I have a 1200 w power supply, i changed the riser twice, same result. i used the gpus 1by 1 that's how i find that 1 is not working properly.

The card was working close to 1 wood (part of the rig now is at 5 cm) maybe the card could overheated. i dont know if i still can save my card.

Hi thanks for your response,

I did that already, i used the original bios and i use just that card, but when i open the claymore program i can watch that it reads the card but go to black screen before the DAG creation, i uninstal and install the last AMD blockchain driver but the result is the same.

and yes, im using the pixel patcher.

Hello guys,

I have a problem with 1 GPU wich is a RX 470 4Gb MSI gaming, this GPU go to black screen after i open the claymore program to mine, i flahsed the card to the original BIOS but the problem persists, apparently it crashes before the DAG creation,  this gpu is in 7 GPU Rig, the others 6 GPUs are working fine.

what do you think? can i still save my card?

The easiest  way without connect or disconnect your GPUs is using the command line -di ( -di 0123456 means all GPUs are disabled, -di 012, means GPU0, GPU1 and GPU2 are disabled) and watching physically wich GPU fan is working. Hope It helps.

Im using  the Z170A M5 without problems 7 GPU.
Your motherboard shouldnt have any probem, did you install windows in UEFI mode?, did you disable Windows 7 instalation and enabled Windows 8 + in the BIOS?

Use it, difficulty is raising day by day, hour by hour.

kinda, i have problem with just with 1 rig but the rest of them are working stable, im gonna install some fans to help with the temperature.

yes, i dont like dual mining because is too much draw energy,but im thinking to lead 1 rig to ETC or ZEC

Not really i sold most of my ETH, i should have keep with them but life is hard.   

fixed it

Hi guys, i make this to say thank you to all the smart users in this community who help me to build all my rigs sharing their knowledge.

I live in south america, in mi country electricity it's not cheap (0.16 - 0.20 KWH), especial equipement like GPU and Motherboards are not very cheap neither (10% - 30% more than in USA) so i have to fight for them, I started in this world just for fun.

So 1 year ago i didnt know anything about crypto so i bought a Bitmain Antminer s5, big mistake i had 0 profitability.

Then i build my first rig whit 1 GPU rx 470 sapphire (not available in my country)

With the ETH of that single card  i bought another card and i built a frame

Finally 5 months ago i finished my first rig with 6 GPU (the only rx470 model that i could find in my country)

So i said " i have 1 i can  make it 2", and i bought more gpus and i built a 7 GPU rig

Not fancy i know, now i'm addicted to mining and i build 7 rigs.

Well, now i decided to stop building and try to help to another users who wants to mine, my rigs are a little stable but im  still fighting with some of them.

And this is my hashrate with one of them.

Can you post the link of the news about PoS ETH?

and  other question, how much exposure ethereum blockchain will be? do you think it really worth for them change PoW for PoS?

Im building all my rigs in MSI Z170A gamining 5 and a lot of RX470, im trying to nost waste much money. I cant find any asrock H81 on my city.
