I'll keep using GPUs over ASIC because of a few reasons.
1) I don't trust any of these companies that are pre-ordering 2) If my ASIC is no longer bringing in many coins, or the hashing power is insignificant because of more powerful ASICs and/or the increasing difficulty, then it is a worthless device that will resell for no-where near what I paid for it 3) If my GPU is no longer bringing in many coins, then I can move to another crypto-currency that is more profitable, if that doesn't work then I can move to another one, if that doesn't work then I can sell it for relatively the same amount that I paid for it. People are always upgrading their computers and these cards are all pretty beasty

Ok I got it now.. What about if I send my email and its password?Or do I have to send a signed a contract saying I will pay?
LOL Apparently, in order to get a loan on here you need to provide your SSN, picture ID, passport, name, address, email/password, a notarized letter of intent, consent for a background check and credit report, AND collateral. Like they said, though. Don't blame the board, blame the scammers before you that had similar stories. I understand all of the concern with this loan as 1.9BTC is a nice sum of money. I do not, however, understand all of the requests for collateral/documents for these 0.05 BTC loan requests. It's five bucks... either trust someone or don't, but who the hell is going to throw up collateral for a few bucks? I guess I'll find out soon enough if I decide to take on a little loan

If I had the BTC, I'd do it. The Steam account is definitely worth the collateral.
Good luck!

This will just make LTC/FTC/etc more difficult to come by.
Huh? All cryptos become easier to come by as they get mined (there is more in circulation). Difficulty adjusts to keep production constant--I don't understand the logic here. I just meant that as more GPU miners leave BTC and flock to the scrypt-mined currencies, then the hashrate of those currencies will increase meaning that a 800-1200KHash rig will not generate as many coins as it does now. So it would obviously not be as profitable (if profitable at all) to mine the scrypt coins depending on how much higher the hashrate climbs, and the value of the coins. So yes, they will be easier to come by, but the relative ease of mining for them with a GPU rig could be exponentially increased depending on how many GPU rigs switch over from BTC to LTC/FTC/etc

Stupid question...
How do I log in again? I made my deposit on my home computer, and then sent the link to my work computer... can I not do that? Will I have to wait until I get home?

Thank you so much for this detailed response! I'm currently mining FTC and LTC. I was mining BTC but the pool I was in (Triplemining) went down and I decided to move on. My electricity cost is pretty insignificant ($0.06/kwh) but I will look into undervolting them if I can get the 3 card set-up to work. I would love to have 3 7950s, but I imagine I will end up getting another 5850 or something that I can find on Craigslist for under $100. I might need to check out one of those fancy multimeters (?) so I can measure my wattage at the wall. If my math is right, 850W running at max for 24 hours a day, would only be $36 at my kwh rate, so I am not too concerned with it since anything over 600MH(or KH)/s should be sufficient to profit. Right now I'm cranking out 700-800KH/s so I am just really trying to get it up to 1+MH/s and then put it in the corner, set up cgwatcher to mine the crap out of it, and then gamble with all of the coins Definitely wouldn't mind getting a 7950 in it though... that would boost the speed significantly. Hmmm... so why was 630W not enough for 2 cards? I guess that's why I am confused. But I hope you are all right because i would love to be able to get another card running and not have to mess with the PSU again There are so many factors it's really hard to say why that setup didn't work out. It's possible that the 12V rail(s) on the 630W were simply not up to the task (PSU wattage does not tell the whole tale). Antec likes to put multiple +12V rails on their PSUs. Each rail has its own OCP (over current protection) and sometimes on the lower wattage PSUs (650 and under) a single rail simply won't provide enough amperage for mining without tripping. This or any number of other things could have been causing your issue. I looked into the Antec 850 that you have and it seems decent. It has four +12V rails which are distributed a little oddly but I doubt will cause you problems. According to this review: http://www.hardwaresecrets.com/article/Antec-TruePower-Quattro-850-W-Power-Supply-Review/555 the OCP for each +12V rail doesn't trigger until 32A (the official rating says 18A). If you decide to try three cards, I'd certainly recommend that you undervolt them if possible to reduce the total load on the PSU and also save on your power bills. The stock voltage setting for cards is usually wastefully high and can safely be backed down a bit to lower temperatures and increase efficiency. It's usually not a good idea to run your PSU at 90%+ of its rated capacity as it greatly reduces the expected lifetime of the PSU. Efficiency and voltage regulation capabilities also drop off sharply around this point. Anyway, I really do believe that your Antec 850 will be enough still, especially if you can undervolt your cards. Also, you never mentioned what you're mining. SHA256 (Bitcoin) mining uses less power than scrypt (Litecoin) mining. I'm currently running 3 7950s on an 850W PSU (XFX PRO850W) without issue. I did undervolt my cards quite a bit though. At the stock voltages of 1.2V on these Sapphire cards, I was easily running at 90%+ of my PSU's capacity mining Litecoin (~900W measured at the wall). By undervolting the cards significantly and lowering the memory clockspeeds, I was able to get the total system power usage down to 620W at the wall. Current setup: 3x 7950s 570Kh/s each, 1,710Kh/s total (scrypt) .985V core 955Mhz core 800Mhz memory 620 watts, measured at wall (via Kill-A-Watt) My hash rate is a bit lower than the numbers often bandied about but since my power costs are fairly high, I've realized that efficiency is more important. My cards will run up to 650Kh/s but the extra power used to get there isn't worth it anyway. With a bit of tweaking, I think that you can make your setup work out as well. As long as you can lower voltages, your 850W will be more than enough. Good luck!

