Server memory kit for ECC workloads

This 32 GB dual-channel kit contains two 16 GB DDR4 2666 registered DIMMs with ECC and a CAS latency of CL19. It is built for servers and workstations that require registered memory and will not function in desktop or laptop platforms.

Standard voltage and registered buffering

Each module operates at 1.2 V and uses a 288-pin registered design to reduce electrical load on the memory controller. The single-rank x4 organisation helps maintain signal integrity in multi-DIMM configurations typical of server boards.

Lifetime warranty and US-based support

A-Tech backs the kit with a lifetime warranty and provides complimentary United States-based technical support before, during and after purchase. All modules undergo quality-assurance testing to verify reliable operation in compatible systems.

Spurningar um þessa vöru

How do I install these 288-pin DDR4 RDIMM modules in the correct channels?

Power down the server, open the chassis, and insert each 16 GB module into the DIMM slots specified by the motherboard manual for dual-channel operation; the notch on the 288-pin edge connector keys the module so it can only seat one way.

Will the ECC chips or registered buffer need replacement after a certain period?

The ECC RDIMM uses major-brand DRAM chips and an on-board register; both are solid-state with no moving parts, so no scheduled component replacement is required under normal operating conditions.

At what point does the CL19 latency at 2666 MHz become the bottleneck during sustained workloads?

Under continuous heavy memory traffic the fixed CL19 timing at 2666 MHz sets the minimum access delay, so the CAS latency itself is the first limit encountered before bandwidth saturation.
