Re: low price because of repeated large sells

I also think it's good in the long term that the price is going down. The late arrivals were complaining that the price was bubbled, too high, and unaffordable to the mainstream...

Well, here you go, maybe it will drop to the more affordable early-adopter levels again - USD parity or whatever...  Cheesy

B worked just as well at 33 US cents, for everyone except short-term speculators... Wink



Yeah, it would work great for everyone but the miners who bought their equipment for, let's say $1k, knowing that it would generate a maximum of, say 60-100 bitcoins over its lifetime due to increasing difficulty.  Not cool if BTC drops to 33 cents. Smiley  Ie. in order for the miners to stick around, there has to be some sort of reasonable ratio of difficulty to price.  At the very least to cover electricity (I get it cheap but it's quite possible that I'll spend half of my earnings on the utility bill this month at the current market prices and a difficulty increase).

I would take that as a compliment, he's the COO of Nintendo of America. It is quite a face and goes well with 'GOXED'.

Yeah, I'm not surprised that you'd take that as a compliment because I'm surely not the first person to say Jesus Christ, do we really all have to stare at the face x6 every time you open your mouth?  And I understand that there are all types of people, and one of them is the type that loves to annoy other people.  :|

Well, good points.  I'm more in it for the short-term gain right now, simply because I bought my miners with money that should have gone towards bills and food.  Smiley  But also, I think this is a valid point of view because if the miners don't make a profit, there's not much incentive to mine, and thus the hash rate and security will drop.  But yeah, let's get it over with.

Sorry to say this Jine, but as you may notice many people are leaving, and thats because many of the promised things, as little as they can be, are not being done. Something basic like auto-payout cant be missing out at this time.

No.  Way more likely they're leaving because they can't get work/connections.  I like the payout system the way it is.  I only left because my miners were idle.

And Chick, wtf is wrong with your signature?  Is that your face?  Why would anyone want to see your face x6 every time you say something?  Don't say anything cause I don't want to see it again, but seriously, that's the ugliest, most annoying sig on the site.

low price because of repeated large sells

Pardon me if this is obvious but...  I feel like one of the main reasons that the price of bitcoins is hovering around 14, rather than at IDK, 30, 100 Smiley, is that there are massive sells every so often.  I'm not entirely sure that it's just one seller at a time, but it sure looks that way when I look at the charts.  The price will be fairly stable, and then there's like $100K sold in one minute, and the price will drop 50 cents or a dollar.  It will slowly recover, surely greatly helped by massive buys at some point.  But I feel like it can't get too high because these massive sells always sweep out all of the buy orders. 

So it seems to me that there are a few players, whether they're early adopters or big speculators, who are keeping the market a lot lower than it would be otherwise.  Mostly because they can't be bothered to sell small amounts at a time.  And if any of them read this, please spread out your sells a bit.  Smiley

I like this pool a lot and wish it would work better.  I don't even care so much about the lack of fees.  I just like the site, the design, the philosophy, and the fact that it's in Sweden.  Smiley  So I hope these issues get sorted out.  +1 on the previous comments.

Re: recovering waste heat using a hexane steam engine?

Oh well.  Yeah, I didn't realize it was such a poor efficiency.  For reference, this is what you're talking about, I think:  http://en.wikipedia.org/wiki/Carnot%27s_theorem_%28thermodynamics%29.

Well, it seems like that's enough energy to power a liquid cooling system, so that you could have a self-contained cooler requiring no extra juice, powered solely off of the waste heat.  It'd be cool.  Not terribly useful but pretty badass.

Oh yeah.  I can't wait till winter.  I use so little heat in the winter, that I think what I'm generating right now by mining will be plenty.

Re: [2220 GH/s] Slush's Bitcoin Mining Pool (mining.bitcoin.cz)
by

on 12/07/2011, 05:42:19 UTC
I'm not doubting anyone's experiences, but for all the talk of stales, I rarely see any with slush. Also, my miners don't spontaneously crash (you should fix that), so the score based system is fair to me. I also don't get my panties in a wad whenever there's a hiccup or some variation messes with my expected reward.

slush has been responsive to every issue, actively fights ddos, and is active in this thread. That's about all I ask for.

