Sony Vaio VPCEE DDR3 1600MHz SO-DIMM kit

This 8 GB kit contains two 4 GB DDR3 1600 MHz SO-DIMM modules built for Sony Vaio VPCEE series notebooks. The sticks run at 1.5 V with CL11 11-11-11 timings and use unbuffered non-ECC chips on a 204-pin PCB. Computer Memory Solutions validates compatibility with the VPCEE2M1E, VPCEE2S1E, VPCEE31FX and VPCEE32FX models.

Who should buy and who should not

Owners of the listed Vaio VPCEE laptops who need the maximum 8 GB the platform allows will reach that ceiling with this kit. Buyers whose machines require ECC or registered memory cannot use these unbuffered non-ECC modules. Systems limited to DDR3 1066 speeds will still run the memory but at the lower frequency.

Deciding specification — 204-pin DDR3 1600 SO-DIMM

The modules are 204-pin DDR3 SO-DIMMs rated at 1600 MHz (PC3-12800) with a 1.5 V operating voltage. If the target notebook accepts DDR3 SO-DIMMs at this speed and voltage the kit will install and operate at the rated CL11 timings. Any other DDR generation or pin count will not fit the slot.

Questions about this item

Will these 1.5 V CL11 modules run in my Vaio VPCEE that originally shipped with 1.35 V DDR3-1066 sticks?

The kit is rated at 1.5 V and CL11 at 1600 MHz; the laptop will clock them down to the board's supported 1066 MHz, but the higher voltage may exceed the original 1.35 V spec.

How can I confirm both 4 GB sticks are recognised at 1600 MHz after installation?

Open Task Manager or CPU-Z and verify the memory tab shows 8 GB total running at 800 MHz (DDR3-1600 effective) with 11-11-11 timings.

Does the package include only the two SODIMM sticks or any tools or adapters?

The box contains exactly two 204-pin DDR3 SODIMM modules; no screwdriver, bracket or adapter is supplied.
