System-specific DDR3 kit for ThinkCentre M79

This 8 GB kit contains two 4 GB unbuffered non-ECC DIMMs built to run at 1600 MHz with CL11 timing at 1.5 V. It is validated for the Lenovo ThinkCentre M79 in both small-form-factor and tower chassis.

Straightforward dual-channel installation

Modules must be ordered and installed in matched pairs to enable dual-channel mode. The system provides four 240-pin slots with a maximum of 4 GB per slot, so this pair fills half the sockets. If 4 GB modules are already present, the recognised total may be limited to 3.5 GB or less depending on configuration.

32 GB platform ceiling with paired-population rule

The ThinkCentre M79 platform supports up to 32 GB of DDR3 memory across its four slots, but each slot is capped at 4 GB and modules must be populated in pairs. A 64-bit operating system is required to address the full 32 GB.

Questions about this item

How can I confirm the kit is running at 1600MHz with CL11 timing after installation?

Open Task Manager or CPU-Z and check the memory tab; it should show DDR3 1600 (PC3 12800) with 11-11-11 timings at 1.5V.

What comes in the box and is anything else required for the ThinkCentre M79?

The package includes two 4GB 240-pin DDR3 DIMMs; no extra parts are needed — just install them in matched pairs for dual-channel mode.

Which capacity kit should I choose if the M79 has four slots and supports 32GB maximum?

This 8GB (2x4GB) kit fills two slots; add a second identical kit later to reach the 32GB limit with all four slots populated.
