Get at least the dual-core Sempron 180 or 190. Please stop suggesting underpowered CPUs for the sake of $5 on a $2000 rig. They can't handle well some work validations (e.g maxcoin), fast scrypt coins, high intensity, CGWatcher, teamviewer, and whatever else a rig operator needs. Not to speak of more rejects and stales (not sure here) CPU is already bought, here, and installed. Vishera quad core, I like to over build a little. That doesn't help on my PSU problem though.... Sorry, I can't help here. I stay away from 2 PSUs mixed with risers (of variable quality), even more because I have access to relatively inexpensive 1050W and EVGA Supernova 1300W which suffices for me. There are some forum members way more experienced than myself. |

The biggest threat to BTC is the 51% attack, as huge corporations and very rich people already have tons of high tech computers mining Bitcoin everyday, the threat of a 51% attack is not that far in the future. That is the ultimate fail for Bitcoin, as new better alt coins will take up the lead.
Bitcoin serves no real purpose in Real Life, 10 minute block time is extremely impractical, that's why many Real life business don't accept bitcoin for small purchases.
Bitcoin's main job is a means of investment, with only 245k people worldwide having at least 1 bitcoin in their wallet.
Bitcoin is very vulnerable, especially to a 51% attack, compared with other Alt coins
Bitcoin has had a 6 year start, or rather 2 and a half year start compared to other alt coins such as Litecoin etc etc
Bitcoin's price can fluctuate unknowingly/uncontrollable such as when it dropped from over 600 usd to under 300 usd in a matter of hours on Mt.Gox. That's also a reason real world business Do Not Accept Bitcoin as a means of payment(They don't want you to spend 1 bitcoin buying a laptop worth 700 usd for example, and the price of bitcoins crashes the next day to under 200 usd, that'll mean they lost over 500 usd)
OVERALL DIAGNOSIS: Bitcoin is doomed to fail...soon (anyone saying otherwise is either 1) Investing their money in Bitcoin, an admirable short term way to make money with Bitcoins fluctuating prices, from 200usd to over 1k usd in a few hours sometimes such as in November.. or 2) Delusional.)
Open your eyes, new better Alt coins are being thought of are worked on everyday, they are the future of virtual currency, Not Bitcoin.
When speculators enter the alt market for their trades, they convert their fiat into... Doge...Nxt...MaxCoin...Litecoin...Vertcoin...HBN? No, Bitcoin. Bitcoin is the gateway to the rest. Oh, and if Bitcoin price falls, that's an easier entry for people with fiat! If my same 1000€ or Goldman Sachs $1B buys more BTC, that means more alts, more flexibility and volatility, higher chances of profit! "My", so to speak, because I don't speculate with fiat. If Bitcoin fails, other coins can't stand on their feet alone. As said before, nobody needs n-confirmations for a cup of coffee. I got some PC games and didn't need confirms. Small items do not need them!. Regarding the 51% attack, it's not needed. All it takes is being banned/criminalized by law, a SWAT team to force who's-who in Bitcoin to make destructive changes at gunpoint, or hacking whatever distributes Bitcoin software. The day it happens, you will be worried with much more than cryptos either way. Edit: nowhere I'm suggesting anyone to hold all your crypto-money in BTC, that's just my opinion. Be careful  |

People with Sempron 145 single-core (and Windows ?) tend to have problems.
Take a look at CPU usage of the miner with high intensities, with Process Explorer.
I can pick higher intensities than most on the dual-core Sempron 190 and even higher on a FX-6100. If you're mining fast coins or non-scrypt, it can be "interesting".

It depends on the particular coin you're mining, and the % of hashrate of that pool vs the total for that coin.
On coins that have avg block time of 30seconds and a pool has a large percentage of hash, it will find blocks quickly and so you will get "unconfirmed" coins in 2 or 3 minutes.
On the other extreme, on an unlucky pool it can take a long long time. High variance is very annoying, yes.

