8GB DDR5 4800 SODIMM for Dell G15

This OWC module is an 8GB DDR5 4800 CL40 262-pin SODIMM built for specific Dell G15 laptops. It runs at 1.1V with a 1Rx16 unbuffered non-ECC layout. The part number is 4S8D51R608GB and it replaces Dell part numbers AB949333 and SNPMVK8PC/8G.

Suits G15 5520 5521 5525 5530 owners

Buyers with a Dell G15 5520 5521 5525 or 5530 can install this as a direct upgrade. Systems that need ECC registered memory or a different pin count cannot use this module. Laptops outside the listed G15 models should verify compatibility before purchase.

JEDEC DDR5 4800 CL40 1.1V specification

The decisive spec is the DDR5 4800 PC5-38400 CL40 1.1V JEDEC rating. Your laptop must accept this exact speed voltage and timing combination. If the platform requires a different DDR5 data rate or lower latency the module will not operate as intended.

Questions about this item

Should I choose this 8GB DDR5 module or look for a 16GB version?

This module provides 8GB in a single 1Rx16 SODIMM. If your Dell G15 has two slots, adding a second identical module later gives 16GB dual-channel performance.

What does the 4800MHz CL40 rating mean once the module is installed?

The module runs at the JEDEC-standard DDR5 4800 speed with CL40 latency at 1.1V, delivering the baseline performance Dell specified for the G15 5520, 5521, 5525 and 5530.

Does the 262-pin DDR5 interface limit the speed compared to desktop DDR5?

The 262-pin SODIMM form factor carries the same DDR5 4800 signal; the laptop's memory controller caps the data rate at 4800 MT/s, matching this module's rating.
