Cryptocoin Mining?

I would not follow a email link, there is a claim site, but get there from from mtgox.com .
I read there was a look-a-like mirror site up for a while that was grabbing unsuspecting information. Not sure if it was true.

That's what i was worried about.i figure i would wait until mt.gox is up and running and then get my acct. fixed

even a farm of rack servers is less powerful than a multi gpu rig. a single i7 920/2500k/2600k barely get 10Mhash/s. a rack of 20 would still be beat by a 5770.

5 months ago, yeah it might have been worth mining with cpus, but ever since june it isn't worth bothering.
 
Did anyone else get an email from Mt.Gox on account recovery?this is part of the email: You can now enter the account recovery process on Mt.Gox to get access back to
your account by filling as much information as possible on this site:

https://claim.mtgox.com/

maybe i'm a little gun shy but is this legit?

[Update June 23 - 03:15 GMT] Clarification on the claim process.


Once you have gone through the first step of reclaiming your account at claim.mtgox.com an email will be sent to the email address registered with your account.

Within that email a link is provided that you will need to click. This will verify that you are the original owner of the Mt.Gox account that was reclaimed.
When we have received enough reclaim requests, a follow up email with further instructions on how to access your account will be sent out.
 
i don't even know where to begin with how stupid this is.

That a nation happens to have sovereign holdings of gold does NOT mean the economy nor the currency is backed by gold.
japan has something like a tenth of the US in gold reserves but their GDP is a third of the US.
Gold holdings has little significance to current economics.

currencies are NOT backed by any production, any business can refuse service to any customer regardless of money.

ohh forgive me, what i read in this thread qualify for the Nobel price in economics.

Just got my HD 5830 today. Now I'm going to have to move some things around so I can plug a monitor into the card. Since I didn't even think about the dummy plug issue. I also don't know why it surprised me how big the card is.

Hehe... My single 5870 fit in my mid tower, it was tight but it fit and functioned perfectly. I got a second 5870 without even thinking about the case, and, well, I now have a full tower so I can have Crossfire. 😉

The 58x0 are big cards.
 
Well, looks like the difficulty is increasing in about 6-7 hours here. A 56% increase to over 1.35 million. Yea, its has officially become too late to buy new hardware and make a profit.

A 5830 added tonight would generate 1.6 bitcoins over the next week. Then the difficulty would go up at least another 50%. Then it would generate 1.06 bitcoins for that next week. Another 50% bump. .707 bitcoins following week and .476 bitcoins the next. This is with a severely overclocked 5830 mind you and also some assumptions which are very probable and probably a little conservative.

We are looking at a total of 3.843 bitcoins in a month of running the shit out of a 5830. To recoup the costs bitcoins would need to be valued at 28.6 USD. They are currently valued around 12-15 USD.

Yes, actually. It's merely a matter of making it technically unfeasible for it to be counterfeited and to cause it to hold value or for there to be a market for it.

I think the bitcoin is doing remarkably well at both tasks considering it's the first attempt at something like this.
 
Yeah I'm trying to finish up one last Bitcoin before the jump, I should be able to make it. These things need to get back into the mid $20 range. I have a few coins so if that happens I'll be ok for a little while.

Mt Gox is also reallying annoying me. I'm glad I only have 2 Bitcoins in them but man is this frustrating.

How do you get the data on which dates and by how much will the difficulty increase?

The next increase is widely displayed everywhere, but the place I usually check it is the page with all of the different markets. As for the other difficulty increases after that, they are all speculation. He is assuming that a 50% increase will hold true, I don't think so. I think that the network growth will slow, so that maybe 3 or 4 increases from now, it won't go up more than say 25-30%. There are already miners that are dropping out at this difficulty, I would imagine some more will begin to drop out during the next 2-4 weeks.
 
With the difficulty rise my ~4 gh/s farm is down to ~2.5 btc per day. At current $15 BTC price that is around $37.50 a day minus ~$10 per day in electricity equals ~$27.50 profit per day. Still worth it but will definitely have to re-evaluate at the next difficulty increase. Not having a house with 5 computers running that sound like jet fans is worth something...

Jesus H Christ! Where are you located?
 
i was going to build a gaming rig so i tried dabbling with mining myself now.

6950 crossfired gives me about 600+ mhash, i've generated about ~1 BTC in the last ~1.5 days.

Totally not worth it imo, running this is pretty hard on the computer.
The GPUs are full load 80C+, PS full load with 12V slightly sagging.
Plus you have to listen to the fans running full blast 24/7.

The GPUs can handle it. Looks like that means your psu is crap? Thats why you do it when your not in the room.
 
My computer room is pretty much diagonal across the hall from my room. I just close the door to the computer room about halfway and the door to my room about halfway. This pretty much blocks the sound and still keeps air flowing.

First off, it is better not to crossfire.

Second, why are they running at 80c if your fan is running full blast? I'm guessing your "full blast" isn't actually 100% fan. Those should be under 65c with fan at like 80%.
 
How do you get the data on which dates and by how much will the difficulty increase?

I go to http://bitcoincharts.com/bitcoin/

It tells you how many blocks are left and the number of blocks per hour. Some simple math gets you about when the next difficulty is going to be. They also predict the next difficulty, but it only really becomes accurate when there are sub 100 blocks left to find. Also, for some reason, the last day of mining at a difficulty the blocks per hour nearly doubles, so it always comes earlier than you predict.

go into CC and clock them down, up the fan some, and turn the power down.

mine runs pretty cool like that, sure it only does 200 mhash but Im not having to worry about the card dying from effing with btc's


wait never mind stop mining, more for me before the diff jump 😀

50% is low, as is evidenced by our over 57% increase last night. The difficulty rise before that was over 55%. Its accelerating, not decelerating. In a month, no one will be mining any more. Only a few people will be left who spent tens of thousands if not more or who have botnets or who have some other scheme.
 
I plead the 5th on the power supply, haha.
I ordered an antec TPQ 12000, so that should be enough, but even with a much bigger one, it's still a heavy load 24/7.

I have messed with the catalyst settings, but it's really only the top GPU that runs hot, the second, lower one runs 10C cooler.

I'll probably still just mess around with it for a while, but like everyone already said, this isn't really a profitable endeavor to start from scratch now.

Given the TPQ 1200 is a 1200W PSU, I highly doubt that you'll even go over half of the wattage.

Here's the power usage portion of Anandtech's review of the Radeon HD 6990:

http://www.anandtech.com/show/4209/amds-radeon-hd-6990-the-new-single-card-king/18

I chose this one because I knew it would have the 69XX cards in Crossfire, and it certainly does have the 6950CF listed. As you can see, their setup only used 470 watts in Crysis, and 509 watts in Furmark (which should be maxing it out).

Essentially... 1200W is overkill 😛. Although, since the PSU is 80 PLUS SILVER certified, it should be plenty efficient at that low draw.
