#BEST SCRYPT MINER FOR MAC MAC OS X#

ConclusionДЄnd that about covers it for my series of articles on mining Bitcoins and Litecoins using Mac OS X and Apple hardware. I verified that 3200 works well with a 57 works well with a 6870. If cgminer or bfgminer are reporting hardware errors (the HW number in the output) this indicates that you need to make use of the вЂ“thread-concurrency parameter. The last parameter I want to note is вЂ“thread-concurrency.

By removing the -d parameter so that both GPUвЂ™s are used and cranking up the -I parameter to 16 I can get my GPUвЂ™s up to around 230 Kh/s:Д¬gminer -scrypt -o host:port -u username -p password -I 16 -w 64 This gets us up to around 80 Kh/s with bfgminer as well. And with bfgminer?Д«fgminer -scrypt -o host:port -u username -p password -d 0 -no-opencl-binaries -I 13 -w 64 Now weвЂ™re cooking with Crisco! Using -I 13 -w 64 on my 5770 gets me from the original 5Kh/s up to 83Kh/s with cgminer. This parameter is what really makes a difference on my OS X rig:Д¬gminer -scrypt -o host:port -u username -p password -d 0 -I 13 -w 64 The next parameter to focus on is the -w parameter, which specifies a worksize in multiples of 64 up to 256. Similarly I get around 14Kh/s using the -I 13 parameter with bfgminer. LetвЂ™s try with bfgminer:Д«fgminer -scrypt -o host:port -u username -p password -d 0 -no-opencl-binaries -I 13 That change alone triples the Kh/s, but from 5Kh/s to 15Kh/s honestly isnвЂ™t much to brag about.

So lets try cgminer with -I 13 to see what that does:Д¬gminer -scrypt -o host:port -u username -p password -d 0 -I 13 On my system, 15-16 is about the best I can do. IвЂ™d start at around 10 and go up from there. With scrypt (LitecoinвЂ™s hashing algorithm) you need to specify a high intensity, in fact higher than is suggested for Bitcoin. This is not the case with Litecoin mining. If you arenвЂ™t using the PC, and you leave the intensity at вЂњDesktopвЂќ ( -I d), both cgminer and bfgminer will eventually reach around the same performance youвЂ™d get by specifying something like -I 9. With Bitcoin this parameter does help, but honestly not a ton. So how can we get better performance mining Litecoins on the GPU? The first parameter to focus on is the -I parameter, or the intensity.

As indicated in my previous article I use the вЂ“no-opencl-binaries to work around a crash in bfgminer with multiple GPUвЂ™s on OS X.Д«fgminer -scrypt -o host:port -u username -p password -d 0 -no-opencl-binaries Using bfgminer with the basic command-line parameters yields similar results. With no additional tuning my 5770 gets about 5Kh/s. Note that I am using the -d parameter to specify which GPU to use to simplify these examples.Д¬gminer -scrypt -o host:port -u username -p password -d 0 For instance, if I use the following command line to mine Litecoins using my ATI 5770. This isnвЂ™t really the case with using either miner to mine Litecoins. The miner will then tune itself and eventually reach a nice hash-rate. With Bitcoins you can basically run either miner and just specify your pool. Now a fair warning: finding a nice set of parameters for mining Litecoins with cgminer or bfgminer is far more finicky and time consuming. configure.ДЄrmed with a copy of cgminer or bfgminer with scrypt enabled, you can now start mining Litecoins with your GPU. If you are compiling the applications yourself, make sure to use the вЂ“enable-scrypt parameter when running. The Homebrew formulas I shared in my previous article include the configuration settings necessary to mine both Bitcoins and Litecoins. Please read my previous article on Bitcoin mining for step-by-step instructions and installation packages for cgminer and bfgminer.

In order to start using your GPU to mine Litecoins on OS X, youвЂ™ll need to first install cgminer or bfgminer. Some see it as a doomed clone, others as the next Bitcoin, poised to take off. Litecoin is not as mature as Bitcoin and is just as volatile. Whether that trade-off is worth-while is a decision you would need to make. However, if you are вЂњall inвЂќ on Litecoin then you can get a sizable performance increase by using your GPU to mine Litecoins. If youвЂ™re GPU is already mining Bitcoins, using your CPU to mine Litecoins may be an obvious choice. My previous article on Litecoin mining I discussed how you can get started mining Litecoins, an alternative to the Bitcoin crypto-currency, using your spare CPU cycles.
