With the release of their new ASIC, both existing and potential customers of RockMiner began asking bout their Mac OS X support…which lead my contacts at RockMiner to reach out for assistance in both verifying support and providing guidance.
The original R-Box was a ~34 Gh/s SHA2 ASIC with a familiar open-PCB design and active cooling. The New R-Box is a very sleek, fully inclosed unit that hashes out-of-the-box at 100 Gh/s.
The simplest way to get hashing at a full 100 Gh/s with the New R-Box on OS X is by using CGMiner. So, the first step is to install CGMiner on OS X. There is a thread here on the Bitcoin Talk forums that discusses several ways to install CGMiner on Mac OS X. The most full-proof method is to use Homebrew:
- Launch Terminal.app from Spotlight or your Applications folder
- Install Homebrew by entering the following in the command prompt:
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go/install)"
- Run the following command and then fix any reported issues:
- Tap the following Homebrew repository so that you can install packages from it:
brew tap nwoolls/xgminer
- Finally, install CGMiner:
brew install cgminer
CGMiner requires that no driver be loaded in order to detect the RockMiner R-Box. While this may not be a problem for many, if you have Silicon Labs CP210x drivers installed you may need to run the following command in Terminal.app:
sudo kextunload -b com.silabs.driver.CP210xVCPDriver64
With CGMiner properly installed (and the CP210x driver unloaded if needed), you can use the -n argument to list available devices with CGMiner:
[2014-10-03 16:06:37] USB all: found 21 devices - listing known devices
.USB dev 0: Bus 58 Device 2 ID: 10c4:ea60
Manufacturer: 'Silicon Labs'
Product: 'CP2102 USB to UART Bridge Controller'
[2014-10-03 16:06:37] 1 known USB devices
Once the New R-Box is detected you can start CGMiner using the -o, -u and -p arguments to begin mining:
cgminer -o hostname -u username -p password
While you can also mine with the New R-Box using BFGMiner, the RockMiner driver currently does not perform as well as CGMiner and only hits about 80 Gh/s.
bfgminer -S rkm:all --set rkm:clock=310 -o hostname -u username -p password
The New R-Box is a big improvement over the original device in both performance and looks and works great on OS X, Windows and Linux.
If you have any questions feel free to post them in the comments below or on this thread at the Bitcoin Talk forums.
And “Thank You” again to RockMiner for providing sample hardware!
