Server DDR5 Registered DIMM

This A-Tech module delivers 32 GB of DDR5 5600 memory with ECC and registered buffering for enterprise servers and workstations. It operates at the standard 1.10 V and uses a 1Rx4 single-rank layout on a 288-pin DIMM form factor. The CL46 latency rating matches the PC5-44800 data rate for stable throughput in multi-socket platforms.

Sustained-load behaviour

Error-correcting code and registered signalling keep data integrity intact during continuous workloads such as virtualisation, database serving or scientific compute. The single-rank x4 organisation reduces electrical loading on the memory controller, helping maintain the rated 5600 MT/s across all populated channels. Thermal output remains predictable at the JEDEC 1.1 V specification.

Installation notes

The module keys only into DDR5 RDIMM slots; it will not fit desktop or laptop DDR5 sockets. Seat the DIMM fully until the ejector clips lock, then follow the motherboard manual for correct channel population order. Common issues arise when mixing registered and unbuffered DIMMs or ignoring the platform’s qualified-vendor list.

Questions about this item

Does the 1.1 V DDR5 5600 module run hot or draw much power under continuous load?

At 1.10 V standard DDR5 voltage the 32 GB registered DIMM operates at typical server power levels; no extra cooling beyond normal chassis airflow is required.

My motherboard must support DDR5 RDIMM ECC at 5600 MHz and have a 288-pin slot — is that all I need?

Yes — a DDR5 server or workstation board with a 288-pin RDIMM slot, ECC support and a memory controller qualified for PC5-44800 is required; desktop or laptop boards will not work.

Can I mix this CL46 1Rx4 stick with older DDR5 4800 modules in the same server?

The module runs at DDR5 5600 CL46 1Rx4; the system will clock all installed DIMMs to the lowest common speed and timings, so older 4800 MHz sticks will force this module down to 4800 MHz.