Round complete! Woot woot!

well the 7950 would definately increase your hash rate if yiou have some spare BTC there are occasionally ones in the forum for sale - so far none in teh UK for me though Yeah, my wife told me I could get 3 new cards if I want. I just have to sell my shares of Fannie Mae... Oh well this is just a hobby for me, so I will probably wait to get the 7950, but if I can find another $60 5850 on Craigslist then I will snag that up.

Bump. Any help would be much appreciated!

I guess it depends on what cards you're running - i have a 5870, 5850 and their running happily on a 850 pulling around 430w with some other stuff running (i have 2 ASIC USB miners plugged in) Well I have a 5850 and a 6950 running right now... but there is an empty PCI-E slot that I want to get put another 5850 into, but I might shell out some cash and get a 7950 just becase I want one. I think I will need to get a 1000W supply to run all three though... actually, I have a 630W laying around, so I could just run two PSUs.

haha! Well I won't be able to crack the top 5 until I can convince my wife to let me get another card. I keep telling her I have this empty PCI-E slot that is just begging to pick up an axe and mine. My other issue is that I doubt that my 850W PSU can run 3 cards... What an unlucky round...
yea, luckily it was preceded by like 2 days of rounds where over double the number of blocks expected were found. Yeah too bad I was still trying to mine BTC during that time period Oh well, I am here for the long haul. FTC seems like the best place for a GPU n00b miner like myself. Besides, I like seeing my name in the top 10 list of the pool haha i see a challenge - when im not mining LTC im usually 5th

Mine scrypt...
I highly doubt there will ever be an ASIC for scrypt, so GPUs are going to be the norm for scrypt mining.
The main question is will ASIC mining of BTC kill all cryptocurrencies? It could because it will force people who are still using GPUs to mine SHA256(BTC) to switch to Scrypt(LTC) if they want to make any coin. This will just make LTC/FTC/etc more difficult to come by.
I just started mining last month, but overall I have only put in $140 to my "rig". I bought a 5850 for $80 and a 850W PSU for $60, and slapped them into my PC with a 6950 I already had. I get about 800MHash/s for BTC (800KHash/s for scrypt).
I've only made like $30 so far, and will likely piss that away with gambling, but I did it more for fun and experimentation.
My advice: Don't buy new hardware if you can avoid it. Spend $60-80 on a 5850 instead of $300 on a 7950 unless you just have a lot of extra income OR you want to upgrade your graphics card anyways.
I plan on getting a 7950 or 7970 next month but that will be going in another desktop that I will only mine with while I sleep/work.
I'm a n00b though, so I could be wrong, but I think there is still profit to make here. A lot of people pay some ridiculous amounts for electricity, too. I'm in Texas and pay $0.06/kwh... so it costs about $40 to leave my computer on all month. On average, I make ~$2-3/day right now, so I get a small profit, but it's not really about the money for me as much as it is the experience.
It's a way better hobby than smoking rock and playing dice.

How would I go about giving my collateral? Say if I had stocks, how could I "lend" it to you for the length of the loan?
Talk to your bank. I have 500 shares of FNMA... I'll throw 3 of them up as collateral for a 0.05 BTC loan lol I don't understand collateral on such a tiny loan.
|
|

Can I get a 0.05 BTC loan? I want to bet it on the Rangers to win tonight...
If they lose, I mine at 800MHash so I can get it in a couple of days.

I think you can take chips and make them able to mine by paying a person.
Sorry i didnt get that. What you mean with "make them able to mine" ?? You'll have to find someone who knows what to do with the chips. I've thought about buying some, and hitting up a few people to help research it... also thought about doing it myself and documenting all of my follies on the intraweb. Apparently you need 8 chips minimum since the only configurations that seem to be out there are 8 and 16 chip boards.

I'm a complete n00b when it comes to PSU issues.
Backstory: I thought my 630W Antec was going to be good enough to run my 5850 and 6950 but it would shut off after about 15 seconds. So then I pulled out another 400W PSU that I had laying around, jimmied the starter pin with a paperclip so I could turn it on and ran that directly to the 5850 with the 6950 being powered by the 630W. Same issue. Decided I just wasn’t getting enough power, so I got an 850W Antec TruePower Quatro for $60 on Craigslist. Now everything runs great off of the single PSU.
Question: I am looking to get another video card (either another 5850 or a 7950) to fill my 3rd PCI-E slot. Will the 850W be enough for all 3 cards or will I need to upgrade the PSU again to run three cards?

Heard good reviews on this, so I decided to check it out. Only deposited 0.01BTC to start with, but was just curious how long it takes to show up? It's been 20 minutes and still showing a zero balance. Also, think you will start accepting LTC anytime soon? That's what I have been mining lately, but I can easily convert it over. Thanks in advance! EDIT: It deposited after about 30 minutes. Not sure if that is the norm or not, but pretty cool site and I will definitely be back!
