For the purpose of this article, I’ll be using. They both provide the same ability, it’s really just whatever you prefer. Next, there’s two main ways to configure your cgminer – from the command line and from a conf file. You might want to disable them while trying to tweak your cgminer settings. Things like LogMeIn Pro, Dropbox and even Microsoft Security Essentials are notorious for dropping your hash. Some programs will keep your CPU in a high usage state and this can really affect your hash rates. If not, a quick google search should help.ĥ) You have created a mining pool account, created a worker, and have that worker username and password ready for use.įirst up, make sure cgminer has enough CPU priority that you won’t be reducing your hash rate before you even get started. If you’re using Linux, the following configuration flags may still be useful.Ĥ) You have a basic understanding of how to use and create. The following configurations assume a few things:ġ) You’ve downloaded cgminer 3.7.2 as mentioned above.Ģ) You’ve put the cgminer folder somewhere convenient for you I keep mine on my desktop.ģ) You’re using Windows (and at least Win7). Worst yet, the tweak may be a single configuration flag (or even a poorly optimized flag). The black magic of mining is your cgminer configuration it can be the difference between a 300mh/s hash rate and a 600mh/s hash rate. These credentials do not need to be secure – if someone wants to mine for you – let them! You should NEVER make these credentials the same as your main account. From this account you’ll create (at least) a worker this worker will include a username and password – usually a variation like. Regardless of the pool you choose, you’ll need to create an account. They also have multiple servers that you can add as failovers (backups for when one server goes down). Personally, I recommend using WeMineLTC because of their large hashing power, you’ll always be finding fresh blocks reducing your stales. ![]() You can see a comparison of different mining pools here. While you can mine solo, your best bet on steady income directly related to your hashing power is to join a mining pool. I’ve had no experience with HIS or VisionTek. With that said, I’d recommend the following:Īs far as brand goes, I’ve always preferred the following (in order of coler reliability and warranty/RMA replacement): Sapphire, ASUS, Gigabyte, MSI, Powercolor, XFX. Don’t overpay for hardware on EBay, your ROI will be much harder to cover as Litecoin difficulty increases. You may have luck at smaller shops like TigerDirect, or you can monitor Newegg like a hawk – they get small restocks almost daily, you just have to be lucky to get the cards you want. There’s a gold rush going on in Litecoin which makes finding hardware hard. If you’re trying to find hardware right now, you’re probably experiencing a lot sold out stock from Amazon and Newegg. HWMonitor: There’s a lot of hardware monitors out there, but I like the simplistic approach HWmonitor takes. You’ll be able to see your clock speeds, engine speeds, voltage and temperatures plus a lot more. GPU-Z: This utility will allow you to monitor everything that is giong on with your graphic cards. Some other software I recommend for your mining rig are the following: I’ve always been a proponent of ‘latest and greatest’, so I’m using cgminer 3.7.2 – the last build to support Scrypt-based mining (all cgminer versions later than 3.7.2 will not work for Litecoin/Scrypt-based coins). I’ll come out and say it: I haven’t tried a lot of the different versions of cgminer. I’ll do my best in this post to share what configurations have worked best for me using the latest AMD hardware (notably 7970, 280x and 290x). ![]() A lot of the magic in Litecoin mining is finding the best combination of hardware and cgminer configurations to get the best hashrates while remaining stable and online 24/7.
