Hey ,is it possible to get instability ,but at the same time get zero artifacts along the overclock?

post #1 of 2
Thread Starter 
I was doing OC the usual 15 mhz step way[15mhz/15 minutes] ,nvidia driver restarted ,but there were no artifacts along the way beside the nvidia driver restart after I got an black screen.
Temps never went over 60*C. I have never experienced driver failure/black screen before artifacts and those I ask if it is a common thing.
Can it be that it was a psu not delivering enough power ?

Currently I got into stable OC[+100 mhz core clock] ,set a custom cooling preset[60-70*C = 60-100% ;45-60 = 30-60% ;27-45 = 30%] [panic;load;idle].

In general the OC of core clocks works in a very strange way on my machine by default there are 3 gpu states[previouslly I couldn't overclock at all ,after some kind of msi afterburner update I can]:
1.low power one
2.beetween the two
3.stock max clocks
When I oc there starts to be a 4th one showing up?:
1.idle
2.beetween the two
3.stock clocks activates on game menus/non-demanding 3D
4.overclock activates on demanding 3D games.
Also the oc steps aren't the exact 1:1 of what I set ,it seems like there is some kind of preset oc/boost clock speeds(the memory clock speeds oc normally ,but they don't like oc at all so I left the be) ,the thing is gtx 650 doesn't have nvidia gpu boost.
