Server-grade DDR5 ECC RDIMM kit

This 256GB quad-channel kit contains four 64GB registered DIMMs built for DDR5 server and workstation platforms only. It will not fit desktop or laptop systems. Each module uses a 288-pin form factor with ECC error correction for data integrity in critical workloads.

Thermals power and acoustics

The modules operate at the standard DDR5 voltage of 1.1V, keeping power draw low for high-density server configurations. Passive cooling relies on chassis airflow; no fans or active cooling are included. Acoustic impact is negligible in typical rack or workstation environments.

Registered ECC with dual-rank x4 organisation

CL46 latency at 5600 MT/s (PC5-44800) defines the timing envelope for memory-controller compatibility. The 2Rx4 rank structure and EC8 registered buffer determine whether your platform can populate all four slots at rated speed.

Spurningar um þessa vöru

How do I install these 288-pin DDR5 RDIMMs in the correct quad-channel order?

Insert each 64 GB module into the slots your motherboard manual designates for quad-channel population, pressing straight down until the latches click; the registered buffer adds a slight delay before the POST memory check completes.

When will the ECC registered DIMMs need replacement?

The modules carry a lifetime warranty and have no user-serviceable parts; replacement is only required if a memory test reports uncorrectable errors on a specific 64 GB stick.

At what point does the CL46 latency at 5600 MT/s become the bottleneck under sustained load?

The CAS 46 timing at 1.10 V is the first fixed limit; once the memory controller saturates the 44800 MB/s bandwidth, further throughput gains require higher-frequency or lower-latency DIMMs.
