this is what other people have been able to achieve here is the link http://www.tomshardware.co.uk/answers/id-1769927/official-msi-gtx-770-lightning-thread.html


LN2 bios + Latest WHQL drivers
Afterburner Settings:
Core Voltage: +100mV (which is the limit, unless you mod your bios)
Memory Voltage: +100mV
Aux Voltage: +50mV
Power Limit: 109% (priority)
Temp Limit: 94°C (linked to power)
Core Clock: +100MHz
Memory Clock: +400MHz
Fan Curve: 40%/0-40°C > 80%/80-100°C
*extended MSI settings
*forced stable voltage

but one more problem i have is i cant increase the Core Voltage over +12mV
