Also alles kann ich nicht beantworten:

Aber zur Hardware: Dein Plan ist meiner Meinung nach MIST!. Zwei Rechner tag und nacht laufen lassen kostet nur unnötig strom. Kauf dir ein ASRock 880G Extreme3 Mainbaord und pack alle 3 Grafikkarten da drauf. Dazu ein 600 Watt Netzteil mit 80+ Gold zertifizierung (zum. Bsp. das Corsair AX650W, oder besser das Corsair AX70W weils billiger ist). Und ansonste dein Spemron 140 und 2 GIG Ram. Ein 4 GIG USB Stick fürs Ubuntu und du bist fein raus. Festplatte brauchste gar nicht. Ist das Energieeffizienteste.
Gehäuse brauchst du wirklich nicht, wenn du das sicher auf nem Tisch, oder in nem Regal verstaut bekommst.

Zur Sicherheit:

1: Sicher nicht verkehrt
2: Genau
3: Die Leute die ihre Festplatte freigeben sind selber schuld.
4: Dateien umbennen wird nicht gehen, solange du sie benutzen willst. Am besten die wallet.ini mit truecrypt verschlüsseln. Und auf nem USB Stick speichern. Oder besser 2en.

Mining Pool:
1: ich selbst bin bei Slush und zufrieden. Ansonsten sind die kostenlosen auch ne Überlegung wert
2: Guck im Englischen Mining Forum. Der erste Post ist eine Beginner Guide. Da steht ne Liste mit Pools drin. Glaube nicht das da schwarze Schafe dabei sind.

Hehe,

nein das geht so leider nicht. Alle 11 Tage im Schnitt wird die Schwierigkeit neue Bitcoins zu generieren angehoben, und zwar genauso, dass danach wieder 6 Blöcke (also derzeit 6*50Coins) pro Stunde generiert werden. Wenn in diesen 11 Tagen viele Leute in ein System investieren, so fällt der Spring recht groß aus. das können 20% sein, aber auch 80. Und um geanau diesen Wert fällt dein Einkommen. Alle 11 Tage im Schnitt. Da ist es a) nicht möglich zu sagen, wie du in einem monat 1000€ machen willst, und b) schon gar nicht möglich ein System zu bauen, was diesen Wert über Monate hält.

It's the same with the difficulty increases: Lets say we have a run at mining systems now, because of many reports in public channels. What will hapen? Right, the difficulty will double surely within 2 month. That would also result in a halved cashflow. The point is: Bitcoins is no secure buisiness to print money. It's a speculative game. So talking about buisinessplans:
It is the same as investing leaned money in high risk shares. It works as long the share price increases, but collapses if the price do so.
I wouldn't invest leaned money into bitcoins, but i am willing to risk a few hundred dollars now buying mining hardware.
Scenario 1: Bitcoin value rises and rises: I am fine.
Scenario 2: Bitcoin value stagnates: Okay i made a bit money, but no good deal.
Scenario 3: Bitcoin fails: I lost a few Dollars when selling the used hardware for a lower price.


But with credits, you could loose your whole exisitence.

Die einzige Variable die für die Rechnungen gebraucht wird ist die GPU Power. Genauer gesagt ist die Anzahl der Stream Prozessoren entscheidend. HD5870: 1600 Stream Prozessoren. HD6970: 1536 Stream Prozessoren.
Daher ist die 6970 langsamer als die 5870 (was das Mining angeht). Bei Spielen sieht das anders aus.
Was Speicher angeht: Der ist völlig irrelevant. Nicht umsonst takten die ganzen Miner den Speicher ihrer Grakas runter, die GPU jedoch hoch.

I'll one up your user directory of businesses with my browser integration....

How's bitcoin://1234567890addyHere:1.0amount:Comment to have the official client fire bitcoins off on mouseclicks?


Yes, that too Wink We need to get rid of the addresses for normal simple transfers - not in the protocol, but I should not have to copy/paste that. I like the link.

One disadvantage of the protocol is that one can not attach any information to a transaction... which means at the end either people send fancy numbers (pay 2BTC, send 2.00004322) or use one receiving address per client / invoice. The later is nicer, but adds a lot of complexity to the bookkeeping and handling side. This needs to be sorted out.




65 Coins? Is that a housenumber?  How do you get that number? I for myself are mining with a single 5870 Card sind 3 days and got 2,5 coins since now.
Now i am building two mining rigs With around 1,2GH/s each, and I am looking forward to get those online on tuesday evening. That will result in 6 Times the outcome at the current difficulty. So that means 15 Coins in 3 days or 5 Coins a day. I think it will be around 14 days to the next difficulty increase (after the one tomorrow). So i would say: 65 Coins are mined within 3 weeks.

Mathematically your scenario is easy:

Compare two situations:

Pete starts mining in a universe where after one month of his mining, the payouts gets halved. He starts with 1 Coin per Day and within the fist month, he earns 30Coins. In the Second he earns another 15 Points giving him a sum of 45 Coins (excluding all Difficulty increases, which, for the sake of comparability, are the same in both universes).

