OWC 4GB DDR3L 1600 UDIMM

This 4GB DDR3L module runs at 1600 MT/s with CL11 latency and 1.35V operation. It fits 240-pin desktop slots in compatible Lenovo ThinkCentre systems. The unbuffered, non-ECC design suits standard office and home PCs needing a straightforward capacity increase.

Upgrade from 2GB or 4GB factory configurations

Replacing a single 2GB stick or adding to an empty slot raises total memory without changing voltage or speed. The jump is worthwhile when the system currently stalls on everyday multitasking or when the original module limits the platform to single-channel bandwidth.

Handles typical office workloads and light media

Four gigabytes comfortably runs a modern browser with several tabs, office suites and background utilities. It runs out when large creative files, virtual machines or many simultaneous applications push committed memory beyond the physical limit, forcing heavy paging.

Questions about this item

Will the 240-pin DDR3L UDIMM fit in the ThinkCentre M83 Tiny chassis?

The module uses the standard 240-pin DDR3L UDIMM form factor required by the M83 Tiny, E73, M72e, M83, M92, M92p and M93 desktops.

What is the correct orientation step when seating this 1.35 V module in the DIMM slot?

Align the notch on the 240-pin edge connector with the key in the slot, press down evenly until both retention clips click, and verify the 1.35 V DDR3L module sits flush.

When should I consider replacing this CL11 1Rx8 kit?

Replace the 4 GB DDR3L 1600 module if memory diagnostics report errors, the system becomes unstable under load, or you upgrade to a platform that no longer supports DDR3L.
