  Can you try mining a different coin type please? They have different backends so we could identify which is causing the problem this way. Are you mining BTC there?

  It's all scrypt mining (all litecoin alts, but not sure what coin since clevermining switches between coin types).
  
  Here's more debug log output, this time from scrypt on the fabulous panda pool:

  Just realized you wanted me to switch algorithms... Switched to the panda pool BTC SHA-256 and it's working fine on GPU. Getting around 300Mh with standard settings. So it looks like scrypt is the problem.

  This card seems to be a bit picky sometimes, if it's that I wonder whether specifying a few options in the miner settings panel would help - try setting work size to 256 and use the manual flag 

  -g 1

  then start over

  
  

  It's weird that RAM issue though, if you have Activity Monitor open is the memory allocated to the  MacMiner process or the bfgminer process?

  Same issues with work size256 and -g 1. RAM and CPU usage are being allocated to CVMCompiler actually, which looks like it's part of the OSX OpenGL framework?

  looks like a system bug, any updates to run, what OS version is it?

  
  

  might be worth trying this version which may be a bit buggy though:

  OS update fixed it. Weird.... thanks for all the help! Went from 10.7.4 to 10.7.5 and suddenly is working. So far all shares have been rejected. but now I can at least play with the settings and see what works best instead of having to reboot every 5 minutes because it's swapping.
