what limit references should be used for overclock downvolt?
i don't understand why in my test braiins result worse than bitmain......

i've tested an s9i 13,5 on bitmain selected default hashrate with low voltage and result Gh/s 13560  W 1153 without error stable.

but with braiins Gh/s 13470 W 1170 with 1 error .... with 625 mhz and undervolt to 8.75.