Congratulations for your new rig. Wow, 6 GPUs. ]
"gpu-engine" : "1135",
"gpu-memclock" : "1500",
There is no "gpu-vddc" mentioned. How did you undervolt then? If you haven't undervolted yet, that is a major source of massive energy savings. While I discovered how to do it, I documented it all in this thread; may it help you, too: https://bitcointalk.org/index.php?topic=395004  i did not undervolt since i intended from the begining to overclock. You are going to destroy those cards in no time. |

looked for CraPE (Win8.1PE) in google, went to what i thought was developers page and ended up with malware
Don't think i'll try that again
tried using two montors but will get a hdmi cable and try
thanks
It's in this same forum! https://bitcointalk.org/index.php?topic=247537.0 |

i would say convert your coins to NXT.
Of course you would. OP, I'm not a speculator, so I have an hard time advising you. However be careful with "coin shills". They abound in Nxt and Doge, they are prevalent in a few others. Perhaps, the other advise is fine: 50% on BTC, 50% on alts. Or other distribution, 70% BTC, 30% alts, etc... Nobody forces you to keep exactly the alts you hold now, though. You can always sell them all and buy other set of alt coins with part of the total BTC. Including even Nxt and Doge, not saying otherwise, but perhaps learn some context and understand if it's the best for YOU. Be careful if you end up holding coins that have no volume or have low network hash. They can be unlisted from exchanges or otoh can be 51% attacked and forked. |

Stop wasting your time. 14.1 are bad for mining.
Furthermore, in coin mining, you don't upgrade to the "latest" drivers. You pick and stick with the ones that give you highest hashrate. They work, you stick with them.
Catalyst 13.12 are good.

If you're upset that Dogecoin or any of the others are taking the spotlight away from Bitcoin, you're taking this whole thing too seriously. Y'all just need to lighten the fuck up. This board is read by everyone, including the media. When media people who are looking to smear Bitcoin and the cryptos come in here, they'll say "These idiots can't even have a civil conversation amongst themselves." Next thing you know, there'll be an article in Forbes: "Infighting Killing Bitcoin," and it'll be your fault. So stop being children. Stop arguing the same tired unoriginal arguments we've heard for years. Before it was Doge, we heard the same thing about Litecoin. It was stupid then. It's stupid now. Not to derail your point, but Forbes is simultaneously too uptight and too pathetically biased to be taken seriously by 95% of the world population. Oh, I read they got hacked and 1M+ accounts were leaked. My account data at Forbes was stolen. My Bitcoins are yet in my wallet. That said, the day such an "Infighting killing Bitcoin" article appears on AP or Reuters because of alt-coins, I suspect it's the day alt-coins are gone from this forum. |

You don't need "lots". I have a mining rig that boots from a 30GB usb pen with Windows 7 64bits and many utilities installed. I have 2 wallets open and there are still 16 GB free.

has anyone herd of a mobo that just could not run a video card that's what i'm wandering
Yes, some have claimed that mobos have influence. I'm yet to see solid evidence, but otoh I see it as a possible. Disable Windows Desktop acceleration and effects, themes, etc... You could also boot CraPE (Win8.1PE) or SMOS(Linux) from a usb pendrive. if you boot from a usb does that remove the drivers from the picture ? some stats from gpu-z core 1050 memory 1400 temp 40c (while mining) load 96% thanks Those installations come already with "known good" drivers for mining, at the time they were released. I'm not sure they recognize R9-270's, though. |

If this is (on both sides of the discussion) what you want to contribute to this forum, then be advised that most alts will die the day BTCtalk admins get fed up of so much garbage.

The high unexchanged is fairly common. People ask about it every week.
I've been on Middlecoin continuous since last summer, and beta tested them with another address earlier in 2013. Others pools have popped up on occasion and I've tried most of them. Only Hashcows came close to matching Middlecoin's rate of payout averaged over a long span of time, but they haven't been the same since their holiday hack.
None of the other pools have Middlecoin's primary strength: H20dyssey's ability to sell coins when no one else can at a price no one can match. He manually trades like a hedgefund manager instead of just relying on Autotrade. High unexchanged is an artifact of this.
Biggest example was during the Doge craze during the winter holidays. He jumped on Doge 4 days before any other pool did, then waited to sell until Cryptsy locked up with Doge exchange issues. Hashcows and direct Doge miners couldn't sell on their favored exchange. People were clamoring to buy but couldn't. H20 sold and we made a killing. That's what your 3.88% or so fee goes to. Well worth it.
So don't worry about these high unexchanged values. I love it when they get high, because at the end of the day, we get a bigger payout than if we just autosold everything like all the other multi pools out there during a market downtrend.
BTW- this isn't even close to the highest unexchanged values we've seen.
People should read this before complaining itt. That's exactly how Middlecoin should remain, crappy website, barely no contact from h2o, and all that. He has better things to do than socializing online; for socializing I bet the man prefers his family and RL friends than noisy, low hash malcontents. Please, please go elsewhere if you don't like this pool, or you like cute graphics or "build communities". Leave more server resources and less stales for the rest of us. |

