Gainward GTX 970 Not Working

Hi, this may sound confusing, but bear with me.

 

I inherited a faulty Gainward Phantom GTX 970. When installed into a system it would prevent the system from booting.

 

When plugged in and default graphics output is set to the IGP, the system would boot, but Windows would not detected it and neither would the BIOS flashing tool nvflash.

 

When observing the boot up process, the cards fans would begin fast, then slow down to a slower speed. Because of this, I suspected it may have been a BIOS issue on the card.

 

Through hours of experimentation though, I could not get the card to be detected by anything.

 

Getting frustrated, I tried unplugging one of the PCIe power cables and... A message on the screen telling me to plug in all power cables.

 

With this knowledge I believed the card wasn't completely destroyed.

 

Skipping over failed attempts to short out pins on the BIOS chip, I ended up setting the PC to boot from the IGP with only one power cable plugged in.

 

When booting to Windows, it surprisingly showed up in device manager! Now that I have access to it, I opened up nvflash, downloaded a BIOS for my card and, lo and behold, it allowed me to flash the BIOS!

 

I then turned off the PC, plugged in the cards and... nothing!

 

With further toying, I found I wouldn't get the error message IF the first PCIe plug was plugged in. If it is plugged in, I get no message advising to plug in power cables and it doesn't get detected in Windows if booting with the IGP.

 

Would anyone have any idea what may be happening? It seems to pertain exclusively to the first power input but I'm not entirely sure 

 

(Btw I've tested different computers and different PSUs to rule out either)

 

Any input would be greatly appreciated

My idea is toying that card for real (to it's internal parts)

Haha yea I wish I could, just don't really know what I'm doing, especially cause the only electronics equipment I have is a multimetre, which is faulty.

 

Damn shame cause my 760 carked it completely, and was given this faulty card cause I can't afford to buy a new card haha #UniStudent

You see, an 8 pin power connector is just a 6 pin with 2 extra ground connections. Maybe you can wire the ground cable of the first 6 pin and all cable of the second 6 pin into a an 8 pin connector from the PSU. an 8 pin gives the same amount of power as 2 6 pins, so this should work if the power check function doesn't disagree to this mod.

Hmm interesting...

 

I might give it a go and see what happens, cheers for the idea!

In my country it's $202 (used), to upgrade my LGA 775 system

The rx 580 and 1060 are better, new, with warranty and better drivers

Yes I know 4GB is enough for BF1, look at my signature for the plan of upgrade
