Dell Precision M6400 module

This is a new 4GB DDR3 SODIMM built to upgrade the Dell Precision M6400 mobile workstation. It runs at 1066MHz with CL7 latency and uses the standard 204-pin unbuffered non-ECC layout. The single module delivers a straightforward capacity increase for that specific platform.

Suitable for M6400 owners needing more memory

The part matches the factory voltage of 1.5V and the JEDEC PC3-8500 timing, so it installs without configuration changes. It is not for systems that require ECC or registered modules, nor for boards that only accept different pin counts or voltages.

204-pin DDR3 1066MHz CL7 SODIMM

The 204-pin DDR3 interface at 1066MHz with CL7 timing is the single specification that decides fit. If the target machine calls for this exact pin count, speed and latency, the module will work; otherwise it will not seat or post.

Questions about this item

Will this 204-pin DDR3 1066 SODIMM work in the second slot if I keep an existing PC3-8500 module in the first slot?

Yes — both modules run at 1066 MHz with CL7 timing and 1.5 V, so the system will operate them in dual-channel mode without down-clocking.

How can I verify the module is detected at the correct 1066 MHz speed after installing it in my Dell Precision M6400?

Open Task Manager’s Performance tab or run CPU-Z; the memory section should show 1066 MHz (PC3-8500) and CL7 latency for the new 4 GB SODIMM.

Does the 8S5D32R804GB package include only the single 4 GB SODIMM, or are tools and thermal pads also supplied?

The box contains only the 204-pin DDR3 SODIMM; no screwdriver, thermal pad or additional hardware is included.
