OWC 4GB DDR3L 1600 SODIMM

This 4GB DDR3L SODIMM runs at 1600 MT/s with CL11 latency and 1.35V operation. It uses a 204-pin unbuffered non-ECC layout built to JEDEC and RoHS standards. The single-rank 1Rx8 module targets compatible Lenovo ThinkPad notebooks.

Compatible ThinkPad models

The upgrade fits ThinkPad T440p, T440s, T450, T450s, T460, T540p and T550 systems. Buyers with other laptop families or desktop platforms should look elsewhere. Systems requiring ECC, registered DIMMs or a different voltage are not supported.

Speed and voltage spec

DDR3L 1600 (PC3L-12800) at 1.35V is the decisive specification for this part. Confirm your notebook accepts this exact speed and voltage before ordering. Mismatched memory will not function correctly.

Points forts

  • Boosts system responsiveness with 4GB DDR3L 1600 CL11 module
  • Runs cooler at 1.35V low-voltage DDR3L standard
  • Fits ThinkPad T440p, T440s, T450, T450s, T460, T540p, T550

Questions sur cet article

Does my ThinkPad T450s need a free 204-pin SODIMM slot for this 4GB DDR3L 1600 module?

Yes, the module fits one 204-pin DDR3L SODIMM slot, so an empty slot is required for installation.

Can I keep my existing 1.35V DDR3L 1600 CL11 stick and add this 1Rx8 module alongside it?

The module matches the 1.35V DDR3L 1600 CL11 spec, so it will run at the same speed and timings as an identical stick.

How do I confirm the new 4GB module is recognised at 1600 MT/s after I install it?

Check the memory speed in Task Manager or BIOS; it should show 1600 MT/s for the added module.
