To the linux guys: what version of CUDA are you compiling with?
6.0 ... we have been playing with 6.5 and it seems to work quite well ... our miners are now all running 6.5 compiled ccminer and they seem to be stable ... but the moment a major crash happens - we revert back to the 6.0 compiled miners and they just work ... #crysx CUDA 6.5 -- The stuff from SP_ compiles on CUDA 6.5. I believe that tpruvot moved to CUDA 7.0, but he takes pains to keep his miners compatible with older nVidia cards. I don't personally know if CUDA 7.0 can compile programs built for 6.5 properly, although I am curious. I would install CUDA Toolkit 7.0 on my system if it would work well with the code SP_ produces. CBuchner's CudaMiner was written for CUDA 5.5, tpruvot has a version re-written for 6.5. I'm looking forward to moving to CUDA 7.0, especially if it produces more hash. --scryptr same here - though cuda 7.0 is not compiling anywhere near as compliant as 6.5 is ... for now anyway @scryptr ... should be interesting to see how this all works a few months down the track when nvidia change the whole playing field with a new chipset once again ... #crysx

I have added another 9% in skein. Most gain on compute 5.2. Will clean the code abit and submit to github
the 970 is now hashing at 265MHASH.
The total gain from version 46 on the 970 is 38%

Added keccak boost.
Keccak can now be run with intensity 28, before only 21 was possible.
defaults are set to 27 for compute 5.0 and 28 for compute 5,2

I am running 6X750ti EVGA SC (no OC) and for quark when I run -i 22 I get 36744. When I add -g 2 or any number of threads my CPU goes to 99% and I actually run slower at about 36100-250. I have tried the release 46 and also compiled my own using commit 757 and both go to 99% cpu.
I am on windows 8.1 Pro with an i3 processor with 8 GB of RAM.
Just tried 47 and without an -i or -g parameter I get 3653337120
When I try -i 22 or -i 21 it crashes.
I get nonce errors
[2015-04-26 13:04:34] GPU #5: GeForce GTX 750 Ti, 38196 kH/s[0m [2015-04-26 13:04:34] GPU #4: result for nonce $769C2CC7 does not validate on CPU![0m
Then this
Cuda error in func 'cuda_check_cpu_setTarget' at line 28 : unspecified launch failure.
EDIT: Rebooted and now it works up to -i 23

gtx750 oc'ed
#47 vs. Commit 742
skein 83210 vs. 83620 quark 5810 vs 5824 (hashrate fluctuating, maybe incorrect measuring)
conclusion: commit 742 is best for me ...

For skein you should use the latest version. Fixed some bugs in the hash. Checking 32 bits was not enough. Increased to 64 bits.

RELEASE v47--
Quick Quark stats:
GTX 750ti FTW: 6.32-6.5Mh/s per card, 38.4Mh/s for 6x750ti rig
GTX 960 SSC: 10.1Mh/s per single card in a work computer with low load
GTX 970 FTW+: 14.8Mh/s per card, 29.2Mh/s per 2x970 rig
Error rates are greater. The last release, v46, could run for hours at 99%+ acceptance rates. Now, I am getting mid-90% acceptance, early on.

The as-compiled by sp_ release 45 is a nightmare on my rig, mining Quark GTX 970 i7 4770 16GB Win 8.1 Unsteady hashrate with -i 20, and most any other intensity setting crashes. After a crash, the GPU goes into a low power mode and I have to restart the machine. I suspect that if I used an older version of Afterburner or Precision X that has the K-Boost button, I might be able to wake it up after the crash without restarting . Either way, it is very buggy and that makes me ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) download nvidia inspector Use bat-file with nvidiaInspector -restartDisplayDriver Nvidia inspector is an OverClocking application. Does it have anything to do with recovering from a crash?DRIVER CRASH-- I am often able to overcome a driver crash with EVGA PrecisionX 16, an overclocking utility. If you drive the card to hard, and the driver crashes, the card can be reset by turning "Boost Clock" off and on and then re-applying the clocking settings. The desktop display may also need to be reset, as well. --scryptr Thanks scryptr. But what I just installed was TdrDelaySetTo40 that I found in nvminer zip folder. It hasn't crashed yet. But when renting hash and not able to monitor all the time I needed something to restart the miner right away. He is the problem I was having or still maybe have. At that time the command window was still open and if I clicked the warning window off the miner would start mining again without any problem. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs26.postimg.org%2Fjjzud3twl%2Fimage.jpg&t=665&c=lAH4cTX7_HtH6Q) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs26.postimg.org%2F4mrdc3go5%2Fimage.jpg&t=665&c=aR0XJNKEi172Pw) thx EDIT: This happened a lot when the stratum failed and at the goto loop. Tested it by disconnecting the ithernet. :loop ccminer.exe -r 1 -R 5 -a quark -o stratum+tcp://us-west01.miningrigrentals.com:3333 -u me -p x -d 0,1,2 ccminer.exe -r 1 -R 5 -a quark -o stratum+tcp://us-central01.miningrigrentals.com:3333 -u me -p x -d 0,1,2 goto loop nVidiaInspector -- The program is a GOOD ONE for Windows! It overclocks and is NOT LIMITED to 4 CARDS! I am able to access the settings on all 6 of the GTX 750ti SSC cards on the Windows rig, save the settings in a shortcut, and place the shortcut in the Startup Folder on my rig. Fan speed, clock speed for core and memory, and power settings are all adjustable. I added 500kh/s to the rig's Lyra2 mining hash rate with the utility (4.5Mh/s now). @tbearhere -- I also get the Windows warning "ccminer has stopped working" when it cycles through the batch file. It requires manual intervention and disrupts the functionality of the goto loop. Apparently, it is a more frequent problem in Windows 8. I don't have a solution yet, I am still looking. --scryptr

He also had a timeout switch that would restart CudaMiner after so many seconds. Yaamp has a looper that will cycle through the top paying algos. I revised it to reflect the actual performance of the cards with up-to-date software, and posted a bunch of pages back. --scryptr
