 Posted: Wed Jun 14, 2006 8:23 pm Post subject: SLI mother board + 2x6600GT geforce graphic card |
 |
|
Hello all guys,
I have a DFI lanparty motherboard, that supports SLI.
Its chipset is nforce4 and on it there are 2 x Nvidia Geforce 6600 GT PCI-E graphic cards. But... does linux support SLI yet?
Is there an how-to, to make it work?
Thanks for helping =) |

I have a DFI Lanparty UT NF4 SLI-DR Expert board using a single PCI-e 6600GT. I can't speak to the SLI mode, but I haven't been able to get the nvidia drivers to work at all.
So.... |

In the link I posted in my last answer, we can read:

How can I determine if my kernel correctly detects my PCI Bridge?
As discussed above, the NVIDIA driver must have access to the PCI Bridge that each NVIDIA GPU is connected to in order to configure SLI correctly. The following steps will identify whether the kernel correctly recognizes the PCI Bridge:
*
Identify both NVIDIA GPUs:
% /sbin/lspci | grep -i vga
0a:00.0 VGA compatible controller: nVidia Corporation [...]
81:00.0 VGA compatible controller: nVidia Corporation [...]
*
Verify that each GPU is connected to a bus connected to the Root Bridge (note that the GPUs in the above example are on buses 0a and 81):
% /sbin/lspci -t
good:
-+-[0000:80]-+-00.0
| +-01.0
| \-0e.0-[0000:81]----00.0
...
\-[0000:00]-+-00.0
+-01.0
+-01.1
+-0e.0-[0000:0a]----00.0
bad:
-+-[0000:81]---00.0
...
\-[0000:00]-+-00.0
+-01.0
+-01.1
+-0e.0-[0000:0a]----00.0
Note that in the first example, bus 81 is connected to Root Bridge 80, but that in the second example there is no Root Bridge 80 and bus 81 is incorrectly connected at the base of the device tree. In the bad case, the only solution is to upgrade your kernel to one that properly detects your PCI bus layout.

I have last Kernel, is there a way to solve this? Bad configuration? |
