HP Compaq presario CQ43: not enough ram in my computer

My HP Compaq presario CQ43 has 2 GB of ram. I want to get 8GB. It is 64 bit and it's hard to run most programs because of the ram being such a small size. It will support 8 GB of ram? If I take out the old 2gig and put 8 gig will perform best?

According to the manual, yes it can accept up to 8 GB memory DDR3-1333 SO-DIMM. See this video on: 33 in there where is flush with the memory. This technology never removes the memory but you just spread the retaining clips and remove and then follow again. See the second video.

You have 2 slots, so you need the modules of 2 x 4 GB like this:

4 GB (PC3 10600, 1 333 MHz) 621569-001

Yes, 8 GB of memory will be a major improvement. Better upgrade would be to replace the mechanical drive with an SSD. After back if you are interested by this.

  • Compaq Presario CQ43

    Hello

    I have a Compaq Presario CQ43-102AU and have thought about updates.

    Is it possible to upgrade the processor and the RAM?

    Thanks in advance

    -Mike

    Certainly an AMD processor can only be upgraded to another AMD processor with the same PIN architecture. He must position the slot in the motherboard. And it must be recognized and compatible with the BIOS of the laptop.

    I have now found your product, but HP has not yet posted the Service Manual online, which gives a list of compatible processors.

    Here are the specs:

    http://h10010.www1.HP.com/wwpc/NZ/en/Ho/WF06b/321957-321957-3329742-89318-89318-5059078-5104994.html

    I see that you have 2 GB of RAM. Since you also have Windows 7 64-bit, you can easily switch to 4 GB of RAM DDR3 - 1333 computer laptop memory which should be available quite cheap at any computer store. Passage of 2 to 4 concerts will make a world of difference in reactivity.

    I would stay away from trying a processor upgrade. The laptop is too recent, and it could void the warranty. I'm sure that you have not paid much for the laptop, and you can probably sell for close to what you paid and get a faster. The unique processors for laptops cost as much as half of what the laptop costs. It is a laptop low end budget and is hampered by a weak graphic system, even with a faster processor, it will not be much you can do with him. If all you are doing is internet and office type work that's fine.

    Hi again,

    You can still install, make sure just that take care you of your images, and your personal files and then go for the installation of Windows 10, 64-bit.

    All you need to do to re-setup is to download the Adobe Creative cloud application and then you can install LR and PS since the Application itself.

    No need to pay again, it will recognize your id and password and allow you to download the applications that you are already a member of the subscription.

  • Error: Not enough RAM to open small files

    MacBook5, 2

    Macintosh OSX 10.6.3

    4 GB OF RAM

    NVIDIA GeForce 9400M - 256 Mo

    Adobe Photoshop CS4 Extended (11.0.1)

    I am TIFF of Maya files which are 11880 x 3400 pixel.  The ranges of between 100-160 MB file size.  Whenever I try to open one of these images in Photoshop, I get this error: "Could not complete the command open because there is not enough RAM."

    I just ran Adobe Update and I have all the updates.

    I deleted my Photoshop preferences and restarted Photoshop.

    I have my drive from Scratch on an internal SSD drive to 30 GB of free space.

    I have 3000 MB of RAM to Photoshop.

    Despite all this, I always get the error "Could not complete the command open because there is not enough RAM" every time that I try to open the pictures made out of Maya.

    The images of Maya are normal TIFF 8-bit with alpha channel, or a channel depth.  I can open them with success in After Effects, but this is useless for me.  I need to edit them individually in Photoshop.

    Photoshop error is clearly not due to the size of the file.  I HDR panoramas with superior to 11880 x 3400 dimensions ranging up to 1 GB in size of the file that I can open and work on in Photoshop without any problem.

    Why Photoshop doesn't play well with these TIFF images?

    I received another complaint about it and looked at a sample file.    Maya apparently written the TIFF file as a large compressed tile (against the suggestions of the TIFF specification.).    If this tile is greater think Photoshop so that he may reasonably, safely allocate a buffer, it will get an out of memory error.

    The big problem is: there is no update "reasonable buffer" size for 64-bit.

    I am testing a fix for this now.

