I Should have name this thread  MY Nvidia GPU Mining Problems, but any problem related to this is welcome in.
My apologies to everyone helping me especially crackfoo for messing up his thread.
I have so many other personal  problems hitting me at the same time.
I started this thread on this extremely annoying problem I have been have for some time with my one rig.
Thank you all for your understanding.
Thank you all for helping out.

Thank you all for responding  :) Do to things beyond my control I may not be able to try fixes right away.. it may take time.

A crash report says an app blocked ccminer from working and has been blocked from accessing the graphics driver. This is the main issue right now.




Starting up everything good.

hi

what do you need ?  :)

When you're ready to dig into this post your rig configs for reference. You'll need to follow a precise process
to avoid confusion. Make sure you can identify each component if they look too similar. Keep good notes.
Limit the number of variables that need to be controlled. Avoid assumptions and prove conclusions.

The first step is to test all your HW. Minimal configs are best for this, one GPU, one riser.
Test them one at a time to ensure they are all ok. If you have 2 rigs test all cards in both rigs to increase your confidence.

Once you've tried them all focus on any failures. Look for pattenrs, if there is a persistent fault the faulty component
should become obvious as it moves and the problem follows it. If it's intermittent it gets trickier.

That's enough to start.

To add to the above post, make sure all of your system is stock clock. CPU and GPU's.  even a minor instability in either can cause havok in a mining rig.

Thank you all for responding... plz read OP as of now I will be adding specs ect updating

Right now it is room temperature. It seems to be so much more stable. Today it will go up to and beyond 32c. At that point it won't mine for more then a few minutes but it should and was 4 days straight without a crash one time about a week ago.
I'm mining muti algo switching with Minercontrol.
And right now everything is fine but as the temperature rises it should start crashing.
I will be doing things as suggested as soon as possible.

Thank you joblo

Thank you.... it is on OP  :)

Yes I turned all oc'ing off.  Thank you

Keep notes of what algos fail to start to see if it's algo specific. Also try to characterize the failures in more detail.
Does it ever fail on the first algo or does it switch a few times before it fails? Once you have a failure does it then
fail consistently. How does it recover, do you reboot?

since minercontrol is being used to launch the apps, have you tried running MC under administrator elevation to see if it helps?

It's a strange problem.... I can't think of what would cause HAL to not let your app access the video card...  The only time I had a problem with miner apps not accessing the video card myself was when there was a driver updated by windows automatically and it wasn't the nvidia package with CUDA updates.

Joblo is spot on;  test all hardware one at a time.  I know it seems annoying and it takes a lot of time, but you will find out where your issue resides.  If it is on a specific algo;  try trimming the intensity back a touch, at least .5 if not 1 from what its at currently.  Since Temp is an issue, I would consider this for sure.

I know you definitely need the individual driver packages for each model of card you are running to be installed.    In the past I have heard of people running into bugs and issues when they are mixing and matching types/generations of cards, and they were always able to resolve by having each card type on a separate rig.  This way drivers are unified and the system OS is simpler.

No real specific algo..... I have to reboot.....  it doesn't fail on first algo meaning it will mine that algo for a few minutes then crash..but when temperatures rise. Right now it is room temp and running fine through the algo's as it gets hotter it should start crashing.

Yes I did try MC under administrative. And it crashed within 3 minutes .. but running at 32c in the room  .. right now it is very cool in the room..room temp 1 degree less and running great.
I think we can start looking at msi afterburner maybe for the problem .. not sure. Maybe the app fan control ? Not sure yet.
Thx

In 6 hours it should start crashing as the temperatures rise.. summer here and a heat wave.

Ok first crash 5 hours later at 25c.

Just to be clear, does it always start mining then crash due to access blocked or does it ever crash on ccminer startup?
Does it crash if you run a single algo without ever swicthing?
Have you been monitoring GPU temps?

It starts mining like normal..then crashes after about 3 to 5 minutes after mining.
Rebooting it now.

Worked for 3 minutes then crash.... apparently algo's don't matter.
This is before crash....rebooting again turning box fan up to full to help cool.


https://i.imgur.com/OhxEGMn.jpg

why you still have 3 different card in the same rig, do you really need the 750? not saying that that is the problem(well it might be) but i find it wacky

Ok mining fine then as it went to switch algo's it went through it's cool down cycle I have set to 12 seconds ...needed to get from p2 state to p8 state ..then crashed.
Now I have at the wall watt meter and during this stage it should go down to 92 watts but didn't.. it went to 252 watts not mining  humm.
Going to up that time to 20 and give that a try.
This is not the crash that was happening.
The display driver never works after that need a reboot.

https://i.imgur.com/3UtB4cs.jpg

The 750ti is fine amph  need all the hash I can get... thx
If we get this fixed then I'll add the other 970 gtx sitting in its box.

There are 2 maybe 3 things making it crash.....I think I got one of them.... proving by upping the cool down time.

