New people please read this. [upvote for visibility please]
I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can. Preface Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here. If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier. Mining. What is it? Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section. Mining Hardware While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much. Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it. So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy. Should I mine? Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats PCPartPicker part list / Price breakdown by merchant / Benchmarks

Estimated Hashrate (with GPU overclocking) : 1900 KH/s Hardware Fundamentals CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with. RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory. HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats) GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like. PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption. MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less. PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied. When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info. Mining Software Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head) Mining Pools Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself. How do I connect to a pool? Most pools will give you a tutorial on how to but the basics are as follows:
Signup for a pool
Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine: Hardware cost: The cost of your physical hardware to run this whole operation. Power: Measured in $/KwH is also known as the operating cost. Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon. Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously. Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones. coinwarz I like this one cause it is simple. The fields are self explanatory. Try it. bitcoinwisdom I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account. Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it! More Below.
Not So Brief History of my Radeon HD7950 ASUS Direct CU II
Sexy Beast Pic 1: https://i.imgur.com/dQC90.jpg Sexy Beast Pic 2: http://www.legitreviews.com/images/reviews/1839/7970-dc2-top.jpg ASUS HD7950 Direct CU II. This card mined 1.5-3 BTC Bitcoin for me. Started with Bitcoin, then mined Litecoin in the early days of Litecoin GPU mining. Had 2 X ASUS HD7950s running 24/7/365 at the time. Each did about 3 BTC each total, and then switched full time to LTC Litecoin. This card was also used for CS gaming, 3D rendering, real time graphics, some video editing, and yes, yes more mining! Still RUNNING today! AMD FTW! After some test mining Litecoin for a month, I quickly built 2 more Radeon GPU rigs to mine LTC. Total 3 rigs 12 cards. Blazin! Then in Dec 2013 this setup mined millions of Dogecoin in a few days shortly after launch,... I remember raking in over 300-500K DOGE / day at full throttle. We setup our own Doge Pool, and DOGE miners were chatting on IRC: The Excitement was REAL! This fun SUCH DOGE WOW time was cut short by a massive ice storm that knocked out the power for a week. So no more DOGE. When I got back online diff was up and production down to 30K per day or less, but DOGE price skyrocketed so I sold DOGE for a good profit. I remember donating DOGE to send the Jamaican Bobsleigh Team to the 2014 Winter Olympics, and they made it to Sochi! What a time to be alive! I was a DOGE Millionaire by then... Such Card, Much DOGE! WOW! Shortly after that, around March 2014 the second HD7950 blew some caps and need to be sent to ASUS for service. ASUS promptly replaced the card under 3 year warranty and shipped a replacement in two weeks. Mining frenzy continued with FeatherCoin and PotCoin. DGB Digibyte was the next chapter! ;] In summer 2015 I decided to part with one of them. Sold on Kijiji to a local fellow gamer that had his video card blow up, and didn't have enough $ to buy a new one. Gave him a deal. The guy was so happy, it was like Xmas for him. I knew that this ASUS 7950 will have a great home. So I said Good Bye to engine #2. When this card is retired I will box it for display. Been through so much with it, still my number 1 engine. When something is this good, you keep it in the Fam'. Still works great. Thank you ASUS & AMD for making kick ass products! Over & Out! Peace! ;] Jamaican Bobsleigh Team https://media.coindesk.com/uploads/2014/01/jamaica-bobsleigh.png 25 MIL DOGE + 35 BTC raised for Jamaica Bobsleigh Team http://i0.kym-cdn.com/photos/images/newsfeed/000/682/940/6e9.jpg Jamaican Bobsleigh Team Raises $30k in Dogecoins, Jan 20, 2014 https://www.coindesk.com/jamaican-bobsleigh-team-raises-30000-dogecoins/ DOGE Meme in HD: https://www.geek.com/wp-content/uploads/2014/01/dogecoin.jpg
I've had this card since I built my main desktop. I upgraded in December, so it's just been mining since then. Never been above 65C. Still maxes out all my games at 1080P.
