Title: 1of the gpu always DEAD overnight Post by: epicjim on January 03, 2014, 07:49:34 AM I noticed this happening 2 days in a row. I have 2x Gigabyte R9 280x rev 2. The card should be fine because when I restart computer it works normal again. My both cards are undervolted to 1.087v
My question why one of them dead and the other isnt. And the dead one is the 69degree one. The other runs 84 degree and does not die. https://i.imgur.com/7Hx0nPU.jpg my rig: 750w 80 plus corsair gold psu 2 x R9 280x undervolted 1.087 http://www.gigabyte.com/products/product-page.aspx?pid=4845#sp (http://www.gigabyte.com/products/product-page.aspx?pid=4845#sp) Intel core 2 duo e4400 2.0ghz 4gbram.

Title: Re: 1 gpu always DEAD overnight Post by: Lethn on January 03, 2014, 07:58:27 AM If you could give the exact model of the graphics card that would help, but to me 750Watts running graphics two graphics card at full ( which is what any kind of crypto mining does ) is the bare minimum for your energy requirements, it may be shutting off one down so that you can keep the other running.
It would be baffling if you were running low end/mid range graphics cards but high end graphics cards would explain your problem, I have a high end graphics card ( ATI Radeon 6970 MSI Lightning ) running all night and periodically in the day and I have had no problems with a 700 odd watt power supply.

Concur. Your cards are pulling approx 600w collectively, leaving the rest to power your mobo and fans, which isn't enough quite frankly. |