Now 970 gtx is not recognized and sometimes the 980ti too on fast reboot.. need to reboot twice to be recognized.
This doesn't happen at lower temp if it is related to temp.  room temp  83 f  28c .
On that crash wattage went down to normal 92 f to change algo's.

That will happen no matter what ccminer im using.
83 f  28c temp room.
Second cause of crash.
Got it captured finally. 970gtx card 2 device 2.
That cards clocks default mining p2 state 1413 should be 1117.
Now my 2nd 970gtx when I tried it.... clocks the same thing so I did an rma an that ....so when I got the rma 3rd card 970gtx the clocks the same thing 1413.
Their supposed to be about 1178 core but always show 1413 core no oc'ing.

You're juggling too many things at once, start isolating cards. If you have multiple faults you have to seperate them.

You seem to have an issue triggerred by heat, you need to find out which card it is and you need to monitor
the GPU temperatures to confirm it's temp related.

That's what I was doing... now im mining one algo only and so far no crashes. :)
Room temp 86 f.
I'm also posting extra info for my own notes.
Thx joblo for your help.... much appreciated.  :)

OK, so your following the algo switching lead. Following up with that, has it failed imediately after a reboot,
ie the first algo starts up but crashes after a few minutes? Or does it run fine for a while algo switching and not
crashing until suddenly it crashes? Monitor the GPU temperatures, not the room remperatures, to see if there
is a correlation.

You will also need to identify which card is crashing. If you don't want to test one card at a time you can test minus 1
card at a time, remove one card, test, resinstall, remove a different card, repeat.

i would recommend to install linux.. try with a separate hard drive as you are bound to have problems the first time.. but there are guides on installing the driers, cuda and all that.. my linux rigs run for months without crashing

apart from that you can try booting in safe mode, i had a 6x750ti rig running windows7 that would (surprisingly) mine in safe mode without any issues. otherwise it would crash every few hours for different reasons.  however in other rigs using windows 2012 hashing in safe mode does not work

Yes exactly.... it crashed... card #2 again   970 gtx   now going to mine without it in the bat file on lyra2v2 only no switching. But the crash .....it was mining with only the 970 and scrolling fast but mining.
I have a lot of things that must get done... so I will be on and off the thread for the next day or 2. :-\
If it still crashes I will remove the card and try that next. :)
Thx

Thx DrkLvr ... some time in the future I may do that.. thx

I'm wondering if it is a heat issue.  Can you run a temp monitoring program and observe the temperatures up to and during a crash?  Try also not using miner control and just mine one select coin and see if you can make 12 hours.  One card at a time, repeat process.  If you're using a scrypt like JK's, then you aren't the only one getting crashes every 6 hours(mine does as well on 1.03).   My theory on the scrypt switching is it fails to close the non profitable miner before opening up the other, and with high intensities(which is another issue you might be running into(if you're mining with -i intensity try removing that altogether))it causes a memory overlap and crash.

I'm running lyra2v2 right now without the 970 gtx in the bat file. Running great. Take a look on the OP.
The 970 gtx is at 1413 core clock.. should be 1178..I think that is one of the problems.
I'm just running the 2 980ti and 1 750ti test run.

https://i.imgur.com/wpQg90s.jpg

This is not good hashing, that card is sick.

If the 970 is not mining, why is it so hot?

38 degrees is something you would see under water at idle.  Unless you're getting valid hash messages (yay!, Yes!)  your card isn't doing what it is supposed to be doing.  Your card can be overclocking itself due to boost clocking.  If the card is spitting out numbers faster than you can see them scroll you're producing nothing but errors and garbage.  Perhaps you have a corrupt version of ccminer or cudaminer?  Try getting the newest 1.8 or redownloading it,  My cards under load hit 58 degrees and thats under water with 7 120sx radiators with an ambient temperature of 24 degrees.  75 to 80 degrees under load for air cooling would be as high as I would push your cards.  Since you're using msi afterburner, you can tune each card individually to stock settings if you like.  I have seen issues with shady power supplies not providing enough voltage to cards, as well as motherboards that don't like 3 cards on the same motherboard.  I know its frustrating, but my suggestion is to start with the lowest videocard.  Take every other card out, and get that one stable.  Then repeat for the other cards one at a time.  We are checking to see if your cards are bad.  If the cards are the same, you can put them together after verifying that they work individually.  And double check to make sure SLI isn't enabled by accident.  That will pock up mining.  I found that one out the hard way.

You could also try updating your nvidia drivers.  you're a few revisions behind.

It's in a room.. temp 95 f 35 c  and next to the other cards..
At room temp that card mines very cool about 68c on some algo's.
If I run the other 970 gtx I have all by itself all cards removed .. it will crash immediately.
I think I have a bad batch of 970 gtx cards.

That is after it crashed the drivers. Scrolling. 

I haven't been following this thread but if my afterburner panel would look like that I would first go to fan tab.

And then sell those 750ti's. I sold after 500 days of mining thinking that aftermarket price would tank. I was wrong.

