Problem SLI Msi 970 and INNO3D 970

Hi

I thought id ask here before I smash my PC up...... Ive got an MSI GTX 970 and an INNO3D 970, on the ROG Maximus Ranger 7 board with windows 10 64 bit. Both cards work fine. Ive SLI the cards, they both show up in windows and in the NVidia control panel ( 2 X gtx 970 ) but it wont enable SLI? says sli disabled and wont give me the option to change it. Ive uninstalled the drivers ( removed everything ) tried 2 different SLI bridges but nothing, updated the BIOS of the mobo..... Anyone help?

Thanks

Yeah I thought that, but ive SLI before with different makes and its been no problem, seems as though people have mixed views in general on mixing brands.

Both brand new ones, one came with the ROG board

Any idea what the problem could be????? I'm sensing something Windows 10

Doesn't the pci express run both lanes at 8x? I wonder if the bios is set to 16x for the main slot and not auto clocking it down so they both run at 8x?
