Capacity and purpose

This kit provides 16GB of DDR4 memory across two 8GB modules. It is intended for workstations, servers and NAS systems that require error-correcting code support. The unbuffered design suits desktop-class boards that accept ECC UDIMMs.

Speed and standard limits

The modules run at 2400MHz with a CAS latency of 17 and operate at 1.2V. They conform to the PC4-19200 JEDEC specification and are backward compatible with 2133MHz systems. No higher frequencies or lower latencies are supported by this kit.

Build and connectors

Each stick uses a standard 288-pin UDIMM edge connector and has no heat spreader. The low-profile black PCB fits tight spaces in rackmount or small-form-factor chassis. Installation follows the usual DIMM slot procedure without extra clearance concerns.

Questions about this item

Will this ECC memory work in my desktop PC?

The modules are unbuffered ECC UDIMMs built to JEDEC DDR4 2400 standards and listed as compatible with desktop PCs, workstations, servers and NAS systems, so they will work if your motherboard supports DDR4 ECC unbuffered memory.

Can I run the kit at 2133 MHz if my board does not support 2400 MHz?

Yes, the modules are backward compatible with 2133 MHz and will automatically down-clock to match the board's maximum supported speed.

Do I need a heat spreader for these sticks?

No, the modules ship without a heat spreader and operate at the standard 1.2 V; typical desktop airflow is sufficient for normal workloads.
