OWC 4GB DDR3 1600 CL11 1Rx8 204-pin 1.5V Non-ECC SODIMM memory upgrade

SKU CH-9T64-VNYQC

4GB DDR3 1600 SODIMM module upgrades compatible Lenovo ThinkPad laptops

  • Capacity4GB
  • Type204-Pin DDR3 Non-ECC SODIMM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.5V
  • ECCNo
  • 4GB capacity lets you run more apps simultaneously
  • DDR3 1600 speed with CL11 latency delivers responsive system performance
  • 204-pin SODIMM fits directly into compatible Lenovo ThinkPad laptops
  • 5V operation matches original memory voltage for stable compatibility
  • JEDEC and RoHS compliant module ensures warranty-safe upgrade

Targeted 4 GB DDR3 SODIMM for select ThinkPads

This 4 GB DDR3 1600 CL11 SODIMM fits Lenovo ThinkPad T530i, W530, X230, X230i, X240 and X240s models that accept 204-pin unbuffered non-ECC modules. It is aimed at owners of those systems who need a single-slot capacity increase without changing voltage or form factor.

Replaces slower or smaller DDR3 modules

The upgrade is worth it when the existing memory runs below 1600 MT/s or totals less than the platform maximum and the workload involves multitasking with several applications open. It will not help systems that already run matched 1600 MT/s pairs at the full supported capacity or that require registered or ECC memory.

Steady throughput under sustained multitasking loads

JEDEC-standard 1.5 V operation keeps power draw consistent during long sessions with multiple browser tabs, office suites or virtual machines. The single-rank 1Rx8 organisation avoids the timing penalties that can appear with dual-rank modules under continuous memory pressure, so responsiveness remains stable over hours of use.

Questions sur cet article

Does the 204-pin SODIMM fit the memory slot in a ThinkPad X230?

Yes, the module uses the standard 204-pin DDR3 SODIMM form factor required by the X230 and the other listed ThinkPad models.

What is the correct way to seat the module so the laptop recognises the full 4 GB?

Insert the SODIMM at an angle until the gold contacts disappear, then press down firmly until both side clips click into the notches on the module.

Will the memory need any firmware updates or periodic replacement after installation?

No firmware updates are required; the JEDEC-standard DDR3 module is designed to last the lifetime of the system under normal use.
