I'm having a slightly similar issue myself at the moment. I'm trying to overclock both cards in tandem using afterburner, and I've made it up to +100 core clock and +300 memory without adding voltage yet.
Now here's where things get screwy...whenever I go 10mhz higher than +100, upon opening any bench of any kind, the display instantly crashes, so I think "ok, time to start upping the voltage!". So I start by adding +5...then +10, +20, +30, etc...but no matter what I add, the display insta-crashes at any clockspeed above +100. Am I doing something wrong, or is there something I'm missing here? Power limit is 109%, and temp limit is maxed at 95 by the way...also, both cards are active and SLI is turned on. Afterburner is syncing settings between cards as well...
This is a shot of my current stable settings at +100 core, and I've got Hynix memory on both cardsEdited by hoevito - 1/12/14 at 9:45pm
