8GB DDR3L SODIMM for Lenovo Y and Z Series

This single 8GB DDR3L 1600 module upgrades compatible Lenovo Y50-70, Y70-70 Touch, Z50-70, Z50-75 and Z70-80 laptops. It uses a 204-pin SODIMM form factor and operates at 1.35V with CL11 latency. The memory is unbuffered, non-ECC and organised as 2Rx8. It is built to JEDEC standards and intended for users who want a straightforward capacity increase.

Fits a single SODIMM slot in the listed Lenovo

Installation requires an available 204-pin DDR3L slot in one of the supported notebooks. The module draws 1.35V, matching the DDR3L voltage specification for those platforms. Because it is unbuffered and non-ECC, it works with the standard consumer memory controller in these systems. No heat spreader is fitted, so clearance inside tight chassis is not affected.

8GB capacity handles everyday multitasking

The 8GB density lets you keep more applications and documents open simultaneously without swapping. Speed is rated at DDR3L 1600 (PC3L-12800) with CL11 timing, providing the bandwidth the supported chipsets expect. It will not suit builds that require ECC error correction, registered modules, higher capacities per slot or a different DDR generation.

Questions about this item

Will the CL11 latency become a bottleneck during long rendering sessions?

CL11 is the rated CAS latency for this DDR3L 1600 module and remains constant under sustained load.

Does the 1.35 V DDR3L module run hotter or louder than standard 1.5 V DDR3 in a laptop chassis?

The 1.35 V DDR3L specification reduces power draw compared to 1.5 V DDR3, producing less heat and no audible noise.

My Lenovo Y50-70 has one empty SODIMM slot — will this 204-pin 2Rx8 stick work without a matching module?

Yes, the unbuffered non-ECC SODIMM installs as a single 8 GB upgrade in any compatible Lenovo model listed.
