Lenovo ThinkPad W530 memory kit

This 32 GB kit contains four 8 GB DDR3L SODIMM modules rated at 1600 MHz with CL11 timing and 1.35 V operation. The 204-pin unbuffered non-ECC sticks are built with major-brand chipsets and carry a limited lifetime warranty from Computer Memory Solutions. They are validated for the ThinkPad W530 series including part numbers 2436, 2438, 2439, 2441 and 2447.

Suitable for W530 owners needing maximum capacity

The kit fills all four memory slots to reach the 32 GB ceiling documented for these notebooks, making it appropriate for users running memory-intensive workloads such as virtual machines or large datasets. Buyers whose W530 units have fewer than four accessible slots or who require ECC registered memory should look elsewhere, as this kit is unbuffered non-ECC and occupies the full complement of sockets.

DDR3L 1600 CL11 at 1.35 V

The decisive specification is the DDR3L 1600 speed grade with CL11 latency at 1.35 volts, which matches the voltage and timing window the W530 memory controller expects. Modules rated for higher voltage or different timing profiles will not operate correctly in this platform, so confirming this exact electrical profile is the single check that determines compatibility.

Questions about this item

My ThinkPad W530 has four SODIMM slots — do I need to populate all four for this 32GB kit to run correctly?

The kit contains four 8GB modules totalling 32GB. The W530 series supports a maximum of 32GB across four sockets, so filling every slot is required to reach that capacity.

Can I keep my existing 1.5V DDR3 SODIMMs installed alongside these 1.35V DDR3L modules?

These modules operate at 1.35V DDR3L. Mixing voltages is not recommended; the system will typically default to the higher voltage, which can prevent the DDR3L sticks from functioning reliably.

After installation, how can I verify the memory is running at DDR3-1600 CL11 as specified?

Open Task Manager or a tool such as CPU-Z and confirm the speed reads 1600 MHz with timings of 11-11-11. The BIOS memory information screen will also show 32GB total at DDR3-12800.
