Computer Memory Solutions 4GB DDR3 1600MHz CL11 SODIMM memory upgrade

SKU CH-28ZZ-NZQQT

4GB DDR3 SODIMM module running at 1600MHz with CL11 timing for Lenovo ThinkPad T440p notebooks

  • Capacity4GB
  • Type204-Pin DDR3 SO-DIMM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Timing11-11-11
  • Voltage1.5V
  • 4GB capacity adds responsive multitasking headroom
  • DDR3 1600MHz speed matches ThinkPad T440p spec
  • CL11 timing keeps latency low for everyday workloads
  • 204-pin SODIMM form factor fits the notebook slots directly
  • 35V DDR3L operation reduces power draw without extra config

Purpose-built DDR3 SODIMM for ThinkPad T440p

This 4 GB module is engineered specifically for the Lenovo ThinkPad T440p 20ANxxx and 20AWxxx notebooks. It installs directly into the 204-pin DDR3 SO-DIMM slot without configuration. The unbuffered, non-ECC design matches the platform's native memory architecture. Buyers needing ECC error correction or registered buffering for server workloads should look elsewhere.

4 GB single stick at 1600 MHz CL11

The module runs at DDR3-12800 with 11-11-11 timings and operates at 1.5 V standard voltage. A single stick provides 4 GB of capacity; the system supports two sockets for a maximum of 16 GB total. Adding a second identical module enables dual-channel throughput. Users whose workloads already exceed 4 GB will not gain headroom from this single-stick upgrade alone.

Replaces factory DDR3 or DDR3L modules

This stick supersedes the original 4 GB or smaller DDR3/DDR3L SO-DIMMs shipped with the T440p. The jump is worthwhile when the current configuration leaves only one socket populated or when a failed module needs replacement. It does not increase the platform's two-socket, 16 GB ceiling, so systems already at that limit require a different platform.

Questions about this item

Will this 204-pin DDR3 module work alongside the original memory already installed in my ThinkPad T440p?

Yes, it is an unbuffered non-ECC SODIMM rated at 1600 MHz CL11, matching the factory specification for the T440p's two slots supporting up to 16 GB total.

How can I verify the stick is running at the correct 1600 MHz speed and CL11 timings after installation?

Open Task Manager's Performance tab or run CPU-Z; both will show the module operating at 1600 MHz with 11-11-11 timings at 1.35 V.

Does the package include only the single 4 GB SODIMM or are any tools or extra parts supplied?

The box contains one 4 GB DDR3L SODIMM and nothing else; no screwdriver, anti-static strap or additional modules are included.
