Server DDR3 ECC RDIMM Upgrade

This A-Tech module delivers 4 GB of DDR3 1333 MHz registered ECC memory for compatible servers and workstations. It is built as a direct replacement for the Samsung M393B5270DH0-CH9Q9 part and uses Samsung chipset components throughout.

240 Pin Registered Form Factor

The 240 pin DIMM design requires a motherboard slot that accepts registered DDR3 modules and cannot be used in standard unbuffered desktop boards. ECC and register circuitry add data integrity for mission critical workloads while the 1.5 V operation matches the DDR3 standard voltage specification.

Lifetime Warranty And US Support

Every module undergoes quality assurance testing before shipment to confirm reliable operation in qualified systems. A-Tech backs the product with a lifetime warranty and provides complimentary United States based technical support for installation and troubleshooting assistance.

Questions about this item

What DDR3 speed and PC3 rating does this 4GB ECC RDIMM run at?

The module operates at 1333 MHz with a PC3-10600 rating and CL9 latency.

How many pins does the DIMM have and what form factor is it?

It is a 240-pin DDR3 DIMM; the 262-pin figure in the spec sheet refers to SODIMM and does not apply here.

What voltage must the server supply and is the module registered?

The DIMM requires 1.5 V and is a registered ECC RDIMM (1Rx4) so the motherboard must support registered memory.
