What is the Correct format for Dual ATI CARDS.

[Pool]

Hi,

I've currently got two XFX 5870's on a GA-X58-OC board. I've always used the standard DSDT from Tonymac's site. But I've just bought a AV reciever and when using this with my Hack I don't get Audio because I'm limited to HDMI/Optical connections and this board doesn't have anything except HDMI. So I decided to try editing my DSDT to allow HDMI audio.

I followed a great guide which allowed me to get one graphic card setup and recognized correctly and the HDMI works. But I can't find any help on inserting another card into my DSDT.

I did try myself but my System Profile shows both cards in the PCI slot 1 and the PCIe width as x8 instead of x16.

I will paste my dsdt edit later cause I'm in work at the moment but basically its something like.

PCI0
PEGP
GFX0
PEG0
GFX0
HDAU

Any help would be appreciated or it would be great if anyone could show me a guide for dual ATI cards. Cause i don't know the difference between PEGP/PEGO/POP1 lol.

Thanks Toleda, its now a little different from the screenshot above I've completly removed my edits for the second card. The mac is reporting it as a 5000 series.

Lane capabilty is function of the slot used. Verify slot capability in the manual. Assuming @3 and @5 are x16 slots, suggest:
PEG3@3

GFX0​

onboard-1​

HDAU​

onboard-1​

PEG5@5

GFX0​

onboard-2​

HDAU​

onboard-2

Method (_DSM, .... is fine for GFX0/Uakari

I tried this Toleda and they still both show as being in PCI slot 1.

They are also both in the correct slot for x16

Cosmetic, you can figure it out.

Ok i found out how to edit your PCI Slots, for me the code is


Device (PEG5)
{
Name (_ADR, 0x00050000)
Name (_STA, 0x0F)
Name (_PRW, Package (0x02)
{
0x09,
0x05
})
Device (GFX0)
{
Name (_ADR, Zero)
Name (_SUN, 0x02) -------02 = PCI Slot 2
Method (_DSM, 4, NotSerialized)


Now i just need to figure out what to add/change for the Lane width x16 issue.
