  • Total capacity4 GB
  • 4GB capacity adds responsive multitasking headroom

  • Low 1.35V voltage reduces power draw and heat
  • 204-pin SO-DIMM fits standard laptop memory slots

Capacity and speed

This SK hynix module provides 4GB of DDR3 laptop memory running at 1600 MHz with a CAS latency of 11. It uses the 204-pin SO-DIMM form factor and operates at a low 1.35 V. The stick is sold new and carries the manufacturer part number HMT451S6AFR8C-PB.

Upgrade fit and limits

The single 4GB capacity suits a basic capacity increase for an older DDR3 notebook that has a free slot. It does not serve users who need 8GB or more in a single module, nor those whose laptop requires a different pin count or voltage. Non-ECC design means it will not work in systems that demand error-correcting memory.

Questions about this item

Does the HMT451S6AFR8C-PB module ship with any brackets or installation tools, or is it just the bare SO-DIMM?

Only the 4GB DDR3 SO-DIMM is supplied; no brackets, screws or tools are included.

Should I choose the 1.35V CL11 version or look for a different voltage and latency for my laptop?

This stick runs at 1.35V with CL11 timing at 1600MHz; match those specs to your laptop's requirements.
