Topic: 3 Cards burned after 14hrs? (Read 1263 times)

15-20% less power lowers heat a LOT more than changing miner software.

 8-P

DSTM makes the cards run hotter, the EWBF miner works best for lower heat.

 I was seeing 509 sols/s at 70% power with +200 core +700 memory on my EVGA SC 1070 ti cards using EBWF - I think DSTM was a hair higher at that setting but can't remember for sure.

 They also run cooler than at 85-90% power with lower fan settings - 56C at 52% fan when I was testing that setting in an 80F ambient room with my standard Afterburner fan profile.

 I don't have any of the MSI blower models, but I do have a pair of ASUS (one 1080 ti one 1080) that are a very similar design - they DO run quite a bit hotter than any of my "fan-type" designs, but it helps a lot to remove the mounting bracket for better airflow.

If the USB is a Lexar I think that might be the fault. I bought a Lexar USB 64 GB 3.0 for my work and it burned out within 2 days, I only did a few copies and never put that USB outside work computers which are all protected from viruses. It used to just pulse and showing nothing on screen. I think a cheap SSD 60 GB can solve your problem. I don't see any Linux OS causing trouble, they are well known for running years without a restart and not restarting all the time so something must be wrong with that USB drive of yours.

And lower the memory clock to +500 max and core clock +100 max. Pushing your cards too much in Windows causes nvidiaklm.sys error or Thread Stuck in Device Driver in AMD cards, don' know about Linux though if this maybe a reason.

On both the Zotac Mini 1070 ti and my EVGA SC 1070 ti cards, I use a power setting of about 105 watts (I vary this up to 5 watts either side to hit my "target total machine power consumption", with very small effect on efficiency), +200 core +700 memory using nvidia-settings.
 At 105 watts, all of my 1070 ti cards hit right around 465 sol/s for 4.4ish efficiency.
 50% fan setting in a room that is 80F was putting the card temps in the low 50s (EVGA) or mid 50s (Zotac) as long as I wasn't putting the card air intake right next to the CPU on the motherboard.

 I'm not sure how nvOS settings compare to nvidia-settings though, I've NEVER seen a card that worked at all with +1000 in nvidiasettings on the memory clock.

 The memory speed DOES make a noticeable difference in hashrate.

https://bitcointalksearch.org/topic/m.23996225 for my initial testing under Windows - I never did figure out why the "60% TDP" setting in Afterburner was only giving me 103 watts though (it should have been 106).

O.c so hig

you are wrong, the limit set to 82-84C depending on the model
once card reaches that temperature it starts to trottle and reduce the core clock trying to shut the temp off.
of course you could still to bur the card... but it is more difficult now

I never raise the temperature of my GPU above 58 degrees. 70 degrees is the limit for GPU. But I think that is not the case. Did you have any problems with the power supply. If the power supply also worked to the limit could cause a power surge. This is enough to fail a large part of your equipment.

I looked into simplemining but i feel as i'm starting nvOC will allow me to make more small mistakes ( that i need to learn ) and allow to better understand the principles.
As i expand into a mining farm problably will look again into simplemining. For the time being i'm mostly learning, will complete the rig in the next couple weeks (will add 3 more graphic cards).

simplemining  is 2 usd a rig a month  uses linux  allows clocking and monitoring.  If you have bigger rigs 2 usd a month is cheap enough.

I like nvoc   but it is not as good as simplemining   for maintaining multiple rigs in multiple locations.

Still doing some setup work for winter mining.  But I have  3 simple mining accounts  with  13 rigs in all  So I pay 26 usd a month  but the rigs earn 3000 usd a month

so under 1 %  it  is worth it to me.

I will be setting up a 4th location  much larger it is 1 hour and 10 minutes from my house. 
Simple mining will earn its keep  as that spot will have a lot of rigs and I do not feel like driving to change shit  more then 1 time a week.

try windows and check it. if you have same problem then send me your configuration file...

What are your settings if you don't mind asking? I think the main problem is on the USB stick, and it was the reason that system crashed and not the OC speeds. Even if for sure i was pushing the MC way over what needed.

Do you recommend anything to remote monitor the rig using nvOC? I think i will end up using teamviwer but was looking for other alternatives

I was thinking about turning the memory clock negative since it should't make a big different on zencash. As i said above the system went down again but i belive it's a issue with the USB drive.
Formatting the USB and re intalling nvOC is the only thing that gets the system back and running. Will try with a differente USB to see if i get better stability.
At moment i'm running with memory 600 and clock 140, power limit 110

Will try these settings for the next 24hrs, and go up by 5 on clock if i don't get any reboots.
Thanks for all the advices

You are pushing those cards too hard with the overclocks, most cards don't run with clocks too high.

