Energy saver phase 3 ended this morning on my Titan with 1.0.2 firmware of GenTarkin, so I click "yes" to apply settings and to stop auto tuning process.
Here are my results (ASIC5 has 1 dead die and I set 3 dies to 325 MHz, all others are set to 300 MHz) :
Web interface says :
1240W / 1349W wall -> 1174W / 1278W wall
ASIC2 : 321W -> 304W
ASIC3 : 328W -> 310W
ASIC5 : 267W -> 256W
ASIC6 : 322W -> 303W
Before energy saver, my APC switch said 5,6 A, now it shows : 5,2 A @240V. So ~96 W down with same hashrate (~307 Mh/s avg), same error rate and rejects.
Big thanks GenTarkin, awesome work

Happy mining !
