8GB DDR4 2400 SODIMM for laptops

This 8 GB DDR4 2400 module fits 260-pin laptop slots and runs at 1.20 V with CL17 timing. It is built as an unbuffered non-ECC stick using major-brand chips and is validated as a direct replacement for Crucial CT8G4SFD824A. The single-module design suits owners who need one compatible upgrade without guessing capacity limits.

Steady throughput at rated speed

The module operates continuously at its rated DDR4 2400 frequency under sustained workloads rather than relying on short bursts. Standard 1.20 V power keeps thermals predictable during long sessions, and the unbuffered topology avoids added latency that registered designs introduce. CL17 timing stays consistent as the system maintains heavy multitasking or background tasks over time.

260-pin SO-DIMM form factor

The 260-pin edge connector aligns with the DDR4 SO-DIMM socket found in compatible notebooks and all-in-one systems. Unbuffered construction means the module seats directly without extra height from register components, easing installation in tight chassis. Major-brand chips on the PCB support reliable contact over repeated thermal cycles in daily use.

Questions about this item

Does the 1.20V DDR4 module run cooler than higher-voltage memory during all-day use?

DDR4 standard voltage is 1.20V, so this stick operates at the baseline power level for the technology and does not draw extra current that would increase heat.

My laptop only has 260-pin SO-DIMM slots — is that the only requirement for this upgrade?

Yes, the module uses the 260-pin SO-DIMM form factor used by DDR4 laptops; you also need a free slot and a system that accepts DDR4 2400 non-ECC unbuffered memory.

Can I keep my existing DDR4 2400 CL17 module and add this one for dual-channel operation?

Matching speed, voltage and CAS latency allows dual-channel mode; this module shares the same 2400 MT/s rate, 1.20V supply and CL17 timing.
