8GB DDR4 2400 SODIMM Kit

This kit supplies 8 GB of DDR4-2400 memory in two 4 GB SODIMM modules. Each stick runs at 1.2 V with CL17 latency and a 2Rx8 rank layout. The 260-pin unbuffered, non-ECC design targets laptop and small-form-factor upgrades.

Who this fits and who it does not

Suitable for systems that accept DDR4 SODIMMs at 2400 MHz and benefit from matched-pair installation. Not for desktops needing DIMMs, builds requiring ECC or registered modules, or configurations limited to lower voltage or single-rank memory.

Deciding specification: DDR4-2400 SODIMM

The memory type and speed are the critical match points. Your platform must support DDR4 SODIMMs at 2400 MHz (PC4-19200) with 260-pin unbuffered, non-ECC modules. If the board or CPU only runs slower or faster speeds, or demands a different form factor, this kit will not work.

Questions about this item

How do I install the 260-pin DDR4 SODIMM modules and what step is often missed?

Align the notch on each 260-pin SODIMM with the slot key, insert at an angle, then press down firmly until both side clips click into place; the step often missed is not pushing far enough for the clips to engage fully.

What maintenance or replacement will this 2x4GB DDR4 2400MHz kit need later?

No routine maintenance is required; keep the contacts clean and ensure the system stays dust-free. Replacement is only needed if a module fails, which is covered by the manufacturer's limited lifetime warranty against defects.

What limit appears first under sustained use with these CL17 1.2V modules?

The primary limit is the DDR4 2400MHz speed ceiling; all installed memory will run at the slowest module's speed or the processor's maximum supported memory frequency, whichever is lower.
