4 GB DDR3L ECC UDIMM for Servers

This 4 GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35 V low voltage. It is built as an unbuffered ECC UDIMM with a single-rank 1Rx8 layout on a 240-pin form factor. The stick targets administrators who need to expand memory in servers or workstations that require ECC error correction and DDR3L signalling.

Suits ECC DDR3L platforms only

The module fits systems that explicitly support DDR3 or DDR3L ECC unbuffered DIMMs. It will not work in desktop or laptop computers that use non-ECC consumer memory, nor in servers that demand registered or load-reduced DIMMs. Buyers who need higher capacity per slot or registered signalling should look at different modules.

Single-rank 1Rx8 organisation

The 1Rx8 configuration places all chips on one rank with an x8 data width, which affects how the memory controller populates channels and reaches maximum supported capacity. Verify the platform’s rank and population rules before purchasing to ensure the module is recognised and operates at the rated 1600 MHz speed.

Questions about this item

How do I install the 240-pin DDR3L ECC UDIMM, and what step do people get wrong?

Align the notch on the module with the key in the slot, press firmly until both retention clips click, and verify the system is a DDR3 server or workstation — desktops and laptops will not accept this ECC unbuffered DIMM.

What maintenance or replacement will the 1Rx8 DDR3L module need later?

No scheduled maintenance is required; if a memory error appears, reseat the module and run a diagnostic — persistent faults mean the stick must be replaced.

What limit appears first when the CL11 1600 MHz kit runs under sustained load?

The 1.35 V DDR3L voltage ceiling and CL11 latency bound throughput before thermal throttling becomes a factor.
