Dedicated GPU in Dell PowerEdge C1100
- by Eli Gundry
We recently purchased a Dell PowerEdge C1100 off lease with the initention of using it for graphics processing. We installed an AMD HD 7000 series GPU in it that runs off of board power and it sends video to the display. That said, the video is very choppy, leading us to belive that the onboard video is doing all the processing and sending it to the card. Is there any way to either disable the VGA on this server or tell the OS to only use the dedicated card.
More info:
The server is running REHL 6.4
The graphics running the proprietary AMD drivers
The video card only works in OS and does not show the BIOS on boot (we know that it's impossible to change this)
Any ideas, guys?
Update
We are now thinking that the GPU is doing the graphics processing, but not working at the full speed of the PCI bus. Which is odd, because it is an x16 slot, but probably optimized to use a RAID card (if that makes any sense).
Is there any way to remedy the choppy graphics on this server?
