750Mh/s Ethereum Mining Setup.... In my bedroom :)
When you live in a one-bedroom apartment, there's only one place for the ethereum mining rigs. The bedroom! 4 rigs, along the right wall. A total of 24 video cards, 3 rigs have NVIDIA GTX 1070's pulling 200Mh/s each and the last one has AMD RX 570's that only pull about 150Mh/s. The room is 82 degrees F with everything running and the air conditioning on full blast. A total of 750Mh/s. Not paying the rent yet, but maybe if I cram a couple more cards in each rig.... I should be able to hit 1Gh/s.

I just ordered one of these PCIe expanders. I'm going to see if I can get a total of 8 or 9 cards into one of these cases with just a single 1000 watt power supply.

During the process I'll re-build the whole rig and take pictures all the way. I prefer to take pictures and write instructions rather than do a video.... just my style I guess.
Nice man sweet setup, and one hell of a view!
Thanks. Yeah, a rental on Roosevelt Island in New York City.
Sweet! Will do! :D
where are you getting your gpu's at? They are sooo expensive anymore, have you gotten ROI yet?
Back in June I checked online and had to physically go to a handful of BestBuy retail stores in New York City and bought 14 GTX 1070 Founders Edition cards at the retail price of $399 + tax. I bought the last 4 GTX 1070s off of Ebay for prices ranging from $350 to $500. I got one RX 570 at NewEgg for $226 by watching this page: https://www.zoolert.com/computers/videocards/ . I bought the rest of the AMD cards off of Ebay for between $320 and $360. I actually wish I had just gone with all GTX 1070 Founders cards, they are the best in my opinion and worth every penny of the premium over the AMD cards.
In terms of ROI, it's been nowhere near what all the mining calculators were showing last June, but I'm making a tidy profit. I haven't seen my first big electric bill yet, but hopefully it won't be too far north of $500. I get a payout of $0.05 ether about every 6 hours. This works out to about 0.2 ether per day.... or about 6 ether per month.... So I'm clearing about $1000 a month in profit. It will take me a year just to pay off the equipment.....I'm hoping the price of ethereum will double and make this all worth while.
Yes, that's the goal. I started looking into 1060's actually. I realize you make less, but the effciency is surprisingly better in terms of electricity. As far as I see, we are late to the game, but it's not quite halftime yet. We can still make some money.
Obviously we won't be filthy stinking rich as the guys who got in 3 years ago, or even 6 if they were really lucky.
But we can still get some returns.
1060's are between 200-250 if you wait and buy on amazon or newegg. All the GPU's are gone in bestbuy last time i checked...
Yeah, I'm all about density I guess. I'd like to get 8 cards per rig going. I've got a couple of M.2 to PCIe adapters I'd like to try out..... just need to grab some sata to m.2 adapters to move the hard drives over... and of course get some more video cards.... I run my GTX 1070's at 70% power using MSI Afterburner. My 6 card NVIDIA rigs only pull about 650 watts each.
All 4 rigs actually were more than the single 2400 watt circuit in my bedroom could handle, so I bought one of these to split some power off the 240V circuit that powers the air conditioner.

I would be happy to update this post with excruciating detail, but I'm not sure anyone is actually interested :D
I actually am haha.
I'm a tax accountant by trade, but by getting into this, I've more or less taken a crash course in computers. I mean, I don't know much, but if you asked me 3 months ago what a GPU was I would have no idea...
I'm looking to start coding as well. I have a certification exam coming up for accounting, but after its over I'm diving right in and will probably continue until february (that month, and the week of the 15th of April, are my hell time, so much work I want to shoot myself. The last day is always fun...)
But enough about me. I'd be interested in see what your's looks like. Also, if you have any guides that too. I'm thinking about making a plywood open-air case. but well see...
Interesting. I'm a software engineer. I've worked in finance in the metro NYC area for the last 22 years. I repaired computers professionally full-time when I attended university nearly 30 years ago. I could build a computer from parts with my eyes closed ever since. I built these 4 rigs in about a week, having never built a mining rig before.
I can't believe people put $3k worth of new computer equipment into open air setups. Buy a case for crying out loud. I use the Rosewill Thor V2 cases. They run about $130 from Newegg and come with 4 fans.
I'll put together another post with tons of detail on how to build a kickass rig. Stay tuned.
