OK so when looking for that sweet spot in mhz (Newpac) how do you tell you have found it. I have adjusted from 100 to 200 and only difference I see is gain in hashing. So how do you know you have reached that tipping point where you will gain nothing more or are loosing some other part of function?
If your hub is strong enough you can go upto 600m. VH's latest itteration of cgminer has the auto tune function so it will automatically find the best freq to run the sticks at. Anything over 100m though and you needa fan blowing on them.