Haha, yeah, I know.  You probably spent more money than I did and got higher quality equipment.  Smiley 

Still though, my stuff goes down.  Sometimes the power goes out momentarily.  Sometimes one card freezes up on my shitty dual card motherboard.  So then all of that work that I did before the crash goes to you guys, who don't have downtime, on the assumption that, because I'm disconnecting, I must be scamming. 

Sorry if I came off like a jerk, I'm sick and recently quit smoking and getting mad at everything. Smiley  Not trying to say slush is doing a bad job, I just think he and the other score-based pool operators need to change the scoring system, IMO.

I also feel like I made substantially less for a period of a few days than I should have, even when I was up and running full-time.  Not sure though at the moment, but that was fueling my irritation.

But also though, slush, IMO, your update on pointing miners to the new URL looked so much like the old update on that that I just plain didn't see it until I happened to read this thread.  Make it blue or green next time. Smiley

Yeah, I was thinking stirling too.  There's also some pretty swanky new steam engines out there.  It *would* look freaking amazing.  Smiley  There's just so much juice going into my cards, and so much heat going out, it's such a shame to not boil something with it. Smiley

Because of the score-based system, I keep losing a lot of my earnings when a miner crashes for whatever reason.  It's pretty frustrating to have 100-200 shares and have a score of 80.  I guess, now that I read this, it's because of a DDOS (nothing on the site that said this, just a barely noticeable item saying point it to api2, which btw, since you had that old one saying point to api, I didn't even see it for the longest time.) 
So I appreciate all the earnings, but I also don't like getting punished b/c of the score system, when my disconnects are not because I'm trying to scam the pool.  They're just routine crashes.  Smiley 
Couldn't you change the score system--why should I have a score of 80 with 100 shares, and have my other miners have scores of 10ks or whatever they are, and have like 150 shares?  Ie. be much kinder for disconnected miners.

recovering waste heat using a hexane steam engine?
by
speckman
on 10/07/2011, 06:19:46 UTC
I'm hoping someone can do the math on this: 

What if you liquid cooled your GPUs with hexane or water that heats up the hexane?  Make hexane steam (it has a boiling point of about 60C, depending on the type) to power a steam engine.  How much psi do you think you could get for an average high-end ATI card's waste heat?  I'm wondering how much electricity you could generate off of that heat.  I figure 1kw off of 150psi, just from looking around at kits and diy projects, which is roughly how much I'm using with my 4 gpus.  I'm rounding off a lot of numbers here though.

Re: bitcoin network the top supercomputer in the world?
by
speckman
on 24/06/2011, 19:00:05 UTC
Yeah, it is disappointing that nothing else is happening, like proteins being folded, cancer cured. Smiley 

I'm thinking though that more namecoin like projects will arise.  (I'm not too hip so I don't know about them yet.)  I'd like to see some way of doing the folding/seti@home type stuff with the bitcoin network (or rather people moving to it from bitcoin), a way in which people get paid for their work, but I'm not sure why that currency would have value.  Saw mention of a possibility of piggybacking onto the bitcoin blockchain for security? for other *coins. 

Like imagine there's an AI network, crunching away at finding better AI (sounds fishy but I'm just trying to summarize instead of spending 4 pages explaining Smiley).  Maybe if the miners are getting paid in shares, like stock, that can be traded for btc.  Like this AI company is going to use the power of the network to make really well-evolved stuff, and so is going to pay them to do it (in future dividends per share?), and the better it is, the better the company will be in the marketplace.  Possibly some small percentage of the power of that network would go to finding hashes for their currency or distributing the payments a la bitcoin, but it would be a very small difficulty, and hopefully could somehow piggyback on something else just for the security.

But the point here is that the bitcoin network is amazingly powerful, and it could very well funnel a lot of that power into related projects, just because everyone's sort of actively involved--more likely to see it and go there, being on bitcoin, than if they were just sitting in their quiet house, watching hulu, oblivious.  Which is where I was a month ago, with no hashing power.  Smiley  Now I have a gig.  And I approximately multiplied my total instructions per second in this house by 1000.  And possibly the decibels.

