problem with crossfire since omega 15.3s

[Jaswan]

hi,

i hadnt used my PC for a while now, but i ended up getting a couple of new games, so before installing them i updated to the omega 15.3 drivers.

now, i hadn't noticed a problem before this, but that doesn't mean it wasn't there before hand. . .

so i tried out far cry 4 and dying light (i have since seen there is an official issue with dying light) and both seemed a little sluggish. so i fired up afterburner to use the riva tuner stats thing and in both games my second card is sat at 300mhz core and 0% load.

so, i have uninstalled cleaned and re installed a few times now and still according to CCC my second card is "disabled" and i have no crossfire option.

anyone had this or have any idea what it is?

TIA

Jase

i have also tried alien isolation an that is the same, its as if i only have one card installed.

i will see if i can roll back

thanks

from africanos23s advice, i looked at the power cables from the psu, i think there was an issue there, but i have now split them so that each feed from the psu goes into the first plug on one card and the second plug on the other (if that makes sense)

the option has returned!

cheers all

Jase.
