Mining rig powers off

[roofgah]

Hi,

I have a problem with my mining rig. After a couple of hours it’s powered of completely and I have to reset the cmos to get it started up again. It’s not like normal shutting down but power is off. At the wall power plug is a device like kill-a-watt. Is measures around 1420 peak watt in full load. Temps in cgminer are around 80 degrees.
I read a lot on the internet but nothing is solving my probem. I cannot understand what is going on. Can someone help me with this?
It's not overclocked. The core and mem are default factory settings (1000/1300).

This is the configuration:
- 4x R9 290 Sapphire BF4 edition
- Asrock 970 extreme4
- AMD sempron 145
- Kingston 60gb SSD
- Kingston 4gb DDR3-1600mhz
- Enermax Platimax 1500watt 90PLUS ready!

- Windows 7

This is my config:
"shaders" : "2560",
"intensity" : "20",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "2",
"gpu-powertune" : "20",
"thread-concurrency" : "25600",
"gpu-memclock" : "1300",

"temp-cutoff" : "99",
"temp-overheat" : "95",
"temp-target" : "80",
"auto-fan" : true,
"api-listen" : true,
"api-port" : "4028",
"expiry" : "120",
"failover-only": true,
"gpu-threads" : "1",

"log" : "5",
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",

"scrypt" : true,
"kernel" : "scrypt",
"kernel-path" : "/usr/local/bin"

Thanks in advance.
Kind regards,
Rutger

I'm not sure but I think those variables are too high.
How much khashes per card are you getting?


BTW this thread should be in the mining sub-forum

I had a similar issue with my new 290x 4gb sapphire. turns out i was making a newb mistake and was plugging the 8pin and 6pin power cables in wrong. I was trying to spread the load out across the psu's cords.... bad idea i guess. make sure your not doing this and have the whole gpu on one cord and not two like i did. Hope it helps.

I was getting 800-880. It could run for 1 up to 2 hours stable. Temps are not too high.
It's this card: http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1227&pid=2091&psn=&lid=1&leg=0. So 1300mhz on mem is default i think.


@mitsanaga
This psu has 6x (1 cable with 2x 6/8 connector) I use one cable per gpu.

  what is the right way? 8 or 6?

Ok good. just wanted to make sure that wasn't the issue. after having to fight with that over the weekend. made me feel like a fool after having built so many computers for myself and others with out issue. lol

well in my case i have the seasonic m12ii 850w semi modular psu. there are slots on the left hand facing side for the semi modular cords. then on the immediate right of those is the permanent cords. There are three cords from there. One is the mobo cord, the other is your typical cpu cord. and then the gpu cord is there as well. HOWEVER. on the left side where the semi modular cords are plugged in, there is a slot or two designated for cpu/pci-e stuff. i tried to run the 8pin from the pci-e semi modular plug in, and the 6pin from the permanent gpu cord on the right side........ big no no that.


what ended up happening, is that, because asus is awesome, it detected power surges from my psu and would turn off the rig asap. Thank you Asus for being awesome. s


-edit- didn't see your second part to the question cause it was added afterwards. the right way is to use both. from the same cord. do not, i repeat, do not use two seperate cords like i did. It seems to cause a fault in the psu and a surge results, tripping the amperage.

is the mining ring powers off while mining or?
possible problem i can think is that power supply got bad or motherboard failure. but you neeed to give more information.

Yes it was mining at 3.2-3.4 mh/s in total. No HW errors and temps were ok. All components are brand new by the way.

 thankyou for the reply mitsanga
i'm troubled, i just bought the r9280x, used 2 cables to hook up aux power input  (and it is running hot)
on the CD that came with the unit, there were several manuals, but all are for hd 5xxx-7xxx series units. looking to the visiontek site, there also is no man for the R9. here is a screencap from the HD_7900 man:

  

 it is 06:30 here, i will call visiontek in abt 4 hrs when they get to work, and let y'all know then wassup with this  

[groggin]

 ok, i spoke to jeff@Visiontek, he says that both cables are required for the card to operate.
my psu has single 6+2 plugs @ cable ends and i have 2 cables connected, so it would seem that's right and i will have to look elsewhere for my temperature issue
thanks for letting me hang out 

[roofgah]

well thanks for the update.....
Can we go ontopic again?

Has anyone any ideas for me?

ASRock 970Extreme 4 cannot handle that much sustained current through the MB PCIE bus.

Powered risers will cure this.

Also disable all Cool and Quite settings in the Advanced UEFI Bios.

I have 2x x16 non powered and 2x x1->x16 powered risers. What do you suggest?
Cool and quiet is all on. So i will disable that this evening.

I have several of these boards.

Disable Cool and Quiet and CPU throttling as well all self regulated power functions.

Do that first and it might cure your problem.

Cool and Quiet enabled will do exactly what you are describing.

But two powered and two non powered raisers is oke?

Thanks! I will do that this evening and post the results.

Risers are independent.

The two powered ones will be more stable at high hash rate.

Yes but you said the mainboard is not capable to deliver the required amount of power, powered riser will cure this. Are two powered risers enough of would you suggest to use 3 or 4?

In my experience, sudden power loss like that is almost always sign of a faulty or overloaded PSU.

You have a 1500W PSU you're trying to run at 1420W (95% load) all day, every day.  Just a tiny momentary spike in load is probably causing your PSU to kick off an overload condition.  I try not to run my PSU's any more than 85-90% load at the absolute most.  Any higher, you'll have problems like this.  Maybe not the first day, or the second day, but it will happen.

[roofgah]

I turned the powertune lower to -13. And i see at the kill-a-watt device that i consumers between 1100 to 1300 watt. But the problem still exists. Maybe I can try running with 3 gpu's. In that case I expect that it will consumer 800-1000 watt. So this should run on a 1500 watt psu. Right?