After it crashes your cards are just producing errors.  It may seem silly but try stress testing your individual cards with furmark.  If the cards themselves are bad, they should produce artifacts.  Plus you can monitor the temperatures.  there is a bootable usb linux for mining called KopiemTu that you could try as well. It isn't as user friendly but if you can get it mining then that eliminates the operating system.

Which temp is for which card? It looks like the third card is at 79, isn't that ccminer GPU #2?
Anyway if the cards crash at stock settings and reasonable temps they are defective.
Double faults can easilly get you going in circles trying to troubleshoot.

Doing good.

3rd card is a 980ti 79c is what i set as max going to lower it.

Not sure if this will help you at all but I was having a issue similar.

I had  one 970, two 960 and one 750ti in a rig and I had one card that would always crash while mining certain algos. It was always the same 960 and sometimes a few minutes and sometimes a few hours.

I used Nvidia Inspector to determine this as it always showed the same card with the fan down to 0% after the crash. I tried new risers (powered usb) and the same thing. I was starting to think I had a bad card so I switched the 960's only in each riser to narrow it down. Low and behold the card that was having no issues started crashing and the card that was crashing would not anymore. Same thing after switching and same algos. The card that was crashing would not at all any more.

I was perplexed. ran out of ideas and I had one last thought. I just switched the riser connector on the mother board that was crashing with my 750ti pci-e slots. I looked in Nvidia Inspector and noticed my 960 that was crashing had switched PCI Interface numbers. Both 960 cards read 3.0@1.1x1 before the switch and after the card that was crashing read 3.0@2.0x1. Now it reads the same as my 750ti. So both 960's read different values and I have not had a single issue since.

I am no expert and have no idea why it fixed it but it did.

Hope that might help and hope it made sense.

I'm just guessing but it look like the notation means <slot version>@<running version><lanes>. That would mean the slots
were running at PCIe v1.1 even though the slots and cards support v3. I have no idea why swapping slots would change that.
Glad you got it fixed.

Still doing great on lyra2v2 stright mining almost 20 hours. Next is to do Minercontrol without the 970 in the confg file.
Do to things I must attend to.. I may not be able to post until Thursday.
Thx

Thank you antonio8.
Glad you found your problem. :)
I have done the switching but I need to look into it in detail.
But I have had 3 970, I think all from the same batch or lot, and all were not mining in the p2 state at 1178 core. They were at about 1423 core clocks. Going to call gigabyte again asap.
Will look into switching slots again.
It's as if they where oc'd without oc'ing them.
Thx

A note  7-21-2016
My rig mined all day with all cards with MC. :)
Room temp 92f  humidity 35%
For the four days before that the rig crashed at only 87f humidity 85%
Possibility the humidity played some role in the crashing on with the 970gtx that mines in p2 clocks default 1413 core.
Maybe micro dust.
This weeks temp are supposed to be record breaking 100f......... humidity.?    
Slowly one thing at a time to pin down the 3 things contributing to the crashing.
Due to heat I will have to shut down the rig for sometime during the day for the next 5 days.

EDIT:7-22-16 rig mined all day today with MC room temp max 95f hum 45% the only change I did was turn off oc'ing and set  "delay": 15  to "delay": 30.
So one problem is heat related cards changing algo's going from the p2 state to p8 state in order to mine or some call it spin down time.
The hotter it is the longer it takes for spin down.

https://bitcointalk.org/index.php?topic=1260863.msg15551454#msg15551454 (https://bitcointalk.org/index.php?topic=1260863.msg15551454#msg15551454)

Thx JK I have done this.   Will that keep them in the p0 state on reboot?
EDIT: I'm going to give this a try again asap. thx

Interesting observation. I never really considered that it would be more susceptible to crash when switching algos, or that
spin down time could mitigate.  Good to see you're making progress with your "heat chamber" testing.

so damn...
great idea. this is what I want first but until now they have not found a good example
my gpu need big upgrade for this :-\

No.. this will have to have admin rights first deactivated (check zpool thread for command) then reboot, and it shouldn't need admin rights anymore.

then add the path to the NVSMI folder to the system PATH and you can just call it from any old command prompt/provision allotment =)

Issue the memory and clock set command every reboot, or better right before the miner app launches.

Thx joblo  yes still in a severe heat wave..never seen this before. One day I turned off the miners until the evening. Today same thing I think 100f  :-\

EDIT: I do have the temperatures of the cards set at a max.. to not exceed 79c ect.
And I use to get this  but was going to talk about it later.
Going to myr-gr  also on neoscrypt  so not related to algo but memory or ccminer? Maybe intensity setting.
https://i.imgur.com/HWmmLME.jpg

Thx JaredKaragen  looking into it. And where is that command plz on keeping the rig in the administrative mode on reboot. Thx

And where is that command plz on keeping the rig in the administrative mode on reboot. Thx

"c:\progra~1\nvidia\NVSMI\nvidia-smi.exe -acp UNRESTRICTED" removes the admin requirements.....  Run as administrator in command prompt.

I havent tried rebooting to see if this needs repeated on boot.   if so, it will need to be automated at boot-up somehow.

But one p-state issue ive tracked to the neoscrypt algo.   Try removing it for a time and see how much it helps.

