Question about HP Pavilion ze4540IUS (ZE4540US) PC Notebook

1 Answer

Upgrading RAM I want to upgrade my RAM. When searching the internet sites they tell me that I can use SO-Ram rather than SD-Ram. Is there a difference? And, are they compatible. I currently have 250 and want to upgrade to 1g. The computer has two slots so I will be replacing anything that is in there currently.

Re: Upgrading RAM has a great scanner that will scan your system and tell you what kind of memory is installed and make suggestions as to compatible pieces. I actually buy from there, but even if you don't their scan tool works really well.

    Upgrading acer laptop RAM

    You Can Actually Upgrade This To 2 Gig Memory.
    Each Slot Will Take 1 A Gig Strip.
    I,d suggest Buying another 256 mb Strip, To Put Into Slot 2.
    Or Buy a 512mb ( Half Gig ) Which Will Give you 750mb With your Existing Strip Already In There. ** Recommend 1 Gigabyte Max** 2 gig of Ram in This Baby Would Probably Start Glowing.
    You Can Buy DDR/266/333 In 256/512/1 Gig Strips. These Are Commonly Known As SD-RAM-Modules.

    Acer's support isn't the best. IMHO But go to their support site anyway and look up your laptops manual (there should be instructions on upgrading your RAM there). I did find that your machine will accept up to 4GB of RAM 2 X 2GB sticks. There should be a door or port (for easy user RAM upgrading) that is being overlooked, but again it is an Acer.
    Good luck.
