problems with overclocking GTX 970M (modded/unlocked vbios)

[Emmely]

Hello, I bought a MSI GT72 6QD Dominator G a month ago, I tried to overclock my gpu and I had no problems but yesterday I installed a unlocked/modded vbios for my gtx 970m, and I overclocked my gpu core clockspeed with +400Mhz. Memory clockspeed with +500Mhz
Voltage +150mv

I tried to play games like Minecraft to see if it worked also w/shaders. I had no problems at all and the temps were about 48-64°C degrees Celsius. And when I tried a benchmark doesn't matter what one, a few seconds after when it started my screen goes black and audio still works/sometimes it stutters so I shutdown my laptop immediatly. When it started up again I tried to overclock the memory only with +500Mhz then tested Minecraft/benchmarks again and no problems, after that I only overclocked the gpu core clockspeed with +400Mhz after that tested Minecraft/benchmarks again. I had no problems with Minecraft but the same thing happened to the benchmarks.. My screen went black again and the audio started stuttering. Can someone please help me?

I just hope I didn't damage anything.

My laptop specs:
CPU: Intel i7 6700HQ 2.60hz or 2.70Ghz (I don't remember), max turbo 3.50Hz

GPU1: Intel HD 350
GPU2: Nvidia gtx 970M 3GB VRAM GDDR5

MEMORY: 16GB DDR4

stop overlocking the system!!! With a laptop you have a few variables that have to be considered (thermal envelope of laptop, limited power supply for overvolting etc)

However, the first thing is why such huge jumps with the OC. OC'ing should be done on a tested phased basis, and anyone will tell you to do the increase in small increments.

Research what your doing, or most certainly you will have trouble, and possibly kill the hardware.

Why are you trying to OC? With those components, OC'ing will not yield huge results.

Run your system on stock, and enjoy it , rather than tinker with it and potentially destroy it.
