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.

Questions about this item

Does the 1.5 V DDR3 1600 MHz module run hot or noisy under continuous use?

The stick has no heat spreader and no moving parts, so it adds no fan noise and minimal heat to the Lenovo H30-05 chassis.

What must the Lenovo H30-05 already have for this 240-pin DIMM to work?

The desktop needs a free DDR3 DIMM slot and a motherboard that accepts 1.5 V unbuffered non-ECC memory.

Will this single-rank CL11 stick work alongside the original memory in the H30-05?

It is designed for the H30-05 90Bjxxx platform, which supports up to 16 GB across two sockets.
