Hi everyone. I want to know why overclocking a GTX 1070 doesn't work. So I have an AMD FX 9370 and an assrock 990fx extreme9 mobo. I have downloaded MSI Afterburner and I put the the clock speed and the boost clock up a little and my system crashed. Why? I have asked you before and you told me that if I overclock my GTX 1070 my system won't crash. Why this happens?
P.S. I have an 1080p 60hz monitor.

I would say it was power related ProPlayer.

With anything you over clock on your system it will always require more power from the Psu to keep it stable.
It depends on what power supply you have, and how many watts and amps it can provide.

If your Psu is the bare minimum recommended to run the graphics card on your system, with all of the other components of it requiring power from the power supply at the same time you may of just tipped over the maximum power output you Psu fitted to your system can provide simply by trying to overclock the graphics card ProPlayer.

In such a case it will trigger a protection circuit of your power supply, such as Over current protection.
Where the Psu will either shut down the whole system or reset...

Well thanks for the information. The truth is that I have an Corsair 650VS power supply.
My PC specs:
CPU: AMD FX 9370
GPU: INVIDIA ASUS GEFORCE GTX 1070 FOUNDERS EDITION
MOTHERBOARD: ASSROCK 990FX EXTREME9
PSU: CORSAIR 650VS
CPU COOLER: CORSAIR H100I
RAM: CORSAIR VENGEANCE PRO 16GB 2x8GB
HARD DRIVE: SSD 240GB
CASE: CIT APACHE GAMING CASE-GREEN
So my questions:
1. I think that my power supply is good for my system so why my system crashes when I try to overclock my GTX 1070?
2. To overclock my GPU what do I have to do?( I think that I have to get up the clock speed and the boost clock but I'm not sure. It may be that I get up the wrong thing to overclock my GPU and my system crashes).
P.S. I use MSI Afterburner to overclock my GTX 1070. Thanks for the help.
