Is my 765m a bad overclocker??

I've own my AW14 for a year now and it has been a great experience. The only problem is that gpu overclocking seems to be very unstable these days. I'm not even talking about extreme overclocking here but just pulling the slider in msi afterburner. the 901MHz stock boost clock is rock solid and no issue whatsoever. But when I want to sqeeze maybe a bit more performance and turn it to about 1 GHz (around +115), there is some screen tearing happening. After a few minutes of gaming, the gpu seems crashed: screen goes off, and on again with clockspeed back to default

This happens as well in any vram overclocking. I've never successfully overclocked the vram to a significant level.
I am running on a freshly installed windows 7 on an ssd, with A09 bios.
Whenever I game, I have rivatuner running to monitor temp. etc. It is not a thermal issue as far as I can tell. I have the cpu running below 80 C and gpu below 65 C at any moment.
I suspect it's a power issue. Either the worn out battery is not providing enough power to the machine or the AC power brick is not functioning well. Is there anyway to check this?
Or my gpu is just simply a bad chip after all. Any thought guys?

 

Some chips overclock highrt, some lower some dont like it at all without extra juice in form of more volts.

It seems you were not that lucky.

 

GPU overcloking is not officially supported by us, it may cause issues like the one you describe due to power limitations and hardware limitations. If anything happens to the machine due to this it will not be covered by the warranty.
IMHO the issue may be that the GPU is not being able to retrieve enough power from the PSU.

 

I think I'm going to give up the idea of overclocking.....
not because I'm worry about frying up my machine, but just now I tried to overclock the gpu together with undervolting of the cpu
it didn't work out and my computer shut down in mid time of me playing fable 3
when I boot it up again, that stupid microsoft live says my save is corrupted. really?..
My near end game save is gone forever.....
I HATE microsoft live so much

anyway, thank you guys for your replies

 

I hope you didn't lose your save game for good. Overclocking is a learned skill. You can't just crank up the slider and let it rip and expect good results. It's always good to test your overclocks before trying to game on them. Running some in game benchmarks or 3DMark is a good way to stress test your overclocks without interfering with your regular gaming session.

 

It's gone forever...
I am sure my game wasn't being saved when it crashed but the save is "corrupted" for no reason
I presume it's some "anti-piracy" or "anti-cheat" bullcrap that not allowing sudden closing of game
Thanks for nothing microsoft, all you did is made me sign in to a pointless account to just play the freakin game and screwed up my save

by the way, I think I'm really unlucky that my machine has zero overclocking capability. I ran 3Dmark before and it struggled to even finish running it with overclocking
