4770K not stable at 4.5GHz. Help!

[twiztedhadji]

Greetings to all in the forums.

I have an i7 4770K and i'm looking to maintain a stable overclock at 4.5GHz.

Settings i've set so far:
XMP profile set 1600mhz {may be the cause but really want to keep this}
Cpu voltage set to 1.275v on air (noctua d14)
Core ratio set to 45 for all cores
Max Cache ratio set to 42
Cache voltage set to 1.20v
System agent voltage offset +0.250v
Analog and Digital I/O offset +0.195

I have the OC dialed in already and for the most part it works. I ran the realbench benchmark once without issue and stress tested it with Aida64 for about 45 mins without issue just to have the BSOD come up when powering off my PC.

The max temps at above settings are low 70's and i'm looking for help on what else may affect stability without increasing the voltage.

Additionally my board is the Maximus VI Gene and an overclocked gtx 1070.

Try changing the CPU voltage. Also a 4.5Ghz OC is high i would turn it down.

Ryan thanks for the response. I understand upping the voltage may likely help but I have specifically requested what other settings I may play around with in order not to increase the voltage.

There are many different options available for ocerclocking which I have never touched and would like to know i they may help.
