Single 8GB DDR3 1600 SODIMM

This module delivers 8GB of DDR3 1600 memory in a 204-pin SODIMM form factor. It runs at 1.5V with CL11 latency and a 2Rx8 organisation. The kit is validated for Lenovo ThinkPad T530i, W530, X230, X230i, X240 and X240s systems.

Suits owners of those ThinkPads wanting

Buyers needing ECC or registered DIMMs cannot use this module. It is also unsuitable for any system that requires a different DDR generation or a 260-pin form factor. Builders looking for a matched pair or higher total capacity should look elsewhere.

DDR3 1600 CL11 1.5V 2Rx8 specification

The speed, voltage, latency and rank combination determines whether the module will be accepted by the ThinkPad memory controller. Confirm that the target laptop expects PC3-12800 CL11 1.5V 2Rx8 SODIMMs before ordering.

Questions about this item

How do I install the 204-pin SODIMM in my ThinkPad X230, and what step do people miss?

Power off, unplug, remove the battery, open the memory door, align the notch on the 204-pin DDR3 module with the slot key, press firmly until both side clips click, then reassemble; the step often missed is fully seating the module so both clips engage.

Will the 1.5V DDR3 module need any maintenance or replacement later?

No routine maintenance is required; the non-ECC unbuffered SODIMM has no moving parts or heat spreader, so it runs until a rare cell failure or a platform upgrade makes DDR3 obsolete.

What limit appears first when the CL11 1600MHz memory runs under sustained load?

The DDR3 1600 PC3-12800 CL11 timing and 1.5V voltage set the bandwidth and latency ceiling; thermal throttling is unlikely without a spreader, so the JEDEC-specified speed grade is the first hard limit.
