Title: Help with OC on bitmaintech C1 1TH/s miner
Post by: rtm125 on December 21, 2014, 05:35:05 AM
I would really like to get this thing working for its money.

I am not sure what voltages I should be using when overclocking. As always guys. Thank you so much for any help or time spent responding to this.

This is my current setup.

Miner Details - ANTMINER C1 Batch 2

PSU Details - EVGA SuperNOVA 1300 G2 80 PLUS GOLD Certified 1300W

I have replaced the front fan with a silent one and added 4 more silent fans to the miner/radiator. Now it is completely silent and colder then it was by about 5c-8c with the super loud jet fan with or without the case on.

OC settings

Default values for this are 250 clock and 0761 voltage

So currently i have 1.1TH/s +/-10% with 262.5M clock and 0.768 voltage.

The default voltage for the 64 asic chips is  0.011875 volts per chip

Currently the voltage per chips is .012, Just a number I felt like trying..

I am not sure what the ratio would be or the math equation to figure out how much voltage should be applied for what clock.

250,000,000 / 0.011875 = 0.0000000000475 voltage per 1m clock

262,000,000 x 0.0000000000475 = 0.01246875 voltage per chip at this clock

= 0.798 total voltage for this clock.

 Anyone good at math that can confirm this?

So using the above math I reduced the clock and current settings are 0.779v and 256.5m clock and getting around the same results 1.1Th/s +/- 10%
