4 GB DDR4 2666 SO-DIMM

This SK hynix module provides 4 GB of DDR4 memory in a 260-pin SO-DIMM form factor. It runs at 2666 MT/s with a CAS latency of CL19 and operates at the standard 1.20 V. The unbuffered, non-ECC design is intended for laptop memory slots.

Suits owners of DDR4 laptops needing a single 4 GB

This module fits notebooks that accept 260-pin DDR4 SO-DIMMs at 2666 MT/s. Systems requiring ECC, registered memory, higher capacities per slot, or a different pin count cannot use this part.

260-pin DDR4 SO-DIMM interface

The 260-pin SO-DIMM connector is the sole physical and electrical interface that determines compatibility. Verify the laptop manual specifies DDR4 SO-DIMM slots before purchase.

商品問答

Will the CL19 latency ever require adjustment or replacement?

The CL19 timing is fixed in the module's SPD and does not change; no maintenance or replacement is needed for latency.

What limit appears first during sustained heavy workloads?

The 4 GB capacity fills before speed or latency become bottlenecks in typical sustained use.

How much heat and power does the 1.20 V module produce running all day?

At 1.20 V the SO-DIMM draws minimal power and generates low heat; it has no fan and runs silently.
