System-specific DDR3 SODIMM for Lenovo Ideapad Z575

This 4 GB module is built for the Lenovo Ideapad Z575 series notebook. It uses 204-pin DDR3 SO-DIMM form factor and runs at 1333 MHz with CAS latency 7. The stick is unbuffered, non-ECC and operates at 1.5 V, making it a direct drop-in upgrade for compatible models.

Installation notes and common issues

The module installs in a standard 204-pin SODIMM slot and requires no tools beyond a small screwdriver. MODULES MUST BE ORDERED AND INSTALLED IN PAIRS for dual-channel mode if supported. If a single 4 GB stick is fitted, the recognised memory may be reduced to 3.5 GB or less depending on system configuration and memory allocation.

Compatibility checks before ordering

Verify your notebook is a Lenovo Ideapad Z575 series model before purchase. The system maximum memory is 8 GB across two sockets, so confirm the number of free slots and the installed operating system. Maximum configurations require a 64-bit operating system. P/N: CM5126410600SODRH.

Questions about this item

How can I verify the memory is running at 1333 MHz with CL7 timings after installation?

Enter the system BIOS or use a tool such as CPU-Z to confirm the module reports DDR3-1333 speed and 7-7-7 latency at 1.5 V.

What is included in the package and is anything else required for the upgrade?

The box contains one 4 GB 204-pin DDR3 SODIMM stick; no extra parts are needed, but adding a second identical module enables dual-channel mode.

Should I choose the 1333 MHz CL7 version or the 1600 MHz alternative for my Z575?

The Z575 series supports DDR3-1333; the 1600 MHz rating is a manufacturer highlight but the system will operate the memory at 1333 MHz.
