System-Specific DDR3 Kit

This 16 GB kit contains four 4 GB SODIMM modules built to DDR3 1333 (PC3 10600) with CL7 timing. It is designed for Dell Precision mobile workstation motherboards that accept 204-pin unbuffered memory. Buyers needing ECC or registered DIMMs should look elsewhere.

Sustained-Load Behaviour

Operating at 1.5 V with a 2Rx8 organisation, the modules maintain their rated 7-7-7 latency during extended workloads. The lack of a heat spreader means airflow in the chassis determines thermal headroom, so cramped enclosures may see throttling sooner than open layouts.

Upgrade Context

The kit fills all four sockets for a maximum 16 GB configuration on supported dual-core models and matches the 16 GB dual-core limit noted by the supplier. Systems already running 16 GB of slower DDR3 will not gain capacity from this kit, only potential latency improvement.

Questions about this item

Does the 1.5V DDR3 kit run hot or draw extra power during all-day workloads?

Standard 1.5V DDR3 modules operate within normal thermal limits for mobile workstations; no additional cooling is required beyond the laptop's built-in airflow.

Must the Dell Precision M6400 already have a quad-core CPU for this 16GB kit to be recognised?

The M6400 supports 16GB with dual-core processors and 32GB with quad-core processors; either CPU configuration will recognise the full 16GB kit.

Can I mix these CL7 1333MHz SODIMMs with slower CL9 sticks already in the M6400?

The system will down-clock all modules to the slowest installed speed and latency, so CL9 sticks will force the kit to run at CL9 timings.
