Dell Latitude D610 laptop has two memory slots available for upgrades. This laptop can take up to 2GB, so you can install up to 1GB memory module in each slot.
You should use PC2-4200 DDR2-533 SODIMM memory modules. Your laptop will work in dual channel mode (recommended) if you install two identical memory modules. In my case, I’m going to install two 1GB PC2-4200 modules.
One of the memory slots (Slot B) can be accessed through the door on the bottom of the laptop. The second slot (Slot A) is hidden under the keyboard, so we’ll have to remove the keyboard. If your laptop was configured with only one memory module, you’ll find it in slot A.
Before you do anything, do not forget to remove the battery.

Let’s remove the keyboard. Insert a flat head screwdriver between the keyboard bezel and laptop case and carefully lift up the bezel. Remove the bezel.

You’ll find two screws securing the keyboard. Remove both screws.

Now carefully lift up the keyboard. You’ll see the default memory module under the keyboard, right above the touch pad buttons. It’s possible to replace the memory module without disconnecting the keyboard.

I will disconnect the keyboard so I can make better pictures for you. Simply grab the blue tag attached to the keyboard connector and pull it up. Now you can remove the keyboard.

On the picture below you can see the default memory module installed into the slot A. In order to remove it, spread latches on both side with your fingers.

The memory module will pop up at a 30 degree angle.

Now you can pull the default memory module from the slot and replace it with a new one.
I’m installing a 1GB module into this slot.

Finally, install another 1GB module into the slot on the bottom. Turn on the laptop and you are ready to go!

Thank you. This made it so easy. My wife thanks you too. She has no patients for the old slow laptop, now she has a new friend in the fast easy laptop.

Worked like a charm. Excellent instructions.

This is a very common mistake. If you laptop recognize only one module after the upgrade, make sure the second module is seated correctly.

fatherdaddy,
If the laptop bus runs at 533MHz than you will not benefit from using a 667MHz memory module. This module will work fine but will slow down and run at 533MHz.
You can use a 667MHz module but it doesn’t mean that your laptop will run faster. It will be the same as using a 533MHz module.

For the Dell D610, what about using PC2-5300 667MHz? is that better, the same, or worse than using 533MHz?

Great guide – gave me the confidence to tackle the upgrade. It was as easy as described. Initially it only recognised 1GB but I found that the second module hadn’t been pushed firmly enough into its socket. I removed and replaced it and it then found 2GB on start up.
On restart you will get a ‘memory has changed’ message. Wait a few minutes and eventually you will have the option to press F1 to continue. I see that some people just get the ‘memory has changed’ message and nothing else. Maybe the module under the keyboard isn’t pushed home enough and this causes this error? Worth trying I guess.
PC is much quicker. 2 x 1GB modules cost me £27 from Crucial with next-day delivery and it was well worth it. I was thinking of buying a new laptop – don’t need to now

Thanks for the tutorial! I changed my ram out by myself and everything worked perfectly!!

Hey man… awesome tutoriall… one issue though, I have same problem as Emma, the computer says: Memory Changed and it stays there. no response from keyboard.
I used 1gB X 2 PC2-5300 memories.
The one it used to have it’s a 512mB PC2-4200
It’s ok to change from 4200 to 5300 or it will not work?

Can I upgrade RAM memory using a different bus speed?
Currently I have 256MB DDR2 533 MHz, can I install an additional 1GB 667 MHz or a 2GB 800 MHz ?
Will this work ?
Thanks.
