Cryptocoin Mining?

[UNhooked]

Middlecoin was great for me for a while but lately not so good.

I can't comment on how on your KH/s but as for reliable multipool try http://us.trademybit.com/home/

They are new and everyone has positive comments about them. The only thing you have to do is set your Crypsty address to sell immediately.

I can't be bothered with it. If my rewards for hours of effort are always nill, how can I continue [mining]? Too much dissapointment and irritation. I have my limits.

I think I might have an Office Space moment with these miners at any moment.

Middlecoin is having some problems, but the admin/owner/author said he is working on fixing it, probably in next few days. There is some problem with coin switching, which is causing all the disconnects. Also, the european pool is only on DOGE right now, in case someone is using it.

Do you have to do the selling yourself?

Multipool.us is the same kind of pool right?

Yes you have to sell yourself. So you point the deposit addy to your cryptsy addy wit autosell rules in place. Not convenient like Middlecoin but the pool does have lower fees than Middlecoin.

Question: If I am getting too many rejects is it because of my hardware or the pool?

Also is target temp of 90 for R9 290s too high?

No one said mining was easy. That's a misconception a lot of folks have. You do have to allocate a decent amount of time fine tuning. However once you get it down and see the $$$ accumulating it is kind of hilarious since you are making $$$ literally by switching on a button

Take a deep breath and try again.

Who has either 290's or 290x's in crossfire mining?

What khash's are you getting and at what core/memor/fan speed?

Since watts are a topic of discussion I decided to check my usage and a
4770k
6950 stock ~400 khash @ 17 intensity
7950 0.95v 800core/1575mem ~475 khash @ 17 intensity

Totaling around 875-900 khash

Idle: 100w
Mining with the above intensities: 450w

The 7950 is undervolted and on low clocks and I haven't tried going up much due to sandwiching the cards side by side (basically touching).

 

[UNhooked]

I have 3 R9 290s but not Xfired. I was told not to Xfire them. It pulls about 1000Watts from the wall.

Full spec
MSI Z77 Mpower
G1620 Celeron
WD Black 250GB HDD
built in wifi module
3 X R9 290's
Sapphire Pure power 1250Watt PSU (Enermax Galaxy clone) Not the best for efficiency but I got it cheap and it's built like a tank.

All stock settings. And I get about 800 KH/s per card. I have been told it's low but atm I can't be bothered by tweaking it further.

 

[nwo]

800 is not low for a multi 290 setup, especially if you have not messed around with the clock speeds or cg miner settings. A 290X barely gets more than 900.

 

[wand3r3r]

Yeah I didn't mean actually in crossfire, just in the same system.

Are they loud (subjective I know but a trio has to be interesting) do you put them in a spare room or somewhere? Do they heat up a room a lot?

 

[DooKey]

I run both of my 290s in my sig system mining. I have a custom fan profile and they hover around 90C. I've turned the clocks down to stock and I'm getting 820 KH/s.

Noise isn't too bad because I have my system in my office on the other side of the house. I leave the window open on cool days to help keep things in check. Yes, they will heat the room a bit, but that room has a 4p and a 2p system running BOINC so overall the room stays fairly warm when the window is closed.

I'm currently sitting on 44.5 LTC. My total farm of miners gets around 5.4 - 5.7 KH/s on average.

Farm:

2x 290
4x 280x
1x 7990

 

[IEC]

I get ~810 kH for XFX Reference 290 and ~865 kH ea for Sapphire 290 Tri-X @ 1000/1370.

Reference 290 unlocked to 290X doesn't seem to do that hot, getting around 840 kH. YMWV with each card.

hey guys I know how to disable btc-e chat but how do I keep the chat but disable the refresh?

Thanks

 

[Silverforce11]

Has it worked out well for you?

Yes it worked out fine, I have an average of 2.1 Mh/s currently and past few days, per day I am getting ~0.03 BTC. Rejects are higher than other pools, at around 3% so far for me. Other pools I get anywhere from 0.5 to 2%. Its less than what i can get manually mining and a bit of trading on top.

I will keep using it for awhile til am no longer as busy then return to manually mining/trading.

