All I know is you can't upgrade the power supply. I wanted to upgrade the video card (for more Display port slots), Geek Squad said it was not doable as it's fixed in position or something like that. However, I believe you can upgrade the SSD and RAM (not sure on how many slots).
Sorry, there was a problem. Please try again later.It has four slots. I know for sure that it can handle up to 128 GB of ram. I have 64 GB installed and have two open slots remaining. I recommend configuring with two slots to begin with so you can upgrade later by just popping in two more ram sticks at a later date. I did that for both XPS 8940 PCs I bought.
Sorry, there was a problem. Please try again later.The system has four UDIMM memory slots. The maximum memory supported in this system is 128 GB.
