Cryptocoin Mining?

[markyh]

The 7970 in my sig is running at 89C @ 79F degree ambient mining litecoin at 525 kh/s

It starts throttling at 95C @ 85F degree ambient.

This is with fan speed at 100%

Mining litecoin my MSI R7950 boost edition is running @ 630k/hash @ 66 degrees and 54% fan (auto). The rig (ex 20w monitor) is drawing 280w.

Afterburner core voltage is set to 1038mv to acheive this.

Set up for BTC or TRC with downclock of memory spped and voltage to lowest Afterburner will allow, and GPU voltage set to 1019mv, it pulls 500m/hsh @ 57 degrees and draws 200w, so getting 2.5m/hsh / watt.

It can up the voltage and get it to pull 590m/hsh but it then draws 300w which is just under 2m/hsh / watt.

Too hot. Running 24/7 at temps like that will kill your card in under a year, probably 6 months.

My 7950s run around 78C (83 F ambient) at fan speed 60%, and I still think that is too hot. I ordered some 80mm fans today to hopefully get them below 75C today to allow some OC headroom.

I would have to void my warrantee to make it cooler.

I could care less how much I cost XFX in RMA costs when they sell me an inferior product on all accounts.

yeah the xfx started out all unlocked I spent a lot of time and effort fixing the two locked ones that I am stuck with. I have 2 unlocked and 2 locked.

Mine seems to be running around 70c most of the time at 80-90% fan (fan is on auto) so I assume thats ok as far as temps are concerned. I don't like the fan rattle but I'm not sure what I can do about that.

Price is down to 68 usd per coin =/

Brace yourselves for sub-$20 coins, perhaps even single-digits again. I tried to warn you guys. Meanwhile difficulty is going up, up, up, especially when Avalon's next two batches of ASICs hit.

Has to go back up at some point.

Denial, Anger, Bargaining, Depression and Acceptance.

Unless of course you were talking about difficulty, which yes, will continue to skyrocket.

You may be right. In fact, you probably are right.

But on the other hand, "Prediction is very hard, especially about the future".

 

[hokies83]

It may go down due to what ever reason... It has before..

But it has always came back up... look around the 100$ per coin range seems a likely place to end up.

He's been wrong every single time before, he is just saying the same thing until he happens to be right.

He's like an NPC in a video game .

But yeah, the point I'm guessing he's trying to make is. If you don't understand capitalism, don't invest money in anything.

EDIT: VVVVVVVVVVVV I wonder who the angry one is here VVVVVVVVVVVV

93 posts since 2007, I guess I must have angered you enough to post. Lol. Yeah, I'm wrong "every single time," keep telling yourself that. I never said such a thing about capitalism (wtf?). And I have also never said that BTC will go to zero forever--though The Economist and others have pointed out that Napster was one of the first but ultimately lost out to newer tech like bittorrent, and Bitcoin could be the same thing. Bitcoin could well be the Friendster of P2P currency that gets superseded. The whole "hash protects the network" argument is not dispositive.

Anyway, BTC follows boom-bust cycles just like everything else. I've traded equities and commodities for quite some time now and BTC is not immune to boom-bust cycles. Sure btc might come back, but there are other things you could do with your money in the meantime that would be more profitable.

I find you to be funny, in a good way. Personally, bitcoins aren't really for me, I prefer something I can analyze and hopefully predict a little better than BTC. I figure if they ever come back down to ~10$ I might pick up a few. I'd get them cheaper than mining for them on my comp and at that point, the potential upside versus downside is greatly in my favor. Everyone needs something to gamble on once in a while, right?

Bought a Sapphire 4L from newegg. So much better that the DD.
Put it in the slot above an xfx and undervolted, they both run about the same temp (with another xfx on top, it wouldn't run full speed it was so hot). Pretty sad.

