Cryptocoin Mining?

[hokies83]

Seems a 7950 needs about 100mhz to catch a 7970 in Mhash/s

What happens when we put power use into it since a 7950 uses less? i think this would end up making them Very very close in total profits.

Speaking of BTC-E how are you supposed to get money into it?

I noticed that too. Even by the normally very low standards of IRC chat channels, the channel at BTC-E is pretty awful.

I transferred in LTC in and sold it there to fund my account. You could buy BTC elsewhere and sell it at BTC-E to fund. Alternatively they take money from some dubious sounding places like "Liq Pay" and "OKPay".

just about 3 days in on this card (hd7790).

start cost was 111
that was after:
1) a code on superbiiz website
2) a rebate
3) sale of the game code
4) a credit card rebate


3 days of power = 1 dollar so 112 .
This card is 1/20 of all my hash.
My 3 day earnings are 1.38 coins for all my hash. Update 1.428

So 1/20 of that = .069 coins at $131.18 a coin that is $9.05.

update .0714 at $138.67 = 9.90

So 112-9.05 = $102.95 net.

update 112 - 9.90 = 102.10 net for 3 days in.

I will come back to this as I posted at 10 AM east coast less then 3 days in as 3PM today is 3 days runtime. Still the card's price has dropped to about 103 with all the deals , rebates and coins earned. This is the card in question.

https://www.superbiiz.com/detail.php?name=AT-77901OC


My point is No more risk for this card as of today.. I am sure I could sell this card for 115 which if I sold it on a website like this one on the sales thread 115 would break me even. I am pretty sure someone would want this card at 115.

So lets say you like any kind of gaming card and have a rig setup as long as your rig had room for this card It would add 80 watts of power and it could mine while you use your other card to game.

Note to mods I am not trying to sell this. I am illustrating a point of the risk to mine with a gpu.

fourth day card earns about 2.22 usd after electricity total earnings for the card .

$12.12 in four days. this brings net price to under 100. about $99.88.
I will track card for a few more weeks.

I bought btc from another exchange and transferred into btce.

I might snag one. The new miner I brought up today is a sonata 2 and it can't handle a 7950 and a 6870....too much heat

I loved my Sonta...until video cards got huge. I just retired it yesterday after running without the side panel for more than a year. Hell, at the end (i.e. last few months), i even had a 120mm fan sitting next to the case blowing cool air right onto the 7950 and 6950 mining cards.

My new nanoxia DS1 system with a 7970 and 7950 in it is happily mining away with less noise and lower temps than the open case Sonata. My Sonata is now sitting in a corner...of course I just "had" to put something in it which turned out to be an old amd crap board and the old and nearly dead 6950.

Also, I finally upgraded to 13.1 drivers. I think I'm seeing a slight bump in mhash from the old and trusty 12.8 drivers I clung to for a long time. I had issues with the 12.10 drivers so I stuck with what worked. EDIT: Screw the new drivers, I just had a hard locked system after mining for 5 minutes. I'll stick with 12.6-12.8 drivers.

 

[Zargon]

I had to bend the drive cage to get the 6870 in. Drilled some rivets. Rose will challenger is 40 right now....very tempted

yeah this is a nice card.

oc to 1200 and it ;
hashes 300Mh
pulls 80 watts max
uses just one 6 pin wire

set fan at 60%
temp is 61c.


I may unload some msi 7950's and some more 7970's. Then put these in while I wait to get my bfl asics'.


I was adding up all my numbers. I am about 1000 usd ahead and I have 13gpus running. in quite a few pcs. I need to reduce my watts used for the summer.

On GUIMiner it says:

2013-04-07 04:29:05: Listener for "******": nl.btcguild.com:8332 07/04/2013 04:29:05, Verification failed, check hardware! (0:0:Cayman, d9502621)

What does this mean?


Thanks

AMD 6970 @ Default clocks

[chimaxi83]

Try reinstalling and/or downgrading your driver version. Just something to try after reading a quick google search of your issue.

Hey guys, I know that GPUs are not supposed to be working at full load for days on end, so I'm wondering if I downclocked my GPU from 870-690MHz and left it running, would it be better for my GPU?

 

[Silverforce11]

To all the BTC haters I am proud to announce that I have paid off my two 7970 and two 7950 cards that I bought at the beginning of Oct 2011. This was with the strategy of selling BTC pretty much as soon as I got them.

Now they are making me money outright on LTC/PPC and will help pay off the 4 new 7970's I added to my mini-fleet last night.

OMG man.. so tempting..

is there a recent calculator for income vs electricity prices??

Down-clocking will only help heat and power related issues (These do effect board life-span, but do not effect chip life-span).

Under-volting will lengthen the life of the card for sure.

Hi new LTC miner here on a MSI 7950. Need some advice from experienced UK based LTc/BTC miners.

