Compatible 8GB DDR3L SODIMM upgrade

This 8GB DDR3L 1600MHz SODIMM module is built for HP 15 Series notebooks 15-ac128la, 15-ac136la and 15-ac157cl. It delivers 12800 speed at 1.35V with CL11 timing. The unbuffered, non-ECC design uses major brand chips in a 2Rx8 configuration.

Check your notebook slot and voltage

Verify the laptop accepts a single 204-pin DDR3L SODIMM running at 1.35V. The system must support 1600MHz operation and have a free slot for this 8GB stick. Confirm the model number matches 15-ac128la, 15-ac136la or 15-ac157cl before ordering.

Steady throughput under load

Sustained workloads run at the rated 1600MHz with 11-11-11 timings without throttling. The 1.35V low-voltage design keeps power draw stable during extended sessions. Unbuffered operation ensures consistent latency for everyday multitasking and memory-intensive applications.
