Capacity and purpose

This kit provides 64GB of DDR4 memory across eight 8GB modules. It is built for workstations, servers and NAS systems that require error-correcting code reliability. The modules run at 2400MHz with CL17 latency and operate at 1.2V. They are unbuffered 288-pin UDIMMs suitable for compatible desktop platforms.

Thermals noise and power

Operating at 1.2V keeps power draw low for a fully populated eight-module configuration. No heat spreaders are fitted, so airflow across the bare PCBs handles thermal management. The JEDEC-standard voltage and timings avoid extra stress on the memory controller. Silent operation is inherent because there are no active cooling components.

Build and connectivity

Each module uses a black PCB with 288 gold-plated edge contacts and no RGB lighting. The unbuffered ECC design plugs directly into standard DDR4 UDIMM slots without registration delays. Backward compatibility with 2133MHz systems allows use in older platforms. The eight-module layout fills most consumer boards completely, so verify slot count before installation.

Soalan tentang produk ini

Will this 64GB kit work in a standard desktop motherboard that only supports non-ECC memory?

The modules are ECC unbuffered; many consumer desktop boards ignore the ECC function but some will not boot with ECC DIMMs installed. Check your motherboard manual for explicit ECC support before purchasing.

Can I mix these 2400MHz modules with existing 2133MHz DDR4 sticks?

Yes, the kit is backward compatible with 2133MHz operation. When mixed, all modules will run at the lower 2133MHz speed and the loosest timings present in the system.

Does the kit require a heat spreader or active cooling for sustained workloads?

The modules ship without a heat spreader and operate at the standard 1.2V JEDEC voltage. For typical workstation or NAS loads, case airflow is usually sufficient; monitor temperatures if the chassis has restricted airflow.
