Targeted Laptop Upgrade

This 8 GB DDR4 SO-DIMM is built for Dell Gaming G3 15 (3590), G5 15 (5590), G5 15 5579 and G7 15 (7590) notebooks. It suits owners who need a single module to add capacity or replace a failed stick in those specific models.

Single-Stick Expansion

The module adds 8 GB to systems that support up to 32 GB across two slots. The jump is worthwhile when the laptop currently runs with less memory or a slower CL19 2666 MHz stick and the user wants matched capacity without buying a pair.

Straightforward Slot Fit

Installation uses the standard 260-pin SO-DIMM socket; the unbuffered 1.2 V design requires no configuration in BIOS. The main risk is mixing speeds — all installed memory will run at the slowest module present.

商品問答

Will the 260-pin DDR4 SO-DIMM fit the memory slots in my Dell G3 15 3590 or G5 15 5590?

Yes, this module uses the standard 260-pin DDR4 SO-DIMM form factor required by those laptops and matches the DDR4 2666 speed they support.

What is the correct way to seat the module so the laptop recognises the full 8 GB?

Insert the stick at roughly a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click into the notches on the PCB.

When would the CL19 1.2 V unbuffered stick need to be replaced?

Only if a memory test reports errors or the system becomes unstable; otherwise the limited lifetime warranty from Computer Memory Solutions covers manufacturing defects for as long as you own it.
