Samsung M393B5273DH0-YK0 4GB DDR3-1600 ECC Registered RAM | Server Memory

Keep critical workloads running with Samsung M393B5273DH0-YK0, a 4 GB DDR3 registered module specified for server-class platforms that require ECC protection and consistent memory behavior. Rated at 1,600 MHz as PC3L-12800R, it supports dependable throughput for virtualization hosts, file services, and legacy enterprise systems that still depend on DDR3 infrastructure. This module uses a 2Rx8 organization and low-voltage DDR3L signaling to help balance performance and efficiency in compatible systems. ECC support adds a layer of memory integrity that matters when downtime, data corruption, or intermittent faults are not acceptable. For teams extending the life of proven hardware, this is the kind of component that preserves platform stability without forcing a broader refresh. Choose this module when compatibility, validated memory behavior, and low-power operation matter more than headline capacity. It is a practical fit for server maintenance, spare-part stocking, and targeted upgrades where the right memory specification is more valuable than a generic replacement.
