8 GB DDR3 kit for laptop upgrades

This Timetec kit supplies 8 GB of DDR3 memory as two 4 GB modules built with Hynix ICs. It targets owners of compatible notebooks who want to add capacity or replace existing sticks with a matched pair.

Replaces slower or smaller DDR3 SO-DIMMs

The jump is worthwhile when your system currently runs on less than 8 GB or uses modules rated below 1066 MHz and CL7. Swapping to this matched kit can raise the memory ceiling and tighten latency in one step.

Check DDR3 SO-DIMM slot count and voltage

Verify that your notebook accepts 204-pin unbuffered non-ECC DDR3 at 1.5 V and has two free slots or can replace the existing pair. The modules measure 30 mm by 67.6 mm, so confirm physical clearance before ordering.

Questions about this item

Will the 204-pin SO-DIMM fit my laptop's memory slot?

The kit uses standard 204-pin DDR3 SO-DIMM modules measuring 30 mm by 67.6 mm, which match the JEDEC form factor for laptop memory slots.

What is the correct way to seat the modules during installation?

Insert each module at an angle into the 204-pin slot, then press down evenly until the side retention clips click into place on both sides.

Do these dual-rank 2Rx8 modules require any firmware updates or periodic maintenance?

No firmware updates are needed; the modules are non-ECC unbuffered DDR3 running at 1.50 V and operate maintenance-free for the life of the laptop.
