System-Specific DDR5 SODIMM for Dell G16

This OWC module delivers 16 GB of DDR5 memory at 4800 MT/s with CL40 latency and 1.1 V operation. The 262-pin unbuffered non-ECC SODIMM is validated for Dell G16 7620 and 7630 laptops. JEDEC compliance ensures a warranty-safe upgrade path.

Upgrade from factory DDR5 or add capacity

Replacing a lower-capacity DDR5 stick or filling an empty slot raises total system memory for heavier multitasking. The jump is worthwhile when the current configuration limits the number of open applications or large files you can handle simultaneously.

Suits owners of compatible G16 models needing more

Buyers with a Dell G16 7620 or 7630 who want a straightforward capacity increase will benefit. Those whose systems require ECC, registered modules, a different pin count, or a voltage other than 1.1 V should look elsewhere.