Brand New Sealed-in-Box Logitech G710+ Brown $80 local cash only.
I bought two and only ended up using the one. Excellent keyboard. Cherry MX Brown Switches, so no stapler sounding keypresses. White LED lighting with independent control of WASD & the rest of the keys. 4 brightness levels + off. Volume wheel, mute button, & media keys, plus 6 macro buttons.
A disgruntled opinion/rant regarding Bitcoin/Litecoin/etc. mining and the enthusiast GPU market.
Back in June of 2012, I very eagerly built my rig with a single Radeon 7950 in anticipation of crossfiring it down the road with a 7970. Now that time has come, and in my efforts to procure what I had anticipated to be quite the bargain, I am absolutely flabbergasted by what I discovered. There's not a decent Radeon 7xxx in sight, and the 7970s that I could find are going for upwards of $400 USD! This is simply unacceptable for a two-year-old card, and even more unacceptable when considering that these very cards were (according to this guide) retailing for $269.99 this past October! That is nearly a 50% price increase in just two months at the very end of the card's life, and just after the universal price drop to all 7xxx units complimenting Nvidias launch of their GTX700s. I hope I'm not being oblivious/naive here - and please correct me if I am - but I have NEVER seen that happen before with ANY consumer product (that is being replaced by a new revision). Of course I know the economic rules of supply & demand: There are lots of people who want these few cards, so AMD can afford to boost the price on them. However, this is pretty unreasonable considering AMDs focus on the new R9 chips, which are the new supply. The perpetrator here is the growing trend of Bitcoin mining. The computing power and efficiency of AMDs GCN architecture is extremely good at mining for this "magic internet money." A growing amount of people are noticing this, and thus demand for AMDs chips has blown up like crazy. It's even become a goddamn selling point in advertisements. I understand that the processing power of these cards can be very well harnessed for coin mining, and that's fine. However, for those of us enthusiasts that enjoy using our video cards to push pixels, I anticipate this trend to continue putting a strain on the market and our wallets. TL;DR: I'm butthurt about last-gen AMD GPU prices being unreasonably high, and get mad (within reason). *edit: AMD is not boosting prices, retailers are. Thanks to Shrederrr for clarifying. **edit: To all the people suggesting that I sell my 7950 on the secondhand market, thanks; that is a good idea. Honestly the solution didn't cross my mind at the time of making this post - I was still reeling from the unbelievable prices and frustrated that I wasn't able to follow my planned upgrade path. This unprecedented Bitcoin/Litecoin phenomenon caught me by surprise and it saddens me somewhat to see these enthusiast GPUs being used in such a menial, greedy fashion. It's like seeing a Ferrari V12 powering a backup generator for a t-shirt factory. Sure it's being put to good use, but it's just...not right.
[Upgrade] Most cost efficient upgrades for a £250-500 budget? Unsure :(
Hi guys. I'm in a bit of a dilemma here, as my PC is still performing fairly well, but the FPS is low in the more modern games and as I play competitively it's important for me to keep a high FPS. I am not sure whether it's better to 'wait it out' and spend £1000 later on, or upgrade a few key components now. Any advice? Here are my specs currently: CPU: Intel Core i5-4690k GPU: AMD Radeon HD 7950/r9 280 RAM: 8GB Kingson DDR3 SDRAM (2x 4GB sticks) MOBO: GIGABYTE Z97P-D3 .... I'm guessing upgrading the CPU or GPU is the next step, but I have heard things about GPUs being overpriced due to bitcoin mining at the moment, and I'm not sure out of those two which is likely to be more of a bottleneck. Any advice guys? I'm also unsure whether it's better to spend, say, £500 on a new GPU, or £200 on a CPU and £300 on a gpu.