Jane does the same in a universe where after 2 weeks the payouts were reduced in a way resulting also in a halving of the payouts every month (which would be he squareroot of 0,5, so nearly 0,7)
She gains 15 Points in the first 15 days. Then from the 15th to the 30th day, she gains 10,5 Coins. After the 30th Day starting with month two she has collected 4,5 Coins less than Pete. That trend will continue. So it is better to make clear cuts after long time periods.

Was ich empfehlen kann: Mal die Atelco Märkte in der eigenen Umgebung abgrasen: Die haben oftmals gebrauchte Ware zu schnäppchenpreisen. Und manchmal auch zu Wucherpreisen:

Im hiesigen Atelco Markt gibts 2 5870 und eine 5850. Preise: 120, 149, und 180 Euro. Die HD5870 für 120 ist übrigens verkauft Wink
148  Local / Deutsch (German) / Re: Sapphire HD5850 Xtreme on: June 05, 2011, 10:51:03 AM
huhu,

ich habe ein Ähnliches setup. Hab mir mal 8 5850er bestellt.  4 TWIN FORZR und 4 Sapphires. Da der Rechner im Büro stehen soll, sind die leisen bevorzugt. 4 davon werden eingebaut. Die Karten allein ziehen etwa 600W mit nem Minimalsystem kommen nochmal ca. 50W dazu. Hab ich mit dem Corsair AX 850 noch 200W Luft. das wird es dann wohl auch werden. Wobei das 1200er sicher die bessere Zukunftsperspektive bietet wenn die HD 7XXX Serie den Markt betritt.

LG

149  Bitcoin / Mining / Re: Cheap board and CPU for 3 GPU's? on: June 04, 2011, 09:02:59 PM
Hi there,

a bit more expensive and with 4 Slots:

Gigabyte GA-990FXA-UD3  (AM3+)
ASUS Crosshair IV Extreme (5 PCIE Slots, 4 of them are usable without extenders)
Or if you really want to get it a start: Gigabyte GA-890FXA-UD7  (6 PCIE-Slots!!!) But you would need PCIE Extenders)

If you want to use 4 5870s i think 1000W should be sufficient. I for myself will use a 850W Power suply for 4 8580 Cards (Or perhaps one 5870 with 3 5850 Cards)








150  Bitcoin / Mining / Re: Cheap board and CPU for 3 GPU's? on: June 04, 2011, 08:28:31 PM
Hi,

i would recomend selling your i7 system instead of using it for mining. Any cheap CPU does it. Here my suggestion:

AMD Sempron 140
MSI FX790 GD70 (4 PCI-E 16x slots, I get mine for 50EUR)
Or else: ASRock 880G Extreme3 (3 PCI-E 16x Slots)
Add a cheap Ram Modul and you have the perfect basis for a efficient mining machine.





151  Bitcoin / Mining / Re: How should I mine? on: June 02, 2011, 03:37:41 PM
Hi,

i think it is just preference in which pool you want to anticipate. For the rest: test it: If you get over your 630MHash / sec, then do it, else stay with 630.

152  Bitcoin / Mining / Re: What's your energy rate? on: June 02, 2011, 12:28:43 PM
at home: 0,23EUR per kWh (= around 0,33USD)
at work: 0,00
153  Economy / Marketplace / Re: Buy and Sell Mt Gox USD on: June 02, 2011, 12:07:38 PM
Hello,

i want also to add 150USD to my mtgox account. I am from germany and want to buy some Bitcoins paying with Paypal.
If you are interested, please contact me by PN.

154  Bitcoin / Mining / Re: Mining with multiple machines on: June 01, 2011, 09:50:32 AM
St the moment there aren't so much GPUs which would be used. (ah 5870, a 4870 and a GTX 570), But i know several people who would like to anticipate. So i thought of my own pool. If i see the effort is too big. I drop it. But at least I want to try.
155  Bitcoin / Mining / Re: Mining with multiple machines on: June 01, 2011, 09:16:55 AM
maybe, maybe not. In Fact i want to setup a pool for several people. Perhaps I decide this to be to much work, but i will try at least. It would surely be also a nice opportunity to learn s.th. about the network.
156  Bitcoin / Mining / Re: Mining with multiple machines on: June 01, 2011, 08:45:52 AM
and where can I find Infos regarding to Option 4?
157  Bitcoin / Mining / Re: [Question] HD6970 for 266 EUR or HD6870 for 200 EUR? on: June 01, 2011, 12:05:51 AM
Hello,

i would prefer a Graphic card out of the HD58XX Series for mining. The architecture of the 5000-series is more opitimized for the sort of parallel computing which is needed for mining. And it's also cheaper.
The best MHash/sec per Cost value has, in my honest opinion the 5830, followed by the 5850 and the 5870. I was lucky getting a nearly new 5870 für about 120EUR today at my local dealer. So if you want to have a dedicated mining System: Choose the 5830 perhaps two oder three of them. If you want to game also, then youn would be better off with the 5870 (for the purpose of mining - due to the architectural properties of the 69XX series, these are better optimized for gaming benchmarks, than for parallel computing.
