Targeted upgrade

This 4 GB DDR3 DIMM is built for the Lenovo H Series Desktop H50-50. It delivers a straightforward memory increase for everyday computing tasks. The single-module design fits one of the system's two available slots.

Build and connection

The unbuffered 240-pin stick uses major-brand chips and runs at 1.5 V with CL11 timing. No heat spreader is fitted, keeping the profile low for tight chassis layouts. Installation follows standard DIMM alignment on the desktop motherboard.

DDR3 platform limits

The DDR3 1600 interface caps bandwidth at PC3 12800, so data throughput is fixed by the memory standard. The board supports a maximum of 16 GB across its two sockets. Buyers needing more capacity or a newer memory generation must choose a different platform.
