If you want a working miner for cuda7.0 this is the correct branch: https://github.com/tpruvot/ccminerI tried to compile my fork for the cuda 7.0 and started modding a bit. But the compiler wasn't good enough. Not worth the effort.. Around 10% drop in hashrate in all algos.. If you have time please run tvprovot's cuda 7.0 version of quark and compare the hashrate with my 6.5 release 54-git and post your findings. So you mean CUDA's toolkit 6.5 is better for compiling than 7.0? I'm currently using 7.0 not sure if I should downgrade.

i will fully skip the cuda 7.0... and never made any release with it for that, 7.5 is different
I just fixed a few problems with it...

If you want to use my fork you need to downgrade. Cuda toolkit 7.0 is producing an exe file wich gives error in the hash. (doesn't work) and it's much slower.

Getting 71 MH/s using that miner compared to yours with 93 MH/s. Could anyone try to compile and run my latest git with cuda 7.5? Is the hash still broken? what is the current speed compared to 6.5

So until there is some undertsanding of what is happening and how to get our perf back, it isn't a good idea

@sp_: Your latest git does not compile with cuda 7.5 on Windows (and likely not on *nix either). There's a problem with Hefty causing the following error message: Error 6 error : 'cicc' died with status 0xC0000005 (ACCESS_VIOLATION) The top men on IRC had also found this error already, and I understand there's at least 2 solutions, cutting out Hefty entirely, or modifying it so that the compile can succeed. I don't think either solution has made it into anyone's git yet. You should stop by IRC sometime ![Cool](https://bitcointalk.org/Smileys/default/cool.gif) For those with working versions, so far it looks that cuda 7.5 speeds up some things, and slows down other things. Mixed results all around, so really just for the adventurous for now...

Mixed results all around, so really just for the adventurous for now... need to remove the shitload of "#pragma unroll" in cuda_hefty1.cu (especially the double loop) and it works fine compiling with "-Xptxas --def-load-cache=cs -Xptxas --def-store-cache=cs " might help also a bit to lower the difference I just committed the change to my lyra release github/djm34/ccminer-lyra in principle cuda 7.5 give a +100kh/s on gtx980 (getting up to 2630kh/s on my card OC) +60kh/s on gtx750ti (from 1140 to 1200kh/s on my card) and using the compilation option allows the 780ti to run at 2.8MH/s instead of 2.1MH/s (however must keep in mind that with cuda 6.5, the 780ti is faster and does 2.9MH/s)

@sp_ I changed your latest from git as djm34 suggested, removing just enough #pragma unrolls to allow compile to succeed. I then compiled fresh with both cuda 6.5 and 7.5. This is the Quark performance I get on Windows / 980: git-6.5: 19.2MH/s git-7.5: 18.9MH/s All in all, looks like a minor drop for me. I'm not convinced that these figures are entirely accurate, as it would take me much longer to do a reliable benchmark, time which I can't afford at the moment. Other algos might be broken, I only briefly checked Quark. linux doesnt have the heavycoin hefty problem
Ha! I missed that one ![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif) Linux ftw then ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

(that's how it works on windows at least... it seems they hesitated a lot before releasing cuda 7.5)

Currently I'm using ccMiner 1.5.54-git SP-MOD on 2x GTX980 and I achieved around 18.5MH/s per card running quark algo. All default setting except +100MHz on GPU Core clock - with default power limit since I want to keep both temperature and wattage low. Is the hashrate I'm getting good? ![Cool](https://bitcointalk.org/Smileys/default/cool.gif)

If you compile the latest version or wait for release 55 you will get a small increase in the quark hash. My gigabyte 970 went from 15.8 Mhash to 16.1 Mhash on the standard clocks.