Re: Please explain the love for the 5830s and 5850s
by
speckman
on 24/06/2011, 18:40:19 UTC
I've seen a couple of reports in this thread of 4850's getting 80-90 mhash/s.  I've been mining on two for the past week and a half, trying to tweak them, but only reliably getting 55-60 out of them.  One is on a laptop, so that's to be expected... its gpu is clocked at 500 mhz by default.  The desktop's running at slightly over stock,  too, but I need to get the card cooler before trying any overclocking.  It's currrently running at 103 degrees C.  It's an old setup, so the fans could probably use some cleaning.  I've read that people recommend underclocking the memory, is that to reduce temps?
...
Edit: I think it's a cooling problem.  I stopped mining, let the GPU cool, then restarted it.  I was running at 67 MH/s until it hit about 100 degrees, then it dropped down.

Wow, I think the cards are rated to somewhere like 90C.  100C is really hot.  I personally don't like my cards at 80C.  I'm new to this but I never use the stock fan control.  I either set it manually in windows with the catalyst control panel or use AMDOverdriveCtrl in linux.  Especially in a laptop, I think you're going to burn something up, like your cards.   And yes, underclock memory to reduce temps.   Too low will also reduce hashes so experiment or use other people's values.  If I don't turn the fan speed up, my cards will rocket to high temps very fast.  Yeah, I'm stressing out the fans more but I've also read on here that higher temps shorten the life of your chips (just as higher fan speeds shorten the fan life)

I'm a little concerned about leaving my pc on hashing away 24/7 ! has anyone run into any problems ?!

cheers onis

Turn your PC off, remove your CPU cooler, and turn your PC back on. Watch what happens.

Fail safe in action.

Don't worry about fires, it won't happen. Your PC will shut down WAY before that happens, whether you are CPU or GPU mining.

I've fried CPUs, and GPUs by having a poorly secured cooler or a broken fan on the cooler.  I've heard there is a failsafe on ATI cards, but I wouldn't personally try it.  But you'd definitely get a fried card before you got a fire, unless your power supply was faulty, which can happen but it's rare.

Re: GUIMiner No OpenCL devices Found

Solution!  Service Pack 3.

Hey, I came across this problem again and was helped out on another thread.  Having service pack 3 solved the No OpenCL Devices Found problem.  I also needed .NET 2.0 (for catalyst) and python 3.2 for guiminer (solved the Application couldn't start, incorrect application information problem with guiminer).  (And I've done this from a scratch a few times so I'm fairly sure those are the minimum requirements on top of the catalyst drivers)

Service Pack 3 worked!!  For the record, the latest python is also necessary.  Thanks!

Linuxcoin:  I use it on another rig but this one won't boot a usb stick.  Just donated today--I love it.  Smiley

Well, it worked for 10 minutes, then I got a popup ATI error report (saying the card was no longer responding), requesting to send it.  Hashes showed like it was going but no activity in the control panel and low temps.  So I restarted guiminer, it went for 2 seconds, then the computer powered off.  Sad  And not in a gentle way.  I am letting it sit for a bit.

eramus:  Sure all of the miners are doing independent tasks, but the whole process is a brute force search for some really unlikely things.  So they all have to work independently, sort of, it's the nature of the task.  It's still a giant task.

Help with 6870 in Windows XP 32
by
speckman
on 24/06/2011, 03:50:15 UTC
First off, I'm sorry and almost sure this has been answered before, but I've looked for a while and tried a bunch of things, and I give up.

I have a 6870 that I'm trying to get mining on Windows XP 32 bit.  Got the catalyst drivers and stream sdk installed.  Tried 11.6 and 11.5  GPU-Z says that I don't have opencl installed.  Guiminer says the same thing.   I am using the card for the display, and the catalyst control panel launches (ie. the card is working).

I had the same problem trying to get a 5830 to work on a different xp 32 machine, but I got it to work on windows 7 64 super easily.  (windows 7 not an option on this--just a via nano with 1 gig)

For this computer, it's either xp 32 or linux.  I might go back to linux, but I followed one of the really popular guides to mining on ubuntu on here, and a couple hours later, after a reboot, my linux got hosed.  Smiley  And the stupid default ubuntu installer hosed my windows xp boot-capability.  So I started all over and figured windows should be easy.  Wink

Thanks for any help!
