  • 1333 MHz DDR3 modules match dm1z series specification
  • CL9 9-9-9 timings deliver responsive data access
  • 5 V unbuffered SODIMMs install without voltage changes
  • 204-pin form factor fits both dm1z memory slots

Targeted Notebook Upgrade

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules rated at 1333 MHz with CL9 timing. They are built specifically for the HP/Compaq Pavilion dm1z series and run at the standard 1.5 V. The unbuffered, non-ECC design matches the notebook's original memory specification exactly.

Replaces Factory 4 GB Configurations

Many dm1z units shipped with a single 4 GB stick or two 2 GB sticks. Adding this 2 x 4 GB kit fills both slots and doubles the capacity to the platform maximum of 8 GB. The jump is worthwhile when the system slows under multitasking or when the integrated graphics shares system memory.

Straightforward Slot Installation

The 204-pin modules insert into the two SODIMM sockets accessible under the bottom panel. No heat spreaders are fitted, so clearance is not an issue. The most common mistake is seating only one side of the stick; press firmly until both retention clips click.

Questions about this item

Will the 204-pin DDR3 SODIMM modules fit the two memory slots in my HP Pavilion dm1z notebook?

Yes, the kit contains two 204-pin DDR3 SODIMMs designed for the two sockets in the dm1z series, providing the full 8 GB maximum the platform supports.

What is the correct way to seat each 1.5 V module so the 204 pins make full contact?

Insert the module at about a 30-degree angle until the gold edge disappears, then press down firmly until both side clips click; the common mistake is stopping at the angle without the final downward press.

When should I expect to replace these CL9 1333 MHz sticks?

DDR3 SODIMMs have no moving parts and typically last the life of the notebook; replacement is only needed if a module fails or you migrate to a system requiring a newer memory generation.
