High-capacity DDR4 ECC SODIMM for servers

This 32GB DDR4 2666MHz module targets administrators upgrading workstation or server laptops that require error-correcting memory. The unbuffered design fits standard 260-pin SO-DIMM slots while the CL19 timing and 1.20V voltage match mainstream DDR4 specifications. Buyers needing non-ECC or lower-capacity sticks should look elsewhere.

Fits 260-pin DDR4 SO-DIMM slots with ECC support

The module installs directly into compatible laptop or compact server boards that accept unbuffered ECC SO-DIMMs. It frees the system from single-channel constraints by delivering a full 32GB in one slot, leaving additional sockets open for further expansion. Systems without ECC capability in the chipset or BIOS cannot use the error-correction function.

Sustained operation at standard DDR4 voltage

Continuous workloads run at the rated 2666MHz speed and 1.20V without elevated power draw. The ECC circuitry corrects single-bit errors during extended compute sessions, reducing silent data corruption. Thermal output remains consistent with typical DDR4 SO-DIMM behaviour under prolonged load.

Questions about this item

Will the CL19 latency limit throughput during sustained workloads?

CL19 is the rated CAS latency at 2666 MHz; sustained throughput depends on the memory controller and workload profile.

How much heat does the 1.20 V module produce when running all day?

At 1.20 V standard DDR4 voltage the module generates typical low heat for an unbuffered ECC SODIMM.

Does my laptop need a 260-pin DDR4 slot and ECC support in the BIOS?

Yes, it requires a 260-pin DDR4 SO-DIMM slot and a platform that enables ECC on unbuffered memory.
