96 GB DDR5 ECC RDIMM for Servers

This A-Tech module delivers 96 GB of DDR5 5600 registered ECC memory in a single 288-pin DIMM. It is built for server and workstation platforms that require error-correcting, registered modules to maintain data integrity under heavy workloads. The 2Rx4 organisation with Samsung chipset provides high-density capacity for memory-intensive applications.

Fits DDR5 RDIMM Slots with 1.1 V Operation

The module installs in standard DDR5 288-pin RDIMM slots and operates at the DDR5 standard voltage of 1.10 V. Registered signalling reduces electrical load on the memory controller, freeing headroom for larger memory configurations in multi-socket systems. Verify your platform supports 96 GB RDIMM density and DDR5 5600 speeds before installation.

Sustained Load Stability

Error-correcting code detects and corrects single-bit errors in real time, preventing data corruption during continuous operation. Registered buffering stabilises command and address signals across all ranks, maintaining consistent timing at CL40 latency during prolonged compute tasks. The 1.1 V operation keeps power draw predictable for dense server deployments.

Questions about this item

What CAS latency limits sustained throughput on this 96 GB DDR5 5600 RDIMM?

The module runs at CL40, so each request waits 40 cycles before data moves; under sustained load that latency becomes the first bottleneck before bandwidth saturates.

How much heat and power does a 1.1 V registered DIMM produce when it runs all day?

At the standard 1.1 V DDR5 voltage the module draws minimal power and generates low heat; the registered buffer adds slight overhead but stays within typical server thermal envelopes.

What motherboard slot and memory controller must I already have for this 288-pin DDR5 RDIMM to work?

You need a DDR5-capable server or workstation board with a 288-pin RDIMM slot and a memory controller that supports registered ECC modules at 5600 MT/s.
