Upgrade 4GB ram on NB550D-109
Posted: 22-Jun-2012 20:41

Hi

I have upgraded my Nb550d-109 with 4gb ram but it work only 2gb usable.In properties show 4gb and right next to that (2gb usable).

I have upgrade my bios, search msconfig and see if the boot advenced options is ok.
What i must do for my ram work better.
I have seen on web that might be from on-board chipset.

Anyone?
Thanks

Why do you think your netbook must work with 4 GB RAM?
Have you found any info that you can upgrade your netbook with 4GB RAM?

You cannot force notebook to work with 4GB RAM if this is not supported on mainboard.
As far as I know it is upgradable up to 2GB of RAM and compatible RAM has part number PA3856U-1M2G.

It's a question of System:
W7 Starter supports up 2GB
W7 32-bit - 3,2GB
W7 64-bit - 4GB

Netbook supports 4GB of RAM.
If you wany to use more than 2GB you have to change your OS to Windows 7 Home Premium at least.

Event if you do that you will could use only 3.2GB of RAM. If you want to use more than 3.2GB you have to install 64-bit version of Windows 7 but there is no drivers for 64-bit architecture.

Sorry for my bad English and I have hope that I help.
