As above - just got mine today. A very tight fit in my compact precision!

When i do an lspci -v i cant see the card...has anyone else done this yet??

Cheers.
 
are you sure the card is fully inserted in the pci slot? if yes, does it show up anywhere in 'dmesg' ? (you can post/attach the output here)

if it's not in dmesg and lspci, and it is fully inserted then the only possibilities i see are:
  1. there is some bios setting to disable that pci slot
  2. the card is broken
 
Definately working. Usually its headless on a shelf...connected it up to a screen and went into the bios....i also set the graphics option from auto to, what its seen as "Intel (HD)" so im quite sure the card is ok...
 
can you post the output of 'dmesg' and 'lspci -nnk' ?
 
Sure - heres lspci -nnk

Im at work at the moment but over the weekend i can remove the ssd' and put in another to test on - install windows and see if it see the video card.? (im a novice) so thats the only simpleton test i can think of...
 
Has anyone managed to install a B50 yet that you know of...? Am i right in saying that Proxmox doesnt see it atall?
 
Just found this after a-googling.... (reddit)

"Getting it working: The Dell came with old bios, so had to update that first as I had issues getting the B50 recognized. Added bonus was microcode fix as its a raptor lake chip. I also had to enable rebar in the BIOS as it came off by default. I also only have a 180w PSU which is too low for this system but enough to get started, I picked up a 240w but it seems to crash regularly with this supply and i suspect its faulty, 180w is working great for now."

not sure what the "rebar" is though!

yeah, i have one right here, running with proxmox ve 9.1 and it detects and works fine


as already said, check the bios for settings, and try with a e.g. ubuntu live iso to see if it's there at all

rebar refers to 'resizable bar', e.g. see here: https://www.intel.com/content/www/us/en/support/articles/000090831/graphics.html
 
Ok so when you black list how do you do that....im a little confused when it comes to the intel (graphics) stuff. All that ive got working at the moment "kind of" is the onboard card which in windows gives the yellow triangle.

When youre whitelisting/adding an Intel video card how does the system/ProxMox differentiate between card and onboard video?
