Are these GPU's viable?

Pryderi

Thanks a ton!

Don’t wanted to start new topic :)

I have couple old cuda 1.3 based nvidia cards. And have PCs to run them (power is no problem coz they always on anyway). Any ideas how I can use them? ccminer supports only cuda 2.0… I can run cudaminer with scrypt, but because of asics they produce no solutions just heat :)

You could try to compile cudaminer yourself, with the old cuda libraries.
The source code is at: https://github.com/cbuchner1/CudaMiner

Had that idea, but I am not programmer :) I know configure/make/make install magic on Linux, but thats all :) And I should have cuda 1.x libraries… Maybe only if I can ask advice if stuck somewhere… :angel:

I have installed MS Visual Studio 2010, CUDA 5.5 Toolkit and tried to compile ccminer…

But no success until now - as I have read on web basing on errors I get, cuda source is written using compute 3.0 and up capability. When I define that I use compute 1.0 I get errors. I tried to remove algos that not interested to me, but that not helped as seems all use these definitions. Will try Kbomba sources that are down to 2.0

Need help from clever persons…

After seeking and trying I found a code that at least start to compile under compute10 setting.
But now have stupid problem and don’t know how to solve it, tried everything seems…

Getting:
“fatal error C1083: Cannot open include file: ‘pthread.h’: No such file or directory”

I downloaded pthreds prebuild library, but anything I do setting it in Linker not helping…
how I should include it in Visual Studio??? Plz help

Well, if you are on Linux you need to install the developer packages of pthread. The pthread library contains the binaries only, not the files needed to link against the pthread libraries.

For windows I have no clue, how to get the header files

google or duckduckgo may help

After many hours of downloading-changing-rebuilding-deleting-trying libraries magic with curl, ssl and other strange names I managed to buil ccminer exe with compute 1.0 … but … it does not work :cry: Simple starting and closing…

Pity… :(

One thing I have learned is - windows guys saying that Linux is very complicated, you need full hell of libraries to run and compile, bla bla… now I know that in Windows is the same or maybe even worse…

Just for interest - in 2 weeks with 3 pcs of 8800GT on scrypt I mined 0.001 LTC :)

well done …
