Cryptocoin Mining?

[Suspicious-Teach8788]

my two 5830s are running 85 and 80 respectively in an open case.

in a totally open environment my 6850 is running 86 and my 5830 is running 71.

The higher temp represents the one that is suffocating because there's no gap between it and the 2nd card.

Also, what do you guys think will happen to Bitcoin rates if the US debt ceiling crisis goes haywire on Aug 2 and we get downgraded?

Is this possible to figure out how much of a M/h is equal to bit coin value ?

I would definitely do this during the day while I am at work, except I don't want to be involved in whatever brute force hacking this accomplishes. I just wonder what the outcome is, whether it is trying to decrypt messages, or just hack bank accounts. Whatever it is, it has to be worth quite a bit if people are willing to pay this much for it.

Come on, everyone knows the CPU power isn't used for brute force hacking. It's used to devise new superior methods for torturing puppies.

Not sure if serious...

your going to have to separate those cards,this isn't the best looking solution but it's very effective.this is some scrap wood and a 12 dollar extender cable(in fact i used bitcoins to pay for the cable)

does painting it black make it go faster? (graduate of tweakboy school of overclocking)

omg. just when i thought the luck was goign back to norm we seE:

Average shares per block: 1482201 (-14.1&#37
Average in last 24 hours: 1159148 (-45.9%)

 

[hdfxst]

maybe i should paint it blue or is it red

i hope it stays like this for a while,i'm back to .60 btc

How long do you guys think it would take to recoup $1500 at 2000 MH/s?

According to this calculator, it would be six months. But that does not account for increased difficulty.

Do you think I could do it in a year?

Probably, but it's a very huge risk to start right now.

It is a big risk, but also keep in mind you can probably resell your hardware when you quit mining, so 100% recoup of costs isn't require to break even. Given $1500 figure, I assume he is thinking of using 6990 or 5970s, which would put him ahead of the game when he resells, since the market will be flooded with used 5830s.

One thing I'm really liking about the AM3+ & Z68 chip sets are the space they leave for Crossfire & SLI. I'm running two HD 5830s in an AM3+ board with no heat problems. Both are OC'd near 1GHZ and stable giving me a bit more than 300 Mhash/s while hovering under 75F.

My 6970 on the other hand is running 90c while giving me a bit more than 400 Mhash/s with a very slight OC.

That is a good point that 6990s will be a lot easier to resell. Still I think it is almost double the cost of using 5830s. I might go with 6870s just because they seem to be the only card that is readily available.


If I go with the 5830s or 6870s, are there any the pros/cons of a 3 video vs 2 video board setup (two or three video cards to one motherboard). I'm would obviously be more efficient than building more two card computers, but I am a little worried about stability since I've never run a 3 card setup before.

 

[YoungGun21]

I don't think it is a good idea to put $1500 into this now. A month ago, maybe. 3 months ago, sure. Now, no.

 

[gorobei]

i've said it before, southern islands release will torpedo any resale value of 5 or 6 series cards as well as spike the difficulty for at least a month or two.

since the op isnt getting hemlock or antilles, the resale value will be minimal.

also, the stable $14 and mild difficulty bumps are making people think about upping their hashes again. there has been a bump in daily growth rate, expect a larger diff bump soon. even 2000 Mhashes wont be enough to sustain a 1coin/day return.

 

[Zargon]

there has been no confirmation on if they are vlw4 or 5 or wahtever right?

so how can you be so sure?

 

[Suspicious-Teach8788]

is there a reason for me to stick with deepbit? should i look into other pools?

 

[gorobei]

it isnt a case of vliw 4 vs vliw 5, or even vliw vs gcn(simd). assuming they are going gcn/simd then the transition at worst case will be relatively similar to nv's switch from gf200 to fermi/simd. at the the grossest analogy, older dx8/9 pipeline games can give a rough estimate of what performance was lost when nv went simd. per sp/core performance went down but the die shrink allowed them to cram more cores in so overall dx8/9 performance was up just not by that much compared to dx10/11 games where simd parallelism was getting 2-3 times more fps.

general article reviews of the gcn unveil indicate that it may be a vliw4 in a smaller sub unit inside a simd cluster with scheduler. so overall integer function shouldnt suffer as much as fermi which stressed double precision floating point. the die shrink alone should be enough to keep or improve performance over cayman. the only thing that could hurt the shrink gains is if they go 28nm hkmg lp as the double patterning redundancy traces could eat up a lot of real estate die-wise thus lowering number of cores.

regardless of what architecture they use on what process node, the number of new southern islands card owners and the general gaming performance increase will have a negative effect on 5830 mining. sheer numbers of new owners will increase # of miners, total compute power, and eventually difficulty which is the critical part. the 28 lp could make SI way more power efficient which would drive resale value of 5830 down. the overall gaming fps gains will make the 5830 less valuable resale-wise regardless of hash rate. who would buy a 5830 for gaming when cayman/barts price will drop and the new SI cards could be better miners and better gamers?

6 series becomes the new 5 series in BTC mining then.

 

[Chiropteran]

6 series is slower at mining than 5 series, generally.

I forget people game on those

11.8 Preview is out as well credit to @catalystmaker on twitter

 

[YoungGun21]

Yes, the 7000 series will kill any resale value of the 5 or 6 series, but it is yet to be seen how much of an impact it will have on mining. I expect to be trade-only by then, so I'm not too worried at this point.

Yea I would like to know that too
