System-specific DDR3 kit

This 8 GB kit contains two 4 GB DDR3 1066 MHz SO-DIMM modules built for select Fujitsu Lifebook models including the LH520, LH530, LH531, LH700 and NH570. Each stick uses a 204-pin unbuffered, non-ECC design rated at CL7 7-7-7 timing and 1.5 V. The kit targets owners of those notebooks who need the maximum factory-supported memory capacity.

Sustained workload behaviour

Rated at PC3-8500 with 2Rx8 organisation and major-brand chips, the modules maintain their specified 1066 MHz speed and CL7 latency during extended sessions without a heat spreader. The 1.5 V operating voltage matches the original platform specification, so thermal output stays within the laptop’s cooling envelope even when both slots are populated.

Installation notes

Installation requires opening the memory compartment and inserting both 204-pin sticks into the two available sockets; the kit provides the full 8 GB maximum the platform recognises. A 64-bit operating system is needed to address the complete capacity, otherwise the system may report only 3.5 GB or less. Buyers with a single 4 GB module already installed cannot add just one stick from this pair without exceeding the two-socket limit.

Questions about this item

How much power does this 1.5V DDR3 kit draw when the Lifebook runs all day?

Each module operates at 1.5V, the standard voltage for DDR3 SODIMMs, so power draw stays within normal laptop limits during continuous use.

Which free slots must my Lifebook already have for this 204-pin kit to install?

The upgrade needs two empty 204-pin SODIMM slots; the listed models provide two sockets for a maximum of 8GB.

Will this CL7 1066MHz memory work if I keep the original 4GB stick in my Lifebook?

The system supports 8GB total across two sockets; adding this 2×4GB kit fills both slots, so the original stick must be removed.
