Samsung 4GB DDR3 1333 ECC Registered Memory Module

The Samsung M393B5273DH0-YH9 is a memory module for servers that provides 4GB of DDR3 capacity at a data rate of 1333 Mbps. It combines error correcting code with a registered buffer to keep data transfers accurate and stable, making it a solid choice for environments where uptime cannot be compromised.

The module can run at 1.5 V or 1.35 V, so it aligns with power profiles across different server generations. A two rank structure with x8 organization improves compatibility with a wide range of Intel and AMD DDR3 boards, and the standard 240 pin RDIMM interface means installation is as simple as inserting the stick and powering up.

Virtualization hosts, database servers, and file servers that need an affordable capacity boost can use this module to expand memory without overhauling existing hardware. The onboard register maintains signal integrity even when every slot on the motherboard is populated, allowing dense, multi module builds to stay reliable under heavy load.

Highlights:

• 4GB DDR3 module that operates at 1333 Mbps
• Error correcting code with 8 bit parity for data integrity
• Registered design that stabilizes clock, command, and control signals
• Dual voltage support at 1.5 V and 1.35 V
• Two rank, x8 organization for broad platform compatibility
• Standard 240 pin RDIMM interface for DDR3 server sockets
