Server Memory Kit

This A-Tech kit provides 32GB of DDR4 ECC registered memory across four 8GB modules. It is built for servers and workstations that require error-correcting registered DIMMs for data integrity. The single-rank 1Rx8 organisation helps maintain signal quality on dense memory channels. This product is not compatible with standard desktop or laptop computers.

Build Integration

Each module uses the 288-pin DDR4 DIMM form factor and operates at the standard 1.2V voltage. The quad-channel kit populates four slots to maximise memory bandwidth on supported server platforms. Registered buffering reduces electrical load on the memory controller, allowing larger total capacities. ECC functionality corrects single-bit errors to protect critical workloads.

Upgrade Context

The kit replaces non-ECC or unbuffered memory in systems that mandate registered ECC DIMMs. Moving from lower-speed DDR4 to the 2666 MHz CL19 specification improves throughput for memory-bound applications. The jump is worthwhile when your server board supports DDR4 2666 registered memory and you need the full 32GB capacity for virtualisation or database tasks.

Questions about this item

What CAS latency does this DDR4 2666 kit run at when all four modules are fully populated?

The kit runs at CL19 CAS latency when all four 8 GB modules are installed in the server or workstation.

How much heat and power should I expect from this 1.2 V registered ECC kit during continuous operation?

Each module operates at the standard DDR4 1.20 V, so total power draw stays within normal registered DIMM limits and active cooling in a server chassis handles the heat.

Which motherboard feature must my system already have to use this 288-pin RDIMM kit?

The board must provide DDR4 registered DIMM slots that support ECC RDIMM modules; standard desktop or laptop memory controllers will not work.
