I replaced PSU with a 1300 watt PSU, OC'd it to 225 clock and watched the HW errors climb and pool speed fall. I turned down clocks to 200 and while HW errors are still SUPER high, it is hashing @ 1050+ on the pools. So as of yet OC'ing the S2 is LAME!
$3099 (return coupon) is NOT a good price, cloudhash price is dumping (> $4/GHS) @ $3.09 per GHS, plus power and heat I can do better letting a MEGA-DataCenter run the equipment for me.
Sorry BitMainTech the product does NOT warrant the price.
could you please post a code for overclocking? I havent seen the method laid out clearly and simply yet.
I think the voltage of the regulators is the issue, rather than power or temperature. I have a pencil and a 2000W PSU ready, and am hoping to spend some time with my device tomorrow to see how easily the regulators can all be pencil-modded. 40 resistors total that will need to be modified if you want to get the frequency any better than 225