Thx JK see my post on zpool plz.
https://bitcointalk.org/index.php?topic=1260863.msg15712991#msg15712991

But I still may give this a try.  :)

Looks like a null pointer dereference. That's usually software but in your case it could be excess heat in the CPU or RAM.
How is the ventilation around the mobo? Maybe heat from the GPUs is destabilizing the CPU.

Edit: It could also be bad RAM. Make note if they are always the same, especially the instruction address.

Try a different power supply.

You'd be amazed how many are bad and have you point the finger somewhere else.

Thx  That is my 2nd psu and i have a third to sli for my extra 970 but it is hard for windows to recognize it and it crashes within 3 minutes. So since I made some changes I will try again soon.
I have a fan at high speed on the rig.
This only comes up once in a great while.

It could be a bug in ccminer for neoscrypt lyra2v2 ect. not sure.
A fan at high speed but the temperatures were so high, room temp, that I turned off the rig at 1pm to 7pm some times...cooler temp on its way.
There's not much I can do until temps drop... it broke records.

If it was a bug others would likely also see it, but AFAIK no one else has seen this crash. You're getting corruption in the CPU domain
(core, cache, ram), either due to a HW fault or heat induced. If there is a pattern to the fault addresses it's probably a HW fault.
If the're random, probably heat induced.

Due to the extremely high ambient temperature your sensors may not detect overheating in places where it isn't expected.

What is AFAIK? joblo  and when that neoscrypt or lyra2v2 that it crashes on once in a great while showing this sign, some people have reported that I think... but also happens at room temp too. There maybe to many cards for windows memory to handle. But will look into what you said.
Someone did say they were having problems with those private releases.
Thx

http://www.urbandictionary.com/define.php?term=afaik

This the first time you posted this symptom, has it always crashed this way?
If you think it's the miner try a different one.

AFAIK=as far as I know

If its a temperature problem, theres a system level component that's having an issue I would think.

Run a motherboard monitor and CPU monitor.... but a voltage issue could still be the case.   I hope you are figuring your power availability per rig @ 120-160% expected draw?  If I ran a 4 card machine I would be for sure running a 1600w power supply..... 

I wonder if you are drawing too much +12V off the same rail that supplies the processor and are causing this all to happen.

I have seen many strange configurations once opening up power supplies and seeing what is tapping which available rail.  Many PC power supplies have 3-4 independent +12V power supply circuits at roughly 50A each...  give or take....    As far as knowing how they are distributed...... you have to open the power supply often to know the real truth...   

You dont happen to be CPU mining at the same time are you?

Thx This happens once every  2 weeks unpredictable and I think it maybe the app ccminer not sure.
I just wanted to post that as one of the secondary issues for now.
Right now I'm mining a straight algo and no crashes at all... very very smooth at 93f room temp.

I dont really agree with the above (per-se):

1) I agree with giving about 20% headroom, but a 1600W PSU for 4 cards isnt necesary (unless they are 290/390 cards or some other varient that would be drawing 300w/card). the rx480 or gtx1070 you could run 6 cards with a 1200-1300W PSU just fine.

2) most quality power supplies have a single 12V rail, and the ones wit multiple rails normally are more like 2-3 rails at 30A each (3x30Ax12V=1080W)  Your suggested 3x50Ax12V PSU would be a 1800W+ beast

3) you DONT need to (or want to) open up your PSU and start poking around. youll void the warranty, risk damage, and waste your time. any half-decent power suply will have the power rating and rail ratings marked on it and also on its packaging. If not, use google.

pretty much any PSU that is gold-rated and costs >$100 should be a single 12V rail thats rated at about 95% of the actual PSU specification.

for example, the corsair ax1200 has 1202W on a single 12V rail: http://www.corsair.com/en/professional-series-gold-ax1200-80-plus-gold-certified-fully-modular-power-supply  (click on the technical specs tab)

Yes I did have that issue ... I can't add another card 970 without sli the 2 psu's 1300 watt each.
I did try taking 1 980ti off that rail and add it to the 2nd psu along with the 970.
It crashed ... but I should try the new 970 all by itself. That maybe a bad card.. not sure..I did a rma on it and it also crashed.
I think the main problem is the asrock btc 81 pro cant handle that many high end cards running windows 8.1.
And the 2nd most thing was temp spin down time changing algo's which is fixed. I think.

oooo on the overloaded rail... yes I did...now fixed.
That was when the psu was shutting off.
No cpu mining at all I have to use    --cpu-affinity 1 --cpu-priority 0

When the psu was shutting off I was trying to draw 1085 watts on a continuous 1300 psu which really equals 1200 available.

Yep;  that's what I was thinking.   When you start drawing too much, internal voltage drops and amperage turns up.  This causes more heat in the components and a snowball effect ensues.

