  • Welcome!

    I'll get straight to the point.

    When I started Pop!_Planet, I launched it because I saw a need for a centralized community for Pop!_OS. To be frank, I never expected the level of popularity it has achieved. Over the last year, we have gone from under 50 users, to almost 400 users. That's awesome! However... it also comes with a downside. We are rapidly running out of disk space on our server, and the bandwidth costs go up every month.

    Pop!_Planet is not affiliated with System76 in any way, and is funded completely out of pocket. From day one, I said that I'd never use on-site ads (I hate them as much as you do), so the only monetization we get is through donations. Right now, the donations we receive don't even cover our overhead.

    I know that most users will ignore this message, and that's ok. However, if even a few of our users are willing and able to donate a few dollars to help offset our expenses, it would be greatly appreciated.

Question 50% of RAM not being detected

Hi guys,

I've just got a new budget laptop and installed Pop on it. So far it seems to be working great apart from the fact that it's only detecting 2 out of 4GB of RAM and is therefore going into overdrive when ever I have a few programs open at once. I'm looking to upgrade the ram at some point anyway but I'm not sure why Pop doesn't seem to be using one of the channels?

Can anyone help?

There is some difference between Rams, width 64 bit and 8 bit, one is Sodimm LPDDR3 that is used by laptops another is Dimm DDR3 that is used by PC. So either your BIOS have some issues or your memory is incompatible with your PC or it can't work with which other. Did it work previously with another system?
If not, try to use only 1 RAM stick in 2 different slots, then only another RAM stick in 2 different slots, maybe try use eraser to clean the contacts of your RAM (Don't push hard when cleaning contacts).

Well, both modules are detected, but for some reason 2GB is not being utilized. Couple of questions.

1) Did you install the second 2GB, or was it included with the system?

2) Does this system have discrete video or onboard "vampire" video? If it's the second, it could be configured incorrectly and is taking up 2GB of your system memory.

EDIT: Your screenshot above answers question 2. Onboard video. Check the BIOS or EFI setup. Make sure that the onboard video isn't configured to take up 2GB.

Sometimes the amount of RAM reported will seem to be slightly "off" from what you know is in there - example, My Thinkstation S20 has 8GB but htop says it's 7.77 GB. That's just down to how it's calculated. This isn't that problem :D
