  • Backward compatible with 2666, 2400 and 2133 MHz systems

Capacity and compatibility

This kit provides 32GB of DDR4 memory in two 16GB modules rated at 2933MHz CL21. The 260-pin SODIMM form factor fits laptops, all-in-one desktops and NAS devices that accept DDR4 ECC SO-DIMMs.

ECC and dual-channel benefits

ECC support adds single-bit error correction for data integrity in micro-servers, NAS units and point-of-sale systems. The matched pair enables dual-channel operation, doubling memory bandwidth compared with a single module of the same capacity.

Installation notes

Modules are unbuffered and operate at the standard 1.2V, so they install like any SODIMM without extra configuration. The only common issue is attempting to use them in non-ECC platforms that cannot recognise the error-correction circuitry, which will prevent the system from posting.

Questions about this item

Will the 260-pin ECC SODIMMs need any firmware updates or periodic replacement?

DDR4 ECC modules are solid-state with no moving parts or firmware; they do not require updates and are designed to last the life of the laptop or NAS under normal use.

What thermal or speed limit appears first when the 2933 MHz CL21 kit runs continuously in a NAS?

The JEDEC 1.2 V specification caps voltage, so sustained workloads hit the DDR4 2933 MT/s data-rate ceiling before any thermal throttle point is reached.

How much extra heat or power draw should I expect from the dual-rank 16 GB sticks at 1.2 V all day?

Each 16 GB module operates at the standard 1.2 V DDR4 voltage, adding only modest warmth and negligible power increase over lower-capacity SODIMMs in typical 24/7 NAS or laptop loads.
