System-Specific DDR3 Kit

This 4 GB kit contains two 2 GB DDR3-1600 DIMMs built for Lenovo ThinkCentre M78 Small and Tower desktops. The modules run at 1.5 V with CL11 timing and are unbuffered non-ECC parts. They are intended for owners of those specific Lenovo models who want a matched pair to fill two slots.

Verify Your M78 Configuration

Confirm that your ThinkCentre M78 is one of the listed part-number families such as 1562, 1565, 1766, 2111, 2113, 2114, 4865 or 5100. The board provides four 240-pin slots with a maximum capacity of 32 GB, so adding this kit will occupy half the available sockets. Ensure the system BIOS is up to date before installing new memory.

Matched Pair Simplifies Installation

The two sticks are packaged together as a tested kit, removing the guesswork of mixing modules with different timings or voltages. No heat spreaders are included, keeping the profile low for compact Small-form-factor chassis. The supplier backs the modules with a limited lifetime warranty when purchased directly from Computer Memory Solutions.

Questions about this item

What comes in the box and do I need anything else to install it?

The package contains two 2 GB DDR3 DIMM modules. No extra parts are required for installation in a compatible Lenovo ThinkCentre M78.

Should I pick the 1.5 V or 1.35 V version for my M78?

The modules are rated at 1.5 V and will also run at 1.35 V if the system requests it, so a single kit covers both voltages.

Will the CL11 1600 MHz speed actually run at that rate in my ThinkCentre M78?

The system supports DDR3-1600, so the memory will operate at 1600 MHz with CL11 timings when installed.
