Hi,
this is my first post, so be gentle please.
My PC restarts few minutes after I start Claymore dual miner (eth-dcr). I tried to limit power draw anywhere from -15% to -50%. It says my power draw from the wall is 700-1150w depending on settings. No matter what settings I put on Wattman it restarts every time. I tried 2-3  drivers and it didn't help. Can you point me in the right direction because I am totally clueless?

My rig is:
PSU FSP aurum 1200w PT
4x Asus Vega Strix 56
CPU Pentium G4400
MOBO Gigabyte GA-H110-D3A Mining Ready
RAM Crucial CT8G4DFD8213
SSD Kingston uv400
Riser card ver.008s

Start your rig with only one Vega connected and see if this restarting continues to happen.

troubleshoot your pc by trying 1 vid card, then 2, then 3, then 4. sometimes it maybe some other pc component driving your computer to restart.

I did. It happens anyway. But i think I found the problem. Can you tell me what temps in red boxes should be?

Im pretty sure they shouldn't run hotter than 80C

Don't mine with those cards with 91C avarage temp ... You are killing your cards , your pc probably shut down bc the thermal protection ? ??? Its maybe just a reading error , you should check that temp with another software also
You should keep that temp under 80C  , better around 70C for a 24 hours mining ...

If you keep doing what you doing you killing your cards within a short period of time ....

What is telling you exactly your rig is pulling 700-1150 watts at the wall ?


Did you checked the temps with gpuz also ?
What temperature GPU-Z (https://www.techpowerup.com/download/techpowerup-gpu-z/[i) is reporting ?

If I had to guess it is probably just the power draw of the cards themselves, not the whole rig. Unless he's running it off a battery where the discharge can be measured.

Whenever this happens 90% of the time it's the USB risers.

If not that then it's either overclocked way too high for the voltage. Bring back to stock for a while and test that way.

If it crashes then it's your risers.

... or maybe the 94.4 C gpu hot spot temp and the 91C avarage GPU HMB temp ;) what the OP get on his cards ...

Mounted a new rig this week and i was fked up because it was going down every hour more or less. After some testing (risers, cables, power, psu,etc...) i came down to check the basic and pulled off the reset connection at the power jumpers. Running fine for 3 days now :)

PS: fekin asrock h81 its shit compared to asus mobos ^^

Are you perform dual mining?
Try to lower the target temperature and increase max fan speed.

i have the same problem my rig restarts every few hours i dnt know why

my power draw from gpu is 130 its too much how can i lower the power consumption ?

it is just because your psu is not enough for 4x vega 56. Try using 3 or 2 first, then sometime later 4th one. But in any case, problem is your psu, try to connect a higher one or make it dual psu.

Thank you all for the reply.
The power draw is measured with wattmeter, so it's the total draw from the wall (but I lowered the power limit). The problem is that card is adjusting fan settings according to the gpu temperature and ignoring the others like HBM. I put manually to higher RPM and everything was really cool except HBM on max temp arround 80C. I guess I should undervolt it because it is 1.25V stock. I am testing it again and will report back in 10hrs or so.

Are you aware of the double performance mining VGA performance becomes less than the maximum? Better focus on one mine with maximum results.
Try to do one mining, is there still often a restart? And do not forget to see the temperature not to 80C, if using the application after burner immediately lower the memory clock and core clock.

I put fan on manual and it solved graphic cards problems. But where is this "Temperature 4" sensor on MOBO? It goes over 93C

It can be windows update problem if you are using windows, be sure you have turned of windows update.

It is disabled. Do you know where could be that part so I can put better heatsink on it, or put one fan near it?
Here is the photo of mobo http://static.gigabyte.com/Product/2/6345/2017062118074522_big.png

why not just placing a high cfm fan (https://www.amazon.com/Corsair-AF140-Quiet-High-Airflow/dp/B00F6S0XL2/ref=sr_1_sc_1?ie=UTF8&qid=1520015075&sr=8-1-spell&keywords=high+cfm+pc+cooling+fan+corasir) over the mobo , and let it blow air to the whole motherboard ?

80 degrees is a lot. I have in the settings Claymore is off at 72 degrees. It is possible to switch-off rigs OP in the same range. I never allow my GPU to work at temperatures above 60 degrees. It is in dual mode. It's cold in my country now. Therefore, my rigs are not heated above 50 degrees. I think this is the best regime.

