Cryptocoin Mining?

[Pooptacular]

you think I can do two 7950's and a 7790 with a 650 watter? Should be fine I think. Is tri card mining recommended?

Two cards in a case hash at less than one card in the same case. There is more heat to deal with. Three cards would cut this down even more. My dual 7950's can easily break 600mh individually at 1150+mhz, but I run them at 950mhz-1080mhz (0.95v-1.012v) in the same (closed) case, giving me 1000-1100mh total, depending on the room temps. These are fixed voltages and speeds I set, not auto cgminer settings.

It's easy to install a group of cards in a case and try to get your heat/speed settings tweaked, just don't expect 3 cards to do 300% of the 1 card hash.

Thanks for the interesting facts.

There's always Mhash/J to consider. Adding extra cooling to a single case with two cards is probably more efficient than two separate systems, even if they won't clock quite as high.

Yes, it seems the time to buy cards just for mining is at an end. I've got 2.2ghash in my stable now and plan to mine with it for a while yet, but as tempting as it is to add more cards, I don't think it makes sense at this point.

I think I actually got this as a trojan, maybe some hacker trying to mine from my computer. I turned on my pc and I noticed both my 580 SLI is being utilized 100% on idle. I ran malwarebytes and that cleared it up. I was using Win 8 with its built-in defender, I was surprise it did not detect it.

Sorry, I'm a bitcoin noob, can you explain this a little further?

I'm trying to understand this because my brother and I just started playing games together again. Xbox 360 graphics don't cut it for me, especially past 55 inch screens, so I'd like to know what card I should get that'd pay me back, or recoup a large part of my investment. If I spent 1k on my system, and was able to recoup 300-500 dollars by the time the next iteration of AMD cards come out allowing me to upgrade for free, and sell off my old card, then sign me up haha. Anyone who can explain it in like 5 sentences (no one wants to sit here and write out a long explanation I understand), that'd be really helpful to me.

5? I will try.

1. You still make more money than you lose due to increased electricity costs
2. With typical single card mining rig you make like $2-3/day so if you run it 100% mining you could break even after a few months
3. But you will game on it too so make it maybe half a year, plus difficulty will rise, so you will make less money per day as time goes on
4. The above assumes that value of your coins does not change, which it will in an unpredicable fashion
5. You can recover some costs by selling the card when the new card is for sale, but at a lower price since many people will do the same trade

Will mining efficiency increase next iteration? The GTX 780 and Titan are jokes at it.

The difficulty is increasing 10% every two weeks and probably will continue to do so. This means that you make 10% less every two weeks than you did before.

By all means, if you want to buy a card for gaming and do some mining while it's still profitable, go for it. You'll probably recoup at least $100 over the next couple months.

My point was that buying a card just for mining doesn't make sense anymore because you'll probably never earn back all of your initial investment.

It will likely increase for AMD cards to be worthwhile. For nV cards, even if they increase Titan's a decent amount, it would probably still not be worthwhile. nV's current architecture just does not suit mining.

 

[Chiropteran]

A bit of a rally on bitcoin value today, up to $133 after sitting close to $120 for the past couple weeks.

 

[Smartazz]

Anyone else have opinions on using Campbx to deposit into my bank account? Going to cash out some of them.

Actually, it's worse than the above. If price stays constant, and difficulty goes up 10%, your REVENUES go down 10%, but your PROFITS go down by more. This assumes you pay more than zero for electricity and depreciation (video cards lose value over time) and whatever else in operating costs (e.g., higher air conditioning bill, etc.).

Example:

Say you make $10 per week mining, but your operating costs are $6 per week. Your revenue is $10 but your profits are only $4.

If next week your revenues drop 10% from $10 to $9, and your costs are still at $6, then your profits are only $3. You went from making $4/week to making $3/week, a 25% drop.

So a 10% drop in revenue led to a 25% drop in profits in this example. This is always true whenever your costs of electricity and depreciation are greater than zero. Obviously these are not actual numbers but the point remains: a drop in revenue results in a FASTER drop in profits, whenever your operating costs are more than zero.

Only a fool links to a bank account imho. Use dwolla or something else.

 

[BallaTheFeared]

Is Dwolla still working after the feds hit them?

 

[Smartazz]

I'm wondering this too.

 

[chimaxi83]

Transferring money from Mtgox is just one thing Dwolla did, and it's still up and running fine.

 

[Binky]

My understanding is that the feds took the mtgox dwolla account. I don't think dwolla was affected, except for that dwolla account (which wasn't even dwolla's money - it was mtgox).

 

[BallaTheFeared]

You me to, from Dwolla, to Gox?

Can you send money from Gox to Dwolla, to clarify?

 

[crashtech]

I gave up and Mtgox and Dwolla, and just use Coinbase now.

 

[jimhsu]

Given recent events, I probably trust Dwolla less than coinbase/campbx at this point. Plus they said about "security check" and flat out refused to approve me for an account with replies to them unanswered (when everyone else apparently had no problem). So no, won't be using them.

 

[Elfear]

That's who I'm using too. Transactions are very easy once your bank account is verified. Fees are a little higher than MtGox/Dwolla but transactions are faster and more convenient.

"If price stays constant" is a pretty DAMN BIG IF.

i'm mining with a single 7950 right now... and i honestly feel like it's almost time to give up on mining. difficulty has been going up pretty fast lately... obviously some people finally got their ASIC's

well they still make a little but maybe coins will trend up closer to 175 or 190. I still think the best advertisment for amd is buy bitcoins and drive up the price. Thus getting more people to buy the cards like the hd7790.

If I went to MtGox with a 10 million dollars to spend bitcoins would jump up in price.

Todays volume was 49000. So round to 50000.

buy coins in bulk the price goes up.

50000 shares at 200 dollars is 10 million bucks.

just buy shares fast the price will go up and people will buy cards.

Buying coins would be legal for AMD buying coins in bulk would drive the price up.

A lot of card buyers are like myself ; miners. I can hope for AMD to do this.

One needs to understand most of the increased hash power is overpriced asics coming to market from asic miner. Avalon still ships slowly and BFL makes snails look quick.

Asic miner sells hash power at 2x the cost of a hd7790 card. (if you have an empty slot) So cards still get sold.. I now have 9 hd7790's and they have done well. I do feel that coins will spike in price again. If not I did okay since last August. But A nice price spike to 200 would be a good boost for me.
