I've noticed that increasing the power target past 100 doesn't seem to run stable, and anything over on the core causes some screen tearing. This is Using Precision-X. my goal is to get this monster up at 1300 core and 1802 memory Stable, but we'll see what happens
The power target only comes into play if the card is hitting that wall. If you're at 100% and going higher is changing the behavior of the card, then you're most likely throttling based on the power target.
OC the core and memory separately. Start with the core and then after you're done move onto the memory.
Keep an eye on both core and VRM temps. HWInfo has VRM temps. You can sometimes see VRM temps on GPU-Z as well. If you're going to use HWInfo and GPU-Z I would recommend not using the 335 drivers. For some reason the 335 drivers in conjunction with something else (no one knows for sure as far as I can tell) can cause the 780 Classy to set itself to 1.5v on the core. So watch out for that.
