Game freeze and computer restart

[KHansen]

When I play for an half an hour or less. The system just freeze and then it restart 10-15 sec after. There are no error mesaage or blue screen. Just freeze and restart. And it's only In games. I've got a 9900k OC to 4.8ghz and a 1080ti oc to 2063mhz. PSU 750watt.

if you lower the clocks does stability return?
does it happen at stock?

 

[KHansen]

You mean the GPU?

remove both overclock... get one stable, test it via a taxing benchmark then proceed to overclock the other.
Id start with the cpu.

The 9900k also turboes to 5,0 from what I can read here https://www.intel.com/content/www/us/en/products/processors/core/i9-processors/i9-9900k.html

So what kind of clock speed do you achieve with the turbo?

The turbo boost it around the 4.7-4.8Ghz. When I get home from work I will try remove the OC and see what happens then.
