OWC 4GB DDR4 2400 CL17 260-pin SODIMM laptop RAM

SKU CH-4D3V-F5XD8

A 4 GB DDR4 2400 CL17 SODIMM module for upgrading laptops, all-in-ones and NAS systems

  • Total capacity4 GB
  • Rated speedDDR4 2400 (PC4 19200)
  • CAS latencyCL17
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Recommended forLaptops, All-in-One Systems, and NAS Systems
  • 4 GB capacity expands multitasking headroom for everyday workloads
  • DDR4 2400 speed with CL17 timing delivers responsive system performance
  • 2 V low-voltage operation reduces power draw and heat
  • 260-pin SO-DIMM form factor fits laptops, all-in-ones and NAS units
  • JEDEC and RoHS compliant for warranty-safe upgrades

Direct replacement for NCR systems

This 4GB DDR4 SODIMM matches NCR part numbers 1925-K004, 497-0531031 and 497-0531312. It runs at 2400MHz with CL17 latency and 1.2V voltage. The module is designed for laptops, all-in-one PCs and NAS devices needing a straightforward memory upgrade.

JEDEC standard unbuffered module

The 260-pin SO-DIMM fits standard DDR4 slots without a heat spreader, keeping height low for tight chassis. Non-ECC, unbuffered operation suits consumer and small-business platforms. Backward compatibility with 2133MHz systems allows use in older DDR4 boards without configuration changes.

Upgrade from 2133MHz or lower capacity

Installing this module replaces slower 2133MHz sticks or adds capacity where a single slot is free. The jump is worthwhile when multitasking slows due to memory pressure or when a system ships with only 4GB total. Buyers needing ECC error correction or registered buffering should look elsewhere.

Questions about this item

Does the DDR4 2400 PC4-19200 interface limit real-world speed to 2400 MT/s?

Yes, the module runs at 2400 MT/s with CL17 latency; it is also backward compatible with 2133 MT/s systems.

Will the 260-pin SODIMM fit a standard laptop memory slot?

The 260-pin DDR4 SO-DIMM form factor matches the standard slot used in laptops, all-in-one PCs, mini desktops, micro servers, NAS and POS systems.

What is the correct way to seat the module so it locks in place?

Align the notch on the gold edge with the key in the slot, press firmly until the side clips click, then verify the module sits flat with no gold contacts visible.
