I watched a video by someone who seem to have built a lot of rigs. He said to use only 2 of the connections per SATA cable when connecting risers.
I did that with an eight card rig, which used up the 4 SATA cable connections. However, I want to try adding one more card and use simplemining, I currently have two PSU's. Five of the cards are on THE FIRST PSU VGA connections and three other cards are using the 2ND PSU VGA connections.

This guy also said to keep the risers on one PSU. If you didn't, bad things can happen. Can you only do it this way?

Can I use one of the SATA connections and another VGA from the second power supply?

ASUS PRIME Z270-A LGA 1151
Windows 10
EVGA SuperNOVA 1000 G3 powering five cards and the risers, motherboard and SSD
EVGA 850 BQ just powering three of the cards

At this point, I have reloaded the latest Nvidia drivers multiple times. I reinstalled Windows 10. I've updated the bios and checked settings -- I have another rigged with the same exact specs except the cards are not the XLR8 VERSION. i'VE REINSTALLED msi AFTERBURNER.
-I've run only four cards on the PSU 1000 just fine. Changed the riser and card that was disabled -- of course that new riser could be bad also.
-I've run the new card in riser, and three of the cards work fine on the 1000, and 4 other cards on a different PSU. Still got triangle error in device manager on one card.

I still can't get that eight card running.

1000 PSU - hooked to risers and 5 cards
850 PSU - hooked to 3 cards


If I try to run all eight cards, I get an error triangle in device manager on one of the cards.

If I run just 4 cards on the 1000 PSU, it runs fine. So, I changed the card and riser out that I had disabled. Nope. I get the same error trying to run 5 cards.

So, I tried running 4 cards and all of the risers on the 1000 PSU. and a completely different PSU 1050, for the other 4 cards. I get that same triangle error again.

It seems to run seven cards okay. However, I was having Internet problems. I am mining zcash. If the Internet goes out, the miner won't restart.it just keeps saying trying to restart trying to restart trying to restart.

Also, my settings in msi afterburner completely disappear now when Windows restarts. I'll try uninstalling and reinstalling later maybe.

70% should be okay

set clocks

to

tdp 70%
core +10
ram + 100
fan 75%

see how that works

I use these parameters, except have the fan on auto. It looked like it was running at about 57%. Fired up five of the cards yesterday at 10:30 AM and ran stable until I went to bed at 10 PM. However, sometime in the night it stopped again. I am mining zcash and using the EWBF CUDA Zcash Miner. In the mining apps window it was continuously trying to restart. I close the window, and tried to restart the minor but it would only flash for a split second and disappear. When I restarted the rig, I pulled up MSI afterburner and all my settings were gone again. So after resetting, I have fired up the five cards again with the  fans set at 75%.

Is it okay for the cards to run the fans at 75% for a long period of time?

Not sure where to go from here. I have tried reinstalling the miner software as well as a refresh copy of Windows 10. Could it still be a hardware issue, even though it ran for so long? still haven't tried another PSU on it.

this is a general question. I am trying to troubleshoot my rig. Should there be any problems with my  cards running if I take them all down to 70% power limit?  Or do certain cards need more power to run correctly? I have GTX 1060 3GB cards.

I figured if I try running them at a lower  power limit that they would be more apt to be stable. Is that right or wrong? I've been working a week trying to get this rig to go. It just keeps restarting or stalling.

Tomorrow I try another PSU on it I guess.

I am going to give this a try.. It looks like it will help me.

Device 3 is the device that keeps stopping first when I get a stall in mining.  I assume that that is GPU 04.  How do I determine which device/video card it is on my rig? Such as... Does that mean that it is the one in the fourth pcie slot?

Okay. I would like to do this but I am not sure where you disable just one of the GPU's.

Since my device 3 has been the one to stop first the last two times after reading my log, I am guessing that that is the problem.  I'm running Ali carts again now to see if I get that same device to fail. And trying to figure out how to disable the deviceand determine which card it actually is.

So it ran for 10 hours last night and then the devices fell off line.

