Sgminer 4.1.0 is very similar to cgminer 3.7.2, though there are some interface changes and also there are some extra features such as multiple experimental kernels to play with as well as some of the features found in the cgminer 3.7.3 kalroth edition such as xintensity and rawintensity modes besides the standard intensity mode form cgminer.If you are interested in trying out something different you might want to play with sgminer as it has some other useful features that are not available in the standard cgminer, the download link for the windows version is available below.– You can download sgminer 4.1.0 with Scrypt GPU suppor for Windows OS here… In: Mining Software Tags: cgminer, cgminer 3.7.2, cgminer 3.7.2 windows, cgminer alternative, GPU mining, litecoin gpu miner, litecoin gpu mining, rawintensity, scrypt mining, sgminer, sgminer 4.1.0, sgminer 4.1.0 download, sgminer 4.1.0 windows, sgminer 4.1.0 windows download, sgminer download, sgminer windows, sgminer windows download, windows scrypt mining, xintensity Read More (9) Comments Download cgminer 3.7.3 karloth with GPU support for Windows 6, Feb 2014 If you are mining Scrypt crypto currencies such as Litecoin or maybe DOGE, then you are most likely using cgminer as a mining software or something that relies on cgminer as a backend.

The author of cgminer (Con Kolivas) however seems to have decided to continue support of cgminer only for ASIC mining for SHA-256 cryptos such as Bitcoin and version 3.7.2 is the last one for cgminer to support GPU mining for scrypt crypto coins.best bitcoin ticker iphoneFurthermore the windows version of the last cgminer to support GPU mining has been removed from the official download location, you can however download cgminer 3.7.2 with GPU support for windows here.bitcoin whale clubMore importantly, there are already some alternatives that are based around the original source code of cgminer 3.7.2, but add extra features and offer improvements that are not found in the original software.ethereum april 24thOne such version based on cgminer 3.7.2 is Martin “Kalroth” Danielsen’s cgminer 3.7.2 that he calls cgminer 3.7.3 in order for the users to be able to differentiate between the original and his version.diy bitcoin mining card

In cgminer 3.7.2 kalroth (cgminer 3.7.3) he has made changes to the visual interface to make it more user friendly and functionality that can help you squeeze a bit more performance out of your GPU mining hardware.bitcoin/litecoin cpu minerSome of the notable differences include support for multiple pool load balancing, implementation for idle state for GPUs when there’s no work, two additional modes for controlling intensity – xintensity and rawintensity for additional performance, faster failover pool switching back delay and interface improvements such as uptime status or percentage of rejected shares and so on.bitcoin suedoisDefinitely something to try and see if you like this version of cgminer better than the original 3.7.2.bitcoin kaufen amazon– You can download cgminer 3.7.3 karloth with GPU mining support for Windows OS here… In: Mining Software Tags: cgminer, cgminer 3.7.2, cgminer 3.7.2 windows, cgminer 3.7.2 windows download, cgminer 3.7.3, cgminer 3.7.3 windows, cgminer alternative, cgminer for windows, cgminer gpu, cgminer gpu download, cgminer gpu support, cgminer litecoin, cgminer scrypt mining, Con Kolivas, download cgminer, download cgminer 3.7.2, download cgminer 3.7.3, failover pool switching, gpu miner, GPU mining, kalroth, litecoin gpu miner, litecoin gpu mining, Martin Danielsen, multiple pool load balancing, pool load balancing, rawintensity, scrypt mining, windows scrypt mining, xintensity Read More (2) Commentsis litecoin easier to mine than bitcoin

In my previous Reckoner feature about Litecoin, I came to the conclusion that I had three options on the table at that stage of my experiment mining the crypto-currency: Option 1 – sell up and cut my losses.litecoin guide gpuOption 2 – keep mining at my current rate.Option 3 – buy more rigs and mine even more Litecoin with the hope that the price rises.Option 1, the path of least resistance.That’s the choice I ultimately ended up at.My Litecoin mining adventure wasn’t profitable and —if I’m honest—a waste of time.To redeem something out of the experience, I can at least share with you what I did wrong.If you are thinking about mining Litecoin or some other sort of crypto-currency, you can learn from my mistakes.The main thing everyone wants to know is “how much money did you lose, man?!”Let’s cut to the chase.Which is a total spend of $21,586.02.That puts me at a total loss of $8,183.24.

However, I do have 894LTC in my wallet.The current price of LTC right now is hovering around $2.50 (ugh), which means if I was to sell my entire LTC stash, I will have lost $5,948.24 all up.A good scenario is the price of LTC maybe hitting $5 once it’s announced on Mt.Gox (see their blog post which addresses this further).Which means, realistically, I will have lost $3,713.24 in total.If I was to sell that LTC for $9.15 per coin, I could break even on the whole thing.If I sell for $10, I’d make $756.If I sell my stash for $72.50 per coin, I’d be able to buy a sweeeeeett Mercedes Benz A250 Sport.Yeah, that isn’t going to happen.I was naive enough to think that the price of LTC would grow so quickly, that it could meet the minimum repayment on my card and cover the costs of electricity, rent & an internet connection.Unfortunately, this did not happen.I see now—with the benefit of hindsight—that this goal was unrealistic.I totally underestimated the sharp rise in mining difficulty too.