My comment about several 50A rails was literal, and is a pretty close and very realistic situation.  When I give these values, i'm not joking.... They are coming from my Coolmax 1600w.    I know the math says there's ~1920W of just 12v power available (E/I*R) cause the sticker says 110A and 50A of 12V power:  But the sticker, shows that its only allowing 1600W total from the PSU; with a max of this, and a max of that on each designated supply line (12V#1 and 12V#2 are stickered to be a max draw of 1560W even though the math of E/I*R says more).  

I have seen a few people burn down S7's and S7 power supplies because the the two sets of PCIE plug rails were only capable of 110A total when they were under the appearance of being both separate circuits;  Yet the power supply said there was another ~40A of overhead. (1560W of 12V between the two is available total if you trust whats on the sticker)... This is not an 1800W power supply;  but it allows for a total of 1600W to be drawn from it across all voltages in a combination which allows a massive; nearly 1600w of +12V usage in theory.  The problem is 12v rail 1 only supplies PCIE (110A), and 12v rail 2 only supplies the motherboard plug, CPU plugs, and accessories such as SATA power and the like. You would never know this is true unless you took it apart.  One of my coolmax PSU's are from a person that burned down an S7 drawing too much from it.   I had to open it up, and hack-job-rewire the modular plugs in the back of the PSU to bypass and cut out the old melted PCIE cable plugs and fix the remaining good ones to have a good usable PSU again.   I will also rig up some PCIE plug adaptors to utilize the FDD/HDD power ports, and the motherboard connectors as well.

To finish:
You not only have to obey the sticker, but you have to use a little extra sense when trying to figure it all out.    Don't ever assume any one thing is correct unless its totally verified ;)

Yes exactly.
I even called antec about that and they said they did a test run with 3 980ti and of course supplying power to the mb ect. is the max. 12 at 50amp rail is for 1 980ti only no more. They say they have it down as drawing 39amp. Even though it doesn't.
But now the problems as far as psu have been solved having 2 of them sli. :)
But at the moment they are not sli.
And the extra 970gtx is still in the box.
ps Been running an algo for days now no crashes no oc'ing ..if I do oc ....crash.
Since 2 problems maybe out of the way out of maybe 6 problems I may try again sli psu and put the other 970 doing this same algo  no oc. If that mines stable then on to test the other problems.
Thx  JK

Glad to help.

Ive noticed most people reporting issues have been with the middle model cards (970, etc)... so I tend to stay away from them myself.

Its almost as if the 70 model is a batch of high end chips that all the cuda cores didnt work on or something, so they make that die work at a lower rate with less cores and not loose manufactured but failed high end product....

Cant wait to get up to SF and pick up that 960 off the shelf and get it back to work.   We took that duck 960 machine apart to build out a system for a customer and the second video card had been sitting waiting for its new home.   He planned to go 10 series on the next machine, so its not a big deal for him to trade me 2 power supplies for the 1 card.

Just saw this.  Still need to watch, but maybe might be something u want to look at given the title....

Yes I can get money I believe ... have 2 970 ... thx

Ok On my 970's g1 trying now to add the 2nd one.
msi afterburner display wont show the extra 970 but it is recognized on the control panel.
And the clocks mining in the p2 normal state are showing 1400 core clock...so something is overclocking them causing them to crash? Going to delete all monitoring software to see if the clocks go to normal.
Also going to manually set the clocks to 1178 mhz where they are supposed to be if necessary.
Even though the rig has been mining for days now and no crashes without the extra card.
2 days ago I tried the extra card in and clock default to oc'ing 1413 to high.
With the extra card it will mine for 3 minutes exactly then crashes the drivers.
Reboot and mine and 3 minutes drivers crash.
Gigabyte says to download OC GURU and try the other bios non gaming to see if that helps.
Be back asap with the results.

This is what happens sometimes on a fast reboot, it is the 970 1st card 2nd card not installed.
After rebooting a 2nd time this doesn't happen.
I think I need to take fast boot off on my asrock 81 btc pro to normal boot.

This is the first 970 crash below.

This is with 5 cards installed 5th card not recognized by windows.

This is the problem with installing more than one GPU type per system:

You'd have to do a nvidia driver "clean install" for the device's specific driver to fix that issue.....  Which would remove the other versions of the driver for the other cards........

Any chance on getting the 2 970's in their own box by themselves to test this?

Also:   Any special edition cards such as "OC" or "SSC" should never be overclocked.   The manufacturers have already done the legwork for us for the max reliability/stability on their card build.   Keep this well in mind.....   I never overclock a SSC or OC edition card.

probably why the "non-oc" versions can easily match or beat the OC cards wen actually tuned manually. my strix cards (base model) can exceed the specs of the OC version (~8% faster for a $50 premium)

agreed.  my GTX980 is a strix.

I just added a EVGA 960 SSC 2Gb card to my machine that has the Asus GTX 980.  Still solid on lbry, went from 154Mh to 248Mh.   Happy.  Driver install was painless.  Though on the X58 motherboard for some reason I can't use the PCI port when running two video cards.   I may try stacking the cards up (not on the optimal config) in different slots to see if I can get a PCI card to work with both of these video cards.   I use this machine day in and day out and it mines 24/7 weather I play games or not.


