Greetings to all fellow miners,

I've been running my rig steady for about two weeks and everything seems to work fine.

What bothers me is that today i felt a strange smell coming somewhere from the motherboard/psu. I cannot describe it as a burning smell, something more like the smell from new hardware being burnt in (if i can say it like that)

The rig is still working fine but i am not sure will it work in the future.

I'll put a screenshot here where you can see the power consumption and clocks.

The rig consist of 1 x ref Sapphire 480 8GB (flashed bios with low power consumption.rom), 2x rx 470 MSI 8GB with and 3x Rx 470 Sapphire Strix also 8GB. The 470's all are bios edited with 1500 and up strap copying, undervoltet with STRIX to -120mV, and clocks set to 1.100 and 1.750 memory clock for MSI (stock is 1.650) and 2000 (stock) for Sapphire. Mobo is AsRock BTC pro, PSU is Corsair RM 1000i. Every card is connected to the mobo with power risers.

As i said it works steady for two weeks, and i am getting around 160 MHS, with power usage from the wattmeter around 830-860W, and Corsair Link 900-920W.

I'll kindly ask some more experienced miners to take a look at the screenshot and check if everything is ok or should i change something.

Thanks

Regards,

If your parts are new then its normal. Probably some flux being burnt off. If something actually burn your rig would shut off or at least that GPU would crash.

Ok, that's what i initially thought. Thanks for your reply.

I guess I did have my cards undervolted when I went to undervolt them again yesterday they were already set. They were set to -12 in afterburner.

Tried it on a cheap old MB again and same thing happened, a puff of smoke from the front part of gpu and computer immediately shuts off. Guess it happens just weird I haven't read about it happening to anyone else yet.

You guys think it was the cards fault right? Should I change my breakoutboard or server power supply? HP commonslot 1200 watt powersupply with gekkoscience bb. Had a 7 card rig going with 4 470s, 1 370, 1 380, and a 1070.

I think I'll start the RMA process this weekend.

I think it's something with your PSU, but i am not sure. Did you tried testing your rig with another one? Few weeks ago i wanted to test my new PSU using my daily computer, but i ended up burning my HDD. Problem was that i used SATA power cable from another PSU, because i didn't know that cables from different PSU's aren't same. Luckily, nothing else died and my HDD was exchanged in RMA process.

Good luck
