Which memory slots are used by my laptop

Hi,
My laptop has 4GB of memory which is flashed at BIOS. Due to XP 32 bit, I can only use 3GB. I am now upgrading to Windows Vista 64 bit. Vista is memory hungry and I want to upgrade my laptop to 8GB.

How can I locate which memory modules are installed on laptop? Don't tell me to open the laptop and confirm. I need a software way to locate which banks are used.

Thanks

Try checking the BIOS to see which slots are populated.

First off, you would need to check to make sure your particular model of laptop could handle the 8GB of RAM.
www.crucial.com has something on their homepage that allows you to select the model, etc. and will show you the normal config of the RAM setup, max allowed per slot, etc.
Once you figure this part out, then you can determine which slots are used in the BIOS. There are Windows programs that sometimes allow you to see this info but don't always work with different systems.

Acronis True Image 2019 just released!

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

check the bios. But why not upgrade to Win7 instead of Vista? and why not just look at the module? It is just a little door on the bottom of the laptop in most cases.

We don't know which laptop you have but for a generalisation use one of the hardware checker programs that quizes the system BIOS

SIW for example will give you the module names and configurations and which slots each is in.
Many other similar programs exist.

Get your laptop's manual as a download by going to the the manufacturer's website to check it will both support the additional memory and that the hardware is 64bit compatible (and also that 64bit drivers are easily obtained).

SIW Free Version is bundled with OpenCandy, chose not to install the optional programs when setting it up.

Use CPU-Z. The memory tab will show you how many slots you have, which ones are used and what kind of memory in it and all that.

At the right hand side of the page you'll see the download links.
I recommend getting the zipped version where nothing gets installed. All you need is the exe from the zip file.

Try CPU-Z - the download links are just to the right of the screen grab there.

On the SPD tab it should tell you what each slot reports... use the picklist on that tab to see each slot.

I use SIW.  Used it with a script to inventory dozens of systems and determine what size modules we needed to order.  Not only does it tell you how much RAM is in each slot, it also tells you when it was manufactured and by what company.

I THINK WMI can do this too, but this makes it SOOOO easy.
