16GB DDR3L ECC Kit for Workstations

This kit provides 16GB of DDR3L memory across four 4GB unbuffered UDIMM modules. It is built for desktops, workstations and NAS systems that require error-correcting code support. The modules run at 1600MHz with a CAS latency of 11. Operating voltage is 1.35V.

240-Pin JEDEC Compliant Unbuffered DIMMs

Each module uses the standard 240-pin DDR3 form factor without a heat spreader. The design follows JEDEC and RoHS specifications for a warranty-safe upgrade. Unbuffered ECC organisation allows direct connection to the memory controller in compatible platforms. Black PCBs give a neutral appearance inside the chassis.

DDR3L 1600 CL11 Voltage and Platform Limits

The DDR3L interface caps transfer rates at 1600MT/s and requires a memory controller that supports 1.35V operation. ECC functionality only activates on platforms with an ECC-capable chipset and BIOS. Unbuffered topology limits the maximum usable rank count per channel compared to registered alternatives.

Questions about this item

Will this kit work in a standard desktop motherboard that takes 240-pin DDR3 DIMMs?

The modules are 240-pin DDR3L UDIMMs, so they fit any desktop board with DDR3 slots that accepts 1.35 V unbuffered ECC memory.

Do I need a CPU or chipset that specifically supports ECC for this memory to function?

Yes — the system must support unbuffered ECC; otherwise the modules will either run without error correction or may not post at all.

Can I mix these 4 GB sticks with existing 8 GB DDR3L modules to reach 32 GB total?

Mixing capacities is possible if the motherboard supports the total density and all modules share the same 1600 MHz CL11 1.35 V specification.
