Dell Latitude E5420 Max RAM Support

Every site I have looked at and the Dell specs specify 8 GB total as the maximum system RAM. I usually go to Crucial for the ultimate authority and they specify 8 GB total as well.

Welcome to the Dell Community  @Zeromix 

Most documentation says 8GB max.

What CPU do you have installed???

If needed I can pull one from my warehouse in the morning and test it for you???

Let me know about the CPU and if you want me to test 16GB and a W10 install???

Best regards,

U2

Thank you.

I´ve installed an I5-2430M CPU.

And it would be pretty helpful, if you could test that with 16 GB of RAM on an Windows 10 OS.

No problem @Zeromix 

I'm trying to make a W10 image for every model I have in the warehouse.

If I have not completed an E5420 image already then I will start one in the morning.

If I already have an image archived I will still try a fresh W10 install.

But first I will install 16GB of memory and boot to BIOS.

If that tests OK then I will start a fresh W10 install.

NOTE:

Your CPU is capable of 16GB.

@Zeromix 

First.

The unit I pulled from my warehouse is an E5420 i5-2520m  BIOS ver. A05

I installed your i5-2430m and upgraded the BIOS to the latest ver. A14

Then installed 16GB DDR3L-12800s 11-13-F3 memory.

Booted to BIOS with no problem.

I just started to install W10 Pro 64bit

Let you know how things go after it installs.

So it does work without any problems.

Thank you so much for investigate this, that helps me alot!

Your very welcome @Zeromix

Hello, So I read through this chat and I am having a very similar problem. I am looking to buy a dell latitude E5420 0r E5620. It is from discount computer depot and they allow you to customize it before they sell it to you. I am going to buy that computer with an i7 processor and everywhere I look it says 8GB of ddr3 RAM is the max I can put in. I am just running into the problem of will it fit? looking at the pictures of 4GB ddr3 RAM and 8 GB ddr3 ram the 8GB looks much longer. Did you fit the 8GB RAM into the laptop and manage to close it? 

Welcome to the Dell Community  @juswonderin 

Make sure the memory you purchase is for a laptop.

Desktop memory is to big and will not fit in a laptop.

Best regards,

U2

got it! I appreciate the info. @U2CAMEB4ME 

I have another question @U2CAMEB4ME  so I am going to put 16gb of RAM into a Dell latitude E5420 with an i7 processor and 1 tb drive calls for ddr3 1066 RM but I want something much faster If I put in ddr3 2133 RAM will it wait a lot faster. I have read that no matter how many MHz the RAM can output the motherboard will only operate at it's max MHz and buying ram that fast is a waste of money. Is this true ? If so what is or how do I don't the max MHz RAM my laptop will use? Any suggestions for increasing speed and GHz in this laptop are welcome.

when i typed dmidecode command with fedora 32:

$ dmidecode --type memory|head -7

it says, you have maximum 16 gb ram capacity.

8 GB ram ddr3 1600mhz  in each module, or 16gb ram ddr3 1600mhz in only one module, please?
