if you can't change voltage you can't overclock or underclock
1 TH is upper limit.
My AntC1 can't change voltage
Are you sure??? I've seen OC sets up with people running the chips @275mzh 0800v getting ~1.5TH/s
Can they confirm that 0800v with voltmeter?
Can anybody show foto with diffrent from standart setting voltage on AntS3 or on AntC1?
PS. For 1.5TH you need @375mzh, not @275
