So on my GTX 970 I have upped the core my 120 MHZ observing a boost clock of 1479mhz. MY fans are around 50 percent at 100 percent usage and the temps are 52 degrees! I have only upped the voltage by 15 MV and the power limit to 105%. I love this card, give me your results below!

Run a benchmark like heaven 4.0 for a while.It will crash or you will see artifacts if the OC is too high. Once you see no artifacts I would bring core and mem down a bit to stabilize it. I see no stability difference with voltage adjustment.
Some games are more demanding than benchmarks. I had to adjust down to +220 core +525 mem, seems to be ok now.
What's yours + voltage?
I'm currently running @ 1529mhz: +175 core, + 300 mem, 110% power, kboost on but not adding any extra voltage.
Its quite hot @ 68 C under 99% load
It's at +50mV but at full load it will run at 1250mV whether it's at +5mV or +87mV which is strange. 0mV increase will run at 1225mV which is such a small amount that it doesn't make a difference either way. Voltage increase on the MSI is iffy, but it's not really even needed. Overvoltage increases my current clock speed from 1549mhz to 1561mhz.
Don't leave Kboost on..It just runs at stock boost speed regardless of load.
How's this for a first ever GPU overclock?:

Ran through Furmark, Heaven and Valley with seemingly no crashes or artifacts. Still downloading Crysis 3 for a real-world test.
I neglected to save the last Heaven result, but I believe it came out as 59.8fps.
Observed GPU boost clock was slightly higher, sitting at around 1447.
In Furmark, through multiple runs, I've never seen it go higher than 71c. 68-69 in the others; and it's pretty darn hot in here (I've taken off all my clothes.... ahuehuehue).
As a question though, do you think I should dial back the memory a little bit?
I'm a little bit concerned as to how it lacks any kind of heatsink and also how it's being serviced by only one phase.
I've got to say... this card man. It takes anything. I can't tell you how satisfying it is to hear a little 'click' about 20 seconds after finishing one of these tests as the fans turn off.
