8 GB DDR4-2133 SO-DIMM

This Samsung M471A1K43BB0-CPB module provides 8 GB of DDR4 laptop memory running at 2133 MT/s with CL15 latency. It uses a 260-pin SO-DIMM form factor and operates at 1.20 V without ECC or registered buffers. The stick is supplied in OEM packaging.

Suits laptops with a free DDR4 SO-DIMM slot

Buyers upgrading a compatible notebook can add this single rank module to increase system memory. Systems that require ECC error correction or registered DIMMs cannot use this part. Machines limited to a different DDR generation or pin layout are also incompatible.

2133 MT/s data rate and CL15 timing

The module transfers data at 2133 MT/s (PC4-17000) with a CAS latency of 15 cycles and a cycle time of 0.93 ns. This speed and latency combination determines whether the memory matches the platform's supported specifications.

Questions about this item

Will the 260-pin SO-DIMM fit my laptop's DDR4 slot?

Yes, the module uses the standard 260-pin DDR4 SO-DIMM form factor used by most laptops supporting DDR4 memory.

Which way round does the notch go when inserting the stick?

Align the off-centre notch on the gold edge connector with the key in the slot; press down firmly until the side clips click into place.

Does the CL15 timing or 1.2 V voltage require any future adjustment?

No, the module runs at its rated 2133 MT/s CL15 at 1.2 V automatically; no maintenance or timing changes are needed during its service life.
