[asrocksux]

Hi
asrock a320m hdv r3

Cannot solve this problem 

when there is no load pc works fine
but in 3dmark bench tests freezes after 10 to 30 seconds

nothing is overclocked
bought it new from ebay germany

updated bios
updated amd chipset
latest rtx drivers

etc

is this cpu defective?

How do I hard throttle to stock 3.7 Ghz?
I need to disable auto boost right?

PSU 700 Watt

Please help
