3770k newbie overclocking

[Bozol]

Hello guys, i'm a newbie to overclocking and finally decided to overclock my 3770k. I've read tutorials and watched videos, but i'm still uncertain about some things. So far I've found out that my CPU is stable @4.5GHz with fixed 1.19V. Now my question is - is this a good voltage for this frequency (did i get a good chip) or not really? And my problem is that it is stable at fixed 1.19V, but when I tried to use the offset mode so it doesn't put that much heat out while idling and doing lighter tasks i tried to setting it so it reaches 1.19V, but I'm encountering random instability that way. Even if i set the offset so it reaches 1.22V i get random crashes. Not BSOD mind you, just the games and stress tests randomly stop responding.

At fixed 1.19V i'm reaching 82-83 degrees under IntelBurnTest, my cooler is Noctua NH-D14. I'm overclocking on ASUS P8Z77-V with Corsair HX750i PSU, so I don't think those components are a part of the problem. I've also recently updated the BIOS to the most recent available version.

Have you checked for Load Line Calibration issues?

Well. 1.19V isn't all that much at all, so you could just let it sit there 24/7 and not care. However, if you were to delid the CPU (which is actually simple), drop your temps taht way and OC further, this might become troubling.

The instability is propably caused by the voltage ramping up slower than it has to. Do what DarkSmith sugested and see.

Thank You for the replies, i thought that voltage change speed might be the problem, didn't know what I should do with it though. I'll check it when I get home and get right back to You. Aren't my temps a bit high for these voltages and cooler or is it normal? When i was checking temps at offset mode it was reaching 75 degrees on IBT while on fixed voltage it reaches 83.

As I said, IvyBridge's heatspreader sux. It is normal to get 20°C down just from deliding and replacing TIM with a normal paste. When you delid, tap and use TIM specialy designed for die to HS, 30-35°C down is normal. Intel just fked up.
