Thank you for replying, Yes i use 4 ram sticks operating in dual channel. I have noticed that i cant oc much with 4 sticks. I haven't exactly noticed what the text says in the blue screen error but it dumps till 100 and then reboots. This is only when i put load on it otherwise it will keep running.
I cant find the details on toms hardware mentioning all the voltages. There is only this (limited info)
You might want to try under clocking the ram a bit more and see if it still freezes. I don't think your problem is cpu voltage so I suspect it's the dram bus and or qpi/vtt voltage. What are you temperatures when running OCCT?
Enter the BIOS again and disable all power
saving features. These include, but are not limited
to; EIST, C1E, and all other C-states, try bclk 200 x multiplier at x 20, test it use IntelBurn Test , this isn't longtime maybe 15minutes ..
