Server Memory Upgrade

This 4GB DDR3 1333MHz ECC registered DIMM replaces Samsung M393B5170 series modules in compatible servers and workstations. It delivers error-correcting code protection and registered buffering for stable operation in multi-module configurations. The single 4GB stick suits administrators expanding memory capacity on supported platforms.

Build and Connector Details

The module uses a 240-pin DIMM form factor with major-brand chips and a 2Rx4 rank organisation. Registered signalling reduces electrical load on the memory controller while ECC detects and corrects single-bit errors. Standard 1.5V DDR3 voltage ensures compatibility with DDR3 server boards that accept registered memory.

Compatibility Check

Verify that your system supports DDR3 1333MHz PC3-10600 ECC registered DIMMs and accepts 2Rx4 modules before ordering. Confirm the motherboard or server documentation lists the Samsung M393B5170 part numbers as qualified memory. This module is not for desktop boards that require unbuffered non-ECC memory or a different DDR generation.

Questions about this item

What speed does the DDR3 1333 ECC RDIMM run at and what bandwidth does that cap in practice?

The module operates at DDR3 1333 MHz, also labelled PC3-10600, which delivers a peak transfer rate of 10600 MB/s in a server or workstation.

What physical slot and pin count does this 240-pin DDR3 DIMM require to fit?

It needs a standard DDR3 DIMM slot with 240 pins; the registered design and 1.5 V voltage match server and workstation boards that accept ECC RDIMM modules.

How is the A-Tech 4GB DDR3 1333 ECC RDIMM installed and what step do people often get wrong?

Power down the system, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the ECC registered memory is detected at the correct speed.