I knew it would rise, but not at the rocketing rate it has.Between April and August, LTC mining difficulty grew by 437% – that’s insane!My setup could have been more refined.I could have been running rigs with 5 cards per motherboard, resulting in a slightly lower initial setup cost and slightly lower power consumption.I could have also flashed the graphics cards’ BIOS (and hence, underclocked the GPUs) for a good balance of power consumption and performance, ultimately saving more power.With 7×5 card rigs, I would have spent $12,502.23 on gear and $1,910.67 on miscellaneous setup equipment.This would have saved me a total of $1,644, which at the end of the day would have been a noticeable difference.There would have been a small decrease in power consumption by having less rigs with more cards, but not by a lot and it’s hard to work out the exact power usage in the real world, especially after system tweaks.Let’s say I achieved a 10% reduction in my power consumption — a generous estimate based on the result of GPU tweaking and rig consolidation.

That would have made my power bill $3,796, instead of $4,218, decreasing my loss by $422.Tweaking the system and consolidating my rigs would have made a difference (to the tune of almost $2000), but not that much of a difference in the overall scheme of things.I still would have lost over $1,000.The key to crypto-currency mining (in Australia at least) is cheap power.Many of the people who purchased my gear are mining Litecoin and other coins, and when I asked them how they’re justifying the low profitability, they all said said they’re able to snag free electricity from somewhere.Normally stashing a few rigs at work, hoping nobody notices (hah).Good luck to them I say!If you can find free power, here’s how it breaks down: Spend $14,500 to set up a farm that should generate around 600LTC month.If you don’t have to pay for power—and assuming the LTC rate of difficulty increases at the same rate—you should have accumulated around 7200LTC.If you end up selling that LTC for say, $6 a coin, how much would you make?

Turn around and sell the gear for at least half of its original value, and that number rises to around $35,000.Assuming your source of free power doesn’t disappear, or find out and call the police for stealing… But what about solar power?The sun gives us free electricity!Let’s use it to power our Litecoin farms!Over the course of a year, our 30x GPU Litecoin farm will use 73,634kWh of electricity.Charged at 18.225c/kWh (still the cheapest power I can find in Australia), the annual power bill will be $13,419.A solar system with enough average peak output to supply 8400W of electricity would cost about $10,000 (you can get 10kW systems installed for $10k these days, cool!).Solar panels that output 10kW will be able to supply all the power we need!Spend $10k to save $13.5k and the panels will last for 20 years giving out free electricity!Let’s go buy solar panels now!!!Don’t get too excited, though.There’s a few harsh realities of solar power we need to step through.First of all, the sun doesn’t shine 24/7.

At night, we’d need an alternative power source.Normally that’s the grid, but you could also install batteries.If you do, you’ll need enough of them to power 8400W for the time when the sun doesn’t shine, and then enough solar panels to charge the batteries and power the farm itself.You’d be looking at just $25,000 for the panels, let alone the insane amount of batteries you’d need (probably 40 of the biggest deep cycle batteries you can find, which will set you back another $35k).Spending $50,000 doesn’t make sense.There’s wind power, which if you’re in a windy enough area, can supply power at night, but a 10kW turbine is huge and will set you back $20k easily.Good luck getting a permit to put one up anywhere in Victoria too.Thanks anti-wind farm nutjobs.So the only real alternative is to get a discount on our electricity use by using solar when it shines brightly to give 8.4kW of power, then supplementing it with grid power when there’s not enough light.Solar panel output varies greatly depending on the amount of sunlight.

Take these PVOutput stats from a 10kW system out in suburban Melbourne.The 10kW solar panels only generated 11,350kW of power over 12 months (there’s a few days missing, so I rounded the number up).Our farm needs 73,634kWh of power per year, so there’s still a shortfall of 62,284kWh – leaving us with a power bill of $11,352.All we will save is about $2,000/year.In other words, it would take 5 years of mining to pay back the cost of the panels and even once the panels are paid off, you’re still only saving $2,000/year.Solar panels are great and every home should have them, but as far as Litecoin mining goes, unless you’re in for the super long haul, I wouldn’t bother.There’s always an opportunity cost involved with this sort of thing.What else could I have done with the same resources and what would have been the result of that?I can’t go back in time to change what I’ve done, but it’s interesting to see what could have been.I whipped up a few spreadsheets to either justify my actions or remonstrate myself for wasting money.

So I guess losing approximately $3,800 overall isn’t so bad.Investing in shares like banks and mining seems like a good idea to be honest, especially since how they’re so protected by the government in Australia at least.Would I have done it instead of LTC?Probably not 🙂 It’s pretty obvious that if you can score free electricity, get mining Litecoin NOW.You’d be dumb not to.If you are a bit less risk averse with your investments and an interest in crypto-currency, take a look at these Australian guys making a Bitcoin mining ASIC device.It sounds really good, and particularly if you’re also in Australia, as you can catch up and talk to the people making it – they seem to be much more transparent than the other ASIC hardware vendors out there.There’s also the bonus of Bitcoin being a bit more legit and more ecosystem and culture around it than Litecoin, which is nice.That’s pretty much it for me in regards to crypto-currency.I don’t really intend to write any further regarding Litecoin or Bitcoin in the near future.
