8GB DDR4 SODIMM for laptops and NAS

This 8GB DDR4 2400 CL17 module fits 260-pin laptop, all-in-one and NAS slots. It runs at 1.2 V without ECC or buffering, matching JEDEC PC4-19200 specifications. The stick is designed as a direct replacement for NCR part numbers 2246-K601, 497-0507659 and 497-0526317.

Upgrade from 4GB or slower DDR4

Systems shipping with 4GB or with 2133 MHz DDR4 gain noticeable headroom for multitasking and larger files. The module is backward compatible with 2133 MHz buses, so it drops in without a BIOS change. Buyers who need more than 8 GB per slot or who require ECC registered memory must look elsewhere.

Tool-free slot insertion

Most laptops and mini desktops expose the SODIMM bay behind a single hatch; the module seats with a firm push until the side clips click. Common issues are forcing the keyed edge the wrong way or leaving the stick partially unseated, which causes a no-post condition. A quick visual check of the notch alignment prevents both problems.

Questions about this item

Will the 260-pin DDR4 SO-DIMM fit my laptop's memory slot?

Yes, the module uses the standard 260-pin DDR4 SO-DIMM form factor required by laptops, all-in-one systems and NAS units that accept DDR4 2400 memory.

What is the correct way to seat the module so it does not appear loose?

Line up the notch on the gold edge with the key in the slot, insert the module at an angle, then press down evenly until the side retention clips snap into the notches on both sides of the PCB.

Does this 8 GB stick require any firmware updates or battery replacements over time?

No, it is an unbuffered non-ECC DRAM module with no onboard firmware or battery; it only needs occasional dust removal from the gold contacts if the system is opened for other service.
