So I bought this card on Craigslist... (always a good start to a story.) Listing was a bit unclear, said 760 in one spot, 760Ti in another. Card is completely unbranded, black 760-style reference shroud. Since the 760Ti is pretty rare and apparently OEM-only, I figured it was most likely just a 760. From what markings there are I've concluded it is an OEM Dell/Alienware 760 Ti. Unfortunately the only port that seems to work in my 5,1 CMP (El Cap) is the DVI-I (paired with a GT 120 for boot screen.) Nvidia drivers are installed and IDs it as a "GeForce GTX 760 Ti OEM." I get nothing on Displayport, DVI-D, or HDMI. I tried the card in two other machines, Ivy Bridge era. Z68 Gigabyte board - No bios/splash screen, nothing on windows boot. (on any port.) Z77 Quo (hackintosh) board - I get Quo bios splash screen on DVI-I, nothing on any other port. Won't progress beyond that and I can't enter bios setup or boot loader. So I have no idea if the card is defective or if there is some Dell-specific firmware on this thing causing problems? BIOS/UEFI issue? I have no idea what the Alienware would have shipped with. I mainly bought it for the CMP, so I can use the DVI-I as-is, but it would be nice to have more than one port. Since that probably isn't going to happen I would eventually pass it down for kids' minecraft duty, but it won't boot at all in those machines... Would consider sending to macvidcards for flashing, but I don't see a 760 Ti on their menu. And I'd hate to throw good money after bad if the thing is a dead end. edit: also tried inZ77E Asrock (UEFI) - Boot screen and boots to Windows only on DVI-I, nothing on any other port. So obviously it is happier with UEFI. But still only having one port working is not ideal.
