What intensity value were you using to hit 5.4MH/s on 750Ti apart from +200 core/mem overclock?

I have some stability problems with two of my "leftovers" nvidia rigs.
One of them are powering down the whole system after mining for a couple of hours and the other one is ccminer just crashing on randomly.
I have identical hardware in all my the rigs (NVIDIA/AMD), mobos, cpu, ram, risers and psus.
In one rig i have one EVGA FTW 750Ti and the other rig i have one EVGA SC 750Ti + Gigabyte Windforce 750Ti.
The one powering down is the rig with two cards.
At the same time i have two rigs running five 750Ti:s each at 36Mhs Quark totally stable for weeks.
This is really annoying because they are also crashing with stock settings on the gpu:s. Temps are really low also so i dont get this.
All systems have fresh Win 8.1 installations.
I am running the 355.60 Driver on all rigs and i am using the 61 build due to best performance for me with that one.
Anyone have a clue what could be the problem ?
Can i find logs from ccminer somewhere ?
Start swapping hardware one component at a time between a good rig and a bad rig until the good rig goes bad and the bad rig goes good. Then you've identified the faulty component. Some more info would be helpfull. Is there any error message when ccminer crashes? Can mining be resumed or does the system need a reboot? Here's something that can be added to a bat file to check for a crash. tasklist /FI "IMAGENAME eq ccminer.exe" 2>NUL | find /I /N "%1">NUL if "%ERRORLEVEL%" NEQ "0" goto restart_ccminer_becauuse_it_died I will take a screenshot next time ccminer stop mining, cant remember what it say when it happends. If i just close the miner and start it up again i will get really bad hashrate. So a reboot is needed after every "crash" I have been testing replacing some hardware like psu and ram but still the same problems with these two rigs. I am starting to think that these gpu:s are someway faulty. All these three cards are used cards that i have been buying lately. I would suggest swapping the graphics card to check if it makes any different. And I have been mining with release 66, so far is stable for me. |

On my Win10 system, MSI Afterburner has memory leaking issue. After 2 weeks of continuous run in the background, it ate up about 1.7GB of RAM and refused to launch, throwing out "Out of memory" error. So I have to kill it and relaunch it once every 2 weeks.
uninstall win10. mining with win10 isn't a good idea performance are lower I upgraded from Win8.1, didn't feel the hit in performance yet.  it doesn't really matter if you have 750ti, it however starts to matter with the 980 I'm running 980. How much do I lose?  depending on the algo, you might lose up to 25% Wow :oo I'm running quark and got 18MH/s++ at 150W TDP. Before the upgrade, I was getting less than that, but sp has improved the algo along the way, so not a direct comparison. |

Looking pretty much on par now, much better. Thanks.
But still slower than release 57.. My gtx 960 only get a hashrate of 9.7 on the default clocks.. I'll send you my command line PM a little later when I go back out to the shop, give it a try and see what you come up with. Mine is on stock clocks as well, but its a EVGA SSC card. @--scryptr I have fan speed manual change enabled in Linux Mint 17 for my 660Ti, I'll also look at how I got it working and post that for you as well. I have replied your earlier PM... |

Just done some comparison for GTX970 on quark algo. Release 61 is faster by roughly 200kH/s compared to release 57 and 58.
So probably only GTX960 is affected?

Maybe possible to add a specific card option switch? Or released a different optimization binary for different card? If it's too much development effort, then forget about it  |

I have been thinking why is that 64-bit binary hashing slower than 32-bit binary.
Tried to tweak around the CUDA C/C++ configuration properties but still having hard time to catch up with 32-bit binary - trailing 200kH/s.

I have ordered a gtx 950 and a gtx 980ti now. ROI in 1 year with the current prices  This meens that I can test and tweak my mod on almost all the available cards. gtx 750 gtx 750ti gtx 950 gtx 960 gtx 970 gtx 980 gtx 980ti You almost have the whole Maxwell family!! What about Titan X? LoL |

I have only added 500KHASH on the 980 (sp-mod 61-git) Which algos did you rewrite? And will you make it public?
rewrote lyra2 code:  Good job. I guess the new kernal is using more power? yes, the 980 runs at 110% tpd and the 750ti close to 95% (on my gainward stock). Honestly I will try to backport (if possible... not entirely obvious though, the new kernel relies on warp shuffle technique) some of the change to amd before releasing it, I don't want to create more imbalance... Will it be available for public? Donation will follow |

+150kh/s on 750ti +3MH/s on 980 Which algo? On latest sp_'s github?  lyra2rev2, not released yet... Eagerly waiting |

I have corrected the hashrate bug in quark. and build a new exe. The version number is still 61
Do I have to compile it my own or grab the exe from the github's latest release? If you are running Windows, you can download the new zip package under the releases tab. He built the executable file, and reposted Release dot 61. --scryptr Thanks, trying it out now |
