Cryptocoin Mining?

[Mir96TA]

I' don't O.C. ........
I tweak the Extra Flags and stuff........
Also I am not a Full yime Minner either ...........

Impressive. I shoulda got more 5 series. Tho I am.changing jobs and lost my free power n ac for a spare rig

Tapatalking on my pos thunderbolt. Sorry for teh typos!

Yes, you'll need to OC them to hit 200+ MH/s. Unless you choose to run them ragged at maximum intensities but lower clocks, not my cup of tea though. I don't have the kind of cooling to handle that config either. So I just crank them up a bit in MHz at reasonably low voltages.

 

[Binky]

I'm actually asking if it's possible to run them quietly, so that would probably be underclocked, not overerclocked. I see that they can hit maybe 200 when they are pushed.

 

[Vesku]

I answered, if you are running it quietly expect no more than 180 MH/s depending on clocks and intensity setting. cgminer is a good mining program in terms of access to settings, https://bitcointalk.org/index.php?topic=28402.0

just setup first miner. trying to figure out watts per coin. my setup pulls 200 watts and is stable. for my 200 watts I get around 400 Mhs. I should earn .18 coins a day.
This is 4800 watts a day. I will round up to 5000 a day. That is about $1.10 a day or $ 33 a month. If I earn .18 coins a day that is 5.4 coins a month. About 65 bucks. So the machine would make 32 a month before fees.

What I am trying to find out is comparable numbers. Does anyone know the watts they pull to the Mhs they earn. Is 200 watts to 400 Mhs good? Is 150 k watts for 5.4 coins good.

Obviously on paper I turn a profit. I was trying to figure what a good watt to coin is. I use a msi r7950 card. Underclocked due to heat. I can get it to do 500Mhs for 220-225 watts but it runs hot. I do not mind getting 200 watts to 400Mhs. Does anyone have a number to comare this to my numbers? tia

 

[Smartazz]

Difficulty is insane now. I can't get reasonable earnings with my 6870 anymore.

 

[thujone]

i'm not a stickler for electricity costs because mine is fairly cheap where i live... but my 7950 does 575mh @ 1100 and 602mh @ 1150. my temps get really high at 1150 though... got some new fans coming that will make it feasible.

 

[Mir96TA]

I always wonder what cause diffculty level to go so high ?
Numer of Minner ? or Minner Speed ?

 

[Vesku]

Total hashrate for the bitcoin network determines each new difficulty. https://en.bitcoin.it/wiki/Difficulty

For GPU mining 2+ MH/s per watt is where you want to be. Obviously, the more power efficient the better. However when bitcoin price is relatively high it can make sense to go for max MH/s during those times.

.

Perhaps I should ask what are core elements in bitcoin network which dictate the diffculty level ?
Cause with sort of diffculty level ............. Might as welll don't even bother!

Where can I find a guide for the flags used to control guiminer?

 

[RussianSensation]

Where can I find a guide for the flags used to control guiminer?

Which AMD card do you have?

HD7900 series, -w 256 -f1 (where -f1 controls the amount of CPU usage/priority with the lower number being more and higher number like 15 / 20 / 30 being less)

HD6800/6900 series, -v -w 128 -f1 (f1 works the same as above)

Here on a wikipedia page, there is a chart that has various combinations of flags you can try. The ones I posted above is what I found worked best, with -f15 if you want to minimize CPU usage.

Bitcoin value seems to be falling dramatically since $15 in the last couple of days. That in itself shows us that difficulty is just one small aspects of what determines the price of bitcoin - largely supply and demand imo.

 

[SickBeast]

Oh noes! $9 bitcoins! If they drop to ~$4 it will no longer be profitable for me.

That probably goes for most people as well seeing as my 7850 is very efficient.

 

[RussianSensation]

Ya that sucks. I was going to cash out at $15 but missed it that morning. It has now fallen to $8.25 and falling more.

You can see on the bar graph that someone/group of people are unloading large volumes of coins.

EDIT....
$8, $7.80, $7.70, 7.60, falling...

This is despite the Network total Hash Rate of 20.989 Thash/s (among the highest we've seen). This is proof that the price of bitcoins is not directly related to difficulty rate to mine the coins.

I turned on GUIMiner to check it out, first time (not looking for big profits, a little late for that lol). Why in the hell does BF3, overclocked and overvolted (1250 at 1.225V) push my VRM's to about 55C, but mining pushes them at that speed to 105C?! Core is water cooled, BF3 full load around 35C, but mining is 45C. Fast though, at least I think, with ~725 Mhash.

Hey guys where can i find a simple guide for mining? I've only got a 5670 for now, so not looking to profit, but i'd like to get my feet wet to decide if mining is for me.

 

[Mir96TA]

Crash! ?

Russian has a great post in a hot deal 7950 thread (this thread too I believe), and the first post of this thread will point you in the right direction too.

 

[RussianSensation]

The Network rate is now 23GHash/sec, and the coin is only at $7.80ish. Probably will fall more tomorrow. In 3 days, BTC lost 50% of its value.

I'm not too worried. If it crashes further, I might just buy some coins to invest. I'm not going to stop mining, as the brief time I stopped during the previous crash was a horrible mistake.

Thanks Russian, you also chimaxi83.

this.

 

[blastingcap]

Not necessarily disagreeing, but in these kinds of speculative bubbles, past behavior doesn't necessarily mean anything about future behavior. For example, even if bitcoins go above the low 30s again, it may take so long to do so (decades or longer) that selling at $32 would have been quite fine to do so.

Some people are known True Believers so take whatever they say with a grain of salt... if bitcoin were to go to $.00000001 they would still be mining and buying.

You need to put heatsinks on the vrms. You will damage your card at those temps.
