Dell Latitude E5420M memory kit

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built for the Dell Latitude E5420M notebook. Each stick uses a 204-pin interface and runs at 1066 MHz with CL7 timing. The unbuffered, non-ECC design matches the factory specification for this system.

Sustained workload behaviour

Operating at a standard 1.5 V, the modules maintain their rated 1066 MHz speed under continuous load without throttling. The CL7 7-7-7 timings stay consistent during extended sessions, so latency does not drift as the chips warm up. Major-brand components provide stable throughput for typical office and multitasking workloads.

Installation notes

The SO-DIMM form factor slides directly into the two memory sockets on the Latitude E5420M with no tools required. Because the kit is system-specific, the BIOS recognises the SPD data immediately and no manual configuration is needed. Buyers who need more than 8 GB or who own a different laptop model cannot use this kit.

Questions about this item

How much power does the 1.5 V DDR3 kit draw when the Latitude E5420M runs all day?

Each module operates at the standard DDR3 voltage of 1.5 V, so total power draw stays within the notebook's normal memory budget during continuous use.

What must the Dell Latitude E5420M already have for this 204-pin kit to work?

The notebook needs two free DDR3 SO-DIMM slots and a BIOS that recognises 4 GB unbuffered non-ECC modules at 1066 MHz.

Will these CL7 1066 MHz modules run stably with any original memory left in the Latitude E5420M?

The kit is validated for the Latitude E5420M; when mixed with factory memory the system will operate at the lowest common speed and timing.
