Compatible upgrade for Dell Latitude 5420

This 8GB kit contains two 4GB DDR3 SO-DIMM modules built for the Dell Latitude 5420 notebook. Each stick uses a 204-pin interface and runs at 1600MHz with CL11 timing at 1.5V. The unbuffered, non-ECC design fits the factory memory slots without modification.

Sustained throughput with dual-channel pairs

The modules must be installed in pairs to enable dual-channel mode on supported systems. With a CAS latency of 11 and 11-11-11 timing, the kit delivers steady bandwidth during extended workloads rather than only peak bursts. Major-brand chipsets and 1Rx8 organisation help maintain stability over long sessions.

Replaces factory memory when 8GB is the limit

This kit matches the maximum 8GB capacity supported by the platform and fills both available sockets. If a single 4GB module is currently installed, adding the pair avoids the 3.5GB recognition limit seen with mismatched configurations. A 64-bit operating system is required to address the full capacity.

Questions about this item

Does the 1.5V DDR3 1600MHz kit run warm or draw extra power during all-day use?

Standard 1.5V DDR3 modules operate at JEDEC voltage, so heat and power draw stay within normal notebook limits for this speed.

Must the Dell Latitude 5420 already have free 204-pin SODIMM slots to install this 2x4GB kit?

Yes, the 5420 has two SODIMM sockets; both must be empty or you must remove existing modules to install the matched pair.

Will this CL11 1Rx8 memory work if I keep an older 4GB stick in the second slot?

Mixing ranks or timings can prevent dual-channel mode; the 5420 requires matched pairs, so install both 4GB sticks together.
