"Headless" Mining GPU for gaming

[gouca]

Hello,

 

just shopped an ASUS P104-100 Mining GPU off a Black Friday discount for $200. What caught my attention as a non miner were the hidden display outputs. There was a lot of discussion around the ASUS model and its possible use as a regular GFX. A couple of early reviews had mentioned those I/O-ports but failed to verify their functionality so I took the risk, bought the card, and now I'm stuck with "a gimped" GTX1080. 

 

Here's GPU-Z information. Note the BIOS-limited PCI-E 1.1 X4.

 

Apparently those I/O-ports are mechanically functional; they emit electricity as per usual and they're properly installed. See the gallery here. Yet there's no display signal since the display engine has been - most likely - shut off via BIOS. I tried, without success, to play around with similar BIOS ROMs to activate the display engine, yet the 4GB GDDR5X memory fits no other regular GPU and therefore wouldn't be stable in any case.

 

Now my question is, could I utilize this GPU - with another card as a display renderer - in some other way via an unofficial SLI-project or similar stuff? My setup is MSI X470 Gaming Plus paired with a Ryzen 2600 and my primary GPU is a GTX 980 Ti.

 

All the help appreciated!

The only thing I can think of is the "FreeSync on nvidia GPU" thing that recently made the news. Bad news is I think people only have it working with AMD APUs so you would have to downgrade there to enable it.

PSA: this GPU is literally an ASUS TURBO-GTX1080-8G (with 1920/2560). Had someone open and inspect the PCB; the GPU has 8GB of GDDR5X of which half is disabled in BIOS among the display engine. Force flashing Turbo's BIOS should make this function.

Did you get to test this (with the forced bios-flash)? Did it work?
