Capacity and Kit Configuration

This kit provides 16GB of DDR4 memory in a matched pair of 8GB modules. It is built for desktop PCs, workstations, servers and NAS systems that require ECC data integrity.

Platform Fit and Electrical Requirements

The modules use the standard 288-pin UDIMM form factor and run at 1.2V. They install in any board that accepts unbuffered DDR4 ECC memory and will operate at 2933MHz or downshift to 2133MHz, 2400MHz or 2666MHz as needed.

Speed, Latency and Headroom

Rated at PC4-23400 with a CAS latency of 21, the kit delivers 2933MHz throughput for multi-tasking workloads and large file handling. ECC correction protects data accuracy, while the dual-channel layout maximises memory bandwidth for sustained compute tasks.

Questions sur cet article

What is the maximum speed this DDR4 2933MHz kit will reach under sustained load?

The modules run at 2933MHz (PC4-23400) with CL21 latency at 1.2V; JEDEC compliance guarantees that rated speed is maintained during continuous operation.

How much heat and noise do these unbuffered ECC DIMMs produce when running all day?

No heat spreader is fitted and the 1.2V DDR4 design keeps thermal output low; the modules are silent because they have no moving parts.

What motherboard feature must I already have to use the ECC function on this 16GB kit?

Your board must support ECC on unbuffered 288-pin DDR4 slots; without that the modules will still run but error correction will be inactive.