This is an all-purpose build that I put together slowly over the past year. It started out as just an HTPC, but ballooned into a gaming and bitcoin mining system. What's not listed in pcpartpicker is an additional HD 6850 connected by a PCIe x1 riser for bitcoin mining. The total hashrate of the system is 780 MH/s. Mining has been going full-on for about 4 months now and about a 1/3 of the cost of the current system has been paid for. It probably won't continue at this rate if difficulty goes way up with the asics coming out, but a 1/3 of the cost already is still a lot. The i5-3450 and 7950 are a great combination for gaming. FPS on ultra detail on BF3 is 40-60 on a 1080p HDTV with AA/MSAA at their lowest settings. Pictures PCPartPicker part list / Price breakdown by merchant / Benchmarks

Hello Redditors! I was referred here by a floor mate of mine, she said, 'Reddit is the place to go if you ever need ANYTHING.' She made sure to emphasis the anything part. I recently bought a complete desktop off of a fellow on Craigslist. (The guy I bought it off of is in the United States Army, and he had to literally sell it quick while he was in town. He was being shipped off to California, and was just going to throw it away if he didn't sell it.) He was asking $75.00 for the complete setup, which I thought was decent. I emailed him an offer of $50.00, knowing his hardware was a little dated. After approximately 12 days of going back and forth, I finally was able to meet this guy and complete the exchange. He gave me a monitor, tower, router, mouse, keyboard all for $40.00; he shaved $10.00 off for it being Christmas and all when we met. Here is a little more detail about each of the individual items. The Monitor - It's an eMachines monitor, running 1366x768 with a 60Hz refresh. Great condition. The Tower - It's an eMachines ET1331G-05w Model. This tower is different though, it has 2 HDDs (750GB and 200GB) and a discrete graphics card! (ATI Radeon HD 5450, to be exact.) It's running Windows 7, and I haven't used it for anything besides general web browsing and light BitCoin mining. The Router - It was a brand spanking new NETGEAR N900 Wireless Dual Band USB Adapter, and it works great! (I was looking in stores, and it was $60.00 or so brand new!) The Keyboard - I believe it to be the stock eMachines keyboard, nothing special. It has the Volume controller at top, with a sleep button on the right. The Mouse - It's just a Microsoft optical mouse from what I can tell about it. So, for a grand total of $40, I don't believe I did that bad for what I got. Allow me to get back on track with why I posted here... My friend told me that I'd be able to get help here with building a more up-to-date computer. She explained how it's cheaper and I'd get a better computer for my dollar. I saw that there was this part of Reddit -> /buildapcforme - I don't want someone else to build my computer for me. So, instead of going that route, I am going to propose a build and get some feedback on it. I plan on making this the central-hub for just about everything.... Gaming, Movies, Music, Work, etc... I run Photoshop, NetBeans, Eclipse, and so much more! Here is the AMD Build: PCPartPicker part list / Price breakdown by merchant / Benchmarks

First and foremost, this computer is intended to hold me over for the next few years until I am commissioned into the United States Air Force. Here is a list of different things that this computer will be used for:
Goldfarming. Wait! What's that? Well... goldfarming is where you run a "bot" (or macro) to obtain in-game currency. Then, with that in-game currency from the bot, I sell to the general public for good 'ole real-life currency, preferrably USD.
Gaming. Nothing too major, just something to do every now and then.
Programming. I am, and plan on, taking computer programming classes while I am here at college.
Now that I am done with what "society" has wanted me to do, by telling you the Gaming-Aspect of this computer's usage, I will continue.
Entertainment. Yes, entertainment. This includes, but does not limit to, movies, music, and whatever else your minds can think of.
I've also been thinking of running some BitCoin Mining/LiteCoin Mining in the background, figured it can't hurt. I know it's "late in the game," but it's whatever. I don't pay for electricity. (Either I am at home, where the MILITARY pays for my electricity, or I am at school, where the UNIVERSITY pays for it.) Any questions, comments, concerns, or general feedback? (Also, this is my last build. I am not building anymore, until I actually physcially build this computer.) The statement in quotations is not to discourage you from suggesting better parts. Try and keep the budget to $900, I'd like to not go much over.
