Hello, I bought a Zotac GTX660 Synergy and the card ONLY works on my Asus Workstation (C600 Chipset / 850W / Old UEFI).
I tried an old LGA775 520Watt non UEFI, a recent MSI B150 Chipset UEFI and on my EGpu system without success.
The card is simply not recognized, the MB bios gui doesn't start at all, black screen.
If I start the system with internal GPU the Zotac doesn't appear anywhere.
Any ideas?
Thank you.
