Crossfire or not??

[Streetlight]

Hi there.

Wonder if someone could help me, As I am having trouble Crossfireing my 2 R9 290.

Wonder if I have bought the right motherboard. as Crossfire is not coming up in Catalyst Control Center.

One Card runs at 1000 core 1250 mem
And the other 1000 core 1300 mem


I5 2500k
Asrock Z77 PRO4 M
850 cosiair
Clean install of Windows 8.1

You're motherboard supports crossfire just fine , make sure you have the latest bios update for the board, remove all the drivers and run DDU or driver sweeper, remove the second card and install the latest catalyst drivers, then install the second card.

Give that a try and let us know how you get on.

The first thing i would do is when the drivers are installed for the second card make sure you restart the PC. The same thing happened to me, my second card wouldn't show up so i restarted the PC and like magic it showed up in CCC

Pretty sure that mobo only does x16/x4, but that obviously wouldn't stop xfire working.

Darket's advice should sort it out. Fingers crossed

So I got he latest Bios, Removed all the drivers(DDU worked very well)..

Removed the 2nd Card...

Install 14.4...

Added the 2nd card...

Still nothing....

What's under the gaming tab in CCC?

Just 3d application settings...

Hang on, lemme bang my head for a bit and see what falls out. I swear I've had something similar to this a while back...

Oh Matthew!

Yes, few times to make sure.

when you added the second card did windows install the drivers or did you manually install them?

Which slots are your cards in? The manual mentions putting the cards in PCI-E slots 1 and 4 - you haven't got them in 1 and 3 have you? Might be worth trying the second card in the other slot, just in case the instructions weren't translated correctly.

Maunally install them.

 

[Uncle Petey]

I always install drivers for all cards at once. You kind of have to with WC though.

Have them in 1 and 3, Card won't fit in 4 as its a Silverstone SST-SG10B.

was going for a small build.

maybe I should just crossfire my two 2 280x for this small build?

 

[Uncle Petey]

I think slot 3 is only x1 which may explain things.

- 1 x PCI Express 3.0 x16 slot (PCIE1: x16 mode)
- 2 x PCI Express 2.0 x16 slots (PCIE3: x1 mode; PCIE4: x4 mode)
- 1 x PCI Express 2.0 x1 slot

I think that's your problem. Looks like your board only allows Crossfire if the second card's in slot 4, not if it's in slot 3.
