rebuild for older cards.

[Novicracker]

How do I rebuild for older cards. I'm using 2 Geforece GT 610's and 2 Geforce GTX 760's on 2 different machines. And I would ;like to get them running. Just for the fun of the learning and satisfaction that they are doing something rather than sitting on a shelf collecting dust. lol. I'm no programmer. So How do I change the version of cuda that I can get the program to recognize the cards. I know they wont hash hard at all but it will be fun to learn this.

GTX760 should work as it is. For the GT610 cards we have to build ccminer with CUDA 8 and add sm_21 support. Are you using Windows or are you using Linux?

[Novicracker]

I am using Windows 10 64-bit.

Hey Klaust I'm not sure what sm_21 support is. Can you please explain it for me?

Try this version: ccminer-821-cuda80-with-sm21.zip Some algos will probably not work with your GT610.

The sm number is also called "compute capability" and is telling us what kind of hardware your card has. sm_30 are Kepler cards, sm_50/52 are Maxwell cards, sm_61 are Pascal cards, and so on.

thanks man!!!! Also the GTX 760 didn't run with the newest version. Ill try this one with it.

ok man I tried each device and no luck, according to Cuda Wiki the GT 610 has a Fermi processor and it supports Cuda 2.1 on its release. And the GTX 760 jas a Kepler processor and supports Cuda 3.0 on its release. https://en.wikipedia.org/wiki/CUDA I'm not sure if this helps or anything. I do appreciate all the help man. Once I get a real mining machine Ill have to donate come coin some coin.

I tried CCminer on the Cuda Developer Drivers I'm going to uninstall them and install the latest drivers and get back to you.

ok on the GTX 760 I am getting ERROR: no algo or invalid algo. I have the -a x16r set in the .bat file. So I'm guessing its not the -a setting but the actual algorithms that are built to run the card. So how would I compile the correct memory specific algos? if you can tell me what I need installed in VS Studio and how to set it up for this I will share my algo's so you can add them to your project.

[KlausT]

My ccminer version doesn't support x16r, that's only in tpruvot's version. I don't think you can add it yourself, it's not that easy to make the changes. But you could use the skein algo, that would run on your GT610 I think. If you only use the GTX760 you could use neoscrypt or lyra2v2.

If you insist: Install Visual Studio 2015 Community Edition: https://my.visualstudio.com/Downloads?q=visual%20studio%202015&wt.mc_id=o~msft~vscom~older-downloads Install CUDA 8.0: https://developer.nvidia.com/cuda-80-ga2-download-archive Now you can either fork my repository, or just download the source code.

[Novicracker]

In the install for Visual Studio there are other repositories will I need to install any of these or will a naked install do?

I'm going to try and fork your repository and add the x16r algorithm. And see if I can get Cuda 7.5 to work with the GT 610 2g. Now when I add the x16r files into the build is there anything special I have to do to get the algo to be utilized by the main exe? I'm not a programmer so this is all new to me.

Thank you @KlausT How can I change the SM version from inside of VS? where you define SM in vs project? I can't find it.

[KlausT]

Project -> properties -> CUDA C/C++ -> Code Generation If you have more than one version of the CUDA Toolkit installed, then you can select one in Project -> Build Customizations

[arman4343]

Thank you for your help @KlausT . I find it.