Re: R290 crossfire, undervolted by 25mV, stock clocks, getting ~820 kH/s with one card with Elpida vram, and ~840 kH/s with other card with Hynix vram. I have tried running them at 1ghz core and it went up to 868 kH/s on the Hynix card but went DOWN on the Elpida card.. its such a stupid card I CBF tweaking it further.

Re: above mod edit
Never been to 4Chan and never plan to (I stole that itshappening.gif from a gun forum), but I digress.

It seems that with the recent uptick in BTC/LTC prices relative to USD, people are pricing altcoins accordingly and most of them have taken a beating in recent days. DOGE is about half the price of last week and LOT has dropped by 1/3 as well.

That said, the choices on CoinedUp alone have gone from maybe seven currency pairs a month ago to 27 as of this post. Not sure how long the market will continue to grow but it seems like for the foreseeable future there are going to be trading opportunities due to pricing uncertainty...

I thought this post about the tax treatment of cryptocoin mining is interesting to me, and relevant.

http://www.reddit.com/r/Bitcoin/comments/1uccfz/i_am_a_tax_attorney_here_are_my_answers_to_the/

I realize that some may have political opinions about taxation, tax laws, etc. and it's not my intention to turn detract from the technical discussion in this thread by posting this. I thought it might be relevant to some here and interesting to most.... so please (pretty please) don't go off on some sort of political discussion. Just read it if you think it's interesting or relevant and ignore it otherwise.

Yep that is a helpful post. Though he doesn't deal with mining and using mining hardware as part of your cost basis until the comments.

Supposing that you forego any deductions for depreciation of mining hardware, it's not unreasonable (per that tax attorney) to fold all your hardware costs and power costs into your cost basis for the bitcoin you sold. Which means you can keep your cost basis indefinitely zero by continuously purchasing hardware (as long as you mine with it).

Take a deep breath and try again.

I think I said that and it appeared in the wrong light. I've plenty of money of mining and buying/trading. I've had a great time for the most part, but for the life of me I can't get these to hashrates people report. Not sure if people are generally full of shit or it's just high end of the spectrum rates or getting lucky with their cards.

Venting is my way of taking a deep breath.

Back on relevant technical discussion:

I've got a Gigabyte MicroATX motherboard + A6 APU w/ 2x Gigabyte WF3 7950's. Each @ ~560 k/h., temps are 76C/56C. '--gpu-powertune -50,-50' lowered power consumption about 100mV on each card. Have a kill-a-watt on there now. Pulling 550 watts. I will lower that further once I get it to load off of USB and disable the SATA controller.

Other is some old Asus board (old Athlon dual core) and it's got a Sapphire 7970. Pulling 580k/h right now. @ about 74C. Probably about 400 watts. Undervolted 125mV.

I have a 7790 in a little ITX SteamBox I built doing 190 k/h, but I have a feeling it's costing me more than benefiting me. I haven't bothered to really even measure wattage on it.

If you put -50 for powertune, won't it reduce clocks as well, thereby reducing hash rates?

Catcoin set for a fork soon. Here we go! Mining Catcoin right now.. Just switched over from Dogecoin.

Based on the litecoin mining hardware samples, yeah, your samples seem a tad low, especially that 7970.

Since I started with a 7850(985 MHz core clock, 1375 Mhz memclock, ~343 Khashes/s), and it responded best in this manner, I always first simply use cgminer without any special settings for -g, -w(or w=256), or thread concurrency and start with just overclocking the card carefully and upping the intensity. That get me the 620 Khashes on my 7970.

You might want to open up your case and turn your heat down to 68 degrees or something. My 7970's heatpipes can actually burn someone. Also, it could be that the thermal compound isn't properly applied on your cards.

dammit I think my rig keeps tripping my circuit breaker. Been working fine for a few days but yesterday I ran it non stop and now keep tripping the circuit breaker within the hour or so.

Any suggestions? Don't suppose watercooling would help with the Wattage.

May have to remove one 290 and run in the other bed room.

 

[pandemonium]

That circuit is overloaded, since it may have other [larger] appliances on it as well.

If it's that serious, you may need a dedicated circuit for your mining configuration.

FYI: water cooling will only add to the watts consumed.

Edit: depending on the age of your house and the wiring, you may want to have an electrician inspect the wiring and test those circuits for you. Typically you shouldn't be tripping the circuits in a modern house unless you have a very large farm there.
