Cryptocoin Mining?

[Mir96TA]

NameCoin is a waste!

Have you guys tried changing voltage with cgminer settings? I can change the memory and core clocks but --gpu-vddc does not alter the voltage no matter what I set it to. This is with my HD7950 in the signature.

name coin is not a waste if it mines them free while ur mining bit coins.

Never tried, I use msi afterburner for voltage adjustment.

It's a browser based miner that is extremely simple to set up. You create an account, punch in your wallet address, and push "start minting". It worked great for me when I was mining. There is basically nothing to configure and as far as I could tell it was just as fast as other apps like DiabloMiner.

This is working great on my system, thanks for the tip bro! Getting ~420+ Mhps on the Tahiti in sig :thumbsup:

I just use Afterburner. Not really a fan of letting a program that was not really designed in the first place to control GPU settings do that for me. Afterburner is designed to control the GPU, so I use that to do what I need. Unless that's for Linux or something...

I'm glad it worked out for you.

The other half is that all the other exchanges suck too.

Apparently bitfloor is having some bank trouble.

lol my $100 "test" deposit just showed up there too.. Now it's stuck there

Yep, BTC difficulty has jumped and daily profit on the best tuned single 7950 is woeful now!

LTC diffculty up too to 364.36. However for me personally on my 7950 its still 1.5 x as profitable to mine litecoin than bitcoin.

I use this calc here, not sure where it pulls it's USD prices from but they seem quite accurate.

http://allchains.info/calc.html

For BTC I run 500m/h @ 200 watts @ $0.18c kwh which gives $1.65 a day profit after 3.5% loss for pool fees and stales.

For LTC I run 0.625m/h (625k/h) @ 280 watts @ $0.18c kwh which gives $2.46 a day profit after 3.5% loss for pool fees and stales.

Basically predicited to mine out only 0.027 BTC but 1.665 LTC which is 0.0395 BTC.

Unless the LTC price crashes relitive to BTC, and they seem locked,or the pull LTC/BTC conversion for all exchanges, you would me mad to mine BTC on a GPU now.

TRC is another thing though becuase of it's dynamic difficultly, some 24hr tests needed to determine daily mining rate ( i estimate 8-9 based on a 7 hour test run) using the same GPU settings as BTC. Once TRC overtakes LTC as the most profitable altcoin then this should remain stable because the Devs have altered the TRC blockchain to dynamic difficulty to foil BTC ASIC miners killing it with hashrate. :sneaky:

Guys, when I checked my Sapphire 7970 OC Dual X VRM temp, one is at 60C and the second one is at 105 @_@.
I even underclocked the GPU by 100Mhz and the temp would go down...is is okay or VRMs are meant to run that hot? Also how stable is LTC coin mining nowadays and i have a combined hash rate of 2400 Mhash and is there a calculator that predicts how many LTC I will get per day?

 

[hokies83]

Id remove the cooler on the 105c card and see what is going on with it..

The air from the fans should be blowing on it cooling the Vrms... 105c sounds like it is not geting any air.

I think I found a buyer for my GTX 670, so my shopping for a 7950 or 7970 has renewed in earnest.

Unfortunately the 7970 that Phillipma suggested is now OOS at reasonable prices.

http://www.ncix.com/products/?sku=70111&vpn=AX7970 3GBD5-2DHV3&manufacture=PowerColor

Does anyone have experience with this card? Is it voltage unlocked?

If anyone else can recommend a good deal on a quality 79x0 in Canada, I'm all ears. All I know for sure is that I don't want an XFX.

 

[Chiropteran]

Not familiar with the Canada market, but I'd get either this:

Or the Vapor-X Ghz edition variation of it.

Yeah, that is the one that phillipma recommended too.

I just got $330 for my GTX 670, so I'd prefer not to spend more than $400.

What about the Sapphire 7950s? How much lower will they hash compared to a 7970?

EDIT:
This one is voltage locked, but it has the connectors I need and good reviews. Decent price for Canada too.

I haven't used a 7950 myself, but there is this for a general idea:
https://en.bitcoin.it/wiki/Mining_hardware_comparison

Seems to indicate 450-500mh/sec should be possible, those numbers might be based on an overclock.

 

[Subyman]

I think people making profit calculations using a current exchange rate are not properly determining their profitability. 1-2 months ago mining Litecoin would have been dumb if using that calculation, but if you would have looked at Litecoin's potential to go up then it would have been very beneficial to mine LTC instead of BTC back then. Other factors need to be taken into account such as the coin's potential for growth and the diff's potential for growth.

I stepped off the BTC train and instead mined LTC when the diff was very low because I could get 100's of coins a week with a large potential to grow.

What I'm saying is that you need to look at much more than a snapshot of the current market and decide for yourself if you see growth in the future and, just as importantly, judge which has more potential for growth.

Bitcoin was at $30 when LTC was at $0.27, to roughly get the same profit BTC would have to grow to $300 while LTC only has to grow to $2.70. BTC crashed at $250 back to $80, LTC is holding steady at $2.00. Therefore magnitudes need to be considered as well and its effect on market psyche. When new cryptocurrency is nipping at Apple stocks and they don't pay dividends then you know you are ready for a crash .

My7950 does 430 Mh/sec stock. Seems low to me. It's stock core is 900

Use this. Estimate 3-4% for pool fees and stales, swap your btc mhash for LTC k/hash and up your BTC kWH use by about 20% minimum. Reason being is the LTC mining is GPU memory heavy so you have the GPU memory maxed our and volts upped. This uses more power.

burn's pool can get stale heavy often. I'd probably go up to around 6% considering stales + fees.

Personally I have never mined with them, I just like their calculator! I use Give-me-ltc.com and find them excellent, and stales only run at a steady 1.6% level.

Yeah, agreed. give-me-ltc has a calculator too - and he says he got it from ltc.kattare.com.

But yeah, give-me-ltc has fees, but stales are very low.
Burnside seems like a great person, but his stale rates are nearly always pretty high and sometimes ridiculously high. I want to like his pool but I'd rather pay a fee for <2% stales, than have ~10% stales that sometimes jump to >15.

LTC have been consistently more profitable to mine for some time now. Remember LTC difficulty in January was only a tenth of what it is now.

My 7950s do 625 MH/S with my Overclocks. And -v -w 256 -f1 Flags.

Also since the DDOS attacks im making like 50% more btc then before the atacks??!! LoL

From 0.005 up to 0.008
