When I see promoting power usage and no price, it either means stratospheric price or crap performance  So, how much does it cost? $200 - 300? |

The only disadvantage that I see is lack of density for "serious" miners. Too much room used by cards that net you less. Then the fixed costs of a base system, related with the hashrate each rig offers.
I don't see 125W pulling 450 Kh/s, more like 150W.
But there are upsides, of course. You can run a 5 card rig with a single 1050W or 1200W PSU, you may offload the cards for a bit more (people refrain from paying too much for used cards, but $100 per card is easy), you lose less hash per failure, etc...
I'm going down that route and get one tomorrow for testing, hopefully. If they give 450+ Kh/s, I'll probably order a few more

I currently have x2 270's and x2 280s' and x1 290. Given that you can buy a 270 for ~200 that can do 450Kh/s and is 125 watt. I was thinking that we are better off with 2 450+Kh/s for $400 than 1 280 that does 750KH/s and pulls 250 watts. Anyone have any thoughts?
I'm confused, hopefully someone can help me. My Bitminter says I'm running at 8825 khps with a crappy old GT 420 graphics card. (nvidia) When I see a new card that runs at 750kh/s it looks to me like the crap one I'm running is faster. I know I'm definitely missing something here. What is it? You are mining bitcoins, and your hash rate is "worth" 1000x less than what is being discussed here. Different coins have different and arbitrary hashrates. The major coins with different algorithms are Bitcoin - SHA2, LiteCoin - scrypt, PrimeCoin, Quark, Protoshares. There are a few more that I don't easily remember You should use the cudaminer software (there's a discussion thread here in this forum) and mine scrypt or, it seems scrypt-jane based coins |

I don't see a good future if everyone and their doge start pulling money out of thin air like this. Pandora's Box comes to mind again and again. I'm afraid of hyper-inflation and worse in a few years from now

Don't waste time arguing.
There are lawsuits going on against BFL. Join them.

^^^^ not for BTC withdrawals.....
craptsy don't have fiat.
Sure, but still... Then, once or twice I've been transferring alt-coins in the midst of a 51% attack or with low network hash because it's not the most profitable anymore. I can't blame the exchange for lost or unconfirmed coins. In fact, I have some GLD unconfirmed for more than a month now, when it forked or a bug was "fixed" or whatever. Except if an exchange is scamming/stealing, I have some tolerance for their problems |

I just love those users who are "giving advice" without knowing anything about how tahiti xt works on scrypt coins. Just hilarious.  The very basics: Undervolting does not increase hash rate. Power tune only limits maximum TDP. Its not some miracle tool. If TDP reaches the limit then card will automatically downclock itself. Every card has slightly different sweetspot for VDDC vs GPU clock. Need to test it out. If card runs less hashes than expected on certain clock rate then its very likely running too close to limits. Dowclocking or VDDC increasing will help. Good settings are available on LTC mining hardware comparsion WIKI. You're not very good either. best mining settings (as in hashrate and hashrate/W) can be dependent on temperature, VRM quality, voltage, core ASIC quality, ram mfg, ram timings, bios version, bios tables, bios modding, OS type, OS version, drivers, motherboard, PSU output, etc... Specially the way ram timings are set by the bios, whose you cannot mod |

So, the majority of you believe that 250 years of industrial revolution, human activity and de-forestation have no impact on climate?
No. I don't believe in that easy strawman. Your point is "If you do not share our view, if you do not believe in global warming made by humans EXCLUSIVELY, you are a baby polar bear killer, roasting their brain with woods from the Amazon, and you called your first born Adolf", or something.... You don't know what my points really are itt... One is: why do people even try to come with apparently "high-minded" arguments to mask and hide their basic self-interest, in what often is a zero-sum game? In my view, neither camp has much credibility, due to the conflict of interest involved. 2ºC hotter or 2ºC colder, means loss for some people and gains for others. So is reducing the dependency of oil. In the U.S., this drama has to do with keeping the domestic oil industry and the petrodollar. In other regions, like Russia it's gas, oil, more arable land and access to Artic. In Europe, there's North winter/South summer divide, i.e. nobody wants colder winters and paralysis at North, while Southerners can't stand hotter summer and droughts. Global warming for already hot regions like Africa and Middle East is terrible, etc... But it is not a zero-sum game. Billions are "invested" everyday in the fight for global warming and climate change. Crony capitalism and politicians who love taxing LOVE global warming. So it does matter to them to make sure by imposing a carbon tax they will reduce the temperature by 2ºC in 200 years, if you pay now to help for their reelection, for the funding of his friends' research for the next 20 years, etc, etc. Of course the flip side is "Yes but you forget Exxon is paying for EVERY single denier's research. The dogma is settled and those poor souls can't seem to find the light, blinded by the factory smokestacks of their evil masters..." Sorry if i did not know what your point was. I reply to an idea, not really to individuals. You're probably right regarding attempts to taxing, yes. That doesn't invalidate the problem that humanity is indeed turning the planet into a toxic, lifeless shithole. Based on these facts, it is not absurd to think that climate change has a very strong human component. That opportunists take advantage and ride this bandwagon to push for taxes, is therefore a side point. otoh I don't know what Exxon did, but my previous post still stands. It's far from a dogma or conspiracy to admit that oil industry, countries, and those politicians/elites you mention, shill according to their best interest. The ones you oppose arent worse than the ones you defend. |