    But there's always bigger that Photoshop can read and Maya tiles needs to fix their code TIFF for use strips or tiles to avoid excessive buffer sizes.

  • Compaq Presario CQ57-104TU: upgrade Ram, memory (Ram Hynix PC3L-12800)

    Hello world

    I have a Compaq Presario CQ57-104TU. I recently decided to upgrade the ram (currently 1 x 2 GB Elpida PC3 - 10600 1333 Mhz). I bought 2 x 4 Gb Hynix HMT451S6AFR8A, PC3L-12800. Unfortunitely when I install the new Ram (Hynix)

    the computer does not start. Is there something I can do or the Ram is not compatible?

    Any help would be appreciated,

    André

    Here is the Service Manual:

    Manual

    See p.2. Specified memory is DDR3-1333 1.5 volt and you try to install low-voltage DDR3-1600. In addition, memory that you are trying to install is high density, because it has 4 blocks on each side, where I am betting that original memory was of low density (8 blocks). Long story short, it is not compatible. It do you no good to install DDR3-1600 by the way. Best of cases, it will anyway be downclock speed 1333.

  • My computer is old and I am poor. Not enough ram for new ff! What can I do?

    Hello. I have windows xp, a very old hand e-machines computer and only 368 MB of RAM and a processor intel of 3.33 GHz. Even on this very old version of firefox, I get a lot of error messages and crashes. I had a newer version but had to come back to this one, because there are too many bugs!

    Now I get messages that my version (3.6.8)will soon be unsupported and have no security. I am very poor;  I have no money to buy a new computer with all the latest bells and whistles just so that firefox will work: 1 gig of ram is Not gonna happen on THIS computer. SO... what do you suggest we poor folks do?
    

    I liked firefox for years, but it seems to take place in the direction of Microsoft went: bulky, heavy programs, tons of software needed alongside more memory, tons of things, we don't want TO not but should have anyway. I guess that if you do not have terrabites now, you're not cool. This saddens me and excludes a large number of us who are poor.

    It comes to my feedback and a call for help. I hope you ask my questions and tell me what version of Firefox, I can go to that will be supported for more than what I currently have. Firefox keeps getting slower and slower, the more is invented. I use it mainly for youtube videos, email and search and watch the other vids, I can barely do at home is no longer. I don't want to go, but if I have no choice. I also wish a lighter application that is very light on my limited resources. I have a lot; just a search bar; don't need even toolbars, other applications like google. Is this possible. even if I've had enough of everything for firefox 8 (which I did not)?

    Thanks for any help you can give.

    Do a cleaning (re) install and delete the folder of the program Firefox (C:\Program Files\Mozilla Firefox\).

    Download a new copy of Firefox and save the file to the desktop.

    Uninstall your current version of Firefox if possible.

    • Do NOT remove the data of a personal nature when you uninstall the current version or you lose your bookmarks and other data in the profile folder.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.

    Your bookmarks and other profile data stored in the Firefox profile folder and will not be affected by a relocation, but make sure that you do not select delete data of a personal nature if you uninstall Firefox.

  • Not enough (RAM) memory free to start treatment for Outlook services

    When I run Outlook 2007 SP2 and after getting my new one e-mail a notice appears of the outlook on the outlook bar icon to say tasks cannot start treatment services because there is not enough free memory to run this program (and it I do not see my new email). I added 2 GB of RAM and now have 6 GB in my Dell XPS 420 desktop computer. It has no effect on the error message. I'm running the 32-bit version of Windows Vista Ultimate SP2. In the physical memory in task manager, I show about 3100 MB in total, 1500 cache and 0 free. Don't know why the total would not be about 6 GB which is what is installed. What can I do to manage the memory or any other suggestions for the prospects for a return to normal?

    It turns out that the problem was with Outlook and not related to the memery computer. It was solved by going to features, programs and Control Panel, and then repair Microsoft office system 2007.  Thank you for all your help.

    Hello

    32-bit Edition of Windows Vista has a limit of 4 GB memory. If you have installed more than 4 GB, Vista will not read the extra memory.

    The question you have posted is related to Outlook and would be better suited to the office community. Please visit the link below to find a community that will support what ask you
