yeah i somehow think that 8 hours is a good one, but if u want to know for sure, u would probably need to go for a solid 24 hours .

79C considered ok laa .
no need to fork out thousands of dollar on WC just to get a reading of 60C .
yes it'll give u more headroom for OC but i dont think its worth it that much .
ur doing great with ur OC there .
just try to see if u could go with lower vCore .

haiyark that's like ur saying any car can drive at 100 but y buy mercedez instead ?

its because of the safety liao .

please remember than unstable overclock might be harmful to your hardware as well .

example, auto restart and such, can affect ur hardware .

i'd say a solid 8 hours is a good stress test .
but my low end rig failed after 10 hours .
now that is stressful to me T_T

possibly unstable ram .
