What are the model, current ram size and max ram size supported by this laptop? [duplicate]

I boot into a live Lubuntu usb on the laptop, and run lshw see below. (Please help me remove private info in the output, if I miss to do so. I have only removed serial numbers. Anything else I miss to remove?)

Is it correct that it currently has 4GB RAM?

What is the maximum RAM that the laptop can support?

  • Is the model of the laptop "C55Dt-A (PSCFWU)"? Following that, I found at https://www.crucial.com/usa/en/compatible-upgrade-for/Toshiba/satellite-c55dt-a-(pscfwu-03p005) which says "Maximum Memory: 8GB".

  • If I search "C55Dt-A" instead, I found max 16GB RAM support at https://www.cnet.com/products/toshiba-satellite-c55dt-a5305-15-6-a6-5200-4-gb-ram-750-gb-hdd-us/ and https://support.toshiba.com/supportmodel/PSCFWU-02000D (https://support.toshiba.com/support/staticContentDetail?contentId=4004241&isFromTOCLink=false)

What is the correct max ram supported by the laptop? What is the model of the laptop? Thanks.

Based on what you posted, it looks like:

  1. You have 4GB of memory.
  2. You have a Satellite C55Dt-A (PSCFWU)
  3. So your laptop can take up to 16GB of memory.

But that's based on what you posted. I would personally trust lshw, but you can get a definitive answer even if you don't.

Find the serial number on the bottom of your laptop and type it into https://support.toshiba.com/ . I'm sure it will tell you what model you have.