Been pretty solid so far.  Lets see how this mix of video cards treats me in the near future.

No  but the driver I use is made for all cards JK.
I think we got the problem down to 2 issues now.
One windows 8.1 can only handle so many high end cards like someone I know tried to put 6 980ti on his rig...it can't be done. He got 5 but with lunix I think.
So if I had that many cards and did windows 8.1 the max maybe 4 cards...but it maybe msi afterburner seeing only 4 cards.
2nd I'm working on right now is the clocks are most definitely wrong on the 970's.
Going to set clocks to 1178 like their suppose to be with 2 970 in the system and see if that works.
If not going to delete all monitor app and try again.

This card      http://www.newegg.com/Product/Product.aspx?Item=N82E16814125684
and something is oc'ing it   an app IDK
So this maybe one of the main problems. Clocks are at 1393 right now. p2 state.

For a reference before I change clocks.

Adding the 2nd 970
Msi afterburner doesn't recognized it on graphics monitor but does on the control panel.

Mining for 2 minutes  then crashes with the 2nd image below.
Now going to set the clocks.

maybe you are pushing just a bit too hard? also whats your cpu/ram combo? I found that running lbry and ethereum side by side (i mixed amd and nvidia cards) can take up a lot of the system resources, including ~3GB of ram.

Thx  but no I'm not pushing the clocks higher ... something else is.
I'm now setting the clocks to normal 1064 for the 980ti's and 1178 for the 970's.
I wonder if ccminer is doing this?

Found out that the 2x  980ti's and the 2x  970's are in gaming mode ... they have dual bios.
I may have to use OC GURU  to get them into over clock mode.
Can someone plz check to see what mode your 970 gtx is in plz.

Ok after setting the clocks to 1178 the 970's mined at 1417mhz core clock still.  :o
Something is setting or alternating  the core clocks.
And the cards are in the gaming mode... going to change them to oc mode.

Here is a post I found on another site and I'm unable to uninstall all the files from oc guru it says one file needs to be updated first before I can uninstall. Is it part of the problem?... maybe..maybe not.
And my cards are in gaming mode.

>Gigabyte's OC Guru Cause Of My Annoyance! Finally after trying all the various fixes I have found the solution to not being able to play the game without it crashing. It turns out it was the Gigabyte OC Guru program running in the background that was conflicting with the game.
After closing this program (which I don't even use anyway!), I was able to get past the intro movie, past the birthing scene and into the main game and play perfectly fine with no crashes at all.

I urge anyone with a Gigabyte graphics card to check if you have the OC Guru program running in the background. Check your hidden icons and look for it there and then close it. Better still, check your startup programs in msconfig and disable it (OS_GURU).

Going back through my posts it was fellow forum-er ajw5105 who first alerted me to the fact that my overclocking software was causing the problem but I think I just skimmed past the message. Thanks to you ajw and also to thefrench author of this thread: http://forums.steamgames.com/forums/...4#post24574174 which explained exactly what to do.

I hope this helps those of you who are still having issues running the game no matter what fixes you try. It could be that you don't have a Gigabyte GPU but a similar piece of software is what's causing the problem.

The next time your game crashes before you just exit it, click on the little dropdown more information arrow and take note of what the Fault Module Name is. It's likely to be a DLL file (in my case it was GvKm.dll) and then Google that filename and see what program it corresponds to. Then either disable that program or uninstall it if you're not using it.

Sorry for the long post but I think there are a lot of people out there who are driving themselves mad trying to get this game to work.<

After installing oc guru and found it didn't have the things needed.. I uninstalled it and run into the problem on my last post above. I then reinstalled it to try to get that last file uninstalled.
Rebooted and took 2 reboots for the extra 970 to be recognized.
Then using msi afterburner I tried mining again. And afterburner only displays 4 cards but controls 5.
The 970 clocks are at 1417mhz but been mining now without a crash for 20 minutes .. first time in 2 months. First time period.
See how long it lasts.
1 hour so far. One algo only too.
EDIT: Wow 12 hours now .. still mining in the p2 state.

nice.

Yeah;  IDK how you ended up with a driver that encompasses all models;  Because I have the 980 driver installed on my machine, but I had to go to nvidia.com to download the nearly 300Mb package to install the 960 driver alongside with my 980 before miners would see it......

I haven't had any crashing issues yet on all stock drivers/settings and the two mixed cards.

I did wonder if I should do drivers for each series card but I didn't need to.

Here you go JK ;)

http://www.nvidia.com/download/driverResults.aspx/105033/en-us

12 hrs and rig still running. :D

im running 10, so that link wont work for me XD

Anyways... I am happy to have my 960 alongside the 980.  It surprised me with the card size difference when seeing them next to each other:

http://i26.photobucket.com/albums/c115/JaredKaragen/Mobile%20Uploads/IMG_3504_zpsdnomoiqw.jpg

The fact that the 960 only takes an 8 pin plug is kind-of nice as well.   I've been hashing solid on LBRY for the past few days.  No OC utilities used.  I might use the EVGA k-boost tool to lock it into P0 settings throughout all P-state changes.... but its been pretty stable as-is, and while mining lbry, I am able to mine at full intensity and play 3d games at the same time.