How do you cash out of LTC or BTC in to £ GBP to a uk bank account easily with low fees?

I know via BTC-E I can convert LTC into BTC with makes it slightly easier. But I can't see on easy and cheap (one step low fees) way to cash out regularly (weekly / monthly) into £ GBP?

I found this good guide for selling BTC ;

https://en.bitcoin.it/wiki/Selling_bitcoins

However it seems all the exchanges with good rates and low fees only work with USD or EUR.

I guess in the UK you maybe have to pay £20+ fees or big exchange losses going via usd/eur to Paypal to GBP , then Paypal withdrwal fees.

Or maybe opening a UK based € Euro current account is they way to go? and take a hit on transfering from EUR/GBP within the UK?

I have noticed from the posts some here are certainly based in the uk so any advice on how you cash out would be grateful.

Thanks

M

I tried some litecoin mining, and being in Europe lowering power consumption is important. I reasoned as follows:

• Litecoin mining needs high memory clocks -> go as high in memory clock as possible
• Power consumption and heat (and thus fan noise) increase with Vcore -> Undervolt
• With a given Vcore set core frequency as high as possible while maintaining stability
• I want to be able to browse internet etc while mining -> Set intensity to a value that still allows this without getting too sluggish

What I arrived at is 1000/1600 MHz @0.95 V, and intensity 17 (might lower it, it is a bit annoying typing now...) This gives me about 560 khash/s, at a total system power consumption of 255 W from the wall, screen not included. My core temp is 59 C and VRMs are 70/71 C after a few hours.

With current prices I would be looking at a profit of 9 USD/day (if I could run 24/7, which I can't). Does this make sense to you? What would you modify? At 1650 MHz memory I am getting crashes, and 1050 Mhz @ 0.95 V is sort of OK, but I got a crash while surfing in parallel, though 1000 MHz looks rock solid.

Let's say just 1% of the world's population sees the value in bitcoin as an alternative currency. Let's say that they each want the ability to store the equivalent of $1000 USD. That means:

.01*7E9*1000 = the amount of value the currency needs to be able to store = $70 billion

Let's do a reality check. If we look at the world's reserve currency, the USD, what's the size of the monetary supply? I think we'd want to look at M2, which is at around $10 trillion. So, Bitcoin would be sitting at less than 1% of that. That doesn't sound too insane.

So, to hold $70 billion in value across 11 million coins, each coin must be $6,363 in value. Look to the future of bitcoin and its 21 million coin limit and we're down to $3,333.

That means that if you believe in a future where Bitcoin has any importance at all, it's gotta go up quite a bit yet.

I think your 1% is too optimistic. That corresponds to the entire population of one of the EU majors, Germany/France/UK. I have a hard time seeing that happening unless somethings changes, such as that banks/Wall Street start investing in it.

 

[Zargon]

Most of Europe has basically banned cash transactions of over 1000 euro.

Cyprus is stealing its peoples savings.


Bit coins are the only way to move $$ without the EU tracking it around.

Just my .02



Wall st was dabbling in btc last year or so. There was at least one investment firm that was playing in the market

 

[BrightCandle]

As the financial crysis has gotten worse bit coin has become more and more useful. A currency not controlled by the government is appealing to more and more people for short term needs. Whether or ever becomes a currency that becomes common place I don't know, but its certainly got uses today.

Here is a good site to compare profitability of various coins, electricity costs, etc. Note that it does not take into account projected difficulty increases over time. See other site for that.

http://dustcoin.com/mining

On a side note, mining alt-cryptocurrencies continues to be very profitable. I switched 4 of my 7970's over to NVC last night. After ~12 hours I made ~$24. Twice what I would have made with BTC during the same time.

Now LTC is back on the rise so I have switched 6 of my 8 GPU's back to that. Two of my GPU's remain mining PPC as those two GPU's don't seem to like scrypt based mining (probably the PC or something).

 

[thilanliyan]

@markyh, sorry wish I could help but I'm not from the UK.

 

[Batmeat]

Having an issue understanding what a "suggested difficulty level" is. I use slush's pool and its a setting I can change in my account management. Best I can see is that it doesn't relate to mining difficulty.

So according to that, if one even pays up to 0.25 USD per kWh, 600 MHA @ 200W would make ~$5 profit a day or ~153 a month!! You can pay off a 7950 in 2 months if you get a nice one that OC without high vcore.

@_@ i am so behind the trend, even at 0.3 USD per kWh its hugely profitable.. a few months ago it was simply a loss for this electricity prices.

Yeah. It's interesting situation. Typically when price rises so does the number of miners, which increases difficulty and keeps things in line. But lately I think most of the big professional miners are waiting for ASIC, and ASIC has been continually delayed, so price is rising without equal immediate difficulty increases. I wouldn't expect it to stay this profitable forever, but enjoy it while it lasts
