Compatible Lenovo ThinkPad Upgrade

This 8GB DDR4 SODIMM is built for the Lenovo ThinkPad 13 2nd Gen, A475, E470 and E475. It delivers a direct memory increase for those specific notebooks without requiring configuration changes. The module uses a 260-pin layout and operates at 1.2V.

Suits single-slot expansion; not for ECC systems

The stick fits owners wanting to add 8GB to a supported ThinkPad with a free slot. It does not serve buyers who need error-correcting code memory, registered modules or capacities beyond the 32GB platform maximum. Systems requiring ECC or buffered DIMMs must look elsewhere.

2400 MHz DDR4 speed rating

The module runs at DDR4 2400 (PC4 19200) with CL17 timing. This speed decides whether the part matches the platform's memory controller specification. Verify the laptop's supported rate before purchase.

Questions about this item

Does the 1.2 V DDR4 2400 module run cool and quiet during continuous use?

The 1.2 V DDR4 2400 SO-DIMM operates at standard laptop voltage with no heat spreader, so it produces minimal heat and makes no noise in a ThinkPad 13 2nd Gen, A475, E470 or E475.

What must my laptop already have to accept this 260-pin SO-DIMM?

Your ThinkPad needs a free DDR4 SO-DIMM slot supporting 2400 MHz unbuffered non-ECC memory; the compatible models listed each provide two such sockets.

Will this CL17 2Rx8 stick work alongside the original memory in my E470?

The module is rated CL17 at 2400 MHz and uses a 2Rx8 organisation; the system will run both sticks at the lowest common speed and latency.
