Target system and kit layout

This 8 GB kit contains two 4 GB DDR3L SODIMM modules built for the Lenovo ThinkCentre M72z all-in-one desktop. The parts run at 1600 MHz with CL11 timing at 1.35 V and are unbuffered non-ECC. They are designed for the 204-pin slots used in models 3538, 3548, 3554 and 3558.

Ideal fit and limits

The kit suits owners of those ThinkCentre M72z units who need the full 8 GB maximum supported by the platform and want a matched pair for dual-channel operation. Buyers whose systems accept only a single module, or who require ECC or registered memory, should look elsewhere because this product is unbuffered non-ECC and the platform demands paired installation.

Deciding specification

The critical detail is the 204-pin DDR3L SODIMM form factor combined with 1.35 V operation at 1600 MHz CL11. If the target machine uses a different pin count, voltage or DDR generation the modules will not fit or function correctly.

Questions about this item

How much power do these DDR3L 1600MHz CL11 modules draw when the system runs all day?

They operate at 1.35V, which is the standard low-voltage level for DDR3L SODIMMs and keeps power draw and heat lower than 1.5V DDR3 equivalents.

What must my Lenovo ThinkCentre M72z already have so this 2x4GB kit installs and runs in dual-channel mode?

Two free 204-pin SODIMM slots; the board supports up to 8GB total and modules must be installed in matched pairs for dual-channel operation.

Will these 1Rx8 single-rank sticks work alongside the original 4GB modules that came in my M72z 3538 or 3558?

Yes, they are validated for the M72z series (3538, 3548, 3554, 3558); mixing ranks is supported, though the system will run at the slowest installed speed and total capacity stays within the 8GB limit.
