I'm getting 4% HW errors using the 387.5 freq settings and only getting 189.7 Gh/s. I tried both 400 settings (0780/35 and 4f81/36) and I was getting 15% HW errors. My temperatures are always below 50.
Is 4% HW error acceptable or is overclocking not really viable for my unit?
4% is high. Anything over 1% and my impression is you are just wasting energy.
My S1 gives a .44% error at 387.5 which is higher than I would like but appears to be acceptable to the community.
Mine are below 50 as well with ambient room temps.
