A-Tech 4GB DDR3 1333 ECC UDIMM

This module is a 4 GB DDR3 ECC unbuffered DIMM built for servers and workstations that require error-correcting memory. It operates at 1333 MHz with a standard 1.5 V supply and uses a 240-pin form factor.

DDR3 1333 speed and ECC unbuffered limits

The PC3-10600 rating sets a maximum data rate of 1333 MT/s, so the module cannot run faster than the platform’s memory controller allows. ECC unbuffered designs also require a motherboard that supports ECC UDIMMs; registered or fully buffered boards will not accept this module.

2Rx8 dual-rank organisation decides fit

The 2Rx8 dual-rank x8 layout determines how the memory controller addresses the chips. Systems limited to single-rank modules or to a different rank configuration will not recognise the full capacity or may fail to boot.

Questions about this item

Should I choose the 4GB 2Rx8 DDR3 1333 ECC UDIMM or a different capacity for my server?

This module is a single 4GB stick with a 2Rx8 dual-rank layout. Select it when your system requires ECC unbuffered DDR3 at 1333 MHz and has an open 240-pin DIMM slot.

What does the DDR3 1333 (PC3-10600) speed rating mean once the module is installed?

The memory operates at 1333 MHz with standard 1.5V DDR3 voltage, providing ECC error correction for data integrity in server and workstation workloads.

Is the PC3-10600E interface compatible with my motherboard's memory slots?

The module uses a 240-pin DDR3 DIMM form factor with ECC unbuffered signalling. It fits only DDR3 server or workstation boards that support ECC UDIMM; it will not work in desktop or laptop systems.
