Title: HELP ME- minin rig hardware Post by: avialias on May 18, 2011, 05:37:21 PM Hi...
Please help me choose hardware for multi GPU mining rig. Rig will be used only for mining, not for other stuff. I have another PC for that. So, I got 4 HD5870s, but I need other hardware , MBOs , CPUs , DDRs, POWER Supply What do you recomend??? For CPUs : AMD athlon II x2 250 yes, no MBOs: need something with 2 x PCIe x16 yes,no Do,the MBO, have to have onboard GPU, or not??? Where do you connect monitor if you dont have on board GPU? POWER: how big do I have to have? more than 800W or more than 1000W What do you use? DO I have to worry about current that goes through a MBO to 2x GPUs? What mining software to use on multi GPU rig? Is it better to be in mining pool or to mine by me self...??? PLEASE HELP fast... I saw https://en.bitcoin.it/wiki/Mining_rig, but I cant buy that stuff at my country...

Where do you connect monitor if you dont have on board GPU? POWER: how big do I have to have? more than 800W or more than 1000W MBO: no PCIe x16 needed for mining, x8 works too. OnBoard GPU is useless, connect monitor to one of your 5870s PSU: for dual-5870 650W will be more than enough, 12V-rail has to handle enough load though (calculate ~200W per GPU and you're good).

What about that 12V rails??? are rail on power supply or on MBOs? sorry i dont understand..please explain...

What about that 12V rails??? are rail on power supply or on MBOs? sorry i dont understand..please explain... PSU of course, check its specs to see how much power can be drawn on its 12V rail(s). as mentioned, for a 2x5870 (<400W) rig a 650W PSU should do fine, i'm running 1x5850 (~150W) + 1x5970 (~300W) on 650W 24/7 for a few months now without any problems.

And how to setup minier and which miner software to use??? Are you mining in pool or alone??? Title: Re: HELP ME- minin rig hardware Post by: BitLex on May 18, 2011, 07:01:20 PM How much Mh/s do you get??? some (that 5850+5970 setup just one of my rigs, i got a few more),you can expect 350++Mhash/s on each of your 5870s, so it's 1.4++Ghash/s on 4 of them Quote And how to setup minier and which miner software to use??? depends on OS, driver/SDK version, and not at least you preferencesQuote Are you mining in pool or alone??? both :Dactually on my own pool, but i'm the only one using it so far.
