What this module is and who it fits

This is a single 8 GB DDR3L SODIMM running at 1066 MHz with a CAS latency of CL7. It uses the 204-pin form factor and operates at 1.35 V, making it suitable for laptops, notebooks and all-in-one systems that accept low-voltage DDR3 memory. The module is unbuffered and non-ECC, matching the requirements of most consumer mobile platforms.

What the listed compatibility replaces

The module is specified as a direct equivalent for Hynix part numbers HMT41GS6AFR8A-G7, HMT41GS6BFR8A-G7 and HMT41GS6MFR8A-G7. Choosing this kit means you can swap out one of those original sticks without changing any other component. The voltage, pin count and speed ratings align so the system recognises the memory automatically.

Installation notes and common pitfalls

Installation follows the standard SODIMM procedure: power off, open the memory door, align the notch with the slot key, insert at an angle and press down until the clips lock. The most frequent issue is a mismatch between DDR3L and standard 1.5 V DDR3 — systems that only support the higher voltage will not post with this 1.35 V stick. Verify the laptop’s supported memory specification before purchase.

Questions about this item

Will the 204-pin DDR3L SODIMM need any periodic maintenance or replacement after installation?

No, the module has no moving parts and requires no maintenance; it is designed to remain in service for the life of the laptop.

What limit appears first when the 8 GB DDR3L 1066 MHz module runs at full load for extended periods?

The memory controller’s 1066 MHz data-rate ceiling is reached before thermal or voltage limits become a factor.

How much heat and power does the 1.35 V DDR3L SODIMM produce during all-day operation?

At 1.35 V the module draws minimal power and generates only modest warmth, well within normal laptop cooling capacity.