I am thinking along the same lines, at least for LTC. I think this graph is the most interesting of all:

During the first rise and fall LTC looked completely decoupled of BTC and had its own life. Then around the 8th it looks like somebody manipulate the LTC to BTC to remain at 2.5, probably by some bot trying to make a profit from small variations. But it slips and stabilises at 2.0. Then a sudden jump up to 2.4 where it remains for a day before the new exchange rate is apparently set to 2.5 again. No way this is random ups and downs... Only the last day we see this scheme breaking, probably due to BTC holder fleeing to LTC. This tells me that the market is much to small if it can be controlled in this manner, and investing in such a market is asking for trouble unless you have insider information. BTC itself however is bigger and can probably not be as easily controlled.

As it is I am not really concerned about the price at the moment. I worry more about the difficulty since I rather mine a few coins at low difficulty and hang on to them for a year or so. If they are then worth nothing, so be it.

They already hit, who do you think unkonwn is on:

ASIC makers keep on missing ship dates, and then releasing units in waves. Manufacturing doesn't work that way, they are obviously setting their units to mine and then release a "wave" every now and then based on their feel of the market. they might be limiting themselves on how many ASICs they have running concurrently actually to not sour the market.

Price is crashing down again =/

Yes in USD, BTC is dropping and LTC is tied in it seems, however, the BTC/LTC price is much better than the crashes last week.

There we saw BTC/LTC drop to around 0.18 (maybe lower?) before leveling of to 0.20-0.22. Now we have broken above 0.25 and seem to be steady around 0.27-0.28.

For this reason after I get paid my next whole LTC from give-me-ltc pool in about 6 hours i'm going to conver the 9 LTC I will have into BTC while this rate holds.

Then i'll hold the BTC until hopefully the BTC/USD reaches $100+ again before I sell.

Looks like some porn sites are accepting bitcoin now..lol

They're probably using Bitpay, so they can get the cash instead of holding onto the Bitcoins.

Seriously guys... if you were running a business that needs consistent profits to pay your expenses and make payroll, would you want to be holding onto Bitcoins right now? During any given day, they can go up or down as much as 50%. Good luck trying to make a budget with that kind of volatility.

Hell... even the folks on the BTC-E "trollbox" think that Bitcoin is headed down to $30 before it rebounds, and they are the biggest cryptocurrency supporters.

 

[TheUnk]

Are there any gambling sites that accept bitcoin?

Heh... there are a lot of them! The biggest one is probably Satoshi Dice, but there are plenty of others.

It's failed to go below $50 twice now. Not saying it can't happen, but there are apparently a lot of buyers who have decided bitcoins are worth $50 and won't let them fall lower. Eventually the weak hands who are selling will run out of coin to sell and only the strong will hold bitcoin, and the price will rise again.

I also believe there is a small chance bitcoin will fail completely and go to zero, but that would require some serious problem, not just normal market fluctuations. Still I consider this a risk, but I'm willing to invest despite it. Any good poker player knows you have to play the odds, there is always a chance your hand could be beat, but if it's unlikely enough it's worth the risk.

In poker, your skillz can influence the outcome. In BTC, arbitrage bots and the like excluded, you are basically speculating, and if you have such good speculation skills you can make so much more buying/selling btc directly. Or hell, even outside of btc, in the fiat markets (forex, equities, bonds, commodities... I remember my very first commodity futures trade and how I nearly doubled my money in two days), especially since you can get leverage there whereas there isn't enough market depth in the one place I know of where you can do stuff like short and use leverage--and even then the counterparty risk is sky-high... we all know what happened to places like InstaWallet when the going got tough.

Also, this $50 support level and $50-100 trading range is possibly like the briefly stable $15-20 range after the 2011 peak (see chart: http://bitcoincharts.com/charts/mtgoxUSD#rg730zczsg2011-04-30zeg2011-10-31ztgSzm1g10zm2g25zvhttp://bitcoincharts.com/charts/mtgoxUSD#rg730zczsg2011-04-01zeg2011-12-31ztgSzm1g10zm2g25zv). I've been caught in more bull traps than I care to remember over the years, and this one just smells like one to me.
