Targeted 8GB DDR4 SO-DIMM upgrade

This 8GB module is built for Dell Inspiron 15 (7577) Gaming, Inspiron 17 (7778) and Inspiron 24 (5475) systems. It uses 260-pin DDR4 SO-DIMM form factor with CL17 timing at 1.2V. The single stick suits owners who need a straightforward capacity increase without ECC or registered buffers.

Fits two-slot DDR4 laptops and all-in-ones

The unbuffered, non-ECC design drops into the two SO-DIMM sockets found in the listed Inspiron models. No heat spreader keeps the profile low for tight chassis clearance. Installing one module leaves the second socket free for a matching stick to enable dual-channel operation.

8GB capacity with 16GB system ceiling

Each kit delivers 8GB at DDR4 2400 (PC4 19200). The compatible platforms support a maximum of 16GB across two slots, so a second identical module completes the full upgrade path. Beyond 16GB the memory controller cannot address additional capacity.

Questions about this item

What is the CAS latency of this CM1024642400SO module and how does it affect sustained throughput?

The module runs at CL17 with 17-17-17 timings at 2400 MHz, so the 17-cycle latency is the first bottleneck you hit during long, bandwidth-heavy workloads.

Does the stick generate noticeable heat or fan noise when the laptop runs all day?

It has no heat spreader and operates at the standard 1.2 V, so thermal output stays low and does not trigger extra fan activity in the compatible Dell models.

Which Dell laptops must I already own for this 260-pin SO-DIMM to work?

It is validated for Dell Inspiron 15 (7577) Gaming, Inspiron 17 (7778) and Inspiron 24 (5475) systems that accept DDR4 SO-DIMM memory.