I am working on a mod to my batch to allow selecting specific gpu's per batch instance... this way you can trim intensity per card, and have one connection per device to have more individual information provided on the zpool web interface.

Very nice JK :)
EVGA k-boost tool .. I never heard of that and to "keep" cards at the p0 state throughout all P-state changes  fantastic ..very nice do you have a link plz  :)
One connection per device is great too. Very nice.
I see you have a cooler too.
ps my cards are in the p2 state now except the 750ti of course.
Thx
EDIT:I didn't know kboost would do that.. I don't understand how that would keep them in the p0 state.

Have you ever used steam? :  Http://www.steampowered.com (http://Http://www.steampowered.com)

Just go to library/store and search for EVGA PrecisionX   That's how you download a copy.

It's just a i7 920;  nothing super special....  But the case is HUGE and heavy.  Holy cow.  Seriously.  Huge.  Ill either be adding a 3rd video card to this unit in the future, or ill be adding my FTA-PCIE adapter ;)

Next to it is a Dell Precision 690 with 2x X5365 Xeons and 24Gb of ECC Reg ram, as well as the upgraded 1000W power supply.  With an optional riser card you can install 2 16x PCIE cards, but when I ran two, I just jimmied one of the risers into a 1x slot.  That machine is a good reliable number pounder that I am looking to sell finally.  I have a 20 core machine to replace it which presently mining for me up in SF.

Ive been running all my cards in P2 as well.  I have kboost disabled for now.  The older ones like GTX 550, 650, 750, etc... seem to run in P0 on their own... My watercooled GTX 480 would run in P0 @ 75-80*c when mining and not thermal throttle surprisingly.... and that same single width mini radiator would cool the GPU and the i7-920 while mining Neoscrypt.


We just got our LBRY block.   for a 10.2% share reward, I got 0.011 BTC.  Now that I am where I belong at a little over 30% share presently..... that's a nice return if we get lucky again soon!   I am in it for the long haul on that algo for now.
The card may sit in P2 state, but voltage, clocks, and etc are all set to P0 settings.  no matter what the power state table it reads from, the table is the P0 table.  This is how I understand how it works.

I did see a % increase of hashrates when enabling it.

Note crashed this morning ... zpool  lbry algo
Cant stabilize it... trying something.
Note after all this time now I cant get all cards to mine and sometimes on reboot the 980ti drops out too and sometimes on reboot both 970 drop out.. not recognized.
Code 43.
Crash boom bang ??? ??? ??? ??? ??? ??? ??? ???
Unplugging it for 2 minutes

OK running again must go into the asrock bios and change from fast boot to normal boot.. this may help for code 43.
crash

Getting System Interrupts running cpu at 100% looking for solution
Edit: it does that when the drivers aren't fully installed ...after a crash.

Took the 970 out . till I have time to look further.

Now the one 970 isn't hashing i think the fix is to throw them away.. garbage cards. oc'ing themselves to 1417  wtf
I'll never buy gigabyte again.

throw away that relic, buy a 1070 really worth the invest imho, it's a great card very stable no problem i can let the rig run for days

also very high profit right now with lbry ive already mined 1 btc(actually a bit more...) in 15 days, with 7 gpu....

Thx Amph  I'm going to call gigabyte and see if I can trade them for a 1070. ;) those cards are bad 970 i have.

Amph what controller do you use again  afterburner only supports 4 cards like precision x garbage. :D
thx
Is that afterburner Amp your using ? does it recognized all 6 cards?


https://ip.bitcointalk.org/?u=http%3A%2F%2Fi.imgur.com%2F22OjBd2.png&t=567&c=cD5ZKSAP5pnzNw

How does FTA-PCIE adapter work? I dont see where you add a card to it. and how it would work. thx

yeah just msi afterbuner last version, windows has a problem at first when i plugged all the card, in recognizing the last one, but after a couple of restart everything went well

maybe do not plug them all at once, i have  abetter hash now, peak was 1510

 :-\ :-\ :-\ :-\ :-\ :-\ :-\
What is that app? Driving me nuts. :o



https://i.imgur.com/FqoCxO0.jpg

antivirus? i think you need maybe a format c with a clean install, maybe install only the necessary things for mining in a separate machine if you have one

Its been mining now for 3 days no problems.
Its not the antivirus but something in windows on reboot not sure.
My next thing to do is take it off fast boot to normal boot.
That type of crash report is the drivers not installing all the way.
I dare not turn it off right now.. lost a lot of btc but another heat wave coming and I'll have to shut it down for 4 hours a day for 7 days... then I'll change the bios to slow boot.
It has 20,000 accepts so far. :)
But that is only one of the crash problems.. the other is why are they clocked at 1417 way out of range causing a ccminer crash? Bad cards? IDK
Maybe be doing an rma on both cards.

Ok trying  some things now.


