Cryptocoin Mining?

[Spike]

i'm hoping there are still some 5830's in the newegg pipeline left to be released. i have an ip35e board sitting idle and the pcie 16 and 1 slots are perfect for a 2 card setup. that way i can give my main rig a rest from the heat.

i wouldnt think it would be worth it to run a pair of 1 card rigs electricity-wise. 2 cpu, 2 psu, 2 cards, 2 sets of ram. probably better to run 2 cards in 1 machine.

Your probably right, it would use less power though on basically idle ram, cpu, and the rest don't take much power.

Anyone know how well the 4870 does at this? I have one of those sitting around as well in another rig. Hey, I could have 4 different rigs running this at once all underclocked. Would that earn me some award for the least efficient bitcoin mining operation?

Well my 4890 pulled about 100mh/s

ouch, even a 90$ 5770 does ~220 mhash

Well, guess the 4870 will be remaining idle, not worth it. That 5770 in my brother in laws pc that he leaves at my place however.... hmmmm.....

BTW, what does the 5830 do? I keep seeing that mentioned as some sort of holy grail for price/performance but I have not seen any numbers. My 5870 and 6970 each seem to do around 340-360 at stock clocks so I'm curious where the 5830 fits in.

I'm running my 5830 at 925/400@ stock volts and getting 270 Mhash/s with -v -w128 -f1.the card has more in it but it's crossfired with a 5850 and the 5850 is getting to hot.the cooler on the 5830 xtreme is much better than the 5850 xtreme

How does one know when the difficulty will be going up? Is there a set schedule or does it depend on how many miners there are in total?

How does one know when the difficulty will be going up? Is there a set schedule or does it depend on how many miners there are in total?

It depends on the amount of computing power available to the entire network. So, if hundreds more people join with their AMD GPUs, then the difficulty will increase by a certain proportion. If people stop mining, then the difficulty will come down.

Basically, no one can manipulate how fast the Bitcoins are created.

 

[wbynum]

The difficulty increases can be predicted based on current mining rates. The next difficulty increase will happen tomorrow (Fri, Jun 24). It will be around a 50% increase. If someone hasn't already jumped into bitcoins it is starting to get to the point that it is questionable whether or not it is worth it if one has to buy the hardware. Also, certainly not worth it to mine on 4000 series cards.

It's late and i'm tired but am i reading that right.tomorrow will be a 39% increase and July 14 will be a 98% increase?I guess next month will have a lot of cheap 5000 series cards

My OC'ed 5830 does 310 Mhash on stock volts. Can get it up to 330 Mhash by increasing volts but not worth the extra heat. Incredible bang for buck...

Around 230 non-OC.

 

[tommo123]

curious - is there anywhere to sell these things? bitcoins i mean

 

[dajeepster]

i guess we've reached the outsourcing stage:

i guess you could run his client at a lower aggression and split the hashes.

I've seen that in the washington DC area also... same exact ad

Anyone else having problems with slush's today?
Woke up today to find out i've been mining ~0.007 avg per block with 960Mhash/s.

im getting about 300 on my downclocked 5870(keeping heat down)

Yes there are exchanges. MtGox is the main one but it won't be back up from its troubles until tomorrow.

Difficulty is only accurate projected one increase at a time. There is no way to tell what the difficulty will be on July 14.

 

[Smartazz]

How hard does this usually push people's GPUs? Do they operate near their TDPs?

 

[Absolution75]

The difficulty is skyrocketing. I doubt mining will be profitable soon without the exchange rate to match it.

 

[hdfxst]

right now 1 card is at 99% and the other is at 96%,but it depends on the flags f1 runs the cards hard but f120 runs at about 85-90%

Mine your machines: ABC probes security breach

‎I don't think its a good idea to attempt this....

AN ABC IT worker is under investigation for reportedly dragging the public broadcaster into a virtual currency money-making racket.
ABC spokesman Sandy Culkoff confirmed a serious misconduct case was under way after an insider yesterday tipped off the Crikey website that a worker at ABC Innovation sought to use ABC's vast audience and internal systems to mine for Bitcoins.

Bad idea there.

Ha - I just finished reading the entire thread. It was actually quite entertaining with all the BTC price fluctuations, hardware grabs, and the debate about the intrinsic worth of bitcoins. I do feel like I have a reasonable handle on the concept now. I've thought of a few technical/philosophical questions that were not answered in the reading that maybe someone could comment on:

1) What's stopping someone from starting a new bitcoin network with slightly different keys to create a second pool of bitcoins?

2) On the concept of de-regulation/non-manipulation of the bitcoin. I don't see the benefit. Organizations like the FED and the SEC were specifically created to regulate the financial markets to avoid economic collapses like the great depression (and are struggling to prevent a similar collapse today). This is precisely why most countries got away from the gold standard - to provide tools to prevent wild swings. Without regulation or manipulation of bitcoin, it is clearly subject to crazy swings (as observed) and ultimately severe market crashes. Why would such a currency ever be widely accepted?

3) Isn't this just a game among the miners? They're creating the bitcoins. I wouldn't be surprised if they weren't the one speculating on them too. You can gamble on anything - why bitcoins?

1. Parallel networks using Bitcoin's source code have been up and running for a while. But these networks simple don't have the support that Bitcoin has, i.e., exchanges, large community support, etc.

2. No opinion.

3. As a miner, I can safely say that yes, I am speculating on Bitcoins. But I have nothing other than a higher electric bill to fear, unlike the gold miners of the 1840s, who walked away from jobs and risked limbs to pan gold out West.

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

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

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.
