OWC 64GB (2x32GB) DDR5 5600 CL46 SODIMM memory upgrade

Lenovo ThinkPad DDR5 SODIMM upgrade

This 64GB kit contains two 32GB DDR5 5600 CL46 modules built for Lenovo ThinkPad E14 Gen 6, E16 Gen 2, P1 Gen 6 and P16v Gen 1 laptops. It targets professionals who need more memory for multitasking, large datasets or virtual machines. The JEDEC-standard DDR5 SODIMMs run at 1.1V without ECC or heat spreaders. Buyers with other laptop models or desktop systems cannot use these modules.

Dual-channel kit for soldered-slot systems

Each stick uses the 262-pin SODIMM form factor and 2Rx8 organisation to populate both memory channels in compatible ThinkPads. The unbuffered design drops into the user-accessible slots without tools or firmware changes. Because the kit is matched at the factory, it avoids timing mismatches that can occur with mixed modules. Systems that have soldered memory only or a single slot will not accept the full 64GB.

Low-voltage DDR5 thermals and power

Operating at the standard 1.1V, the modules draw minimal power and generate little heat during typical workloads. With no heat spreader or active cooling, they rely on the laptop’s existing airflow, keeping acoustic levels unchanged. The non-ECC unbuffered layout adds no latency overhead for everyday applications. Workloads that push sustained maximum bandwidth will see higher temperatures but remain within JEDEC limits.
