ECC DDR5 SODIMM kit for mobile workstations

This 64GB kit contains two 32GB DDR5 4800 SODIMM modules with ECC and a CAS latency of CL40. It is built for laptops, microservers and NAS units that accept 262-pin unbuffered ECC memory. The dual-rank 2Rx8 organisation and 1.1V operation follow the JEDEC DDR5 standard.

Dual-channel kit with on-die error correction

The two modules are matched for dual-channel operation, doubling throughput compared with a single stick. ECC circuitry detects and corrects single-bit errors inside the DRAM array, protecting data integrity in always-on servers and workstations without requiring registered or buffered signalling.

64GB capacity for virtualised workloads

Sixty-four gigabytes lets a mobile workstation or microserver run multiple virtual machines, large datasets or ZFS caches simultaneously. The 4800 MT/s speed and CL40 latency deliver mainstream DDR5 bandwidth, while the fixed 1.1V voltage keeps power draw predictable. Systems limited to lower speeds or non-ECC slots cannot use this kit.

Questions about this item

Will the dual-rank 2Rx8 modules need any firmware updates or special handling when I add them later?

The kit uses standard JEDEC DDR5 4800 modules at 1.1 V; no firmware updates are required and the modules are handled like any other SODIMM.

What limit appears first when the memory runs at full 4800 MHz CL40 continuously?

Sustained operation is constrained by the JEDEC 1.1 V voltage ceiling and the CL40 latency ceiling; the modules have no heat spreader so thermal headroom is the practical limit.

How much heat and power draw should I expect from the 64 GB kit running all day in a microserver?

Each 32 GB module operates at the standard 1.1 V DDR5 voltage with no heat spreader, so power draw stays at the JEDEC baseline and heat output is low for continuous use.
