Server-grade DDR5 capacity

This 256 GB kit delivers two 128 GB registered DIMMs running at DDR5 4800 with a CAS latency of 40. It is built for servers that require ECC error correction and registered buffering to maintain data integrity under sustained workloads. The modules operate at 1.1 V and use a 2Rx4 organisation with major OEM DRAM chips.

Fits DDR5 RDIMM slots only

The 288-pin registered form factor requires a motherboard with DDR5 RDIMM slots and a platform that supports registered memory and ECC. Standard desktop boards that accept only unbuffered DIMMs cannot use this kit. Each module occupies a single DIMM slot, leaving remaining slots free for further capacity expansion.

No bundled software or accessories

The package contains only the two memory modules; there are no cables, adapters or management utilities included. Configuration is handled entirely through the server BIOS or firmware, so no extra software installation is required. Buyers needing mounting hardware or diagnostic tools must source them separately.

Questions about this item

How does the 1.1V operating voltage affect sustained thermal output?

The low 1.1V voltage reduces power draw per module, helping to limit heat generation during continuous server workloads.

What is the typical thermal behaviour under all-day load?

Registered DDR5 modules at 1.1V generally run cooler than higher-voltage alternatives, supporting stable 24/7 operation in airflow-managed chassis.

Which motherboard features are required for this kit to function?

A server platform with DDR5 RDIMM slots supporting ECC and registered memory topology is required for this 256GB kit to operate.
