Extensa 4620 memory upgrade

Just bought an Acer Extensa 4620-6456 with 1MB ram (supposedly 2 512 MB) but researched it before purchase so I also bought 2 1GB DDR2 667MHz modules for an upgrade. When I opened the back I could only find 1 ram slot filled with 1 stick; also I run Belarc Advisor and it says I only have 1 slot filled with 1GB stick. I need help resolving this - do I need to return the 2 ram sticks and buy 1 2GB sticks?

According to the manual up to 4gb on two .soDIMM for model ex4220 only.SO yes. I would  take them back and get one 2Gb strip. Download and read the manual first, in case I missed somethng.

Not enough memory


You can't increase the video memory on a laptop...as games update/upgrade, the video requirements often increase as well. So, what used to work with less video ram won't now.

You could try decreasing the number of video colors your system displays - for example from 32 bit to 16 bit. You'll see what I'm talking about when you open the properties for your desktop and click on video settings.

Problem with upgrading my acer extensa 5620z memory to 4GB


Hi there.
I recommend you get another stick of SODIMM to replace what seems to be the faulty stick.
If you are using XP or Vista X86 (32bit) then the system will only recognize 2.8 - 3GB of memory, only 64bit operating systems recognize the full 4GB.


Good luck ad thanks for using FixYa!!
