What hardware have you been must impressed with/has had least amount off hickup

Guys…you get me really thirsty! I just wish I had a 3 Mh/s rig like one of yours. How much did it cost overally? less than 3k$?
I feel lost now with my poor 5850, OCed barely to 400 kh/s. -

[/quote]my 2400khash (4x7950)rigs cost around 1800$ a pop
my ordered 3000khash (4x7970) ordered rig cost around 2400$.im not satisfied until i exceeds nutnuts hashing power ::)
for people that have money to invest, digital mining is truelly a goldmine.
especially ftc which i do believe will be much more worth in the future. -

[/quote]Lol - good luck, just ordering more rigs! ;)

I don’t know how you guys can afford to do it… I have eight 7950’s running now and the cards alone cost me $3000 Canadian. To say nothing of the mobos, processors, RAM, PSUs, and of course - the electricity. You guys must be independently wealthy already - you hardly need to invest in Feathercoin! ;)

i invested around 4800usd in the beginning
on used cards and such (23 cards og different model, mobo/cpu and so on)this was i february. after two months of smart mining it was all paid of.
i then sold all the used cards and bought 15x7950, with a reinvesting of around 2500-3000$
also did some changed to my main computer with 7970’sim earning around 30-40$ pr day counting todays value and substract power.
it will take me around 3-4 months to pay an ivestment down.
id call that a win/win and i do think that the value will rise.at the end of the day i have alot off kickass hw worth some for repurpose.
and ill make a buck or two:)hmm want to buy more as im speaking…

The $3000 figure for the cards was ‘all in’ (taxes, shipping, the works), I spent another another $1000-$1500 on other sundry hardware for the rigs - but I’m only mining Feathercoin (and now the partmner coins) and I don’t want to sell any of them - certainly not until they have appreciated in value a bit. Electricity around here is billed every two months, and I’ve only been in it around that long so aside from educated estimates I don’t know where I am yet for power costs. To top it, my server room is in my basement and there is only one small window just below ceiling height - depending on the weather outside the ambient temp in that room goes from around 26 degrees C to 33 degrees C. If I have to add cooling (IE: Air conditioning) to the mix that’ll be more expense.
Sigh…

Nutnut i have one of those gigabyte 7970 oc cards. Which settings are you using to get 760khash? Will try on mine and if im able to get that to work i will buy 3 more for an 7970 rig:P

[/quote]I’d like to know how you are handling your electricity to the shed and what your actual current total kW usage and how many amps total are being used.
[/quote]As would I, and probably others. It has been my curiosity since I started mining just how exactly people are getting so much power to run their operations. Knowing that I am pulling consistently 8.3ish amps to get 2.5 Kh/s on my little ol’ 4x7950 rig … I can’t imagine. Of course I am limited to 120 VAC (darn U.S. standard domestic wiring!). Most homes max at 180a total feed, with bigger homes usually at 200a.

When i say “Shed” it’s actually a log cabin (6m x 4m) and was intended to be games room but that never really happened.
In terms of power i have 10mm SWA running from a separate tail from the meter on a 40a breaker at the house which terminates in to another CU in the shed. Then i have a dedicated 32a breaker that feeds a 32a commando socket into the pdu. The house has a 100a/240v supply.
The rigs are pulling 5.9KW/25.9A according to my PDU. It runs @ approx 228v so there’s a bit of voltage drop but that’s to be expected over a 50m cable run.
I’m a card down at the minute so that will increase slightly.

I was only running 19 cards at that point now back up to 20. I also think 1 card went dead in cgminer. It also ramps the power up as it gets hotter (fans working harder).
Here’s the full set running red hot today (summers here at last!!!)
Mine are voltage locked too. No clever trickery here. each rig pulls ~ 1300w from the wall. You are basing that on 240v and not 110v right?

[/quote]There’s no way I’d be able to mine at home. The electricity there blows my speakers every few months, the people who wired the stove originally had it rewired to use a clothes dryer socket/plug, the oven in my stove doesn’t exceed 200° unless I have the fan on in my bathroom…So my rig is currently in the back room of a store at a local mall. I don’t have admin access to the router and they kill the power every night so every morning I have to guess what the local address is through ssh.

… lol… Thanks for sharing lol… I know it’s not funny to you but I can’t help laugh about that fan bit.[/quote]
Oh, it is funny. Just occasionally tragic. Got the poop scared out of me the other day when my 360 wouldn’t boot. Took it to that store and plugged it in and it booted right up, but it was just seized at my house and none of the outlets would work for it. Took it back afterwards and it was fine. Just a bunch of a ridiculous voodoo.
[quote]Not having to pay for electricity is awesome at least.[/quote]
I just wish they didn’t kill the power. Is there anything I need to keep in mind for:
1. Only mining 8 or so hours a day.
2. Abrupt power outages. I have a surge protector that it’s plugged into and the unit reboots and gets right back to work when power is restored, but is there something else I should be providing for?[quote]You can install a client on the machine from dyndns http://free.domain.name and it will point an address to the machine. They have a linux client: http://dyn.com/support/clients/linux/
[/quote]Oh nifty. I’ll give that a crack.
