Comp freezes when overclocked

Hey guys

So if I try running at 700mhz / 1080mhz the laptop will freeze after about 30mins of BF:BC2. It starts slowing down and a few seconds later it completely freezes (looping the same sound very rapidly) and becomes unresponsive. Holding the power button to shut it down is the only way to restart.

The curious thing is that GPU-Z reports ~65*C for the GPU and CoreTemp reports ~85*C max for the CPU. Neither of these are terrible - so what gives? I haven't messed with any BIOS settings, just used MSI Afterburner (also used NVIDIA Performance tools and had the same problem).

 

With Overclocking.... it will literally VARY with every single chip produced how much it can be overclocked and stay stable...

In your case.... it's not getting enough voltage for the speed you want to run the GPU at...
You can try enabling the voltage adjustement setting in MSI Afterburner (I don't know if it works... haven't tried it)
.. Or just try lowering the clock a bit...

Is the 1080mhz the memory overclock? If it is... I would start with putting that back down to default and only overclocking the core/shader speeds....

On Nvidia cards... overclocking the memory is the quickest way to cause instability...

 

I will try that. From what I hear, o/cing the memory doesn't really make much of a difference in speed anyways.
Edit: It makes it through 3dmark06 without problems. And plays BF:BC2 fine for about an hour before acting up. I haven't had it happen in any other games, but the only really demanding game I play is BFBC2. TF2 and CS:S hardly even kick the fan into hairdryer mode. I'll try Dirt2 when I get home, maybe that will do it..
