SK hynix 4GB DDR3L 1600 CL11 1.35V 204-Pin SoDIMM laptop RAM

4GB DDR3L SoDIMM for laptop upgrades

This 4 GB DDR3L module runs at 1600 MHz with CL11 latency and a 1.35 V operating voltage. It uses the standard 204-pin SO-DIMM form factor for laptop memory slots. The unbuffered, non-ECC design suits mainstream notebook platforms. Buyers who need ECC error correction or registered buffering should look elsewhere.

Sustained load behaviour at CL11 1.35V

The low-voltage DDR3L specification keeps power draw modest during extended workloads. CL11 timing delivers consistent access latency for everyday multitasking and office applications. Dual-rank organisation helps maintain throughput when the memory controller issues back-to-back requests. Systems limited to 1.5 V DDR3 slots may not boot with this 1.35 V module.

Compatibility checks before ordering

Verify that your laptop accepts 204-pin DDR3L SO-DIMMs and supports 1.35 V operation. Confirm the motherboard can address a 4 GB unbuffered non-ECC module in the target slot. Check whether the BIOS requires a specific SPD profile for DDR3L 1600 (PC3L 12800). Ensure no physical obstruction prevents the module from seating fully in the socket.
