8 GB DDR4 2400 SODIMM for Dell Inspiron 17

This 8 GB DDR4 2400 MHz SODIMM is built for Dell Inspiron 17 models 3781, 3785, 5770 and 5775. It uses a 260-pin unbuffered non-ECC layout running at 1.2 V with CL17 timing. The single module installs directly into an available slot to raise system memory.

Who this suits and who should look elsewhere

This module suits owners of the listed Inspiron 17 notebooks who need a straightforward memory increase up to the platform maximum of 32 GB. Buyers whose laptop requires ECC or registered memory cannot use this kit. Systems limited to lower DDR4 speeds or different pin counts are not compatible.

The specification that decides fit

The 260-pin DDR4 2400 non-ECC SODIMM form factor is the single specification that decides fit. Only notebooks accepting this exact module type at 1.2 V with CL17 timing will recognise and run the memory correctly.

Questions about this item

Does this 260-pin DDR4 SODIMM fit the two memory slots in my Dell Inspiron 17 5770?

Yes, the module matches the 260-pin DDR4 SODIMM format used by the Inspiron 17 5770 and the system supports up to 32 GB across its two slots.

Will the CL17 timing on this 2400 MHz stick force my existing CL15 memory to run slower?

The memory controller will synchronize both modules at the slower CL17 timing, so your original CL15 stick will operate at CL17 speeds.

How can I confirm the new 8 GB module is recognised at 2400 MHz after installation?

Open Task Manager, go to the Performance tab, select Memory and verify the speed reads 2400 MHz and the total capacity shows the expected increase.
