Lenovo ThinkCentre Edge 72 DDR3 Upgrade

This 4 GB DDR3 module is built for the Lenovo ThinkCentre Edge 72 Small Desktop. It runs at 1600 MHz with CL11 timing and 1.5 V unbuffered operation. The single 240-pin DIMM uses a 2Rx8 rank layout without a heat spreader.

Buyers needing more than one stick or ECC support

This kit contains only one 4 GB stick, so systems requiring a matched pair or a total capacity above 4 GB will need additional modules. The non-ECC design also makes it unsuitable for platforms that demand error-correcting memory.

240-pin DDR3 1600 CL11 specification

The module follows the PC3-12800 standard with 11-11-11 timings and 2Rx8 organisation. Only motherboards that accept 240-pin DDR3 at this speed and latency will recognise the stick correctly.

Questions about this item

Will the 240-pin DDR3 stick need any maintenance or replacement during its service life?

The module has no moving parts and no heat spreader, so no routine maintenance is required; it is covered by a limited lifetime warranty from Computer Memory Solutions.

What limit appears first when the memory runs continuously at 1600 MHz?

The system maximum of 16 GB across the two slots is reached before any speed or voltage ceiling, so adding a second 4 GB stick fills the capacity limit.

How much heat or power does the 1.5 V unbuffered DIMM produce during all-day operation?

At 1.5 V and standard DDR3 power levels the stick runs cool without a spreader, and the desktop's normal airflow handles the thermal load.
