB1-CVF Samsung 1x8GB DDR4 RDIMM ECC RAM

Enterprise DDR4 ECC Registered RDIMM memory for OEM server maintenance with the M393A1K43DB1-CVF

The M393A1K43DB1-CVF is a Samsung DDR4 RDIMM designed for platform-stable OEM server upgrades and repairs across Intel Xeon and AMD EPYC generations that depend on registered DIMM signaling. In 2-socket compute nodes and dense 1U/2U systems, this 8GB module provides predictable memory behavior under sustained virtualization and database pressure, where ECC and buffering reduce the risk of data corruption and timing instability.

With 2933MT/s operation, the M393A1K43DB1-CVF aligns memory bandwidth to modern CPU memory controllers so PCIe-attached accelerators and NVMe storage are not starved by inefficient DRAM throughput. The 288-pin low-profile form factor supports clearance constraints around air shrouds, risers, and high-TDP CPU heatsinks, while the 1.2V operating point helps maintain thermal and power budgets in tightly packed racks. Single-rank x8 organization supports broad platform compatibility when expanding capacity in homogeneous DIMM populations.

Why Choose the M393A1K43DB1-CVF?

The M393A1K43DB1-CVF is selected when architectural reliability matters more than oversized capacity: ECC Registered design improves signal integrity at scale, enabling consistent performance per rack unit and reducing intermittent memory faults that disrupt clustered services. It is a pragmatic choice for lifecycle extension, spare strategy standardization, and incremental scaling in DDR4 RDIMM fleets.

Samsung engineers server DRAM for high duty-cycle operation, emphasizing qualification discipline, stable timing margins, and predictable interoperability with enterprise BIOS and memory training routines. This approach supports data centre standards for serviceability, controlled change management, and long-term platform continuity.

Key Applications:

• OEM server upgrades and repairs
• Virtualization and private cloud hosts
• Enterprise databases and middleware
• File and infrastructure services
• Capacity expansion in low-profile servers
