Also you can hit mid 1400's with pretty low voltage.
I ran Valley last night @ 1502/1656 - Took about 1.42v to get her stable with no artifacts. I even had her up to around 1550Mhz.... but she started to artifact half way through the test, then driver's stopped responding. She needed around 1.45v to get there. My poor PSU was screaming " Help me" as I pushed the voltage knife deeper into the Lightning..
I might see if I can just get it there with somewhere around that voltage. I will definitely test it with my new EVGA 1300 watt psu. I'm beginning to think it may just be my psu and not my card. They really should have put hynix and samsung on all the lightnings. It has dampened my enthusiasm for getting a second for sli.
What did you put in Rbby's tool to get your voltage that high? I don't want to put in a number and have my voltage jump into the nuclear territory. I just don't think my current psu is cut out for this type of abuse though.

& compared to a Lightning with Samsung memory at 1950Mhz (7800), 300Mhz more on the cpu in this one.
Those are some awesome clocks.
When I work up the nerve, I might see if I can push mine to 1500. It's amazing the difference that the memory clock makes at least at the higher overclocks.
Were your cards giving some impressive coil whine/growl when you were pushing that kind of voltage?Edited by Bishop07764 - 2/4/14 at 5:03pm
