hi guys, i am new to forum and overclocking.

I have a asus z87 a board, a i5 4670k, 1600 mhz 8 gb ram, and corsair 400r case with 2 extra fans.
After reading several topics here and some other sites, i decided i first try ai suite overclock and the reduce voltage from bios and try it.

But when i try auto tune from ai suite 3, at some point around 4.5ghz windows gives me a blue screen(whea uncorrectable error) and restarts. After restarting it says 4.5 ghz is ok. So i am asking are these values good? Or do i need to change any of them for better stability?

bclk freq: 100 mhz
ratio: 45
cache ratio : 38
cpu core voltage: adaptive and oc voltage: 1.275 volts
cpu cache voltage: adaptive and oc voltage : default (1 volts)
Dram voltage: 1.50 volts
cpu input voltage: 1.70 volts

And also ai suite says cpu load line calibration is level 8 (default was 0) and cpu current capacity is %140(default was 0) and finally cpu power phase control is set to extreme(it sayes enables and maintains active full stage phase array) (default was standart which says based on cpu phase specifications). Basically in digi+vrm tab it changed all the values so that performance is high.

So please comment and give opinions about what should i do.

edit : I run aidata's stress test and i am still running it cpu is around 80 degrees, i think this temp is a little high? what can i do to reduce it??
 
Solution
I would up the CPU Input voltage to 1.9v. Thats what gave me fits when it came to stability. Also haswell runs hot. Its because of the TIM intel used between the die and IHS

while testing aidata gave overheating error how can i decrease the temps? i dont need 4.5 ghz precisely 4.4 would work too. and cpu load line calibration and current capability being set to their max. is that ok?