Looking to upgrade GPU, trying to find the best upgrade..
Hi, I currently have an okay build right now, but my graphics card (Radeon HD 7950) is hand-me-down, and was used extensively for bitcoin mining before being handed over to me. I'm not sure about the life of the card, so I'm looking for something new. I don't want to exactly spend a lot. The card is pretty spectacular as it is, so I'm hoping for something of it's power or a bit greater. My price ballpark is ~$250, and naturally I'm looking for something that is good for gaming. Doesn't have to max out every setting, Medium at the least is fine for me. I don't mind switching to Nvidia, so as long as I can get the proper price for whatever performance I'm paying for. Any help?
So over the last week or so I've become more and more interested in starting up mining again (last done this years and years ago, bitcoin mining ofc) but I have to be honest I have forgotten pretty much everything. The technology has also moved on from back then when and I'm currently looking at getting a little rig together for about £800. 2x Sapphire Radeon HD 7950 3GB I've been looking at https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison to see what the average kH/s is and then calculating the gross profit on http://www.litecoinpool.org/calc?hashrate=1100&difficulty=153.16808633 Now I know that the difficulty won't stay at this rate for very long but from what I can see you can make the money back within a month? Surely I must be missing something here.

I recently bought a 2nd 7950 (same exact card) but have yet to put it in my system since i would need a more powerful power supply. My question is, should i sell my 7950's and use the money from that and what i saved by not buying a new power supply to buy a 780? I currently use my computer for a decent amount of gaming on 2 1080p monitors and also do quite a bit of video editing on Adobe Premiere CC (which takes advantage of dual GPU's). I should mention, I also have been considering Bitcoin mining, but do not know anything about it or if it is worth it. Power use is also a concern for me since I will be moving into an apartment not too far into the future where I will have to pay the electricity bill (currently live in a dorm where that is included) and I am kind of tight on money. So should I keep the 7950's and buy a power supply or sell them and get a 780?

Changes: 1) First change I had was i had a corsair tx750 and it was making quite an annoying coil whine. Corsair had very good customer service and accepted my RMA and had a new one back to me shortly. However instead of continuing to use that power supply I picked up the xfx on sale for around $89 down from its much higher regular price. I then sold the corsair to pay for new power supply. 2) Added some case fans. Added 2 blue coolermaster fans because there was a good sale on them. I'm not to focused on CPU overclocking anymore so i stuck them on the CPU cooler for a nice cool effect. Also added a delta fan. IT.IS.LOUD. But that's why you buy it. It creates a massive amount of air flow and i needed that for the summer heat. 3) Added sleeved cable extensions. These things are great! They allowed me to get my cpu power behind the mobo as before a 8 pin connector wouldn't fit around the top, but with the cord having a 4+4 instead, it was able to go through the back. Also allowed me to get the motherboard cable behind tray as the xfx's motherboard cable is very short. They look awesome and improve air flow. 4) Added a second 7950. I wanted to do a little bit of bitcoin mining so I decided to pick up a second card. As the card was running too hot i moved it down a slot. While i no longer have crossfire, temps dropped about 15C. Some advice: If you dont need something right away. Look for a sale! Sales saved me so much money on this build! Im glad i waited for sales instead of buying right away.

Which of these options would you suggest for my upcoming GPU upgrade?
