I have worked for 2 days trying to get an XFX RX 460 GPU drivers to be recognized in a Dell Precision T5400 workstation. I upgraded the T5400 from Vista to Windows 7 64 bit.

Things I have done:

Installed GPU into the same slot as the previous GPU
Installed GPU as if it was a mining machine with riser card and PCI express slot.
Changed "Digital Signature" per forum on a Help page
Changed PATH statement to reflect location of drivers
Installed Drivers in separate AMD folder
Installed Drivers in the Program Files / AMD folder
Rebooted the machine like a million times.
Installed .NET Framework updates
Installed SP1 and other Updates
Installed using supplied DVD
Installed using downloaded file from AMD website

The Device Manager shows the yellow triangle next to the device driver.

Funny thing is, I successfully installed an XFX RX 470 externally and it worked amazing!

Has anyone else solved this problem? FYI. I am trying to get this ready for my son for XMAS morning.!  Images of the errors messages are found below.

Dear Claymore. Thanks again for a great program.

Question please. Should the start.bat file for the Zcash miner use the SET or SETX at the top before each GPU_**** statement?

Thanks in advance

It's past the 30 day return policy. I'd have to ship it back to the factory in perfect condition.

I was thinking of getting one of these from Amazon.

Question.

I made a mistake when I purchased my first mobo (ASRock H97M Anniversary )for mining Etherium.

 The description said 6 slots, and I thought it was 6 PCI slots. I purchased 6 GPUs, and now I am 3 slots short. Can I use an Ebay find, which is a
PCI Express to 3 or 4 slot USB adapter card to add the extra GPU's? Or do I have to purchase a whole new mobo, and start from scratch?

Thanks in advance.
