Selectadock III Graphics Card Compatibility

#1 Post by NineVolcanic » Sat Feb 21, 2026 12:22 pm

Hello I have a question:

I currently have a Selectadock III setup with my 770X. From what I gathered in my research, the best possible graphics card to use is a Voodoo 5 5500 which I have. However, it doesn't seem like it fits. Apologies if this is a novice question but I'm unsure if what I read is incorrect or if there is a step I'm missing. Is it possible to fit one of these in?

SelectaDock III supports PCI version Voodoo 5 5500 which is rare, I'm afraid yours is AGP version.
You can take a look at your card and check if there is an "L" shape without gold finger, if so, it's a common AGP version.

Late reply to this thread. I spent some time researching graphics card compatibility for the SelectaDock III way back 20+ years ago, and as far as I know the details there are still correct:

The PCI version of the Voodoo 5 5500 is definitely compatible with the SelectaDock III: I had one installed and used it for several years. And it was the best card I found that worked with the SelectaDock III.

As panips notes, you may have an AGP version, which won't fit in the PCI slot. The AGP versions were more easily available than the PCI versions back in the day. The Voodoo 5 was always somewhat rare, though, and now it must be near impossible to find at any price, so I doubt it's worth trying to look for a PCI version, if you don't already own one.

Note that in my experience the Voodoo 3 was almost as good for most games that I was actually playing at the time. And the PCI version of the Voodoo 3 works great. There are lots of other constraints that limit gaming in a docked 600/770 Thinkpad in a SelectaDock system which prevent a Voodoo 5 from reaching its full potential no matter what other hardware you put in the system.