Okay so I am planning to upgrade my graphics card, but would like some suggestions on how exactly to do it. Here are my current system specs: AMD FX-8350 @4.3GHz MSI Twin Frozr Radeon HD 7950 @1100MHz core and 1250MHz memory 1000W Coolmax PSU (yes, I know it’s a crap brand, but I’ve actually run 3 GPUs on it before, during my bitcoin mining days, so I know it can take a heavy load) MSI 890FXA-GD70 Motherboard 18 GB DDR3 RAM @1600MHz (yes, I know it’s a weird amount and I know it would be slightly faster if I took out the mismatched sets, but I would rather have the extra space than the slight speed boost) Here are the options I’m considering: 1. A new Nvidia GTX 970 – Total cost: ~$350. Advantages: latest-generation card with “4GB” of memory (even 3.5GB is still more than 3GB), latest and greatest features. Disadvantages: Possibly not fully compatible with DX12 (not 100% sure on this, but it’s something I’ve heard) 2. A new Nvidia GTX 780 Ti – Total cost: ~$420. Advantages: most powerful single-card setup I can afford. Disadvantages: older card means fewer features, only 3GB memory compared to the 3.5/4 on the 970, probably not fully compatible with DX12 (again, only something I’ve heard) 3. A second (used) Radeon HD 7950 – Total cost: ~$120. Advantages: very affordable, should be very good performance in games that have good crossfire support, supposedly will have full DX12 support (again, a rumor). Disadvantages: older card means fewer features, stuck with 3GB VRAM, games/applications that do not support crossfire well will see little to no improvement, buying a used card is a little risky 4. Two more (used) Radeon HD 7950s – Total cost: ~$240. Advantages: significantly more raw computational power than even a 780 ti, at a much lower cost. Disadvantages: same as one additional 7950 (except buying two used cards is even riskier) 5. A new R9 280 (to be used in crossfire with my 7950) – Total cost: ~$170. Advantages: quite affordable, should be very good performance in games that have good crossfire support, supposedly will have full DX12 support (again, a rumor). Disadvantages: stuck with 3GB VRAM, games/applications that do not support crossfire well will see little to no improvement, won’t match my current card asthetically (not a big deal) 6. Two new R9 280s (to be used in crossfire with my 7950) – Total cost: $340. Advantages: significantly more raw computational power than even a 780 ti, at a significantly lower cost. Disadvantages: same as one new R9 280 So those are the options. I am willing to spend as much as the 780 ti if it is worthwhile, but would (of course) prefer to spend less if a cheaper solution makes more sense. Something like a 980 or two 970s, though, is out of the question. I just can’t justify spending that much right now. Let me know what you think and if there are any advantages/disadvantages that I didn’t think of, and thanks for the help!

Hello guys, I am extremely new to this bitcoin mining and I had a couple of questions. My set up: 2 of HIS HD Radeon 7950s running at 800 MHz, 1250 memory clock cgminer 3.2 Questions: 1. out of box I am mining at 420mh/s at intensity 6. Is that good? It looks like this card can overall do about 500 out of box but my friend has told me he gets about 450 out of it.
What exactly is thread concurrency? What are some important arguments to put into the batch file when setting one up for cgminer?
Is it safe to overclock? If there is a way to overclock and stay at mid 70's for the temp, fans running at 100%, is it dangerous to do so? would the outcome be worth it?
Is there a way to overclock it and keep temps mid 70s?
Note: 1) The CPU is part of a bundle with the RAM and motherboard--the total cost of the CPU is the total cost of the bundle. 2) I own a different HDD and Monitor...however I could not find either, so I picked what matched closest. 3) I am on a $350 budget however, if I wait until June, my budget will increase to $450-500. 4) I hope to expand this PC in the future--ie by upgrading video cards etc. 5) The reason I am considering getting this PC now is because the deals I found feel too good to pass up. 6) I want a PC that can play new games such as The Witcher III. Edit: I currently own a decent gaming laptop that's bottlenecked by a 770m (also has 16gb RAM(overkill), a core-i7 2.4, and a SSD). Ideally, I want my desktop to better than this laptop--with the option to be up-gradable. Please let me know if you have any suggestions! I own a fair number of parts from my previous PC and Bitcoin mining rig.
