If you follow the link, scroll down and look at compatible systems, you will see a list of all supported machines including the Precision 5820 XL.
How were those machines compatible with one graphics card and not the others, I would not know.

Hello,
first of all, all firmware updates offered by dell are working only on cards manufactured for dell ( or hdd/ssd sold as dell parts ).
For cards manufactured by others, either check if the maker has some update or if nvidia has something directly available.
Secondly, the bios of the computer must also support resizable bar, and as far as I know, is not an option offered in the 5820/7820/7920 bios
