OWC 8GB DDR4 3200MHz SODIMM Upgrade

This 8GB DDR4 SODIMM module runs at 3200MHz with CL22 latency and 1.2V operation. It is built specifically for Lenovo Legion 7 and C7 series laptops including the 7-15IMH05, 7-16ACHG6, 7-16ITHG6, C7-15IMH05 and S7-15ACH6 models. The unbuffered, non-ECC design uses a 260-pin form factor.

Sustained load stability with JEDEC compliance

Every module is tested in-house to meet JEDEC standard specifications for reliable performance during extended workloads. The 1Rx8 rank configuration and standard voltage maintain consistent throughput without thermal throttling concerns. ROHS compliance ensures component longevity under continuous operation.

DDR4 SODIMM interface practical limits

The 260-pin DDR4 interface caps bandwidth at the PC4-25600 rating inherent to the 3200MHz specification. CL22 latency defines the minimum access delay for this speed grade. Builders needing higher capacity or lower latency must verify motherboard support for faster DDR4 variants beyond this module's fixed parameters.

Questions about this item

How much power does the 1.2V DDR4 module draw when the laptop runs all day?

The module operates at the standard 1.2V DDR4 voltage, keeping power draw low during continuous use.

What must the laptop already have for this 260-pin SODIMM to install and work?

A free DDR4 SODIMM slot and a memory controller that supports 3200 MHz CL22 operation.

Will this 8GB stick run stably alongside the original Lenovo memory in my Legion 7?

Yes — it matches the JEDEC 3200 MHz CL22 spec used by the factory modules, so mixed‑rank operation is stable.
