Ati CrossfireX

[Jonnygrunge]

Guys I have two 6950's in CrossfireX (6970's unlocked shaders GPU core 1.175V)
can anyone explain why with crossfire I don't get all the options in CCC?
These being MLAA, Tessalation, etc it's bizarre!
Please see attached screenshots.
The first is of my CCC:

The second being one I got from a website:

Turns out in the Class key in Local Machine in the registry,
the info on the cards was corrupted, a standard driver subkey was still present after after driver install screwing up the card detection on ATi installation.
I fixed this, by removing all the subkeys apart from 0003 a standard driver. I then ran driver sweeper in safe mode,
re-installed the driver and now keys 0000 - 0005 have proper information in them,
and the job is now done, CCC displays all the options!
Phew!

Off to get some kip now!

I'm not at home to check but I don't recall seeing the disable amd crossfirex power settings on mine. I believe this disables ULPS from what I can gather which I have been doing manually through regedit. Is this option now showing up for you jonnygrunge?

No the ULPS do not show up! Got one of the reference photos from a website to compare! But the Tessalation, and MLAA settings are now all there and with the reghack to bypass the limits my shader unlocked cards now run at 900/1375!
