@yun9999 or anyone else with the Sapphire Fury cards.

I have 15 of them with all the same settings (-96mv) 900/400 15.12 driver and the last one I bought won't under-volt in Windows 10. Has anyone else ever experienced this before?
This is what I have tried;
moved it to a different rig with 5 other Fury's and it will run Optiminer but Claymore will return a error saying the GPU returned incorrect data.
moved it back to the new rig with 3 other Furys and it will crash the driver in about 30 seconds of mining with Optiminer
   reinstalled windows and new drivers - same
   installed 16.3.2 drivers - same
   UEFI Bios and standard - same
moved it to a independent computer, ran graphic benchmarks on default settings and no errors - but when I under-volt it, crashes the computer.

Every setup has more than enough power overhead, running TB 85 or H81 boards - except the independent PC (supermicro server)

I purchased it at Newegg but to send it back, I believe they would test it and it would pass there tests because how many gamers really under-volt that much.

Any suggestions
