OWC 4GB DDR4 2400MHz CL17 SODIMM laptop RAM

SKU CH-T74D-NDJCP

Adds 4 GB of DDR4-2400 CL17 memory to compatible laptops and small-form-factor systems

  • Total capacity4 GB
  • Rated speedDDR4 2400 (PC4 19200)
  • CAS latencyCL17
  • ECC supportNon-ECC
  • Buffer typeUnbuffered
  • Product type260-Pin DDR4 SO-DIMM

Capacity 4GB

  • Boost responsiveness with 2400 MHz DDR4 speed
  • Reduce power draw at 1.2 V operating voltage
  • Fit standard slots using 260-pin SO-DIMM form factor
  • Run reliably with JEDEC-compliant CL17 timing
  • Upgrade laptops, mini desktops, NAS or POS systems

Upgrade Module for Laptops and Mini Systems

This 4GB DDR4 SO-DIMM targets laptops, notebooks, mini desktops, micro servers, NAS units and POS terminals that accept 260-pin memory. It provides a straightforward capacity increase for systems running below their maximum supported memory. Builders needing ECC protection or registered modules should look elsewhere.

DDR4 2400 Standard Limits

The module operates at 2400MHz with CL17 latency and 1.2V voltage under the PC4-19200 specification. It is backwards compatible with 2133MHz slots, though the system will run at the lower speed. JEDEC compliance ensures broad interoperability, but the memory cannot exceed the 2400MHz data rate defined by the standard.

Single 4GB Unbuffered Non-ECC Stick

The kit consists of one 1Rx8 unbuffered Non-ECC module, delivering exactly 4GB of capacity. This density suits a single-slot upgrade or a matched pair installation where the platform supports it. Systems requiring higher density per slot, ECC error correction or registered buffering will not accept this part.

Questions about this item

Should I pick the 4 GB module or add a second one for dual-channel?

This listing is a single 4 GB stick. If your laptop has two slots and you want dual-channel bandwidth, buy two identical modules.

What does the 2400 MHz rating actually deliver in my notebook?

The module runs at 2400 MHz with CL17 timing, giving a peak transfer rate of PC4-19200. Real-world speed depends on your CPU's memory controller and whether the system operates in single or dual-channel mode.

Will the 260-pin DDR4 SO-DIMM fit and run at 2133 MHz if my system only supports that speed?

Yes. The 260-pin DDR4 SO-DIMM is backward compatible and will automatically down-clock to 2133 MHz on platforms that do not support 2400 MHz.
