Need pro advice - 4770k related

[a66as]

After spending a week overclocking my 4770k im still having some problems. i used these settings.

Multiplier= 45x
Core Volts= 1.34V
Min Cache ratio= 42x
Max Cache ratio= 42x
Ring Voltage= 1.18V
CPU Initial input voltage = 1.8V
All c states and EIST= disabled
BCLK= Auto

In batman arkham city everything maxed out this overclock ran fine(played for an hour), max temps around 55-60 degrees C. On idle in windows its around 32 degrees C. I have noticed one RTS game i play is jittery but i dont know if its overclock related.

Another problem im having is when i switch my pc on it shuts down after 4 seconds then turns on again after which it runs fine. Also when i shut down it sometimes reboots instead. So what do you think i need to do to my overclock. Im using the asus gene z87 board. Cheers

Edit: no it isnt 3.4V its 1.34V

yes why, is that bad? reply asap before i burn my cpu

Edit: derp it was 1.34V not 3.4V, didnt get much sleep last night

Yes but sometimes it reboots instead of shutting down as well, im going to take out and re-insert my cmos chip and also reflash the bios and start again. see if that fixes the problem

batman arkham city ran really well without any jitters, it was prob just the game
