MSI Z87 G45 & i7 4770k can't overclock past 4.5GHz?

Hi all

(i posted this over on the MSI forums and got very little response from anyone, their forums seem kinda quiet? hence me asking here)

I recently put my cpu under water, temps are dramatically lower thanks to this... the problem is i can't seem to break the 4.5GHz barrier without putting my voltage up to to ~1.5V


I'm using Intel Extreme Tuning Utility, 60 min CPU stress test
Using the bios to apply overclocks:

Reset bios to factory, set the core voltage as below and using the multiplier to overclock


Core Voltage@ 1.4V yeilds (45x multiplier)4.5GHz stable clock @ 78c MAX

i tried 46x at 1.4V gives a bsod after ~5 mins stress
i tried 46 at 1.45V this survived a 60 min test, then i ran a 2nd 60min test which resulted in a bsod


I'd love to be able to push this up to 4.7GHz without having to put the voltage past 1.5V, i hear its possible but i guess im missing something?

Is there anyone out there with this motherboard that have achieved this? Any suggestions as to what i could try?


Thanks

your temps bro... too high for that clock speed, plain and simple. Adding volts only makes it worse.

 

*drop 10c and you wont need the extra .05vcore  ;)
