This is day 2 of Dogie's Firware So far so Good Even though I had to reboot then 30 times to get the write power draw from the wall. I use A power meter at the wall and every time I reboot them I get a different power rating at startup once I get the rating I am looking for I just leave them alone I don't restart or reset JUST LEAVE IT BE!!!!

This happened with any version of the firmware But Dogie's is the best one so far as you can see no speed drops yet it stable I am not even going to touch them!!!!!

Its something with the startup surge current EFFECTING THE CLOCK CIRCUIT the Initial surge POWER from the miner is roughly between 1300 watt to 1500 watt then settles down to 790 Watt for two S3's!!!

I think this causes the Clock circuit not to oscillate improperly. meaning it locks at the wrong frequency causing massive problems with them meaning hash rate drops!!! when the initial startup surge current stays low 900 watt it stays very stable works like it should!!! the reason why I Say the wrong Frequency is this. As you go higher in hash rate the frequency goes up the more power draw it draws from the Wall in this case. Now if the base Clock does not lock in at the expected frequency it was designed for nothing will be stable it will run erratically on you example.

Power draw after miner settles after reboot with my situation.

First boot 650 watts from wall unit will drop hash rate "high start out surge current" - unstable miner speed drops

Reboot or cold start again 750 watts after settling from the wall "high start out surge current" - unstable speed drops again

Reboot or cold start again 790 watts after settling but this time the initial startup surge current was only 900 watts opposed to 1200 to 1500 watts "Miner runs stable as indicated in my PIC ABOVE!!!

sometimes I have to reboot 30 times in a row to get the settled power draw that I am looking for. I am a disabled Engineer I have to get My old lab test equipment out of my attic to test this theory but I cant I down have the schematic diagram for the S3 "in other words circuit blueprints" and I will never get them because BITMAIN and ALL COMPAINES keep them under lock and key they don't want another company or anybody for that matter building there hardware or making it better!!!

I think there Using A VCO circuit and Not A PLL circuit and don't have schematics I don't know what kind of circuit it is!!!

790W for 2 S3's at 250Freq and 1-1.2Ths/s ? What's the volts. I'm at 1050W on 3 S3's for Approx 1.2-1.3 Th/s
