50mhash for litecoin... How do people get this much? (Share experience)

[howdoin]

Technically I know how this is possible, with a lot of GPUs and power but seriously... How can people get to that much Ghash on GPUs and not blow up the entire neighborhood with the power consumption - with only a couple system I can blow up fuses in my apt if I plug the vacuum, iron and start the ac at the same time!

Counting quickly, to reach that much hashes you could use 100 ATI 7970 ($400 x 100 = $40.000) just for the cards, then systems and power at 300kwh x 100 is over 30000kwh.

I am amazed at the dedication and possibilities, just can't imagine how people set these up.

Feel free to chime in or share your experience if you have one of those set ups - I'd love to know how you ended up building it.

Few things here:

If I'm buying 100+ cards, I'm not paying retail and the 300kwh per card is a bit high. I also get about 640k/h per 7970 @ stock settings, so it'd only take 80 cards to get to 50m/h

And I'm guessing that most of them either rent space or work somewhere that will let them use the electricity. I sincerely doubt that the people hashing at those rates have all that stuff inside where they live.


It would be cool to see some pics of the larger setups though. I've seen people ask but I've never seen anyone share..

100*.7 mhash/s =70mhash/s not giga hash

i know some guy in my country, they use over 170 7950 (now it can run near 700kh/s)

How can people get to that much Ghash

They don't. The entire LTC network right now is estimated at 8.8GH/s.

Mixed my hashes, corrected.

Here is a video of a guy that has a 25 machine rig. This is what I want
