In this post I explain how to replace or upgrade memory (RAM) on a Dell Latitude D830 notebook.
Also, these instructions should work for a Dell Latitude D820 and maybe some other models. If it works for you, please mention the model in the comments.
You can check the amount of installed RAM in the BIOS setup menu. As you see, in my Dell I have 1024MB (or 1GB).
Dell Latitude D830 has two RAM slots. You should use PC2-5300 SODIMM which runs at 667MHz.
You can use same memory type for a Latitude D820 too.
Dell Latitude D820/D830 can take up to 4GB memory total. You can install up to 2GB module in each slot.
Now the tricky part.
One slot (DIMM B) can be easily accessed on the bottom of the laptop. Another one (DIMM A) located under the keyboard.
Yep, in order to access the first memory slot we’ll have to remove the keyboard.
Before you start, please turn off the computer, unplug the AC power adapter and remove the battery.
Lift up one side of the keyboard cover with a small flat head screwdriver.
Remove the cover.
Remove three screws securing the keyboard.
Lift up the keyboard from the top cover and move it towards the display panel.
Be careful, it’s attached to the motherboard via a flat ribbon cable.
The DIMM A is located just above the touch pad buttons.
In order to remove the existing memory module carefully spread latches on both sides of the slot.
The module will pop up at a 30 degree angle.
Pull the RAM by the edges.
Now you can install a new memory module into the slot DIMM A.
In this notebook RAM can run in dual-channel mode which doubles the amount of available bandwidth and improves the laptop performance.
In order to run dual-channel mode you must have two identical memory modules in slots A and B.
For example, if you have a 1GB module installed into the slot A, you have to install an identical 1GB module into the slot B. In this case it will run in dual-channel mode.
