Just got a "new r-box" or r-box 100. Have it running on BFGminer 5.0.0 and unable to clock it up to even default speed. Is there a different driver I should be using?

 Before I purchased it I saw on the site that it claimed both cg and bfgminers supported it... anyway I'm unable to set clock speed higher than 290 --site says 340 in both miners-- when I try; I get this message: dangerous clock speed
 Anyone know if there's a simple way to get this thing mining at it's default speeds or am I stuck with only 47 effective GH of 100?
