OWC 4GB DDR4 2133 SODIMM

This OWC module is a 4 GB DDR4 laptop memory upgrade rated at 2133 MT/s with CL15 latency. It uses the standard 260-pin SO-DIMM form factor and runs at 1.2 V. The part is unbuffered, non-ECC and has no heat spreader. It is designed as a direct replacement for NCR part numbers 4970509803 and 7607K134.

Suits DDR4 SO-DIMM slots only

The stick fits laptops, all-in-one systems, mini desktops, micro servers and NAS units that take DDR4 SO-DIMM memory. It will not work in systems that require registered or ECC modules, nor in platforms limited to lower-density chips. Buyers needing more than 4 GB per slot should look elsewhere.

Speed decides compatibility

The module operates at DDR4 2133 (PC4-17000) with a CAS latency of 15. If the target system requires a different data rate or tighter timings, this part will not be the correct match.

商品問答

Does my laptop need a 260-pin DDR4 SODIMM slot to use this 4GB module?

Yes, the module fits a standard 260-pin DDR4 SO-DIMM socket found in laptops, notebooks, mini desktops, micro servers, NAS systems and POS terminals.

Will this CL15 2133MHz stick run with my existing DDR4 2133 CL15 memory?

It uses the same DDR4 2133 PC4-17000 CL15 1.2V specification, so it will operate alongside identical modules at the rated speed and latency.

How can I confirm the 4GB module is recognised at 2133MHz after installation?

Check the BIOS or a system-information tool; it should report 4GB capacity, DDR4 technology, 2133MHz speed and CL15 timings.
