Decred#8, Decred#9 -C not working
unknown option -- C
Try `ccminer --help' for more information.

Give us some numbers please.

You mean to mine Decred at CPU ?

But you could buy my decred private and run with -i 24 -C at the same time as you run the etherum miner. Works pretty good

There will be no dual miner. I respect the opensource work of genoil @ co, and I don't have time to rewrite from scratch. But my farm is out of riser cables again, and I will be going private and retire.

cheers.

Whats the status on the dual miner SP? You said like another week like two weeks ago...

I am mining Neoscrypt at the moment.  I kept turning down the intensity last night and this morning and now looks like the rig has been up for about 5 hours and hasn't died yet.  So fingers crossed it will make it through the day.  Then if it looks like it is finally stable then I will look at a mild OC on these 750ti's to improve the hash rate and see if that is stable.  Then it will be time to talk to SP about getting a copy of the private release...  Baby steps! :-)

Just glad it is starting to behave a little better.  Hopefully it will stay solid for the rest of the day.  I am mining on zpool at the moment.

Which algo? It's expected for most of the X1* algo series.

Same GPU's, temps are hovering around 60c, still all stock speed settings(ie no OC).  I have been just trying some of the suggestions in this thread for cpu affinity, cpu priority, and now I am playing with the intensity settings to see if that helps.  The affinity, and priority didn't help.

Same GPU? How are your temps?

Thanks for the input and suggestions.  Well after a ton of trial and error, loading drivers, and updates I think the rig is starting to act somewhat stable and I was able to get the GPU up and running, then added one at a time.  Finally have all 6 gpu's connected.  Looks like a good portion of the issues stemmed from ASrock drivers issues for this mobo.  The included drivers were junk, and the software/online updater fails.  So I found the downloads and installed them individually and I think I have everything updated now.  Now with the drivers and Windblows updates done it is acting more like it should.

Now the issue that is appearing is that when running CCminer it will run for a while.  Sometimes for quite a while and then suddenly it will start screaming:

GPU #X result for nonce $00000000 does not validate on CPU!  

Then it will run away and then CCminer will crash.  I have restarted this multiple times now and the same behavior keeps coming back.  Any input on why this may be happening?  Thanks again.

Different symptoms AFAIK. Too high intensity usually causes the miner to error out, not the driver to crash.

intensity problem?

I think he's trying to get one card working.

I think it's a HW problem, GPU or MB, maybe power but unlikely with only one midrange GPU.
Maybe a bad PCIe connection, are you using a riser? powered? Maybe a bad slot, try another slot.
Swapping GPUs should nail it.

How many GPUs do you have and what's your power supply model?

Thanks for the replies on this. Everything was on stock settings as I hadn't had a chance to try and tweak anything.  So I rebooted the box a couple more times and tried to watch MSI Afterburner to see if I could figure out what was happening.  Sure enough when I tried to start ccminer the power, and temp shot to the moon and then crashed the video driver.   Not sure why since it was still at the 1060 core speed and 1350 mem speed.  So I cranked it down to like 600mhz on the core and turned down the power to 80%.  I then started the miner and it would start and run at like 40khs.  I slowly put things back to the stock setting in MSI AB.  However the speeds did not increase from the card.  I noticed on the runs where it was crashing the speed was about 200khs before it crashed.  

So now when I try to adjust the speed up in MSI AB it still does not increase the mining speed.  So I don't know if I need to unlock these cards or if there is some trick to getting any speed from them.  I am still baffled why it would behave this way out of the box and act like it was being super OC'd and crash.  Now I can't seem to get it to pick the speed back up.  

Thougths? I checked the physical and virtual memory and both are at 16gb so it appears it should have enough swap.  Thanks again for the feedback.

Update: I just told MSI AB to reset, then I rebooted, and then tried to start ccminer and it appeared to overload the gpu again and just quit.  I did see the has rate increase to 140-160khs just before it hung.  So Windblows is updating right now, then I will try a different card to see if the same thing happens.

OCing too much, poor power delivery, crappy risers.

You should increase the swapfile to something like 8GB for a 750 Ti rig or 16GB for higher end cards.

The only time I've seen a driver crash is when I OC too much. I presume you tried a different card.

Well the weather is nasty outside today so I have been trying to get this Nvidia rig up and running.  I just cobbled together the basics, downloaded the Nvidia drivers, and the free copy of sp_ ccminer.  I only have one gpu connected to the mobo at the moment and wanted to see if it would at least run before I connect up the other 5 gpu's.  I start ccminer and it runs for about 10 seconds and then the nvidia driver crashes.  What is the preferred nvidia driver version to be running with these cards using ccminer?  This rig is Windows 7, i3 Haswell cpu, 16gb ram, 128gb ssd, and 6 ea 750ti's with 4gb ram. Any tips to get this rig up and running would be greatly appreciated. I am connecting to zpool.ca and attempting to mine neoscrypt.  Am I just missing some switches or configuration to make this work?  This is the first time trying to run ccminer. Thanks.

Added: I downloaded the 1.5.80, but now wonder if I should be running the 1.5.74 instead.  My nvidia driver version is 365.19.
