  • 2 V operation reduces power draw
  • 260-pin SODIMM form factor fits laptop slots

Capacity and Form Factor

This kit provides 64GB of DDR4 memory in two 32GB SODIMM modules. It uses the 260-pin SO-DIMM form factor designed for laptops and compact systems. The dual-rank 2Rx8 organisation enables dual-channel operation when both sticks are installed. Buyers needing ECC error correction or registered modules cannot use this product.

Installation Experience

The modules are standard unbuffered SODIMMs that insert into a 260-pin slot at 1.2V. No software configuration is required; the BIOS typically applies the rated 2933MHz CL21 timings automatically. Problems usually arise when a laptop firmware limits speed below the rated frequency or when mixing with existing memory of different rank or latency.

Sustained Load Behaviour

Under continuous workloads the memory maintains its specified 2933MHz data rate and CL21 latency. The 1.2V operating voltage keeps power draw consistent during extended multitasking or rendering sessions. Stability depends on the host platform's thermal management and memory controller capabilities.

Questions about this item

How can I confirm the kit is running at 2933MHz CL21 after installation?

Open Task Manager or CPU-Z and check the memory tab; it should show 2933MHz and CAS latency 21 for each 32GB module.

What exactly is included in the box and is anything else required?

The box contains two 260-pin DDR4 SO-DIMM modules totalling 64GB; no extra cables, brackets or software are needed.

Should I choose this 2Rx8 64GB kit or look for a different capacity?

Pick this 2Rx8 64GB kit if your laptop supports two 32GB modules and you want dual-channel bandwidth at 2933MHz.
