4GB DDR4 2666MHz SODIMM for HP Laptops

This 4GB DDR4 2666MHz CL19 module is built as a direct replacement for HP part numbers 937356-800, L10598-850 and L33259-001. It targets owners of compatible HP laptops, notebooks and all-in-one systems who need to restore or expand memory capacity with a verified match.

260-Pin Unbuffered Design at 1.2V

The stick uses a standard 260-pin SO-DIMM edge connector and runs at the DDR4 default voltage of 1.20V. It is unbuffered and non-ECC, so it drops into ordinary consumer laptop slots without requiring server-grade chipset support. No heat spreader is fitted, keeping the profile low for tight chassis clearances.

Steps Up from 2GB or Slower DDR4

Replacing a 2GB module or a slower DDR4 SO-DIMM with this 4GB PC4-21300 unit adds headroom for everyday multitasking and reduces swap-file activity. The upgrade is worthwhile when the system board accepts 2666MHz CL19 memory and the user wants a tested, lifetime-warranted module rather than an unverified alternative.

Questions about this item

What speed does the DDR4 2666MHz PC4-21300 interface actually run at in a laptop?

The module is rated for 2666 MT/s. The memory controller in the laptop will set the final speed, which can be lower if the system only supports a slower DDR4 rate.

Will this 260-pin SO-DIMM fit the memory slot in my HP laptop?

It uses the standard 260-pin DDR4 SO-DIMM form factor. The stick is physically compatible with any laptop slot that accepts DDR4 SO-DIMMs, including the HP part numbers 937356-800, L10598-850 and L33259-001.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the key in the slot, insert at a slight angle, then press down firmly until both side clips click into the notches. The step often missed is pressing hard enough to engage both clips fully.