It's not easy. Most manufacturers won't give warranty to the 2nd owner or if the cards have more than 2 years. XFX had lifetime in some items.
I suggest you don't go "all in" on 6950's anyway. I have an ASUS 6950 doing great, while I managed to burn a Gigabyte. You will burn the Rams or VRMs in the Summer operating at 550Kh/s which requires 1.175V and ~1Ghz core. In practice they only reach ~500 Kh/s at 915Mhz, 1.1V and are power hungry (almost twice) when compared with new R9-270's like the Gigabyte R9-270 OC or Sapphires. That means more cost on PSUs and power each month. The R9-280 and R7-265 are coming, so are new Nvidias that may suck less for mining. Even if they aren't the best, this alleviates the price of ATI's somewhat.
Thanks I like your reply very much but this is the most important question: Because of the fact that they cant know you bought it used what should i ask the used card seller for so i can "prove" the company I owned it all the time? (receipt or what?) Yes, get the receipts and check the purchase date. Then you need to go to mfgs websites and learn about their warranty. There are however other reasons why you should consider negociating a lower price per card, or buy just a few handpicked cards, or even ignore the deal. If those are mining cards, (for me) there's an huge difference in remaining value of card running at high voltage vs low. Where does those 550 Kh/s come from? If this comes from 6950 cards flashed to 6970, perhaps the core worked at 1.175V and rams were also overvolted, which can lead to artifacts and damage. Then, there is miner software that doesn't pick 6950 cards, for example Memorycoin and Protoshares (?). With the incoming scrypt Asics, you need well supported, flexible cards that work with all other coins released now and in the future. When Maxcoin was (is?) the most profitable coin, I got 200 Mh/s on the 6950 and 230+ Mh/s on R9-270 and 7870 cards, with way lower voltage and power consumption. $150 isn't such a good deal. 24/7, sustained 550 Kh/s is not possible in practice and it's actually a sign of abuse. The cards are less flexible than new Gigabyte R9-270 OC, or some Sapphires, or perhaps other brands. I have Gigabytes, I'm happy with them vs 6950, not vs 280x or 7950's, of course. I have nothing else to say, as I don't know more or remember. Please don't send PMs for stuff like this, as I tend to ignore them. |

Bitcoin will eventually die.. Once the 21 million bitcoins are produced, the price will skyrocket, once it skyrockets, only a handful few would actually be able to invest in Bitcoin. I don't see Bitcoin having much of a future, after say 2018 or so.. Another Alt-coin with an actual purpose, such as being able to use it buy to groceries or a videogame in real life at a store will take the lead...Open up your eyes guys.
Bitcoins primary purpose is being AN INVESTMENT. (It's 10 minute block time makes it highly impractical to be used to buy, say clothes at a retail store, or coffee at starbucks....)
Other alt coins will become number 1 when they have actual real world purposes.
This is nonsense. I bought the HumbleBundle with BTC and got it right away. Nobody needs to wait n-confirmations for a coffee at Starbucks, and otoh people want very strong security for large transfers. |

@newbies and whiners: in the long term, this seems the best pool. Of course, there are days that other pools beat MC. Nothing forces you to stay here everyday, though.
That said, most-profitable pools popping up like mushrooms are destroying value for everyone. So are the scrypt ASICs.

Can you still switch that card for a Gigabyte R9-270 OC? XFX are problematic for scrypt mining.
What do you get on Gpu-z "Sensors" tab? Is the card too hot and throttling? Go to the PC bios and disable everything you don't need for mining.
