Questions about this item

Will this 288‑pin DDR4 UDIMM fit the Dell Precision 3430 motherboard?

Yes, the module is built to the 288‑pin DDR4 UDIMM form factor that the Precision 3430, 3431 and 3630 use.

What is the correct way to seat the module so the CL19 timing is recognised?

Align the notch with the slot key, press down firmly until both retention clips click, then power on and confirm 2666 MHz in BIOS.

When should I expect to replace this 8 GB stick?

DDR4 memory has no scheduled replacement interval; it runs until a fault appears or you upgrade capacity.
