16GB DDR4 SODIMM for ThinkPad P-series

This 16GB DDR4 3200MHz CL22 module upgrades compatible Lenovo ThinkPad P15 G2, P15s G1, P15s G2, P15v G1 and P15v G2 laptops. It runs at 1.2V as a 260-pin non-ECC unbuffered SODIMM. The part number is 3S2D42R816GB and it replaces several Lenovo OEM part numbers including 01AG877 and 4X70Z90847.

JEDEC compliant 260-pin build

The module meets JEDEC standard specifications and is RoHS compliant for a warranty-safe upgrade. It uses a standard 260-pin SODIMM form factor without a heat spreader, fitting directly into the laptop memory slot. OWC tests every module in-house to ensure reliability and compatibility with the listed systems.

Replaces factory 8GB or 16GB sticks

This kit replaces original Lenovo modules such as 5M30V06972, 5M30Z71707 and 4X71D09535. The jump is worth it when your workload needs more than the soldered or single-stock capacity allows, letting you open larger files and run more apps simultaneously. Buyers whose laptops already have two populated slots or who need ECC registered memory cannot use this module.

Questions about this item

What does DDR4 3200 PC4-25600 mean for real-world bandwidth?

The module runs at 3200 MT/s with a peak transfer rate of 25600 MB/s; actual throughput depends on the laptop's memory controller and whether you run single or dual channel.

What physical slot and keying does this 260-pin SODIMM need?

It fits a standard DDR4 260-pin SO-DIMM socket with the DDR4 key notch; the P15 G2, P15s G1/G2 and P15v G1/G2 all use this slot type.

What is the correct way to seat the module so it locks?

Align the notch, insert at roughly 30 degrees, press down firmly until both side clips click — the most common mistake is stopping before the clips engage.