I tend to think that wireless spy chips becoming standard in PCs is somewhat relevant to Bitcoin.
It is very relevant. Out-of-band access can bypass all security precautions, even an offline machine with a wallet running Tails OS. Out-of-band access has been available to anyone who is interested since the mid 80's. Off the shelf equipment like the DataScan 2 from Codex allows anyone to observe your activities from a mile away. Governments have protocols to prevent such emanations, to prevent remote observation and collection of sensitive data by unauthorized individuals (I assume you are concerned about someone obtaining your private keys?). Tempest shielding was popular in the 90's to protect against spying. Red/Black separation with optical network connections are used to prevent electromagnetic inductance from secure computers leaking sensitive information. This is very standard in most military installations the world over. What you need to understand is the attack surface is massive, you make no attempt to filter the signals leaving your computer through the power lines entering your home, you make no attempt to shield the data being processed by the CPU, what do you think happens when you switch at millions and billions of cycles per second. Everything the CPU processes is transmitted, simple laws of physics, everything. If you are serious about protecting your privacy on your computer, you had better learn about Van Eck Phreaking and Tempest monitoring at the very least. To be clear, I would much prefer discussion about ways to grow the Bitcoin network, new services, and new ways to use Bitcoin. Fun Stuff. If you are concerned with those, use a laptop on battery and "Spread Spectrum" on your PC bios. Don't use it to try to distract from the discussion of NSA and the 3G radio inside Intel processors Furthermore, as an Software Defined Radio entry level enthusiast, I don't really need to "learn" that. I know it. |

i already have a good working windows miner but i don't like windows ...  |

Mining is always at least with open case.
Preferably on open air, PCI-e risers and an household fan blowing at the cards. You can skip one the 3 before IF you seriously undervolt cards and monitor temps, and even then it's not recommended.
The way you're doing it, cards don't last long.

Yeah. Relatively speaking, that is.
Cryptsy can take hours. MtGox can take months.

Coinbase & Cryptsy seem legit and I trust them so far here in USA  I would send you my referral link but I'm not sure if I'm allowed to do that yet here I thought I read the Cryptsy doesn't like people mining directly into their account. Maybe they don't like a bunch of tiny deposits occurring all the time. You can mine to your own wallet and then transfer them in larger lumps. I am still learning though... If they do not like, they should clearly say so. I've been doing micro-deposits and trades since I started mining alts. |

XFX tends to cheap out on vram speed. You risk low hashrate with that brand of videocards, even with modded bios or force-flashed from other brand.
PCI-e and system ram speed don't really matter. I suggest a Sempron 190 dual-core instead of the usual 145 single-core, for extra $5 or so.
I have an UD3 but I'm not sure how many cards it really supports at mining. In some motherboards, sometimes adjacent slots are disabled or otherwise aren't stable.
As PSU, See if an EVGA Supernova or Seasonic have 10 pci-e connectors, perhaps 1300w and above.
Crossfire is detrimental to coin mining.

Use an older version of reaper, cgminer or bfgminer for that GPU and your current cgminer for others

Increase the --gpu-memclock to 1750 or 1800, then increase --gpu-engine accordingly.
--gpu-engine accordingly.  ?? Yes. Start at ~55% of the memory clock, for example --gpu-engine 950 and --gpu-memclock 1750. Then on the cgminer window, press g, select and increase 10 Mhz on [e]ngine. Do this multiple times until the hashrate drops. Go back a bit and then use that value that gives you the best hashrate Then do the same again, but using -I 20 -g 1 --thread-concurrency 24000 |
