4GB DDR3 ECC RDIMM for Servers

This 4GB DDR3 1333MHz PC3-10600 ECC Registered DIMM targets server and workstation administrators who need dependable registered memory with error correction. It serves as a compatible replacement for the Samsung M392B5273CH0-CH9 module and uses a Samsung chipset. The single module delivers 4GB capacity at standard DDR3 voltage.

Check DIMM Slots and Registered Support

Before ordering, confirm that your system accepts DDR3 240-pin Registered DIMMs and supports ECC functionality. The module operates at 1.50V with CL9 latency and a 2Rx8 rank configuration. Verify the maximum supported memory per slot and total capacity in your platform documentation to ensure compatibility.

Upgrade from Non-ECC or Lower Capacity

This module replaces non-ECC unbuffered DIMMs or smaller registered modules in compatible servers. The jump is worthwhile when workloads demand error correction for data integrity or when registered signalling is required for large memory configurations. It upgrades systems currently limited by missing ECC or insufficient registered memory slots.

Questions about this item

Does the 240-pin DDR3 RDIMM ship as a single 4GB stick or do I need to order multiple modules?

The listing is for one 4GB module (1x 4GB) so you receive a single stick; add more if your server needs additional capacity.

Should I pick the PC3-10600 CL9 1.5V version or a different speed for my Samsung M392B5273CH0-CH9 replacement?

Choose this exact PC3-10600 CL9 1.5V registered ECC module; it matches the Samsung part number and voltage specification.

What does the 1333MHz rating actually deliver once the RDIMM is installed in a server?

The module runs at DDR3 1333 MT/s with CL9 latency, providing registered ECC bandwidth of PC3-10600 for compatible server workloads.
