anyone else have a solo miner outside their pools...? I have two GPUs mining in pools and another solo mining (4870, blech, ~90MH/s, but it's all I have right now to do this), I know it's a extremely low probability, but I'm hoping to basically "hit the lottery" with it since the block generation is totally random, IF it ever does find a block it'll basically deposit more bitcoins into my wallet than all my GPUs could hope to mine in their lifetimes anyway (50), so I figure it's worth the "wasted" 100MH/s...

thoughts...?

Yup, that's how it works. I actually started solo mining before I realized there were pools and managed to get one in about a week, when the calculated average for my setup was about 37 days.

With a pool you're essentially getting whatever percentage of effort you contribute out of however many blocks the pool gets. Solo you'll get the entire reward, but you have to spend the time doing all the work yourself. Over a long enough timeframe, they should work out to exactly the same amount. With a pool you're getting 1% every day, whereas solo you're getting 100% every 100 days. However, the difficulty could increase before you ever get one, meaning your timeframe just keeps getting longer and longer and you never actually get to the end of it.
 
if you want to solo then do it for namecoins. you are much likelier to get a hit. Right now they are worth 1/50th of a bitcoin but I suspect that will change once their difficulty gets closer to bitcoins.

true, but I'm gambling on the randomness paying off somehow, at ~500MH/s with all 3 GPUs pool mining I would mine 20 BTC in their lifetime, at 425MH/s it drops to 17.5 or so, I'm willing to risk the 2.5BTC on getting more than twice the BTC they would ever mine combined, hopefully my 6850 comes Wednesday and I can get close to 600MH/s (5850 and 6850 pooled) with another 90MH/s (or maybe 180MH/s if I continue to crossfire my 4870 and 4890) solo, I check to see what's up then after I recalculate I guess...

my very own bitcoin lottery so to speak...

I'm not going for likelihood and the payout isn't big enough to take that risk imo, I'm taking a shot in the dark to basically hit the BTC lottery...

I tried mining for namecoin. Without a better way of receiving it other than trying to setup a dos based server address or using a temporary address, it can become quite fruitless if you lose all that hardwork due to not having a wallet like bitcoin.

It's not using any more electricity now than it was for F@H/distributed.net. I know that in a purely mathematical sense it may be worthless, but I was already spending the power on it anyway. At least now I'm getting a little return from it. I'm half in this for the money, and half just for the hell of it.

And it will be a moot point if the HD5830 I ordered actually ships.

Does anybody else feel a little guilty though knowing F@H's goal was to find treatments for cancer, Alzheimer's, etc. while Bitcoin is pretty much just about trying to make some money hoping their value continues to go up with the difficulty increases?

Not at all. You think that pharmaceutical companies that come up with the cure for cancer are doing it for purely altruistic purposes?

I wouldn't mine folding for a higher goal, I did SETI/F@H for a few years back in the day, but energy costs are outrageous nowadays.

Click to expand...

How are you coming up with this number? At ~400MH/s I'm getting about .5 BTC/day. I'm not sure how much the increasing difficulty will come into play, but that sure seems like more than 20 BTC "lifetime" to me.

I totally understand where you're coming from though. It's sort of like buying a $1 lottery ticket every week - you don't really expect to win, and that $1 really isn't doing that much for you anyway, but it would be sweet if you did hit the jackpot. I just got lucky in that I accidentally hit the jackpot right away.

You might be better off doing the opposite, actually. Mine solo with your big cards that can keep up with the difficulty, and pool the weak cards that aren't likely to ever get anything on their own. If they can't keep up with the difficulty, at least they can earn you fractional BTC from the pool. *shrug*

this gets really old, really quick...

1. not everyone can afford to fold, you can, good for you for putting your computer to use towards a noble purpose...
2. how come nobody asks gamers the same thing...? a lot of gaming computers could do exactly what bitcoin mining computers do, some even better, why not try to guilt trip them as well...?
3. the attitudes of folders that keep coming into these bitcoin threads have really put me off on the idea of folding once I become more financially stable, I used to be interested in it and wanted to, but now that I see how the community acts I really have my doubts now that I ever will...

I really just don't get it, the holier than thou attitude from people who have no idea what our situations are like gets sickening, it really does, what do you get from asking such as narrow minded question...? a sense of superiority...? really...?

well then, I guess good for you...? congratulations...?

um. he asked a question. he made no accusations. why are you so defensive? why do you think he's a folder?

I plan on folding on the CPU in the winter (heat is heat when it's cold) while mining with the cards but while it's hot, the gpu's are paying for the cpu upgrades. So in my mind, I'm mining to help fold later.

ive only seen one or two such complaints, but you singled out Ualdayan and folders in general unfairly.

It doesn't matter. I just think your response was overboard.

one or two...? if you want to be taken seriously you'll have to do a little more research, I could easily quote more than that from one thread alone...

I actually felt a little guilty running distributed.net over F@H, since it was basically just theoretical math as opposed to working on real science that could actually help people. However, in the end, it's my money funding all this, so I get to make the final call on what I do with it, whether that's curing cancer or just looping porn all day. Donating some spare cycles to F@H was a nice thing for me to do, but I'm not a bad person because I'm not donating all my cycles forever to them. Like Omegas said, BTC profits could actually be used help F@H and other causes too.
 
So help me understand this whole PCI-E x16 on motherboards. I'm trying to find one that has 2 slots so I can use 2 cards... obviously. But most say one is x16 and the other is like x4. How does this affect the Mh/s?

And does anyone know which relatively cheap mobo, maybe ~$80 would do the job?

Thanks.

not sure what you mean, binaries are mostly the same as the original bitcoin ones. wallet is the same. only difference is there is no gui. the list commands are done by using the same namecoind program + command.

won't make a difference. important for games which need to transfer large textures through the bus. not for mining, which do not use heaps of memory. in fact it is recommended to downclock your memory so as to save power...

6870's are great miners as well. i get about 310mh/s overclocked to 1000 on the core.They also slip on the power.

Which had me thinking about the upcoming Radeon 6870x2 from PowerColor. Price may be an issue @$450 though but we know there at least will be a fresh supply of them.

There is also the 6970x2 but again, price and power consumption might be its Achilles hill.

Then there's also the 6950x2. If these could be unlocked they'd make for a pretty nice performance/value option:

I was laughing that in the future, when AMD released new graphics hardware, the thing people would really want to see is MHash/s benches.

could some one who's already tweaked their 5830 post their voltage, clock, and guiminer settings pls?
 
Price of NMC to BTC is pretty rocking right now. Currently 37 NMC will get you 1 BTC :D

Is there any gui for namecoins? I am trying the mining right now. I see how coins can be transferred but not sure how to tell what I have if/when I get a block

as for how, download the namecoind client,

http://dot-bit.org/files/namecoin_w32.zip

C:\Users\xxx\AppData\Roaming\Namecoin\bitcoin.conf
rpcuser=xxx
rpcpassword=xxx
rpcport=9332

start the client

then poclbm.exe -d0 --port=9332 --user=xxx --pass=xxx -v -w128 (or whatever)

a list of commands with namecoind help
can be run in a separate section for queries
Click to expand...

I just tried setting this up. Seems to be working but it's waiting for the blocks to download. Without a gui client how can I see how many blocks its downloaded so far?
 
What's the slowest cpu that would be able to handle dual gpu or quad gpu (6990x2) mining? I have a s939 4400+ at 2.2Ghz (stock clocks) with two PCI-e slots in the mobo. If I throw dual 6990s, would I see a detriment in Mhash compared to a more modern system?

I guess what I'm asking is if a 4400+ enough to run a mining server?
