nvcc fatal : Unsupported gpu architecture 'compute_70' about ccminer HOT 6 CLOSED

Go to solution properties -> CUDA C/C++ ->Device -> Code Generation and remove the compute_70,sm_70 at the end.
Then you could add compute_20,sm_21 or whatever your card is.

But it's unlikely that it will work because there's code that is not compatible with older cards.
Maybe try an older version from tprovot from about one or two years ago:
https://github.com/tpruvot/ccminer

By the way, any card you can buy now will be way faster than your old card.

I did that step and it led me to this error. 62 of them.

I tried to go to an old version, downloaded one from August 18, 2016.
Extracted that one, opened the sln file with Visual Studio. Got the first error similar to the one I made in my first post that it could not read the ccminer.vcxproj file because it was looking for BuildCustomization path, this time CUDA 7.5 , so I changed that to 8.0 since that's the CUDA Toolkit I installed.
Soon as I did that I kept getting an error that "An item with the same key has already been added."
I called myself editing the vcxproj file there, and just deleting out the ExtensionSettings and ExtensionTargets all together to get passed that error. When I went to Rebuild Solution, I got ALL KINDS of Errors.

A newer nvidia video card is in my future, but not at the moment, I just recently picked up a newer AMD graphics card and ebayed these Quadro cards as I wanted to see what use I could make of them mining Altcoins.

Can you find your cards in this list here?
https://developer.nvidia.com/cuda-gpus
Everything with compute capability 3.0 or more should work, I think.
In a few hours I have more time, then I could send you a project file for CUDA 8.0

My card is on a different list from that page, it is, 5th item listed under CUDA-Enabled Quadro Products

from ccminer.

Try this vcxproj file:
ccminervcxproj.zip
With the latest ccminer code (https://github.com/KlausT/ccminer/archive/windows.zip) it compiles, but I think many algos will not work.
I didn't look at tpruvot's version yet.

Wow it compiled with no errors. Thank you.
