Compatible DDR3L upgrade for Sony Vaio VPCEE models

This 8 GB kit contains two 4 GB SODIMM modules built to the DDR3L 1600 standard. It targets owners of the Sony Vaio VPCEE32FD, VPCEE33EL, VPCEE33FX and VPCEE34FX who need to reach the platform maximum of 8 GB. The modules are unbuffered, non-ECC and use major-brand chipsets.

DDR3L 1600 speed and voltage ceiling

The memory runs at 1600 MHz with CL11 timings at 1.35 V. The supported platform also accepts DDR3-1066/PC3-8500, so the kit will down-clock if the system requires the lower speed. Total capacity cannot exceed 8 GB across the two available slots.

Two-slot installation with matched pair

Both slots must be populated to reach the 8 GB limit, so the paired sticks are installed together. The 204-pin SODIMM form factor fits the notebook slots directly. Mismatched capacities or mixing DDR3L with 1.5 V DDR3 can prevent the system from posting.

Questions about this item

Should I buy the 8GB kit or a single 4GB module for my Sony Vaio VPCEE33FX?

The VPCEE33FX supports a maximum of 8GB across two slots, so the 2 x 4GB kit fills both slots and reaches the system limit.

What does the PC3L-12800 1600MHz rating deliver in everyday use on this laptop?

It runs at DDR3L 1600 with CL11 timing at 1.35V, giving the full bandwidth the chipset allows for snappy multitasking and faster application loads.

Will the 204-pin DDR3L SODIMM work in my Vaio VPCEE32FD which specifies DDR3-1066?

Yes, the modules are backward compatible; they will operate at the board's native 1066MHz while maintaining 1.35V low-voltage operation.
