Litecoin mining / Re: New rig opinions?
« on: March 06, 2014, 09:08:30 PM »
If you are looking to maximize hash rates, get the least amount of components necessary to get mining. I would recommend a budget build with 3x R9 270 cards like this:

It looks great and is very similar to this 6 GPU guide that thousands of miners have used successfully:
http://www.coinminingrigs.com/how-to-build-a-6-gpu-mining-rig/


The only thing you might want to be careful of is whether your household circuits can handle the load. Also, be sure to space the cards out enough and add supplemental cooling (box fan or similar) if needed to keep your card temps down. Under-volting the cards helps with heat as well.

Litecoin mining / Re: [Guide] 6 GPU Litecoin Mining Rig | 6x R9 270
« on: December 27, 2013, 05:12:40 PM »
Completely updated the 6 GPU guide today with the following changes:
  • AMD R9 270 GPU's (450Kh/s). The 7950s are impossible to find and other alternatives are overpriced. The R9 270 provides the best value currently. Low power usage (175 watts/ea when under-volted) also allows for a
  • cheaper 1300 watt PSU.
  • Motherboard changed to ASROCK H81 Pro BTC (motherboard designed specifically for GPU mining).
  • Other slight component changes to get the best prices for components.
This is now a 2,700 Kh/s 6 GPU mining rig that will cost only $1.8k USD to build at current prices.

aleksandrd, I stay on the conservative side when quoting expected returns, especially since most people don't understand the way price drives difficulty. With a large jump in Litecoin value, more people start mining which pushes the difficulty up faster than usual. So, while a calculator may show you making $1,800 in one month, this will most likely not happen due to higher than normal jumps in mining difficulty.

I've updated the 6x mining rig guide adding the R9 280x as the best alternative to the sold-out 7950 GPU.

Litecoin mining / Re: [Guide] 6 GPU Litecoin Mining Rig | 6x 7950's

Zedicus, thanks for clarifying your question. There are no Litecoin ASICs in development at this time. Scrypt based currencies are designed to be much more ASIC resistant than SHA-256 currencies (Bitcoin). There are FPGAs in development, but even those won't provide the advantage enjoyed by Bitcoin miners who bought FPGAs last year. I would be very surprised if either of these technologies evolved to a sufficient level to push GPU miners out of the market in the next 12-18 months. Beyond that time frame, no one really knows. Hope this helps.

Litecoin mining / Re: [Guide] 6 GPU Litecoin Mining Rig | 6x 7950's

Yes. 7950s are still the best. As far as whether now is a good time to mine, that's a decision you'll have to make. To help you determine this, I'd recommend using a litecoin calculator like this: https://www.litecoinpool.org/calc. Personally, I'm very happy with the $125/mo worth of Litecoin each of my 7950s have generated over the last few months, but there are no fixed price guarantees when it comes to mining. If I had $2200 and was just getting started, I'd probably build a 4 GPU rig using the guide at http://www.coinminingrigs.com and buy some BTC on Coinbase to diversify my investment. Buy BTC and mine LTC.

Newbies / Re: Trouble getting my CPU to mine
« on: November 22, 2013, 04:36:41 PM »
Litecoin CPU mining is no longer profitable. If you have an AMD GPU in a desktop computer you can mine with that. However, most folks build a custom desktop rig (with an open case design) to keep the graphics cards cool for mining. Check out the guides for more information here: http://www.coinminingrigs.com


I'd also recommend using this calculator to determine how profitable mining will be for you: [size=78%]http://www.litecoinminingcalculator.com/[/size]

Updated original post to reflect current (Nov '13) capabilities of this 6 GPU rig.

Amazing post. I will take advantage on litecoin mining next year 8) 8)


Next year might not be as profitable for Litecoin mining. Fortune favors the bold.  :D

Litecoin mining / [Guide] 6 GPU Litecoin Mining Rig | 6x R9 270
« on: May 30, 2013, 03:56:20 PM »
After a few days of research over on the bitcointalk forums, I've put together a build guide for a 6 GPU mining rig capable of mining roughly 50 Litecoins each month at the current difficulty and exchange rate.

6x 7950 Litecoin Mining Rig Guide

I picked the 7950 since it has the best $ to hash rate value at the moment and also uses less power than the 7970. Going forward, getting the best watts to hash rate value will be increasingly important (unless you get free electricity)  :) 


Edit 11/21/2013: Based on today's Litecoin mining difficulty and price point, a rig like this will generate ~$600 worth of Litecoin per month (in USD).


Edit 12/27/2013: Due to unprecedented demand for the 7950 GPU, they are virtually impossible to find. I've updated the guide using the AMD R9 270 as an alternative as well as adding the new ASROCK motherboard designed specifically with GPU mining in mind. This rig is now a 2,700Kh/s rig that will cost $1,800 to build netting you over $500/mo in Litecoin at current difficulty/exchange rates.

Feel free to give feedback here or on the site, especially anything that can improve this guide for others. Thanks!

Litecoin mining / Re: Going to setup a mining rig. Need suggestions
« on: May 14, 2013, 05:25:58 PM »
It's pretty simple. The GPU needs a 16x slot (on the motherboard or on a riser cable), so you'll want to get powered riser cables with either 1x to 16x or 16x to 16x depending on which slots are available on your motherboard. I just wrote up a litecoin/bitcoin mining software guide as well that might be useful to you here.

Litecoin discussion / Re: I'd like to try litecoin mining
« on: May 14, 2013, 05:22:51 PM »
The following mining software guide will show you how to set up cgminer for either currency: http://www.coinminingrigs.com/litecoin-bitcoin-mining-software/


**edited 11/20/2013 to remove the comment about LTC and BTC being equally profitable for GPU mining. Litecoin mining is really the only profitable coin to mine at this time. If you're looking to start, be sure to check out the guides at http://www.coinminingrigs.com as well as this mining calculator: https://www.litecoinpool.org/calc

Because there are so many potential configurations, I haven't added that element of setting up a rig to my litecoin rig build guides, however I would recommend using GUI Scrypt Miner and tweaking the settings to find the best and most stable hashrate for your custom rig. A high hashrate that crashes your rig at 2am will net you fewer coins than a slightly lower hashrate that will run for weeks at a time without issue. You don't want to half to 'babysit' your rig. :)

As far as overclocking your 7970 rig, start with what others are using here, and find a combination that works for you. Don't forget to take heat into consideration. A rule of thumb is to try to keep temps under 75C. Otherwise, you risk premature failure of your video cards and a net negative return on your mining investment.

Litecoin mining / Re: only getting 285k from each 7950
« on: May 07, 2013, 03:24:00 AM »
I use GUI miner scrypt for the rigs I've built for others. It is much easier to setup for non-techincal folks, than say, a command-line miner. You can tweak the settings easily, to find your maximum stable hashrate.
