This is a good question. Has anyone else looked into this, and are you wasting your time OCing these units?
intriguing...
Curious also, and as i had just laying around some miners and a watt meter, i have performed a little test:
500Mhz 10.8TH 4.9Amps 1120W w/th:103
550Mhz 11.8TH 5.35Amps 1220W w/th:103
600Mhz 12.8Th 5,8Amps 1330W w/th:103
650Mhz 13.7Th 6,25Amps 1445W w/th:105
700Mhz 14.4Th 6,8Amps 1570W w/th:109
793Mhz 15Th 7,7Amps 1750W w/th:116
overclocking is NOT profitable... (on this miner...)
i also have one running 793Mhz squirting 16.2TH. Assume numbers are equal, it would do 108W/TH
best: add miners...
