This guide explains how to access both RAM sockets and replace memory in a Dell Latitude D630 laptop. This set of instructions is very similar to the memory upgrade tutorial I just posted for a Latitude D610 laptop.
How much memory can you install into a Dell Latitude D630?
According to the Dell specifications this laptop will take up to 8GB RAM total. You can install up to 4GB RAM into each socket. 4GB RAM modules are not available at the time of writing this post. At this time you can install maximum 2GB module into each socket. I was wrong, I found a 4GB RAM module made by Kingston (part number: KTT667D2/4G) but it’s only $395. LOL.
There are two sockets in this computer available for memory upgrades.
Socket B can be accessed through the hatch on the bottom.
Socket A is hidden under the keyboard. Yes, you’ll have to remove the keyboard in order to access this socket.
What memory type should you use?
You should use DDR2 667 (PC2 5300) SODIMM modules for notebook computers.
Can you install different size RAM modules into the laptop?
Yes, you can. For example, you can have a 1GB module in the socket A and install a 2GB module into the socket B. Your laptop will see 3GB total.
But if you want your memory to operate in dual-channel mode (better performance), you’ll have to install identical size and type memory modules into both sockets.

leet,
Haven’t tried it myself.
I provided a link to Dell™ Latitude™ D630/D630c User’s Guide and it says:
Maximum memory – 4 GB/8 GB capable.
It’s not very clear if both D630/D630C are 8GB capable or
D630 can handle 4GB max and
D630C is 8GB capable.
I didn’t have a chance to test it myself.

Are you sure that D630 is able to handle 8GB? I understand from the link you published in the post #2 that D630 can handle 4GB max and D630c can handle 8GB. How can I check whether I have D630 or D630c? Can someone confirm that D630 runs with 8GB RAM?

joel,
You can remove memory modules one by one and run the laptop with only one (either one) memory module installed.
Also, you can download Memtest86+ and test each memory module individually.

I am having intermittent problems (blue screen) that seems to be caused by memory. how can i tell which of the two memory modules (i have two 1-gig modules) is the one causing the problem?

Hi Tech,
Thanks for the directions! I have replaced my 512k factory RAMs with two 1GB PC2-6400S-666-12 modules that had been scrapped from iMacs, and my D630 is now awesome compared to the sluggish performance I’ve had under Vista.
Great site!

Also you may have to run CMD prompt in elevated mode, ie hold cntrl and shift and select cmd after typing cmd in search (for bcdedit command)

eg bcdedit /set increaseuserva 3072 will increase RAM available to apps to 3gb and leave the rest for the OS, you can use any number here though. Windows 7 and Vista only

Hi
Just to let people know that in vist and Windows 7 the command BCDEDIT, will help you to allocate RAM to applications vs OS, usefull since the default is 50/50 and you may want to give more RAM to a heavyweight application, eg a game, or high end graphics program, or you you have a alot of programs running

Excellent. Thanks Tech

Randy,
I’m not sure why all those pictures disappeared. You can use pictures from a guide for Dell Latitude D610 laptop. Most memory replacement steps should be very similar. Here’s the link:
