Cryptocoin Mining?

190-200 kH/s @ 150W

Woof, better shut that thing down, think of the trees man!


But in all seriousness, that is some pretty awful kh/w :thumbsup:

just like any market, ups and downs.

This is the worst day for bit coin in a while. I hope it rebounds.

Glad I took the sell as I got approach over the past 2 weeks. LiteCoin is also dropping hard right now. All coins are. This could be the big correction.

Is there any reason not to use Mt Gox? It seems like rates are much higher there than places like coinbase and BTC-e.

Withdrawing money is very difficult for Americans, which leads to higher prices for BTC.

As I've said repeatedly, the power costs DO NOT MATTER if you are currently paying for electric heat. All you are doing is substituting a heater that does calculations for a heater that doesn't do calculations. The only reason NOT to mine (given above scenario) is if you are worried about wear and tear on the fan.

This is only true up to a point; you can produce more heat than you really need. And seasons change; heat is a negative during the summer, as our Australian friends are currently experiencing.

Mining actually DID kill my old 7970's rear fan which was so far gone after several months that I had to sell it (not worth the RMA headache). I also got a 7790 later on and the fan got louder and more erratic over time with mining loads.

Mining strains other parts of your system as well, such as power supply, power supply fan, and case fans. The CPU and mobo and RAM are also strained beyond normal usage, because they are dealing with 24/7 usage at elevated temperatures from all that heat sloshing around in the case.

When you mine, you accelerate the degradation of your entire system, with especially high degradation of the video card's GPU and fans.

Thank you. I guess I'll keep using coin base. They've been reliable.

This is the first time BTC has crossed 12-hour support during the entire rally. It's a good time to sell if you haven't already.

900/1250 seems to be the sweet spot for my MSI 7870, getting 375kH/s while also getting ~50kH/s with my i5 3570k @4.2GHz CPU temp is only 50*C

 

[Smartazz]

Bitcoin is stabilizing. I was very close to selling. Anybody know the best way to convert name coin, litecoin and/or prime coin into bitcoins or USD?

 

[BallaTheFeared]

BTC-e

Is it easy to use as a US citizen?

I got the below gaming rig.. Is it worth figuring out how to mine today?

Yes, if you don't mind the heat and noise 24/7.

Yes, if you don't mind the heat and noise 24/7.

My MSI 7870 runs fairly cool and silent while I am mining on it. My 7870 XFX double D gets really hot and loud though.

It would definitely be worth mining on two 7950s. You could easily rack in at least $500 in the first month if you mine 24/7 according to this calculator and 1200kH/s which is about average or on the low end for two 7950s.

That assumes price stays where it is and doesn't collapse and that difficulty remains constant, and given how all the stores sold out of Radeons over the holidays and how it takes a few days for things to get delivered and set up, I'd say we're in for one HELL of a difficulty bump real soon. If difficulty doubles, revenues halves.

 

[Kevmanw430]

Anyone else using Multipool? It monitors a bunch of smaller cryptocurrencies for profitability vs. BTC and switches your miner between them automatically based on which is the best at that minute. Seems like a great way to maximize profitability.

Nwo, I'm getting aobut ~380KH/s on my 7870 with 900/1450. What are your other settings? Seems like I should be more than 5KH/s faster with 200MHz more on the mem clock.

Yeah. I've been mining LTC for months even though I know mining one of the other alts will likely net more of a profit. Just ordered a 7970 and will look into mining other coins after I that box setup.

Looks like prices stabilized from the crash earlier. Looks like the high values are here to stay. No more crashes that low unless there is an attempted ban from the US government or something.

There is a way to set this up per miner with stratum I believe. Wow.... just checked out multipool. Setting up my account on that when my new card comes in! Thanks for the tip! :awe:

I will double check the settings on my MSI card for you tomorrow. But from my experience with 7870s, higher clock speeds may actually give you lower hash rates. For some reason GPU clock speeds do not give a linear hashrate increase like they do for the CPUs. For CPUs, I know that if I bump up the frequency by 100MHz, I will gain an extra x hashes per second... That is definitely not the case for GPUs, at least not the 7870s I have experience with.

For instance, I was just running 950/1250 on my XFX card and I was getting 310kH/s... when I decreased the core to 900, I went back up to my (best) 325kH/s... For the XFX card all I am using:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

cgminer --scrypt -o stratum+tcp://us3.wemineltc.com:3334 -u nwo75200.1 -p 1010 --thread-concurrency 14208 --lookup-gap 0 --gpu-engine 900 --gpu-memclock 1250 --gpu-powertune 0 -w 256 -I 17 -g 1

Just an update, for all those with a 290 unlock-able or not: I was getting issues with mining as a 290x, so I went back to stock bios. Now, not only does it seem more stable, but I get higher hash rate! Using the same settings, I get around 820 kh/s. Not sure if this was due to core instability, or if for some reason 290s do better right now than the 290x.

 

[Pandora's Box]

Hmm I appreciate the help offer very much! My hashrate seems a bit low, but then I have seen them all over the place on the net from 500kh/s to almost a Mh/s. Right now, just looking at GUIminer, I'm at 729 kh/s.

As of now I am running 290x core unlocked at stock speeds; the card doesn't seem to be a great OCer.

My settings are TC=32765, vectors=1, GPU threads=1, worksize=512, intensity=20.

I tried putting the extra flag lookup-gap 2, but it would fail to connect and get any work.

Also, I replaced the CGminer folder that came with the guiminer-scrypt to the latest, 3.7.2.

Used this guy's settings pretty much...https://forum.litecoin.net/index.php/topic,6842.0.html

Shmee, are you still using those settings on your 290X? I have 3 290's coming in on Tuesday, wondering if those settings would work well for them.

Its because mining thrashes these GPU much more than gaming, causing massive power spikes which means Powertune kicks in and throttle clocks. A R290X on auto settings with its extra shaders are going to consume much more power so it will throttle. You can try your R290X bios with +50% powertune and 100% fan speed (temporary) to test and see the clock speed during mining.

I am still getting crap results on the 290x regardless of what settings I am using. I will try flashing the Asus bios on my Sapphire card later and see if it helps any. Will also be doing a fresh windows install soon so will be able to see if that helps as well.

I don't think thats the only issue though. When I had it unlocked, I had +50% powertune, and a custom fan profile, and yet there were stability issues and what not at stock settings while mining. I also heard that some people with real 290x's were having issues as not getting very good hash rate compared to 290 cards, so I wonder if it is partly poor miner optimization for the X version.
