8 GB DDR4 3200 SO-DIMM for laptops

This 8 GB module uses 260-pin DDR4 SO-DIMM form factor and runs at 3200 MT/s (PC4 25600) with CL22 timings at 1.20 V. It targets laptop owners who need a straightforward capacity increase for everyday multitasking and office workloads.

Fits standard DDR4 laptop slots

The stick installs in any 260-pin DDR4 SO-DIMM socket without adapters or cables. Its unbuffered, non-ECC design leaves the memory controller free for normal consumer operation and avoids the extra register logic found in server modules.

Sustained operation at rated speed

CL22 latency and 1.20 V voltage remain stable during extended sessions such as large spreadsheet recalculations or long compile jobs. The JEDEC-standard timings mean the module keeps its specified frequency without requiring manual tuning or higher voltages.

Questions about this item

Does the CL22 latency at 3200 MT/s become the bottleneck during long workloads?

The module runs at CL22 with 22-22-22 timings, so latency stays fixed at that level while the peak bandwidth is capped at the PC4 25600 rating.

How much heat and power should I expect from the 1.20 V unbuffered design running all day?

At 1.20 V the SO-DIMM draws minimal power and produces little heat; with no ECC or registered circuitry there is no extra thermal load.

My laptop only has 260-pin DDR4 slots — will this stick fit without an adapter?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the slot exactly; no adapter or extra hardware is needed.
