Would it be possible for you (or someone else) to compile it with the "#define MAXWELL_OR_FERMI" flag to 0? I would like to use the myriad-groestl algo, but my 780's are getting the insane hashrates with no confirmations bug, as others are getting on non-Maxwell cards.

I tried doing it myself, but Nvidia's CUDA toolkit doesn't recognize Visual Studio Express as a legitimate VS application, so I'm not exactly sure what else to do.

If you could even point me in the direction where I can find instructions to compile it myself if compiling it is too much trouble on your end, I'd really appreciate it.

that one does have the flag set to 0, but doesn't have the spelling error fixed, which may be causing errors

so you need it with flag 0, but what version? (x86 or x64)

on a side note, anyone using nvapi, if you can help me figure out how on earth you can return an NvAPI_ShortString value that would be great, i can not for the life of me get it to return the fullname of the card, compiling is throwing and issue, here is the bit of code, and the error

Code:
NvAPI_ShortString name;
syntax error : missing ';' before identifier 'name'

ooo and ccminer does not mine scrypt

I would like both if possible, but if that is too much trouble, x64 only would be great.

Thank you kindly for your help!

yeh i can see a lot of people are going to ask, here is 32bit and 64bit ccminer 0.6 compiled

Thanks bigjme. Is this Compute 3.5? I tried using your compile with my same old groestl bat file. The performance was worse. From 3100+ kh/s down to ~2450kh/s. You experiencing any difference?

on Windows this should now be built in four flavours, when done correctly Wink

Compute 2.0  with #define MAXWELL_OR_FERMI 1   <-- Fermi
Compute 3.0  with #define MAXWELL_OR_FERMI 0   <-- old Kepler
Compute 3.5  with #define MAXWELL_OR_FERMI 0   <-- highend Kepler and GT630/640 with compute 3.5
Compute 3.5  with #define MAXWELL_OR_FERMI 1   <-- for Maxwell

the flag must be set in both .cu modules with "groestl" in its name. It affects
the speed optimization of the Groestl code.

at some point I will code a runtime selection of the MAXWELL_OR_FERMI flag.

I'm guessing the build bigjme made was for maxwell and that's why my 670 in the system is reporting crazy high hashrate, but is there a chance it's actually hashing between 1-2Mhash? lol  (I normally run separate bat files but I just left it since it looks like I've missed the train on this one anyways)

I just compiled the build straight from github sorry guys.
