Problem with my system recognizing memory

Hello everyone,

I have a Dell XPS 8700 running Windows 7 Home Premium Edition (SP1). I understand that the Home Premium Edition of Windows 7 is capped at 16GB, but I purchased an additional 16GB of RAM in anticipation of Windows 10 coming out.

I have (4) Corsair Vengeance 8GB DDR3 sticks of RAM installed, but under system details, it says that I only have 24GB of RAM instead of 32GB installed. I tested each memory stick and they work, but why is it not displaying the full 32GB?

I would appreciate any help.

Thanks

    Hello,

    It says the same thing under the BIOS (24GB). I noticed that if I remove all of the memory and leave one stick in the first slot, it shows up as 8GB; however, when I add another one to the matching slot, they each go down to 4GB.

    I checked to see if I could edit the memory section in the BIOS and it doesn't allow me to.

    I'd appreciate any help.

    Thanks

    Hi,

    What is the size of RAM that's detected in BIOS ?

    Are you currently using Windows 7 or Windows 10 technical preview?

    Thank you

    Hi,

    Can you please check if they are DDR3L or just DDR3 memory modules.

    Thanks.

    Corsair recommends the CML series for the 8700 and not the CMZ. It's important to determine what the manufacturer recommends, especial for Dells, which are somewhat picky.

    So there's nothing I can do to fix this other than purchasing the CML type?

    Thanks

    As Corsair says you need the CML version, it's the best thing to do. As you purchased the wrong modules, Corsair may not want to exchange them. Most RAM suppliers base the return privilege on you getting their recommended modules. Why do you need 32 gb? The only thing you can do with that much is video editing. Almost no apps will need anywhere near that much.

    That's precisely why I need it :) Video editing.

    I'll see what I can do, thanks again for the information.