Did an upgrade on bios not long ago.
I have intel drivers doing the mb hd video.
I dont know how to turn it off.
Totally deleted afterburner.
Setting bios to to reboot normal speed.
And then going to try it out.

Nope...... it does mine for 7 minutes .... then ccminer was stopped by an app.  

Problem maybe heat related.

ccminer1.8.2.exe  -a lbry  --cpu-priority 0 -o stratum+tcp://yiimp.ccminer.org:3334  -u  -p   -d 0,1,2,3,4  -i 23,0,17,17,23
A little low on the settings .. but its working so far.
Finally one problem solved... needed intensity setting for each card.... the 750ti I left at stock setting.

https://i.imgur.com/52b9Wov.jpg

Look at the edit I made to your string.    I suggest not polling the card with ccminer if you don't plan on hashing with it ;)  Take one more thing out of the equation....   I mean;  I see results for your 750Ti; 50 Mh... but you are putting intensity to zero?   Maybe I am confused after looking at it once more...


But I have found that some cards will take different max intensity settings between them as well.  Some have better cooling for their positioning in the casings, etc.  Lots of variables... but it looks like you are figuring out the stability issues.

Thx JK ..... yes I think 0 means default intensity... something in the back of my mine says to do this for the 750ti.
Wait I see now.. with your bat file, it wont mine with the 750ti... need that command. It goes in the order the -d calls.
Next will see if it can mine at 10 degrees above room temperature.  :)
It's 62f or 16.6 c in that room and was mining at normal room temperature. Closed the windows ... see what temperature goes up to.
EDIT: Starting to crash at 74f. With no external fan.

I have an intel 1150 socket 2.9ghz g1850 2 core cpu on the rig.
Would it help oc'ing this a little? In fact I would like to try this...but only a little.
At 95 Degrees Fahrenheit = 35 Celsius summer temperatures ..it runs at most 45c.. so it runs cool for the summer heat.
Now it is room temperature outside and inside as winter is coming.
The specs on the miner are on the front page.
Should I try for 3ghz ?

Any help plz as I have never done this before. 

Thank you

Now I get this on crash. I think I'll name this crash rig 2. ;D



https://i.imgur.com/yGnyykB.jpg

Yesterday I tried something that would definitely crash the rig...its been mining now for 24 hours with this bat file.
Amazing. I just don't get it. The only thing that changed is it is cooler and using no fan control or oc'ing software.
ccminer1.8.2.exe  -a lbry --cpu-priority 3 -o stratum+tcp://yiimp.ccminer.org:3334  -u   -p     -d 0,1,2,3,4  -i 24,0,19,19,24

EDIT: I did turn off the on-board hd graphics.

I wish there was a program to test everything on the computer.

Your scores are low. With the lbry sp-mod #4 you can get 190mhash on the 970, 290mhash on the 980ti easily...

Here's the problem with that sp it may crash... see the intensity setting for the 970...if increase it ..it may crash.
I should be getting 150mh right now, but lowered the intensity to keep it stable.

It's pretty interesting that you keep promoting the #4 when you don't send it to who paid you, like me for example.

Btw with #3 it was 170MH/s (minus 3.3/3.5% = 160/164)


Hi

I would suggest you to make separate rigs, with just a single type of VGA. It's better this way, trust me ;)

ps: oc'ing your platform won't make any difference, don't bother

Thx...yes oc'ing won't do anything.
I built this rig to hold 2 mb 2 psus 12 980ti's ect but got interupted financialy.. so I put what I could on there.
Yes all the same cards is the way to do it like my 750ti rig. :)
Now that its been running for 2 days stright .. I'm going to try -i 18 on the 970's see what happens.
Thx

That's more like it. :)  ccminer1.8.2.exe  -a lbry --cpu-priority 3 -o stratum+tcp://yiimp.ccminer.org:3334  -u   -p     -d 0,1,2,3,4  -i 23,0,21,21,23

I know its a late response but.. that psu is setup to draw the mb, 1x graphics,and all the risers off of one rail A1..and part of another graphics card too... very bad design.

I found only 367.27 driver supports OC functions under linux. And I need cuda libraries to use ccminer, but on nvidia site only 8.0.44 version is available which depends on 367.48 driver which is not support OC functions.
So I'm looking for cuda_8.0.27_linux.run file.
Is anyone who have it can share it?

Hi try posting the question here.  :) CCminer(SP-MOD) Modded NVIDIA Maxwell / Pascal kernels.  thread.

https://bitcointalk.org/index.php?topic=826901.0

Seems to be a bunch of bad risers was one of the main problems. Need to test it doing lyra2re2 ect.
The risers that have the transistors on them and a molex connector instead of 4 pin.

Hi I want to enter the world of mining that I recommend and that you think to buy I am interested in the gpu

Please clarify thank you.

Sorry so late in responding to the end of the problem with my rig. :)
It was the cheap type of risers. :P
Thank you all for your help.....much appreciated.

Update...and 1 usb3 cable was bad too. No wonder I was going nuts. ::)  :)
Again ...thank you all for your help.....much appreciated.
