HP HDX X18 DDR3 Upgrade

This 4 GB DDR3 SODIMM is built specifically for the HP HDX X18 series. It delivers a direct memory increase for owners of those notebooks who need more capacity for everyday multitasking. The module matches the original DDR3 1066 specification exactly.

204-Pin SODIMM Build

The stick uses a standard 204-pin SODIMM edge connector that slots into the laptop's memory socket without adapters. It has no heat spreader, keeping the profile low for tight chassis clearance. Unbuffered, non-ECC operation suits the consumer platform.

DDR3 1066 Platform Limit

The PC3-8500 CL7 rating sets the maximum data rate for this DDR3 generation. Systems that require faster DDR3 speeds or a different voltage will not benefit from this module. Buyers needing higher bandwidth or larger single-module capacities must look beyond the DDR3 1066 standard.
