Does Dell Latitude E6420 Supports Over 8GB of RAM in Practice?

Jump to solution

Good day to owners of Dell Latitude E6420! Did any of you try in practice to install over 8GB of RAM in your laptop to see if it is capable of working with over its maximum size which is 8GB? I ask because in my previous HP laptop manual stated that it supports up to 2GB of RAM though there were owners (of which I am also) who installed over laptop's maximum officially stated capacity with no problems. Thats' why I thought it won't hurt to ask here.

Thanks for the reply @Syndormess

The 'official Dell' Specs stated that the amount of Ram is limited to 8GB.

However Intel's Sandy Bridge is capable of handling 32GB: (From Intel's website)

Max Memory Size (dependent on memory type)
32 GB
Memory Types
DDR3-1066/1333/1600

Source: http://ark.intel.com/products/50067/Intel-Core-i7-2720QM-Processor-6M-Cache-up-to-3_30-GHz

It made sense when most people were using 32bit Windows to specify the RAM at 4GB as that was all it could handle. The 4GB upper limit did not need to change.

Now that most users have gravitated  towards 64bit operating systems, which has a theoretical max of 192GB, this becomes an issue that needs constant updating,

Perhaps the Dell lab coat guys could provide us with definitive guidance as to the exact specification of 2 x 8GB sims or 2 x 16GB sims ((DDR3-1066/1333/1600) ) that the E6420 and the E series can handle, and what changes to software are needed, eg. BIOS etc.

I'm running 16GB successfully:

E6420, BIOS A17

Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz

16342 MBytes

PC3-12800J (800 MHz)

Corsair CMSX8GX3M1A1600C10

BIOS sees them running at 1600Mhz, which was a surprise.  memtest ran successfully, and so far it's working very well.

@SpeedStep Did you try yourself putting more than 8GB or you just quoting technical specifications?

Has anyone tried this or can Dell indicate whether more than 8GB of RAM can be used on Latitude E6420?

Check this forum post because he succeeded making 16GB work with his E6420 but keep in mind that he might have different configuration of components in his laptop.
