Nice video.  Thanks for taking the time to do it.

Thank you very much!

[mstrongbow]

Thanks all! I am not big into making videos these days but I felt this was a much needed guide with the recent difficulty increases.
Apologies for the low quality, I don't have a good recording studio setup and I am only using a GoPro Hero3 and I think my SD card needs an upgrade or something...not sure why I cannot upload a higher quality to YouTube but it works.

Kind of wish I had seen this before I sold 10 of them last month.  Those things can sure suck power.  Had to get an electrician install a new line into my garage.
I've since moved my gear to my workplace's basement.  They pay less for electricity anyway.

I am putting all  the links on my  thread.

   Edit  I put them on my thread.

 

  with the new issue on the s-3 and it's failure to run at high overclocks.

   this info may help to find the best speed for the s-3 along with  the continued use of the s-1

BUMP!

Uploading a replacement video now and will post the new link asap!
