8GB DDR4 2400MHz SODIMM for ThinkPad L490 L590 T590

This 8GB DDR4 SO-DIMM module runs at 2400MHz with CL17 timing and 1.2V operation. It is built for Lenovo ThinkPad L490, L590 and T590 laptops that accept 260-pin unbuffered non-ECC memory. The single stick installs directly into an available SODIMM slot.

Upgrade from 4GB or 8GB factory configurations

Many of these ThinkPad models ship with 4GB or 8GB soldered or slotted memory. Adding this 8GB module raises total capacity toward the platform maximum of 48GB or 64GB depending on the specific chassis. The jump is worthwhile when multitasking, virtual machines or large datasets exceed the current physical memory.

Verify slot count and maximum supported capacity

These laptops offer one or two SODIMM sockets and a ceiling of 48GB or 64GB. Confirm how many slots your unit provides and whether the existing module occupies one. All installed memory will run at the slowest module speed, so matching 2400MHz CL17 timing preserves performance. A 64-bit operating system is required to address more than 4GB.

Questions about this item

What 260-pin SODIMM slot does this module fit in the ThinkPad L490 L590 T590?

It fits the standard DDR4 SO-DIMM socket inside the ThinkPad L490 L590 or T590; the laptops have one or two slots supporting up to 64 GB or 48 GB total.

How do I seat the 260-pin stick so the side clips engage?

Align the notch on the module with the key in the slot, insert at an angle until the gold fingers are fully hidden, then press down evenly until both metal clips snap into the side notches.

When will this 8 GB CL17 1.20 V module need replacement?

The stick carries a limited lifetime warranty from Computer Memory Solutions; it only needs replacing if a manufacturing defect appears or if you later exceed the 48 GB or 64 GB system maximum.
