USB is plenty fast enough for bitcoin, it's just that lots of writes are the achilles heel of usb flash storage.

Cpu mining would be fine to make sure everything's running fine before your asics arrive - as long as you don't mind waiting a few days to get a single share.

If you're doing this over a local network why not just copy the blockchain from the other computer on your network that already has it?

Re: Bitcoin client upload saturating my DSL connection. (No bandwidth throttling ?)

Just disable upnp and/or stop forwarding the bitcoin port from your router, this limits you just listening to 8 connections.
Currently I leave the client closed and when I want to make a transaction it take as little as 2 min to catch up.  I prefer to broadcast my transaction to 60+ connection than 8.

Given how trivial to implement is what I ask please stop the OS / router patches recommendation . Thank you.

You can tell bitcoin-qt to not use upnp from within the gui, also I don't see how 60 connections is better to broadcast a transaction v 8 connections, using only 8 also increases anonymity.  You can also tell bitcoin-qt to use a tor proxy from within the gui.

I bought a 5770 7 weeks ago that paid for itself in 6weeks(not counting electricity), I just sold it because I'm moving xcountry so ended up with a 100% return on investment.  Your numbers are good I believe, and 5xxx cards are a good choice so go for it. 
disclaimer: I started mining just as the price started spiking and my pool had a long streak of good luck so don't expect as large of a return as I had.

You don't need to make back all the money you pay for the card, just think of it as getting an awesome gaming card for cheap.

Not a fan of putting more hoops infront of small startups. The more hoops you put in front of them the more the forces of corruption will be aimed at Nefario, then the whole system could be comprimised.

Re: Weekly loss of N% guaranteed - Enjoy perpetual loss with fixed Mh/s mining turds
by

Eskimobob, wealth isn't however much of currency N you hold, it's how much real stuff you can buy with currency N.  If you believe wealth is whatever some numbers on a computer somewhere says instead of the amount of real stuff you have bankers are gonna own your ass bitcoin or no bitcoin.

I do not recall arguing against it. Buy miningturds (fixed Mh/s perpetual "bonds")  and it's guaranteed, that every month you can buy less crap with your coin (what ever currency) if you cash in your "investment". 
If some of you still think that miningturds are a good investment, please use simple calculations and actual data from GLBSE to confirm, what so many have told in this thread - your dividends will not cover your loss of principal even if BTC:USD price improves over time. You are better off sitting in BTC.
How hard is it to understand this?
If you have difficulty understanding 1+1-3=-1, please go play somewhere else Smiley
 
 

Yes it's possible just holding btc could be more profitable(and it has been over the last few months), but it's also more risky because if the price falls by 50% your wealth falls by 50% where as holding mining bonds you would be better protected in such a situation.  Basically the reason you think mining bonds are turds is because you could put your wealth into something riskier and potentially profit even more - well duh but you're forgetting you could also lose a lot more if things go south too.

Lol are you joking or what? You pay for that connection, you better use it, or you want to give your ISP money for free? "Here ISP, take my money and don't worry i won't use my connection, i promise!  Shocked

They emailing you?  Shocked

I got one email suggesting there might be malware on my internal network to account for the "over-usage" but nothing more then saying hey your higher then the average person, and I could give 2 shits if they think I am being excessive and I don't care that I upped that much I just thought it was excessive and wanted explanation  .... and my mother-in-law lives with us and netflix is her entertainment so I can't have the cable modem being saturated on the upstream all the time.

If you don't forward the bitcoin port from your router or disable upnp in your bitcoind you'll only be able to make outgoing connections to the network, that will stop bitcoind from using any real upload bandwidth (except when someone in the p2pool network finds a block which is only about 3x/day).

Do you know someone in the service area who will let you piggy back of their internet through wifi?  If you could get that going(could probably be done with less than 200$ hardware) you'd basically have your own dsl connection.

Re: Unofficial "High MHash"/"Best Settings" GPU Comparision Thread
by
racerguy
on 24/08/2012, 15:08:30 UTC
Card Manufacturer: ATI Sapphire
Card Model Number: 5830 Extreme 1gb
Card OEM:
MHash per Second: 279
Core Clock: 925
Memory Clock: 180
Average Operating Temperature: 68 °C
Ambient Temperature: 30 °C
Fan Speed: 20%
Host OS: Win7 - 64bit extreme
Driver Version: catalyst suite (minimal installation) 11.11
Mining Program: cgminer 2.6.5
Command Line Flags/GUIminer Settings: -k diablo, worksize: 256, vectors: 1, intensity: 9, gpu-threads: 2
Other Information: 4 cards, seperated by 1x-16x pcie riser, without plastic on the fans. sempron 140 (unlocked to athlon II X2 4400e) and some 900watt psu. GPU vddc 1.065 V

Anyone could tell me why my cards only run around 279? I tried bamt with phoenix, it gave me about 300mh/s on same settings. Phoenix on win7 will give me like 850-900 only (maybe because i cant overclock properly). Any other kernel performs worse (using diablo).

Please anyone?

Experiment with different driver versions?  I thought catalyst 10.6 were meant to be best for 5xxx cards.  Also you're not having problems with the 100% cpu bug are you?

fwiw my guess is the 7970 is much easier to cool as a 5970 seeing as it's a single gpu card.

Sell your nvidia and replace it with a similar spec'd amd card, should get some profit from gpumining that way.  Some people say they have driver problems with ati cards and gaming, never had those problems myself but the games I play are over 4 years old so maybe that's it?
