so anybody have any information about underclocking and extending the sp30 lifetime in light of the giant difficulty increases?
Max voltage 0.67 (can't set it lower from the web GUI) and I'm getting 3.62Th/s and 0.58W/GH!
Once I figure out how to navigate and edit the "mg_custom_mode" file will post again about this.
I found it very amusing that our extreme slow corner 28nm ASICs outperform the competition 20nm
Can't wait for October ASICs

Why do you keep getting slow corner batches? This was a problem with the SP10 as well.
