Keep rebooting windows, at some point it usually finds all cards. If it sees 960 it should find 750 too.
Are you sure your pcie settings in bios are what they should be? Usually you need to do some tweaking there when running more than two GPU.
Which leads to my question... someone here running skylake (Z170) based mining rig with more than two nvidia cards? How did you do it? Spent 12 hours last night trying to figure it out...

I have a motherboard that has five PCI slots (two PCI's are the small version). It didn't like four 750 Ti's, but was fine with three 750 Ti's and 960. Do you think this is a Windows thing out of curiosity?
Did you plug in all cards in at the same time ? When using windows i always start installing the cards in the pci-e port nearest the cpu. And then adding more cards one by one as long as they get detected by windows. Sometimes it can be a real hazzle before windows find all cards, i even have to move cards around on the pci-e ports to get all cards going. So, plugging all four cards in there and installing the graphics driver will probably not work right away. Make sure you use a powered riser in the x1 slot if the 750ti doesn't have an external power connector. |

22 for 5.0+ cards across the board and 19.5 for older cards if I'm not mistaken: uint32_t intensity = (device_sm[device_map[thr_id]] > 500) ? 256 * 256 * 22 : 256 * 128 * 39;
It'd be nice though if ccminer would show the instensity upon launch even if the -i parameter isn't used. |
Not your keys, not your coins!

Make sure you use a powered riser in the x1 slot if the 750ti doesn't have an external power connector. this is all good advice for troubleshooting windows based issues ... if you try your hand at linux - let me know ... it has almost no issues recognizing cards - but the drawback is you dont have the flexibility for overclocking that you do with windows ... but then again - linux is free too ... no matter how many machines or how many times you install ...  ... i use fedora 22 x64 with cuda 7.5 ... compiling ccminer-spmod is a breeze in linux and is reporting the same ( and sometimes better ) hashrates than cuda 6.5 ... if windows is still your base - then a lot of veterans here can help ( and have already answered this question ) ... #crysx |

Thanks for the info- displaying the default intensity would be great thats if you use the -i parameter ... i use the -X parameter and that seems to push a little more for some reason ... sp could probably explain that ... on the gigabyte 750ti oc lp cards - the parameter is -X 29 here without overclock ... #crysx |

There are so many around it's a very though question to answer. Let's say most of the popular coins are supported, except for example scrypt-Jane ones. |

does anyone have a good launch configuration or intensity setting for plain Scrypt algo for the 750ti? I use a config file to launch ccminer and neither "launch-config" nor "intensity" seem to be doing anything.
the cards always default to auto-tune, it always sets to T30x16 and i get "result does not validate on CPU" errors.

If memory serves me right, -l T5x24 is what you're looking for. Good chance I don't remember this properly though, you know, old fart and all  |

 Top rig just prepared for some 980:s that hopefully arrive tomorrow. Notice the single 750Ti left alone in the second frame. That card only run without problems when mining single in a frame. If i run other cards in the same frame it will make the rig shutdown like 3-4 times every day. Something is really strange with that card. I have spent many hours trying to figure out what the heck was going on before i sorted that card out. When the replacement fans arrive for it i will sell it. Right now my plan is to fill up the top frame and the second frame with 980 cards and then put two more 750Ti:s in the third one. Not sure why the hell i am doing it when the earnings is like crap, but someone need to go full retard i guess. Sorry for offtopic. |

Well since my great antec hcp-1300 died and it has a 7 year warranty I get a replacement free? Not. Antec's great rma services..it may be a month before I get a new one free oooo I have to pay for shipping on there free replacement. There process of getting a rma is fantastic ... 2 hrs before someone answers the phone that's great. And if I speed up the process they want a downpayment of twice what I paid for it. Yes ANTEC is a great company with fantastic service.
