In this guide I explain how to upgrade memory (RAM) in a Dell Inspiron 9300 laptop. This model has two memory slots available for upgrades and both slots are accessible from the bottom of the laptop. Even inexperienced users can upgrade memory in a Dell Inspiron 9300 laptop.
Let’s do it step-by-step.
STEP 1.
Turn off the laptop and remove the battery.
Remove couple of screws securing the memory cover. Remove the cover.

STEP 2.
Under the cover you’ll find two slots. In my case both slots are occupied by two 256MB PC2-4200 RAM modules.
In order to remove the memory module you’ll have to carefully spread latches on the sides. The memory module will pop up at a 20-30 degree angle.

STEP 3.
Pull the memory module from the slot. Do the same with the second module.

You can install up to 2GB RAM in a Dell Inspiron 9300 laptop. Each slot can take up to 1GB module. You can use DDR-2 PC2-4200, PC-5300 or PC2-6400 modules.
In my case I’m using two 1GB PC2-5300 modules.
By the way, you can install different size modules into different slots. For example, you can keep one of the 256MB modules in one slot and install a new 1GB module into the second slot. In this case the laptop will see 1.25GB.
STEP 4.
Install new memory modules into the memory slots. New memory should be detected and configured automatically. You don’t have to change anything in the laptop settings.

When you turn on the laptop, it will display the following message: “The amount of system memory has changed.”
The laptop may freeze temporarily at this screen. Do not turn it off, just wait.

After a while, you’ll get another message: “Strike the F1 key to continue, F2 to run the setup utility”.
If you press on F1, the laptop will start loading Windows.
If you press on F2, it will take it to the BIOS setup menu.

In the BIOS setup menu you can confirm that both memory modules are detected and recognized correctly.
As you see, in my case the BIOS sees 2GB RAM running at 533MHz.

Hey all,
I have had hte same problem with the Dell 9300 upgarde to 2GB. The solution that worked for me (however drastic and overkill it might be) was to re-install windows and switch the RAM right before the re-install. Worked like a charm and 9300 running quicker than ever now. Hope this helps!

Hi,
I am having a similar problem mentioned above. Crucial 2x1GB RAM causes Win7 to hang on boot. Any solutions out there? Would reformatting with Vista or XP make a difference? Thanks.

@ Jordan,
It’s possible one of the new memory modules is defective.
Try removing new memory modules one by one. Will it stat properly with only one 1GB module installed? Try installing them into different slots.

I upgraded to G.Skill 2x1GB DDR2 PC4200 and it won’t boot. Running Windows 7 32bit and it runs fine with the 2x512mb, but not with the 2x1GB. I can get it into safe mode fine, but gets to the loading Windows logo and sits and swirls forever.

Upgraded an Inspiron 9300 in seconds with these instructions. Worked perfectly with 2x1GB. Many thanks indeed.

Is it possible to upgrade a Dell 9300 Inspiron to 4GB of RAM?
I just purchased 2gb DDR-533 PC2-4200 form my mini 10 but found out the memory is only good for the 10v. When i purchased they say it is compatible with the 9300 inspiron. I know this requires pairs. If I purchased another could I upgrade my 9300 Inspiron to 4GB of RAM?
If so… Would I need new BIOs and what version?

Im also having the same problem as JoyBell. I have a Dell 9300 w/ windows 7 I bought my ram thru
dell 1gb ddr2 pc2-6400 x2 the computer recognizes the new ram, but windows won’t start. I have bios version A05 dell doesnt have an update. I spoke w/ dell techs and they told me that I should use
pc2-4200 i dont think that is the problem. I think its windows 7.
Thanks

Thank you.

Pam,
Unfortunately there is not much you can do to fix the faulty memory slot. The slot is soldered directly to the motherboard. There are many small connectors soldered to the motherboard. Most likely one of them is bad and has to be resoldred. I don’t think that you can do it at home without special soldering equipment. I’ve never done it myself.
You’ll have to use the laptop with only one working slot or replace the entire motherboard.
By the way, you can try this trick: http://www.laptoprepair101.com/laptop/2008/02/28/fix-laptop-memory-slot-failure/