I am mining zczsh. When it stops working correctly, it gives me the reading that 0 sols are being produced. The miner window is still up and all of the GPU's keep trying to restart but can't.

The last two times, the first device listed is, device 3. With the following log readings.

Device 3 thread exited with code:  77

Then all of the other GPU's exit with the same code 77.

Yesterday,  I tore it down so that they were just two cards running on the 1000 PSU. I ran it all day with a power limit of 70 and memory clock +476  individually on both cards.
I added the third card when I went to bed and woke up to a frozen screen again.  So, I replaced the riser on the third card..

Six hours ago, I attached two more cards to the 1000 PSU for 5 total. But this time I placed settings for all five at power limit 70, memory clock + 476, core +46..

I also  reinstalled  Nvidia drivers to the latest,  version     384.94

It's been running fine for the last six hours with temperatures  on the cards between 66 and 69°C. I don't have any fans on them and the window slightly open. It's been 96°Fahrenheit out today. air-conditioners in the other room.

471 W total.

I guess I'll let it run through the night and see what happens. tomorrow add the sixth card off the 850 PSU.

So I'm not sure if was a riser or settings. I just hope it's working good now..

2.5 hours.  must have been an error. windows retarted.

so that's where I've been with this rig.. It may run for two hours. It may run for four hours. It may run for one hour. But it won't run steady..

Thankfully the other rig is running like a champ.

I used kill a watt to get wattage reading from each power supply when it was mining and the 1000 PSU is  at 700 W and the 850 PSU is at around 300 W. So 1000 total. I took those readings when I started without changing settings.

So now it's been running steady for two hours at power 80%, memory 400+. the two hottest cards are now about 73 and 74°C. I'm holding my breath.

It's still 80° Fahrenheit in that room I have the window open. 89° Fahrenheit outside..

I will try the suggestions.

I am also going to bring the rig out to the bigger room where it is a little cooler and see if that changes things..


I ccurrently have it set to 80 power right now with 400+ memory  and I have two cards running hotter at 74, 75. The lowest are 64 where the fans are probably hitting them.I'm sure it will freeze pretty soon.

The rig in the small room freezes. can't move the mouse sometimes. screen goes black and just have to power it down and force restart.

a couple cards run at 78 degrees, couple at 75 degrees and some near 72 degrees. depending on where i put big fan.

I've reinstalled drivers a few times.

I just got into this last month. Hope this is the right place to post this.

here's my setup:

Custom-built case 30" x 18" x 12"

rig 1
8 PNY GTX 1060 3 GB    MPN:   VCGGTX10603PB
ASUS PRIME Z270-A LGA 1151
Windows 10
EVGA SuperNOVA 1000 G3 powering five cards and the risers, motherboard and SSD
EVGA 850 BQ just powering three of the cards

rig 2
8 PNY GTX 1060 3 GB    MPN:   VCGGTX10603XGPB-OC-BB  XLR8 Edition
ASUS PRIME Z270-A LGA 1151
Windows 10

I have the same setup on two rigs.. Except different version cards. on rig 1, I was able to take the power limit down to 68, core clock 46, memory clock 456, fan speed is 45. It is running at mid-60s Celsius. no problems.. I do have it in a larger room..

Rig 2. I have this in a smaller room. I have eight cards working, but it keeps shutting off. I am unable to take the power limit down. These are fancier cards with backplate. I have fans running on them. I also have the window open.. Trying to blow the air out the window. Trying everything and I can't get this to stay stable.

It's 80° in the small room. My air conditioner is in the main room where the other rig is at. I was hoping to put both rigs in the smaller room.  It is getting plenty of airflow around the cards.

Would Linux be better?
should I start pulling cards off one at a time to see if it is stable then?

I ordered an air conditioner for small rooms. Will that help?

It is supposed to be mid-90s here all week and who knows what about August or beyond. Thanks for any help. I used to watch gold rush on discovery and now I know why those guys get so antsy when their mining rigs are not working.
