Well, you may have to down the multiplier or, try tweaking the offset and, try again.

Is 1.36v a high voltage for 4.8ghz?
And may I please know the safe temp is 85c or something higher?

Personally, I feel uncomfortable for temps higher than 75C for long run. Your volts is normal for 4.8ghz. As long as you keep a check on your temps, you can try to push the volts higher. However, try to keep it below 1.4V just as a safety sake. Also, always try to keep a tab on your temps. Check this thread for the max temp and volts: http://rog.asus.com/forum/showthread...re-under-water. I recommend to keep that as your max safe temp. Anything beyond, I suggest to roll back.

Something about the temps i feel very strange, it jumps up and down very rapidly. Like when it's idle, it's at 28-36c +-2c jumping every sec
and when I start prime, it reachs 78c within 10 secs, and when i stop prime, it just drops back to 38ish within 10 secs... is that normal?

Yep. That's how it works. I too am not sure why (may be the pros can ans this one!). This is the reason why, it is suggested to stress test for a longer time, so that, you are sure of the temps. That much I have learned from my experience so far!

I can easily hold it below 75@4.7Ghz only need about 1.28v so 4.7 seems to be a 24/7 stable solution?

http://www.anandtech.com/show/2468/6 This may be old however, it still gives some useful info. Read on... Regarding the above said speed, well, I too had asked this question some days back before bumping into the article in the link. As long as your temps don't max at 75C 24/7, enjoy the speed! Stress tests like prime, are more for stability check and, worst case scenario test. In real world, for me at least, the temps don't go so high. How high your temps go and, stay that high, totally depends on what you use your system for!

I still need to figure out what went worng in prime...

75'c is about where u wanna be with these ivy bridge chips 1.3v-1.35v when running stress tests like prime and linX with your cooling. Drop back down to 4.6GHz or 4.7GHz 1.3v and see if it passes. Your chip may need more voltage to get 4.8GHz stable but 80'c is too hot. if it still fails at 75'c with lower voltage and clock speed we need to see additional bios settings.

Well yeah.. so I found out the problem is more likely temp related... once I pump up my H100i fans setting to intel core nax 65c set fans to 100%
all problem solved .... need about 1.4v to get prime stable @4.8Ghz but having hard time to maintain the temp..