I found the spot. It is south bridge, and the gpu is right above it, so it does'nt have proper airflow. I put the fan near it and it lowered temps from 95+ to 81-82. Will repaste it with kryonaut. That way it should go even few C lower.

Just look at your GPU's temp, why you let it over 90C.
Make it cool with below 65C, your rig will be stable for 24/7 operation for sure.

Glad to hear that.


Have you tried other system information utility software? Just to make sure that what shown on HW Info is accurate. If you think what shown in HW info is accurate, you could try this advice.

It was south bridge problem which was fixed by applying thermal paste and gpu fan-stop which was solved by setting fan to start spinning on lower temps. Temps are now arround 60C for core and 70 for HBM2
It should be stable now. Thank you all for suggestions.

I have another problem now. Three cards worked like a charm. But when I add the forth it restarts after few minutes. Tried to change different risers, tried to change gpu, tried to change riser power cable and it's slot on psu, tried to change pci-e slot on mobo and even tried to put power cable from 4th gpu on other one. Yeah, and I tried to lower power consumption. Nothing helps. So only thing that is left is some software problem I guess. Is there some bios or wattman setting that could cause this? Got new mobo btw. It is Asus prime Z270-a. Bios update didn't help too.

I found some ASUS MOBO settings you could try:

Advanced mode (F7) -> "Boot" section -> set "4G Decode" to ENABLED.
Under "Boot" -> set FAST BOOT to DISABLED.
Under "Advanced" -> Onboard Devices Configuration -> set HD AUDIO CONTROLLER to DISABLED.
Under "Advanced" -> PCH Configuration -> set PCI-E Link Speed to GEN2.

Note: Some users have reported GEN1 working better with the ASUS PRIME Z270P. Try that if you have that board.

But usually restarting screams power supply not providing enough power. Does it restart when you start the miner program or just when idling?

Thank you for the suggestions. From this settings I only dont have FAST BOOT DISABLED. Will check that settings soon.
When idle it does not reset. I left it overnight once. When I start claymore it is ok for few minutes and then just crashes. It can be 2 mins after running claymore and can be 15 minutes. It depends, but I don't know on what. In windows event manager it gives me 6008 error. I have read that it could suggest overheating. But GPU is arround 60C. Hbm was max 75C but mostly under that and VRM gets to 80C CPU nad mobo are ice cold.

Still sound grossly like a power delivery failure. Something cannot get enough power and restarts the rig in the outcome. If you have a spare PSU you could try that.

The PSU was sent at shop to check it out and it was loaded at almost max load and working 12+h without restarts. I can't test it because I don't have second PSU powerful enough.

My rigs have been running at 88 degrees for 2 years now, yet you guys are thinking that 80+ degrees is a lot. :D

Around 85 degrees is just fine for GPU's in my opinion.

it's a right decision, on a GPUs Rig troubleshooting, the physical check is important, check devices position, temperature, etc.


That's nothing with mine. I run two days my Gigabyte Windforce 290X with the temperature between 91-92, I stop it cause my PSU was burning. Now, that card run normally, under 85 Lol. Yeah, it's normal if I compare it with the temperature before.

Wait did you say that bad psu caused GPUs to run 6-7C hotter?

Yes, for example, your PSUs didn't run on correct voltage, your cards would start drawing more power to attempt to bring the voltage back up. It will make your PSUs overloaded and also make your card working harder that would produce more heat and can make a random restart on your systems.

Looks like a legit cause. Thank you for sharing it with me

Yeah, of course, we are happy to help other members here. Report here what you've done after. It would help other members with the same problems.

Hi op. Are you still mining? Was the problem on this rig been already solved? How is it doing now? I'm interested to know because I have similar problem now. And I'm trying to make my rig dual psu to ease the load of the first psu and to see if it will be solved.

Can you tell someone if can i invest in mining? If is it real?

Check cards one by one there would be something wrong with single cards and that's why it is affecting the whole rig.

Sometimes it is one of the cards causing the problem. That's why I agree that you test your cards one by one.

Sometime what's causing the problem are the risers. Sometimes when the PSU is overloaded than what is capable of, can also cause the problem.

It is important to exhaust all the possible hardware problems. Then there is also the software problem to exhaust.
