4GB DDR3L ECC RDIMM for servers

This 4 GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35 V operation. It is a registered ECC DIMM built for server and workstation platforms that require error-correcting memory.

Verify DDR3L registered ECC support

Check that your system accepts DDR3L registered ECC RDIMMs at 1.35 V before ordering. The module uses a 240-pin DIMM form factor and a 1Rx4 organisation, so the motherboard must support this exact configuration.

Low-voltage operation reduces heat

Running at 1.35 V lowers power draw and thermal output compared with standard 1.5 V DDR3. Registered buffering adds minimal overhead while maintaining signal integrity under sustained server workloads.

Questions about this item

What comes in the package and what else is needed to install it?

One 4GB DDR3L 1600MHz ECC registered DIMM is supplied. No extra parts are required if the server has a free 240-pin slot and supports DDR3L 1.35V registered memory.

How do I decide between this 4GB module and a higher-capacity option?

Choose this 4GB stick when the system has limited DIMM slots or only needs a small capacity increase. Add multiple 4GB modules to reach larger totals while keeping the same 1Rx4 rank configuration.

What does the 1600 MHz rating mean once the module is running in a server?

The module operates at 1600 MHz with CL11 timing at 1.35V, delivering DDR3L PC3-12800 data rates with registered ECC buffering for error-corrected stability.
