Hi folks,
Im a bit stuck on an issue, where my lspci output is not showing all 4 of my GPU cards. Before I go any further, below are my configuration details and what I have done so far.
Problem:- Only the 2 out of 4 GPU's are visible in the lspci output.
- 2 GPU's which show in lspci output, are both in the PCIe 16x slots.
- However, Remaining 2 GPU's in the PCIe 8x slots are not showing in lspci output !! Wtf!?!?
Objective:- Make use of 4 cards in my system, either individually or by using crossfire.
Hardware setup:- Intel i3770k + 4gb Ram
- Gigabyte Z77A-UP7 Motherboard (Factory firmware)
- 4 x Gigabyte ATI Radeon HD7970 (Factory firmware)
- 1200watt Thermaltake PSU
OS Setup:- Ubuntu 64bit 12.04.2 Server
- Kernel: 3.5.0-27-generic #46~precise1-Ubuntu SMP Tue Mar 26 19:33:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux (uname -a output)
- AMD Drivers: amd-driver-installer-catalyst-13.1-linux-x86.x86_64 (compiled against 3.5.0-27 kernel headers)
- AMD APP SDK: AMD-APP-SDK-v2.8-lnx64 (compiled against Catalyst 13.1 drivers)
Tested:- Ran through the BIOS and verified all configuration options were enabled (from what I could tell)
- Verified all cards are powered and working (All fans spin up and they're all producing heat)
- Tested all cards individually plugged into the PCIe 16x slots, verified lspci output showing card details
- With all 4 GPU's plugged in and running:
- - aticonfig --adapter=all -f --initial (Still no success, only showing 2/4 cards)
- - Creating an mpgu chain and enabling crossfire configuration, connecting the crossfire ribbons etc. (Still no success, only showing 2/4 cards)
- No change to lspci output after running: sudo update-pciids
I am absolutely stumped on this problem and I suspect this issue could be Kernel and/or motherboard chipset driver support related.
From what I understand, regardless if the kernel modules are loaded or not - lspci should still show a list of hardware devices it has detected.
The next logical step in my trouble shooting, would be to compile a kernel from scratch, and everyone knows this is a painstakingly laborious task which I would like to try and avoid
Im hoping that someone else out there has ran into a similar problem and might be able to point me in the right direction.
