Title: quad 7970 mining rig - mobo Post by: spikyface on June 11, 2013, 11:13:53 PM http://www.coinminingrigs.com/quad-7970-mining-rig/
So I'm planning to put together this rig with four 7970s But one thing bugs me about this build, maybe I'm missing something here, but the motherboard seems way too cheap considering the other components in there Normally I don't skimp on motherboards in a system build because it's limitations determine the upgradability and useful life of a machine Or is there no advantage to using a better motherboard for mining? Like if you got this one: http://www.ebuyer.com/393530-asus-sabertooth-990fx-r2-0-socket-am3-8-channel-audio-atx-motherboard-sabertooth-990fx-r2-0 It's capable of running PCIe 2.0 x16/x8/x8/x4 Whereas the ASRock mobo from the guide is only capable of running PCIe 2.0 x8/x8/x4/x1 http://www.amazon.com/dp/B0058HUQJ0 Wouldn't that make a difference in GPU intensive activities like mining?

I have no problem with the risers, as I understand it, the powered ones are from 1x -> 16x PCI-e so I plan to get four of those (one for each card) That's not my question but it looks like he answered it in a comment anyway: Quote I just want to make sure if the 1x to 16x Powered Riser Cables dont diminish the hashing rate of the cards connected to them? I suppose they dont but just want to make sure Quote No, the 1x slots have no effect on hash rates. The full 16x bandwidth is needed if you are using the card for video games.

The difficulty has more than doubled since then, and it is likely to be 2.5 times as high within a week.

For bitcoin mining is useless , asic miners are here.

For bitcoin mining is useless , asic miners are here. no not really. you could just get a asic and convert with BTC-E to LTC and still be vastly more profitable then a gpu rig. so there is no difference between mining bitcoin or litecoin at the moment.
