>>the soldered RAM limits the amount of total RAM that can run in dual channel mode
Can it affect running 3d modelling software, like CADs or Blender, on an integrated graphics card with shared (dynamic) memory?
As mentioned here [1], at least on a Dell XPS laptop while diy upgrading soldered RAM, it is necessary to resolder a resistor from 1 to 0 position on
the board to tell BIOS what RAM to expect.
Maybe for E14 thinkpads it is also possible to perform a similar thing, to diy rewire the board to ignore the malfunctioning soldered RAM and use the socketed RAM instead. But how to get all the original thinkpad system board schematics?

- commoner 4y agoRAM in dual channel mode performs better than RAM in single channel mode, but you would have to run benchmarks to measure the impact. I'm not sure about the extent of the difference in the 3D modeling software scenario. I remember seeing that article when it was posted on HN. The stencil alignment looks very intimidating and the entire process is obviously much more difficult than a SO-DIMM replacement, but it's good to know that upgrading soldered RAM may be possible in some cases for those willing to take on the challenge.
- amts 4y agoI've just seen on google (on askubuntu) that it can be possible to make Ubuntu ignore soldered RAM and use the socketed RAM instead. https://askubuntu.com/questions/1428808/can-i-disable-one-slot-of-ram https://askubuntu.com/questions/1428808/can-i-disable-one-sl... "There isn't anyway to disable RAM as far as I know, but there is a way to have Ubuntu ignore the bad RAM, but you need to know the addresses of the RAM in question." Can someone evaluate the plausibility of this?
