Hi all,

I am having a bit of trouble with my crossfire setup. it did work perfectly and i need to get it back working so i can heat my house throughout the winter

first system specs,
cpu 6700k
mobo gigabyte G1 gaming
psu evga 1200 p2
gpu 2x r9 290x
os win10
hdd samsung ssd's in raid 0

ok the first problem I am having
on start up I dont get any of the bios loading information that i normally got, just blank screen until in windows.
what I have tried
disconnecting second card, all displays correctly
plugging monitor into second card, displays correctly when primary display in bios set to slot 2, change connection back to first card and setting in bios and back to no display. leaving the monitor connected to the second cards and changing the settings in the bios back to slot 1 I can still see the bios.
different connections (I use dp) no difference

the second is that crossfire dosent work. it did work until recently i used the AMD driver cleaner and I think that cocked it up.
i have clean installed the latest drivers which hasn't made any difference
i have checked the settings in radeon settings and it is set to crossfire. in assassins creed it only shows one gpu and not 2 like it used to. msi afterburner sees it as does device manager and radeon settings.
swapping the monitor to the second card i only have that card in use.

I am thinking about clearing the cemos but it might kill my raid array (it has done before)
I dont know a cleaner way of uninstalling the graphics drivers. maybe a clean install of windows, but as you know that is a pain in the behind
Has anyone else had any problems with the and driver cleaner?
Can removing drivers affect the bios?

Please if anyone has any ideas let me know

Thanks

Matt

I use display port as well, I find if I leave my monitors on standby and turn my computer on the screens stay black until windows starts to load the graphics driver (it changes when I get to the Windows loading screen). If I turn my screens of completely (i.e press button so there is no standby light), turn the computer on then turn the monitor back on I can see the boot screen.

I'm sorry I can't help you with crossfire. I would suggest taking shutting down, take out the 2nd card completely, uninstalling the drivers, reset, reinstall the latest driver, shut down. Put the 2nd card back in and see if the driver picks up the 2nd card and enable it that way.
 
I forgot what he setting was called but I sure there was something to Disable in MSI afterburner to get Xfire working

"disable ULPS"

seems on other forums, uninstalling drivers as aswell as Afterburner and install all fresh has helped

When you say it does not work, have you tried it in game or benched it with heaven or similar.

If ULPS is enabled it wont always show the 2nd card active until under load in Gpuz/Afterburner etc

Theres also various ways of disabling ULPS it too
 
Hi, thanks for your replies. I have got crossfire working now. For anyone who is interested here is how I did it.

I removed the second card power and from the motherboard, a major challenge with a custom water cooled system. Booted and uninstalled the graphics driver and afterburner. Restarted the computer and ran the AMD uninstall tool. Restarted in safe mode and used ddu to clean the remaining bits of driver. Installed the graphics driver, restarted and tested in a game. Shut down and installed the second card. Booted up and turned on crossfire ( this option wasn't there before I did this) in radon settings. Restarted and tested in game, which was now showing two cards. Reinstalled afterburner added a small oc and synchronised the cards, turned off ulps in afterburner and I am back at the expected frame rates.

Thanks again for your help, I decided to have another go at clean installing the drivers with a card removed (I had tried this before) but ran the AMD tool and got everything back up and running before adding the second card.

I still have the first problem that I can't see the bios when my monitor is plugged into the card in slot 1 even though I have this set as the display in the bios. Any ideas on this? I am less bothered about this, it isn't as much of a problem to move the monitor from the slot 1 card to the slot 2 card.

Thanks again

Matt

Yes the monitor is on standby. If I connect it to the card in slot 2 it works as expected in the BIOS.
Click to expand...

Turn your monitor off when you shut down (so there is no standby light). When you turn your computer on again, wait 1 second and then turn the monitor on and it should display the motherboard boot sequence.

Failing that get into your BIOS by hooking up your monitor to the motherbaords display port and turn off the onboard graphics adaptor via the UFEI.
