Here is a super quick introduction to getting started mining CandyCoins. Using a Windows computer with a modern video card, you can likely get in on the CandyCoin mining action with what you have under your desk right now!
Note that this isn’t a comprehensive guide, nor is it meant to be any authoritative information source – it’s simply a quick and dirty guide to getting started for anyone who hasn’t yet done any mining. Also, note that if you currently do not have the necessary hardware (eg a high end video card), DO NOT purchase an expensive video card simply for mining! If you want to invest any money in mining equipment, modern ASIC based miners are much faster, cheaper and provide many times the hash rate per watt than GPU mining can.
An example configuration:
cgminer.exe -o stratum+tcp://mining.candyco.in:3333 -u myusername.1 -p mypassword -I 15 --scrypt --gpu-fan 100
Note that there’s a lot of tuning that can be done to squeeze more performance out of the GPU, these additional options have been intentionally omitted – there are lots of guides on the net on tuning, and with some patience and effort, you can squeeze every last hash/sec out of your hardware.
But at the very least, you’ll need to play with the -I (intensity) setting. This maxes out at 20, but you may not be able to run your card that fast, at least not without additional cooling. At any rate, start low and work your way up and see how high you’re able to go before you experience issues. You may also be able to get away with using –auto-fan in lieu of –gpu-fan, but you’re almost always safer with this setting.
It’s also advisable to enable some of the built-in safety measures, for example, options such as these:
--temp-target 70 --temp-overheat 75 --auto-fan
For more information, consult the README file included with the miner software of your choice.
Also, if you find you’re not getting expected performance out of your AMD card, try adding this line to the beginning of your batch file:
setx GPU_MAX_ALLOC_PERCENT 100
However, when your card is running this way it will be unusable for any desktop operations so don’t expect to be mining in the background and have Windows fully usable.
In closing, it is important to mention that using a video card to mine is not the cheapest or most cost-effective way to mine. When mining, video cards generate a lot of heat, consume a lot of power, and are very loud. Not to mention that running a video card flat out 24/7 will invariably shorten it’s lifespan. On the other hand, if you want a simple option for mining without the hassle, eBay is full of folks selling their mining services at rock bottom prices!
