Please help on RX 480, my rig keep freezing

[huynhdat1989]

Dear,

I just begin to mine ETH on Ethos. And I build a system with 6 RX480. But the whole system is freezing after couple hours, I use sgminer-gm. I keep reboot and it still not working well.
Do you know what is possible problem on my rig? I use EVGA 1600W. I did not flashing, overlocking, keep all original.

Regards,

Back off to 5 cards.

show us the bat file  for sgminer-gm   you can leave the eth-address out

the psu should be more then enough

lastly  you are using risers    how did you hook them up?

1 riser per  sata cable is good
2 riser per sata cable is not good

Could you please list all of your hardware in detail?
What are your temperatures while mining?
What software are you using?

I use the ETHOS, so I dont have the bat file for sgminer-gm. Does Ethos cause problem?
I connect directly power from VGA supply to the riser like connect to AntMiner. I saw the data cable for each riser but I am not use them. Is it the problem when I connect directly power from VGA port to risers?

I just back off to 5 cards, and it still happen.
I have only 4 data ports on the PSU, if I want 1 sata cable for 1 riser might be not enough.

Ps: thanks Phillips, you help me not only on Bitcoin but also on EThereum.

Could you please list all of your hardware in detail?
What are your temperatures while mining?
What software are you using?

- Motherboard, 2x2GB Ddram3, Amd cpu, cpu fan, 16GB ssd from GPUShack.
- 2 x XFX RX480 8GB
- 4 x Asus RX 480 4Gb
- 6 Riser with 6 pin pci.

The Temperature of GPU is from 45 to 59 Celcius degree. Room temperature is 30 celcius degree.
I use Ethos and bgminer-cg.

never used ethos   but somewhere some place on ethos you have to fill in a line of info about the pool

what does the line look like?

[sigb0y]

Are you using bios mods?

no  he has not.

The file local.conf is:

maxgputemp 85
stratumproxy enabled
globalminer sgminer-gm
proxywallet 0xafe9bba709cbf6a5474a772b7556bd54e2aada0f

Why is that? I have 2 / 3 on one cable and everyrhing runs smooth (riser is 006c with the 6 pin power thing)

This is the default configuration
This what you are using?
This command for sure is missing... globaldriver amdgpu
And also some other lines for the settings of the GPUs

Yes Evakka, I just unplug and plug each GPU. I figure out 2 of them make my rig freeze when run individually. My GPUs is brand new, so is it the problem with the risers? Which risers do you recommend and where to buy it?

The rig still freezing. How is your rig, is it stable?

[evakka]

Switch the risers one by one so to find the faulty ones

Are they powered? They have to be for sure!!
Also what's the version of the risers, the suggestion is 006

When I switch risers one by one, how many hours for running to make sure that risers are good?

I powered all risers with 6pins, and 8pins with the GPU. The riser I use is 006. I just ordered 12 risers more.
The motherboard I bough is on Gpushack.com.

[huynhdat1989]

I just tried to plugin directly to motherboard, but it keeps freezing too. Do you know what wrong with my system? I bough used motherboard on GPU shack.
