[NAME] de Oro   MXM is not PCI-E form factor so I don't understand "right card" The sub compact unit in your picture has a riser card which if I'm not mistaken cannot be added to a model that shipped without a discrete GPU. Eurocom MXM-to-PCIe x16 adapter lets you put a laptop GPU inside of a desktop PC that is a full size tower. [IMAGE] [NAME]-Chris M  would have more information. [IMAGE]  
I made a mistake and ordered a RTX 3000 from eBay, which ended up being a MXM model, without a PCIe connector. I am wondering about the correct model or part # for Quadro RTX 3000 that's compatible with Precision 3240 Compact and that has a PCIe connector.
Precision 3240 Compact - Quadro RTX 3000 part number?
