If you are interested in using an eGPU (DIY ViDock) solution with a particular laptop, it can be REALLY hard to wade through 500+ pages of eGPU info over at the notebookreview forum! So, here are a couple brief excerpts to make things easier for Dell notebook owners. Make sure to checkout the original thread pages (at the source links below) for more info!

Relevant portion for M6400 owners…
I’m attempting to install an HD5750 (green) card into a Dell Precision M6400. This laptop has 12 gigs RAM and an NVIDIA Quadro FX 3700M (on board).
I’m into my 2nd week of attempts and can’t get passed the error 12. I’ve tried every combo of setup 1.x I can come up with.
Your system has TOLUD = 3.5GB (PCI BUS starts at E0000000), meaning there is no free 256MB pci-e space to accomodate a eGPU. You can only have a 3GB installation OR run the XP drivers (no DX10/11 or aero) where you disable the FX3700M. That would be a ‘dGPU off’ command in Setup 1.x’s startup.bat. You’d be booting blind until the HD5750 kicks in.
You are seeing the exact same issue as the Dell E43x0/E6x00/E6x10 folks have as described at. I’d suggest petition Dell to fix this as otherwise your expresscard has limited functionality.
