Capacity 4GB

Speed DDR3L 1333 (PC3L 10600)

CAS Latency CL9

  • ECC protection guards data integrity in critical workloads
  • 35V DDR3L cuts power draw versus standard DDR3
  • 1333 MHz CL9 speed accelerates everyday tasks
  • 204-pin SODIMM fits microserver and workstation slots
  • Single-rank 1Rx8 layout eases dual-channel population

Microservers and NAS upgrade

This 4 GB DDR3L ECC SODIMM adds error-correcting memory to compatible microservers, mobile workstations and NAS appliances. It runs at 1333 MHz with CL9 latency and operates at 1.35 V or 1.5 V. The single-rank 1Rx8 module fits 204-pin slots and is unbuffered for broad platform support.

Replacing non-ECC or lower-capacity modules

The jump is worthwhile when your workload demands data integrity and the system board accepts DDR3L ECC unbuffered SODIMMs. Verify the manual for maximum capacity per slot and supported ranks before ordering. Systems limited to non-ECC memory cannot use this module.

Builders needing ECC on DDR3L platforms

Suits administrators upgrading supported microservers, NAS units or mobile workstations that require ECC unbuffered memory. Not for laptops or desktops lacking ECC support, nor for systems that only accept registered or load-reduced DIMMs. Buyers needing higher density per slot should look elsewhere.

Questions about this item

Does the 204-pin SO-DIMM fit a standard DDR3 laptop slot?

Yes, the 204-pin DDR3 SO-DIMM form factor matches the standard DDR3 laptop memory slot.

What is the correct way to seat the module so the ECC function works?

Align the notch with the slot key, press firmly until both side clips click, and verify the system BIOS recognises ECC mode.

Will the 1.35 V DDR3L chips need replacement if the laptop only supplies 1.5 V?

No, the module is rated for 1.35 V or 1.5 V operation, so it runs reliably at either voltage without degradation.
