A-Tech 4GB DDR3 1333MHz ECC RDIMM 1Rx4 240-Pin Server Memory

SKU CH-M2F0-783EQ

4GB DDR3 1333MHz ECC RDIMM 1Rx4 240-pin server memory module with CL9 latency and 1.5V operation

  • Capacity4GB
  • SpeedDDR3 1333 (PC3 10600)
  • CAS LatencyCL9
  • Voltage1.50V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 4GB capacity expands server memory headroom for heavier workloads
  • DDR3 1333MHz speed matches PC3-10600 system bus timing
  • ECC registered design detects and corrects single-bit data errors
  • 1Rx4 single-rank layout keeps electrical loading low per channel
  • 5V standard voltage ensures compatibility with DDR3 server platforms

Server Memory Replacement

A-Tech supplies this 4GB DDR3 1333MHz ECC RDIMM as a direct replacement for Micron MT18JSF51272PZ-1G4D1BB. The module uses registered signalling and a 1Rx4 layout on 240-Pin DIMM form factor. It operates at 1.5V standard voltage with CL9 latency for server and workstation platforms.

Suits ECC Registered Slots Only

This module fits systems that require DDR3 ECC registered memory at 1333MHz. It will not work in desktop boards that accept only unbuffered non-ECC DIMMs. Buyers who need higher capacity per slot or a different voltage should look at other modules.

Registered ECC DDR3 1333MHz

The single specification that decides fit is the registered ECC DDR3 1333MHz interface. Only platforms specifying DDR3 RDIMM at this speed and 1.5V will accept the module. Verify your system documentation lists this exact configuration before ordering.

商品問答

Does this module need a server motherboard that supports DDR3 1333MHz ECC registered DIMMs?

Yes — it is a DDR3 1333MHz ECC RDIMM, so the board must accept registered DDR3 memory with ECC at that speed.

Can I mix this 1Rx4 registered stick with older unbuffered DDR3 DIMMs in the same system?

No — registered and unbuffered DDR3 cannot be used together; all slots must use registered modules for the system to operate.

How do I confirm the module is running at PC3-10600 with ECC active after installation?

Check the BIOS memory information or OS tools — they should show 1333MHz speed, 1.5V voltage, and ECC enabled for this 240-pin DIMM.
