64 GB DDR4 ECC SODIMM kit

This dual-channel kit supplies 64 GB of DDR4 ECC memory in two 32 GB modules. It targets microservers, mobile workstations and NAS appliances that require error-correcting SO-DIMMs. The unbuffered design suits platforms that do not accept registered DIMMs.

ECC protection and standard voltage

On-die ECC detects and corrects single-bit errors without host intervention, improving data integrity for always-on workloads. The modules operate at the JEDEC-standard 1.2 V, so no manual voltage tuning is required. CL21 latency at 2933 MHz keeps timing within baseline DDR4 specifications.

Dual-rank density and 260-pin form factor

Each 2Rx8 module presents two ranks per channel, giving the memory controller more open pages for multithreaded tasks. The 260-pin SO-DIMM footprint fits the standard laptop slot, but systems must explicitly support ECC unbuffered SODIMMs; machines limited to non-ECC or registered memory cannot use this kit.

Questions about this item

Will the 2Rx8 dual-rank modules need any firmware updates or replacement over time?

The modules are tested for reliable operation and carry a lifetime warranty; no firmware updates are required for the memory itself.

What limit appears first when the 64GB kit runs at 2933 MHz continuously?

The CAS latency of CL21 sets the timing boundary for sustained data throughput at the rated speed.

How much heat or power do the 1.2V SODIMMs produce during all-day workloads?

Operating at the standard 1.2V DDR4 voltage, the unbuffered modules generate minimal heat and draw low power even under constant load.