I get over 510 sols on my EVGA 1070 Ti with these settings below with the temp at 70c using the zm miner.

Set the memory to -303 and the core to +140 and power to 85 - 90.

Lower your overclocks and keep the fans above 90% to keep them cool.

Thanks for the input, yesterday i managed to put the rig back and running (i belive the problem is the USB drive since it now has happen again and the rig was back and running after formatting it).
I went down in MC to 600 and CC to 150 as soon as i managed to boot the system and was getting around 460sol per card.
Now i'm starting to think the problem is the USB driver where i have the OS. The system again was running great for about 24hrs and then stopped working and it only boots nvOC to the login screen, when i try to log in with the password it reboots. I'm now formatting the USB to intall again nvOC to make sure that the problem is there, waiting for Lexar drive at the moment, but i think i will end up going with a ssd

Yea its pretty obvious that your cards cant handle +1200Mhz mem clocks, hell there aint a single card that can do that! Some samsung chips cant do even +800. Best are usually +1000mhz. Im suprised your rig didnt crash right after the 1st miner launch with those insane clocks.

@OP. Linux is more for advanced users.
Might want to start of with default settings in Windows and tweak through after burner.

More straight forward than making errors keying in numbers that you don't necessarily know how far off are from the default value.
I used NVoc and gave up soon after. Not much benefit in terms of hashrate and definitely not user friendly.

While I'm thinking about it - do your MSI 1070 ti Aero cards have a ball-bearing blower?
My research to date has been inconclusive, MSI hasn't replied to my direct question yet, and the ASUS variation on the same theme that IS ball bearing is out of stock....

It's highly unlikely that you got a faulty batch, but possible though. However, I'd try resetting or lowering their clocks as already suggested. Be extra careful with such expensive GPUs, it's not that hard to roast all of them if a power cut or sudden power surge happens, I'd suggest buying an external UPS to secure them.

 1070 ti pulling 480 sol/s isn't pushing hard at all.

 70C though is high on temp for 115 watts, especially with 80% fan - SOMETHING is blocking airflow to the cards or the room is VERY VERY hot.
 Those Aero blower cards shouldn't have THAT bad of cooling, though they would tend to run a LITTLE warmer than good fan-cooled cards unless they're in a case.

 My EVGA and Zotac 1070 ti cards in my "new shelf/rack" first rig only run 62-63C at 50% fan in a room that is 86 F measured right above the "room fan" that blows air into that rig.


 It's POSSIBLE that you got a batch of flaky cards - but if they're working for video playing it sounds more like you're pushing them too hard, probably on the memory clock.

Shoutout to this man. Take his advice. He is a honeypot of information around here.

mc 1200 jesus christ chillll man haha just lower them bad boys and try again

your clocks are too high

set them at 145 for core

and at 1000 for mc

480 sols  meant you stretched to the max

with 175  and 1200


once they work  with

145 and 1000


bump

to 150 and 1000


you will be closer to 450  sols  but it won't crash

The PSU it's a EVGA750CQ Gold.
I find it hard to belive that all 3GPU's have burned, i tried the GPU one by one (disconnecting the connection from the motherboard of the other 2) and was getting the exact same ploblem, but i guess it's possible.

well, I doubt that it is possible to burn GPU like that, cause all nvidia gpus have some kind of protection for overheating, it will try to reduce clock
or just reboot system
I think it connects to your PSU - check the cables out of PSU and coming into GPUs - what the state of them? are they ok?
what kind of PSU do you have?

I've build a mining rig with 3 nvidia 1070 ti AERO and used a Asus Prime Z270-p motherboard.
I'm using nvOC and I've already enabled above 4G decoding and reset the security keys on the BIOS

Initially the system was booting fine, and i've set up the cards with CC 175 and a MC 1200, power limit of 115W and fan 80. On the 1bash
I've opened the miner terminal and it was mining around 480 sol's per card, with a temperature around 70 oC, i've letf it running for about 5hrs before turning off the monitor and going to work, at the time temperature were stable at 68oC with occasional spikes to 70oC.

According to the pool i was connected the rig was running for around 14hrs and just before turning off there was a spike in the sol's on the graph (nothing crazy). When i got home the RIG was on the bios. Now when i boot into linux if i leave the terminal open it crashes and reboots. If i close the terminal i can use the system, i can go into youtube and watch movies in 1080p, see the gpu's detected on the nvidia app with no arthiphacts.
If i try to run the mining terminal it crashes strait away, opening just the terminal without running the mining bash it also crashes but takes longer.

First of all, do you think it was possible to have burned the gpu's with those settings with around a total of 20hrs of work?

What can be causing this? I've already tried changing risers, formatting the USB and running it again, connecting the GPU one by one and all of them show the same behaviour
