Product Identity

This 8GB DDR3 1600 SODIMM is built for Lenovo ThinkPad Edge E430 E430c E530 E530c E535 and S430 laptops. It targets owners of those specific models who want a single-module memory increase without opening the case for multiple sticks.

Compliance and Support

JEDEC and RoHS compliance make the upgrade warranty-safe for the listed ThinkPad Edge systems. The limited lifetime warranty and advanced replacement programme cover the module itself, not the laptop or any other component.

DDR3 Platform Limits

DDR3 1600 CL11 at 1.5V is the native speed ceiling for this memory generation; the module will not run faster than the platform allows. Systems that require ECC registered DIMMs or a different pin count cannot use this SODIMM.

Highlights

  • 8GB capacity lets you run more apps simultaneously
  • DDR3 1600 speed matches factory specs for responsive multitasking
  • CL11 latency keeps data moving without extra delay
  • 204-pin SODIMM fits ThinkPad Edge E430, E530, E535 and S430 slots
  • 5V non-ECC unbuffered design installs easily with no configuration needed

Questions about this item

Will the 2Rx8 rank layout on this SODIMM require any future firmware updates or matching modules?

The module uses a 2Rx8 organisation at DDR3 1600 CL11. No firmware updates are needed for the memory itself; matching capacity and speed is recommended when adding a second stick.

What is the first limit reached when this 1.5 V DDR3 1600 module runs continuously at full load?

The JEDEC-standard 1.5 V supply and CL11 timing set the thermal and stability ceiling; sustained writes will hit the DDR3 1600 bandwidth limit before voltage or latency become bottlenecks.

How much heat and fan noise does this non-ECC SODIMM add during all-day operation in a ThinkPad Edge?

Without a heat spreader the 8 GB stick relies on the laptop's existing airflow; power draw stays at the standard 1.5 V DDR3 level, so fan behaviour is unchanged from the factory configuration.
