Moral, can you take some photos? Maybe we can come up with a solution

[moral hazard]

Ok will upload pics in a few mins.

I'll just mention I've tried several driver version, I even flashed the cards to the same clocks and voltage.

Is there a registry hack to enable crossfire?

Because I know the connector is only for more bandwidth and some desktop cards (low end) dont need it to work.

Sorry to double post, but here are the photos:

The crossfire connectors are on opposite sides of the cards. Also it looks like the ASUS card has 2 crossfire connectors? Very strange...

Spoiler :

Ah, got it, the second one is ASUS. They use a different bridge


Unfortunately, i can't think of any way to physically link them but you can try to hack the registry to force CF:

Change the value for every instance of EnableCrossFireAutoLink to 1 (if 0). You'll find those registry keys right above every instance of EnableUlps, so you can verify the change of all those keys with a DWORD of 1 to a zero at the same time.
Open regedit and search for EnableUlps (F3 until the last one).

So EnableUlps value should be 0 (zero) and EnableCrossFireAutoLink 1 (one).

let us know of course

That was a good idea, but it didnt work in this case for some reason.

I even tried installing a driver for an ati 4670 (because those cards don't need the interconnect), but that didn't help either.

@granyte, I'm having trouble flashing my Alienware slave card to work as a master. Do you mind telling me detailed steps on how you did it? And if it's not too much trouble could you please give me the vbios you're using?

I have no idea why mine won't work as a master.

[granyte]

Yes i will but i need to use mybackup because i don't have my hardware needed to flash and download them.

Well the main issue i faced when flashing was that the master card won't draw anything to the screen if it's not in the master slot. Other then that everythign worked fine

if one could find the pin mapping on each type of card we could attempt to desing a custom bridge.

I ended up selling my asus card.

So now I either need to make my slave work as a master or just buy a new master (Alienware) and the xfire cable (found one on eBay).

I might actually get a master 3870 card and use my slave 4850, bad idea?

[granyte]

they wont work in cfx because they are not fromt he same generation

[moral hazard]

Hmm I should have expected that.

Well then it looks like I'll have to look for another solution.

Don't want to get rid of this notebook but the 7970m is looking tempting (might spend part of my tax return on a new rig).

[granyte]

Ill give you the bios soon.

Have you blind flashed befor?
