8 GB DDR4-2133 laptop module

This SK hynix SODIMM delivers 8 GB of DDR4 memory at 2133 MHz with a CL15 latency and 1.2 V operation. The 260-pin unbuffered stick is a 2Rx8 rank device rated at PC4-17000. It is sold new and individually tested for immediate use in compatible notebooks.

Upgrade seekers vs full-kit buyers

The single module suits owners adding capacity to an empty slot or replacing one failed stick in a dual-channel laptop. Buyers wanting a factory-matched pair for guaranteed dual-channel performance or those needing ECC error correction should look at a different product.

2133 MHz DDR4 speed rating

The decisive specification is the DDR4-2133 (PC4-17000) speed grade; the memory controller must support this exact frequency for stable operation. Verify the laptop’s qualified-vendor list before purchase.

Questions about this item

Does my laptop need a 260-pin DDR4 SO-DIMM slot to use this module?

Yes, this is a 260-pin DDR4 SO-DIMM that fits laptops with a matching DDR4 slot.

Will this CL15 2133MHz stick run stably alongside my existing CL15 2133MHz RAM?

It should run stably if the other module is also DDR4 2133 CL15 1.2V unbuffered non-ECC; the system will operate both at the shared speed and timing.

How can I confirm the module is detected at 2133MHz after installation?

Check the memory speed in BIOS or a tool like CPU-Z; it should report 2133MHz (PC4-17000) with CL15 timings at 1.2V.
