Title: looking for some help with a rig Post by: cartmen180 on May 03, 2012, 12:30:21 AM Hey there,
I am interested in setting up around 50 rigs. Now i have a good friend who is really into mining himself and has a couple of machines running aswell. Unfortunately he has no knowledge of linux and i was planning to run the maximum amount of gpus on one machine as possible, to maximize profits :) The gpus i am thinking about are the 7970, they are easy to get and have a decent ratio. But to get back on topic, i don't have linux knowledge either. Is it hard to set up a rig with 6+ gpus without prior knowledge of linux? Lets get to the hardware aspect. I was thinking about an open frame. That can hold 6+ gpus (and since it are 7970's i would need two 1200 watt power supplies? or would 2x 1000 watt also suffice?) Further I will need components that are easy to obtain (making it uniform makes it lots easier to maintain). I have seen motherboards with 6 or 7 pci-e 16 slots, but i noticed all pci-e slots can be used? So, anyone knows a motherboard with 6+ pci-e slots thats easy to obtain and of good quality? (maybe even 8 slots?) also which 7970 would you guys advice? i was thinking about the one from sapphire, but maybe you people know something better? thxn for the help :D edit: I just noticed there are FPGAs that run on very little electricity but deliver great Mhash. Is it better to get those? Title: Re: looking for some help with a rig Post by: Lethos on May 03, 2012, 07:37:14 AM If you looking to do a huge investment. There comes huge benefits from going with FPGA's.
Yes the primary benefit is of course tiny electrical costs in comparison to a full system. For many this could mean 10-20x lower electricity bills or more, when you take into account the system it self and cooling. Also it be a huge space saver as well, also heat and noise. I know if I was considered a huge rig deployment it would be FPGA's. The options right now are a bit limited, and usually they are all custom ordered with a long wait period but it's worth it by all those use them. Concerning power supplies, I'm more bothered by their efficiency rating. Usually a 1200W will be better. Having designed and a built a few servers in my time, It's best to go big here. Concerning Linux, it is scary to the inexperienced but, their is pre-built linux setups like BAMT, which are completely designed for nothing else but as a bit mining OS with all you needing to do is input the final details.

If you go with the 7970s, you could still sell them to gamers. Title: Re: looking for some help with a rig Post by: btcnode on May 05, 2012, 05:25:06 PM If you looking to do a huge investment.
