Wow!!! 4c81? Totally curious!!!
Anything soldered?
Where did you found those values?
What sort of black magic did you cast on these things to get it up that high? I can barely run one of them at x0981 (2 GHS) with 0 HW errors and the other at x0881 because if I bump the lower one up, I get mad HW errors, and if I bump the other one up to x0A81, I get about a shit ton of hardware errors...
Definetely not stock - I changed the resistors to 10kOhm & 3,9kOhm and stuck some heatsinks into it.
Only one Ant in use at the moment, but ordered second one just yesterday - plan to do the same mod...
