Added the --gekko-noboost setting for btc.viabtc.com and it seems to be working. no crashes so far after 20 minutes.

I set the target freq of the R606 as 600. It has run over an hour and changed the target to 368 and then 15 minutes later changed again down to 362 which result in about 460gh. I have the R606 set to 450mv (setting 6) should I move it up to 7 or down to another setting to reach stock 750gh.
