Sure. It has latest dsdt, ssdt and kexts I am using. I did not include any additional utilities to keep it small. You can always download them elsewhere or let me know what you need and I'll upload it for you.

I dunno, I can't find a GFX string for it, and almost everyone else I've read who're using the GTX 260 are using GraphicsEnabler and it works perfect. That's what I used before on my old motherboard and it said x16. I ran nvclock and it says I'm "Current Rate: 8X, Maximum Rate: 16X". So, I think it's either my card, or it's some issue with the 10.6.4 drivers like some people have mentioned. I tried using LegacyAGPM and set up an iMac11,1 section with the GTX 260 section from the real AGPM's MacPro4,1 section, and it hasn't made a difference. It actually does seem like the card is running in power save mode all the time. If a launch a game, nvclock still says 300Mhz, when I should be at 626 right? At this point though I've just about hijacked this thread so I guess I ought to start a new one.

Edit: I did just try an EFI string instead of GE, and it still says x8. It's gotta be either my card or my motherboard. Obviously x8 is still plenty of bandwidth for the GTX 260, and everything else is fine, but I don't like that it's not working the way it's supposed to.

Slayer how is your new card? I was thinking of going the ati route, still on the fence

Power save mode actually does make sense. I did have this problem initially (lower clock but still x16 PCIe) and started to look dipper into it. But then when made all the necessary changes to my dsdt it magically disappeared so I did not look any farther. Here is my NVClock info if u'd like it for reference.

And you are right this does not have anything to do with this thread and there is already plenty of info on this subject.

Yeah looks just like my output but I have the 216 superclocked so some clocks are higher in mode 1 and 2, and it's definitely stuck on mode 0. I ran some stress tests and it didn't budge past 300Mhz. Is your DSDT just like the one on page 24 or does it have other stuff?

The dsdt file I posted on page 24 is still the latest and the one I am running right now.
PS FYI It is not just dsdt. It is a combination of dsdt and ssdt. There are tables/references in both and in some cases ssdt takes a priority. But most of the changes I've made are in the dsdt.

Interesting. I added the SSDT files (I don't fully understand the concept behind them, I guess just more of the same as DSDT) and put in dropssdt=yes, and now my gpu clock is at level 2 (626Mhz for me since I have the 260 superclocked ), but, unfortunately I'm still at x8 lanes. Actually now it even clocked down to level 1 at 400Mhz, so that's good too, but STILL x8 lanes. I've got another week to return the board if I need to, and I just remembered my zotac ion has an x16 2.0 slot so I could test the card on that if I feel like tearing that machine apart to fit it on there.
