I am starting to get annoyed with it now, I have tried Prime and a few other stress tests but I seem to get past 20 mins and then I get a blue screen which says Whea_uncontrolloable_error. I also tried occt but it said that core 0 was getting hot so it stopped the stress test. I am currently back on default bios for time being.
I also sometimes get a A2 in corner of screen were I have to unplug HDD and disc drive for it to re boot. Also sometimes the over clocks freeze my pc up so i have to default the bios

I tried
Cpu mode-Fixed
Cpu multiplier:42
Cpu ratio-1.25 didn't boot up-1.30 was in red text-1.20 booted but bsod on stress
DramDR3 1600MHZ
Dram voltage:1.50
Ring voltage-Auto

Any suggestions ?

Thanks guys
