Title: Tutorial: how to build a mining rig with 3-5 280x cards Post by: TheSmo on February 14, 2014, 11:53:01 PM Today most of my hardware arrived *happy*.
Thanks to all on this forum who helped with their experience and input. I hope to get the rig running tomorrow and will make a detailed list of my learning. http://www.das-hilfe-portal.de/wp-content/uploads/2014/02/DSC01872-1280.jpg Detailed list of components: http://www.das-hilfe-portal.de/technik/mining-rig-5x-r9-280x-7970-amd-ati/ Title: Re: Tutorial: how to build a mining rig with 3-5 280x cards Post by: TheSmo on February 14, 2014, 11:54:01 PM [reserved]

Also, since the H81 Pro motherboard already come with 2 supplementary Molex for PCI-E, why did you get powered risers?
Title: Re: Tutorial: how to build a mining rig with 3-5 280x cards Post by: TheSmo on February 15, 2014, 12:38:41 AM I bought powered risers in case i need them.As the blog says, this is my first rig ever, so I am learning by doing.
About your first question: nothing is built together yet, will happen tomorrow.

About your first question: nothing is built together yet, will happen tomorrow. I've heard of cheap powered risers catching fire when both the motherboard and riser have Molex plugged into them.

I leanred how to switch on a mining rig without a power-switch... feels like short-circuiting a car :). Next step is a test in a plastic crate... later today. http://www.bombrats.com/forum/index.php?action=dlattach;topic=9876.0;attach=12146;image Title: Re: Tutorial: how to build a mining rig with 3-5 280x cards Post by: wwzoon on February 16, 2014, 04:11:32 PM sorry but i hear that r9 280x like your with undervolt use only 275w, i think that use something like 300 or more watt! i have the same r9 280x :P

They have saved me a ton of effort!

They have saved me a ton of effort! Thanks for the hint, but I changed the BIOS, so when I switch on the PSU, it also starts the computer. More to come.

4 out of 5 riser cables were broken. Had to get replacement from different merchant. Replaced one 280x DUAL with 280x TOXIC. Added a second PSU. Runs non-stop since a few days.
