Acer laptop slow when new ram added.

Answers

  • What I would like to know is if the notebook is still slow when the two rams are connected, when the power plan is in high performance? If the slowness still occurs, you should replace the ram with another one.

    Are they connected now? Because the slowness no longer happens but my memory has not changed.
     
  • Apparently the two ram memories have similar characteristics. Was the problem solved by putting the power plan into high performance?

    I dont think so. There are no noticeable changes
  • So the problem of slowness still occurs?

    It just doesn't seem to recognize the added ram.
  • Have you checked if the bios information tab shows 8gb of ram?

    Where would I find that? Sorry for not knowing anything.
  • Restart the computer and press f2 before the acer logo.

    Nothing seems to happen. Do you mean before the logo pops up?
  • Yes, press fn + f2 or just f2 before the acer logo to access the bios.

    I cant seem to do it. The logo pops up instantly
  • When you open the task manager, do 8gb of ram appear?

    No need to apologize, none of us knew anything at some point :)

    As for your situation, although both sticks are similar (they adhere to the same standard specification) they may not be compatible when used together. Sometimes even when you get a stick that has the exact same primary timings there's a chance of it not working in pairs because of different sub-timings, that's why it's recommended to buy kits instead of single sticks.

    It's usually no problem to match one stick with a similar one, and I know for a fact that Intel's memory controller can deal with some craziness (no experience on mismatched RAM and AMD though), but things like what you're experiencing can happen.

    Another thing that comes to mind is the machine firmware, maybe it's not compatible with the Samsung stick you have, I've seen the firmware updates that allow the use of certain RAM sticks.

    Check that the laptop is up to date in that regard by downloading the latest one from here and going through the installer (while using the original RAM and connected to the wall adapter please). If it were using an older one, it would be updated.

    And best of luck, if it doesn't work that way I'm afraid there isn't much else you can do :anguished:
  • @aphanic I was thinking of something related to ram density as well.

    @aphanic I was thinking of something related to ram density as well.

    Yep! That too, it's been a while but some machines refused to work with some RAM sticks depending on their density, it brings me back to my Pentium III 800MHz days!! =)

    Anyway, there's another program that can give us more information on the RAM sticks you have @Zeethe. There's a free version that's more than enough for what we need since we don't want to override anything, just read. You can grab it here: Thaiphoon Burner

    You may get a warning when starting it stating that your firmware prevents you from doing some things that you can disregard, it's expected (it'd be odd that you didn't get it). Then click on Read and select each bank if you have both sticks installed or only the one if you only have one of them, you should see an output like this:

    Thanks for all the help. The task manager does show 8.0 GB. When I open Thaiphoon Burner it says that the version of ROM file is not newer than that of BIOS. AT this point I'm kind of done but thanks guys.
  • Acer launched in June a new version of the bios, see: https://www.acer.com/ac/pt/BR/content/support-product/8065?b=1
