I'm on liquid cooling, and on full load temps are quite low at 54°c, but if I push up the power limit over 125%, the system crash with a black screen and I must restart with an hardware reset. Seem to be related with some energy issue, because it is not the classic driver crash behavior. I red somewhere maybe due to psu spikes, is this correct? There is any way to solve? The PSU is a Cooler Master 850 Silent Pro GOLD.
Currently i'm using the skyn3t-3A-ACX-rev3a bios, and so far, i'm current stable on +440 (core clock) and +380 (memory clock), using msi after burner beta19 and should stay stable at 1.325v, though, I cannot quiete understand if my voltage read is correct: in Msi Kombustion and GPUZ i see 1.15v, but on HWInfo64 and Msi Afterburner I see stable 1.325v over full load...
Some advice please??
Your PSU is a Enhance unit with 70A, it should give you enough "juice" for those values! Only Afterburner can "see" the voltage above 1,212V (and HWinfo64 with AB beta 19 through RTSS 6.xx)
Your card is drawing approximately 440W plus your OC´ed six-core and the rest of the system you should see about 600/700W of power draw, so, in theory your PSU can handle it fine! Something is triggering the crashes or the OCP in your PSU!
If you are using the LLC hack, disable it because it can cause those crashes!
Use bluescreenviewer: http://www.nirsoft.net/utils/blue_screen_view.html
to debug your crashes and report back!

But at a certain point, 1241mhz+ to be precise, it starts artifacting when getting over 70°C.
It looks like your card screams for "water"

when i push the kboost in the EVGA PrecisionX the monitor show no DVI and screen goes black?? the same if i turn the KBoost off???? i must restart the pc then go to safe mode then again to windows
is that ok?
Use Afterburner and the volt mod to easily set the voltage directly in the voltage box!
You have the volt mod guide in my SIG!
