Title: Dedicated mining rig Mhash/s to $ query Post by: trentzb on April 10, 2011, 01:34:19 AM Electricity and recurring costs aside, would anyone care to share what their Mhash/s per $1 USD dedicated rig investment is? I am curious to learn how diverse (or not) the investments are. I am referring to all hardware aggregate investment into a dedicated rig (or rigs).
Our first couple rigs are at 1.23 Mhash/s per $1 which is a little lower than our goal.

I am curious to learn how diverse (or not) the investments are. I am referring to all hardware aggregate investment into a dedicated rig (or rigs). Our first couple rigs are at 1.23 Mhash/s per $1 which is a little lower than our goal. My first three rigs were just video card investments dropped into scavenged units. An 5870 for $200, so about 1.5 Mhash/s per $1 and a 5830 for $130 similar results. Now I have built my first dedicated box for two HD 5870's when I get them. I spent $75 for the case (will be another story/post!) $47 for the power supply, $90 for a dual slot x16 MB, $39 for a sempron (unlocked to two cores and 3.1ghz), $60 for 4gb ram. All other parts were existing ones I had (dvd/Hd). Assuming I pay $200 for each of the next HD 5870's it will be $1 for 1Mhash/s. At the current rate of difficulty increase this hardware WILL NOT pay for itself or it will take nearly a year. That is ok. When it stops being a net profit it will become my next desktop. I just will let it sleep when it is not in use. :) Title: Re: Dedicated mining rig Mhash/s to $ query Post by: Jaime Frontero on April 10, 2011, 02:34:46 AM I spent $75 for the case (will be another story/post!) $35 for the power supply... yikes! i just cobbled together a similar system (are you using the msi 870A-G54 mobo?) - except 5850s instead of 5870s. but i spent $125 on a cooler master 750W GX PS (and then got a $35 rebate). where did you find something that'll run those cards for 35 bucks? i want one for my next miner...

zalman makes decent stuff. i have a couple of their coolers on my desktop. |
