How to change Rockminer R BOX Frequency and increase hashrate ?

  Are you using the cgminer window or the ASIC/bfgminer window? if cg the flags should look like this I think

  
  

  --rock-freq 330
  

  
  

  with 330 a commonly mentioned frequency

  
  

  didn't find any clock setting for r-box in bfgminer in my quick search though

  I am using the FPGA/ASIC window. So do I put the --rock-freq 330 on the FPGA/ASIC window ?

  in the FPGA/ASIC window it's using bfgminer - the info is sparse and bitcointalk.org seems to be down but at least for the 30gh devices you would use the flag (in MacMiner options panel for the FPGA/ASIC window)

  
  

  --set rockminer:clock=330

  
  

  Keep in mind that increasing your clock while potentially increasing hash rate also increases heat output power consumption per GH (decreasing efficiency) so if your profitability is affected by power costs you might actually be better off UNDER clocking the device which would also lower the chance of component failures.

  I also have another question, I already put in the --set rockminer:clock=330 but when I put it in the manual flags, the FPGA/ASIC window goes blank and stops working, so I'm assuming I also have to put the -S rockminer:all   in order for it to detect the rockminer right? but How do I put both at the same time without erasing one or the other ?

  now that I've done that, macminer seems to restart and my hashrate is super low like at 8 ghs I don't know what I did wrong

   -S rockminer:all  --set rockminer:clock=330

  
  

  that should do it - with the speed problem the clock must be either too high or too low. Try 320 which should be default and see how it works, just to make sure the clock setting isn't failing to work due to being designed for the last generation rbox

  Actually it looks as though the bfgminer command for the 100GH units is 
  

  
  

  -S rkm:all --set rkm:clock=290
  

  
  

  decrease the clock to 250 to see whether pushing it to 330 is causing it to fail, and lower average hash rate, then step it up in increments

  
  

  But if you want to get the full speed out of the box it looks as though you'll need to use the cgminer window

  
  

  To test that out enter this command in Terminal

  sudo kextunload -b com.silabs.driver.CP210xVCPDriver64
  

  
  

  Then start the CGMiner window

  If you have other USB miners that depend on this driver they should be switched to that window too as CG requires these drivers not to be installed to work while bfgminer requires them to see the devices.

  
  

  If that works well you should uninstall the silabs driver.
