Which systemboard for a Precision M3800 has a thunderbolt port not just a minidisplay port?
The system board on my precision M3800 died. I purchased a so-called replacement, which turned out to be from an XPS9530. The marking on the side of my laptop indicates my original system board did not have a thunderbolt port, just a mini display port. (no lightning bolt, just a D with a dot in the middle) I would like to replace the system board in my precision M3800 with a motherboard equipped with a thunderbolt port. I have found 4 different system boards being offered:
PPPP8 , CRVX3, and NY4TF, all of which have 4 usb ports like my original system board. Pictures of the these three boards show a manufacture date of 9-26-2013. The forth system board V9191M has 3 usb ports and a manufacture date of 10-7-2014.
What is the part number or other identifying mark which signifies the system board is for an M3800tbt i.e., with a thunderbolt controller? Are there system boards having four usb ports and a thunderbolt port?
Your help is much appreciated.

The part number for the Thunderbolt motherboard is V919M. It also has a different base cover, part number 6KM9V.

Could you please elaborate between the different 4712 models. All are M3800 4712HQ i7 but what are the differences?
Dell M3800, P/N PPPP8 or 97F45 or NY4TF?
Kind regards

@Life Unlimited Fyi this thread is 3 years old, and the Precision M3800 was never available with Thunderbolt. It's true that Thunderbolt 2 could run over a Mini-DisplayPort connector, but the M3800 never had Thunderbolt 2. In fact to my knowledge no Dell systems ever had TB2. I believe Dell's first Thunderbolt implementations involved Thunderbolt 3, which uses a USB-C connector.
In terms of differences in motherboards, one possible difference is the presence or absence of a TPM, since some parts of the world do not allow them. But I can't speak to those specific part numbers.

Appreciate the response. Not too concerned regrading TPM (Trusted Platform Module). Or should I be? Reason why I asked previously, my M3800 4702 died and I would like to replace it with a 4712. By all comparison it looks like it can work and I have a lot of experiences with these XPS 9530 and M3800 models. All I need to know is which replacement MB to purchase. Or is anyone OK?
Do you know what the differences are between the PPPP8 or 97F45 or NY4TF models? They are all the 4712 2,3Ghz 4XUSB ports
I don’t mind reformatting and install new OS and drivers.
Kind regards
