CCminer(SP-MOD) Modded GPU kernels.

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.

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

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.

intensity problem?

intensity problem?

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

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.

Same GPU? How are your temps?

[Longsnowsm]

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.

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

[Longsnowsm]

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.

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

[sp_]

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.

[sp_]

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

You mean to mine Decred at CPU ?

[dominuspro]

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

Give us some numbers please.

[Velgelm]

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

why still private, wasn't going to be public this dual miners? not fair, clymore released it public with a very tiny fee

Not sure what this is about... Did you realize that you can now earn a extra $1.5 a day per GPU and decided you didn't want to share? You already said you had a prototype up and running weeks ago.

Claymore is already doing this... there is a ton of people using his miner. It's not going to wreck the market that much worse then already happened, especially if you get 1% of all Eth mined and 1% of all Dcr mined with it, it should be infinitely worth it.

I've tried this already, it lead to a lot of GPU tossing back and forth between the two miners.

I already own your decred miner.

Which algo or coin profiatable with 750ti's .Still anybody use 750 ti's?i have 15 of them and soon i'll switch off cus of low profitable.

[restless]

750Ti are still good cards for everything excep ethereum. afaik

[fenomenhaa]

750Ti are still good cards for everything excep ethereum. afaik

Ethereum is the most profotiable coin right now.(so far from others).so this makes this cards not so good for mining.

[Amph]

750Ti are still good cards for everything excep ethereum. afaik

which is bad, because ethereum right now is skyrocketing again, making it the best profitable coin, by a long shot

[Genoil]

Despite the TLB issues, they're still more or less useful on Linux at about 4MH/s (from what I've been reading). That is not extremely bad at only 40W. You just need a relatively high amount of mobo's, CPU's and RAM to drive a lot of them.
