  • 260-pin SODIMM form factor fits ThinkPad T14 G3, T15 G2, T15g G1, T16 G1, X1 Extreme G3
  • Non-ECC unbuffered 2Rx8 design drops in as a direct replacement for Lenovo part numbers

Upgrade Memory for Select ThinkPad Models

This OWC SODIMM adds 16GB of DDR4 capacity to compatible Lenovo ThinkPad T14 G3, T15 G2, T15g G1, T16 G1 and X1 Extreme G3 laptops. It targets owners of those specific systems who need more memory for multitasking or larger workloads. The module is a direct replacement for several Lenovo part numbers including 01AG877 and 4X70Z90847.

Fits 260-Pin DDR4 Slots at 1.2V

The stick uses the standard 260-pin SO-DIMM form factor and runs at the JEDEC 1.2V voltage, so it drops into an empty slot without extra power or cooling. It is unbuffered, non-ECC and dual-rank 2Rx8, matching the electrical requirements of the listed ThinkPad platforms. Builders who need ECC, registered DIMMs or a different pin count cannot use this module.

Steady 3200MHz Operation at CL22

Rated for PC4-25600 at CL22, the memory maintains its 3200MHz data rate under sustained load because it follows JEDEC standard timings and voltage. Every module is tested in-house to verify long-term stability at the rated speed. Users seeking lower latency or higher frequencies than the JEDEC baseline will not find them here.

Questions about this item

Does the CL22 latency limit throughput during sustained workloads?

The module runs at DDR4 3200 with CL22 timing; that latency is the primary limit on sustained bandwidth.

How much heat or power does the 1.2 V unbuffered SODIMM generate when running all day?

At 1.2 V with no heat spreader the module draws minimal power and stays cool during continuous operation.

Which ThinkPad models must I already own for this 260-pin DDR4 SODIMM to work?

Compatible systems are ThinkPad T14 G3, T15 G2, T15g G1, T16 G1 and X1 Extreme G3.
