ThinkPad E15 G3 memory upgrade

This 8 GB DDR4 SODIMM is built specifically for the Lenovo ThinkPad E15 G3 and meets JEDEC PC4-25600 specifications. It installs as a direct replacement for the original Lenovo part numbers listed by the manufacturer.

Suitable for single-slot capacity increases

The module suits owners who want to add 8 GB of memory to a free slot or replace an existing stick in the E15 G3. It is not for buyers who need ECC error correction, registered buffering or a heat spreader.

Runs at DDR4 3200 CL22 1.2 V

The memory operates at 3200 MT/s with CAS latency 22 at the standard 1.2 V. This speed and voltage combination determines whether the laptop will boot and run stably with the upgrade.

Questions about this item

Will this 260-pin DDR4 SODIMM fit the memory slot in my ThinkPad E15 G3?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor that matches the ThinkPad E15 G3 memory slot exactly.

What is the correct way to seat this SODIMM, and what step do people often miss?

Insert the module at roughly a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click into the notches — the second click is the step most often missed.

Will I ever need to replace this 8GB DDR4 3200 CL22 module, and when?

The module itself has no wear-out mechanism; replacement is only needed if you want more capacity or if a rare defect appears, which is covered by the limited lifetime warranty.
