    Default u25w internals

    I need to upgrade the ram in my u25w. I find no pictures of the internals. I know the ram is beneath the "motherboard".

    When I remove the board from the case, is it going to disturb heatsink compound? How is heat coupled from the cpu to the case?

    While I am at it, I would like to increase the capacity of the SSD. I know the SSD is a mini mSata, half length. The SSD is 32 GB, what options do I have here? These things are scarce as hen's teeth.

    Going up in size lengthens the time before wearout.

    Anybody got links to pictures of the assembly and underneath the motherboard?

    Thanks

    It's got a single SODIMM socket buried in there somewhere. And I think it maxes out at 4gb. It's on the side of the mainboard smashed against the top of the case. So it requires a full disassembly to get at it.

    You're right about the SSD too, and it's VERY hard to find those short length SSDs. And no, you can't put a longer one in there... simply will not fit.

    Docs for the Lanner NCA-1010 say ram max is 8 GB in one SODIMM. Yep, it’s on the cpu side of the pcboard.

    Yes, but it's extremely picky when you attempt that. So be ready to buy several before you get one to work.

    I’m partial to Crucial.

    As an aside…

    There was a guy in Idaho back in the ‘50s that said What can we do with all these potatoes? His name was Bud Simplot. He is the father of the frozen French fry. He developed the process of blanching the potatoes and flash freezing them.

    He made a ton of money from his invention.

    He looked around as said what else can we make Idaho. Well we don’t have a lot seismic activity, let’s make memory chips. He started Micron Technology, the parent of Crucial.

    At one point they were the only domestic memory manufacturer.

    So Simplot went from making one type of chips to another type of chips.

    The SODIMM are unbuffered. If you have multiple chips in parallel, the extra capacitive loading may skew the timing.

    What is the form factor on the SSD?

    It's a 42mm M.2 SATA slot, not NVME, SATA.

    I guess I should answer my own question posted in this thread.

    Taking the pcboard out of the u25w is easy. Heat is coupled to the case by a pad that is attached to the case and presses on the cpu center. The cpu package is ballgrid array reflow soldered to the pcboard.

    I’ll see if I can take some pictures to document this.
