8GB DDR3L SODIMM for ASUS Q551LN

This 8GB DDR3L SODIMM module runs at 1600MHz with CL11 timings and operates at 1.35V. It is a 204-pin unbuffered non-ECC stick built specifically for the ASUS Q551LN notebook. The single-rank 2Rx8 design uses major-brand chips to ensure reliable compatibility. Buyers needing more than 16GB total capacity or a second slot populated beyond the two available sockets should consider other options.

Low-voltage operation and thermal profile

The 1.35V DDR3L rating reduces power draw compared to standard 1.5V DDR3 modules. Without a heat spreader, the module relies on the notebook's internal airflow for cooling. Under normal office workloads the stick runs cool and silent, adding minimal thermal load to the compact Q551LN chassis. Systems requiring registered or ECC memory will not be supported by this unbuffered design.

Sustained workload behaviour

During extended multitasking or memory-intensive tasks the CL11 11-11-11 timings maintain consistent latency at the rated 1600MHz speed. The 2Rx8 organisation allows the memory controller to interleave accesses across ranks, helping sustain throughput. The module is validated for the Q551LN's maximum 16GB limit across its two sockets, so a pair of these sticks will fill the system without stability issues.

Questions about this item

How do I install the 204-pin SODIMM in the Q551LN and what step is often missed?

Power off, unplug and remove the battery; open the bottom memory door, insert the module at an angle until the gold contacts disappear, then press down until both side clips click — the missed step is forgetting to reseat the battery before the first boot.

What maintenance or replacement will the CM10246412800SODRL need later?

No scheduled maintenance is required; if a fault appears the module carries a lifetime exchange warranty from Computer Memory Solutions, otherwise it runs for the notebook's usable life.

What limit appears first under sustained load with this DDR3L 1600 CL11 kit?

The platform's two-slot, 16 GB maximum capacity is reached before the memory's own thermal or bandwidth ceiling becomes a bottleneck.
