4 GB DDR3-1600 DIMM for Lenovo H30-05

This 240-pin unbuffered module adds 4 GB of system memory to a Lenovo H Series Desktop H30-05 90Bjxxx. It runs at 1600 MHz with a CL11 timing of 11-11-11 at 1.5 V. The single-rank 1Rx8 design uses major-brand chips without a heat spreader.

Sustained operation at 1600 MHz CL11

The module maintains its rated 1600 MHz speed and 11-11-11 timings under continuous workloads because it operates at the standard 1.5 V DDR3 voltage without overclocking headroom. Non-ECC unbuffered architecture keeps latency consistent during extended sessions. No thermal throttling occurs since the design lacks a heat spreader and relies on case airflow.

Verify two-slot limit and 16 GB maximum

The H30-05 90Bjxxx board provides only two DIMM sockets and supports a maximum of 16 GB total. Installing this 4 GB stick occupies one slot, leaving one free for a second module. Buyers needing more than 16 GB or four slots should consider a different platform.
