[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX] - page 384.

I've mined before but with 280x and i've seen that with 750 Ti on X11 algo reach 2,1-2,2 Mhrate but i don't know how to configure ccminer or bat file

Thanks it;s working 1,9-2 Mh rate can u help me with O.C settings

BTW, if you OC to much you'll notice that ccminer goes nuts with high hash rates (off the chart high), will crash or you'll see strange errors. Just back off a bit.
Hope this helps,

Does anyone know the fix again for this problem. My multicard rig like clockwork will go nuts with highhashrates after some time. This is running stock clocks. At the minimum is there a ccminer command that can restart it every 2 hours or so? I can't find the page that discussed this solution.

How many GPU's and what OS?

Windows 8.1, AMD A6, 8gb Ram, usb powered risers. (usb risers are plugged into 4pin molex because i'm not sure if they work without being plugged in).

-I know it happens with 4 or 5 cards in the rigs (haven't reduced the cards to 1 or 2 to see if they can hash stable). Happens on both a 500watt corsair and 600watt corsair rig. Used both the last 2 latest Nvidia drivers, no change.

The other thing that happens and others have noticed as well is that 1 or more of the 750ti's will downclock to a very low clock speed. The 2 symptoms are probably related.

I thought there was some programming fix for this but it's lost in the thread.
EDIT: I've studied it and essentially one of the cards is crapping out or dropping the driver and the makes the card drop to 500mhz clock. This then causes all the other cards to lose stratum and the hashing goes wild for all the other cards. The card downclocking is the number 1 card position in EVGA precision. Does that mean it is in the first riser spot or the last x16 PCIe slot?

What you can try (no guarantee it will work) is to set the parameter SHARED in some .cu file to 0
(I know this solved temporarily some problems I had with my gtx780ti, however I just had to decrease the overclock as my problem was caused by excessive overclocking and the symptoms were different (loss of power then driver crash))

You might have mentioned this but make sure you do not plug more than 2 cards into the daisy chain. Those things aren't supposed to carry that much current in them.

I have absolutely no problem running 5 on a 550 watt power supply.

Actually...i prefer ccminer v1.0 without the simd improvemend, when i'm sitting on my pc i want to be usable while i'm mining.

Anyone have suggested settings for a 750 TI with the change to N-factor 15 on YAC?

Have you guys checked this?

It would be nice to have such feature on ccminer... Wink

Get a new powerful power supply, it isn't enough. Problem solved. Wink

They need more Amps, juice.

Try this
https://github.com/KBomba/ccminer-KBomba/releases

This is the version I'm presently running on my 3 nvidia rigs.

EDIT 2: Removing the 1st x1 usb riser card along with removing the last x16 onboard card and going down to 3 cards seems to not recreate the problem. If there is anyone who has 4, 5 or even 6 750ti cards stable using ccminer on X11 can you please tell me your entire setup and config? Thanks.
