Help with i7 4790k @4.5Ghz or @4.6Ghz on Asus Z97 Deluxe motherboard

[mkanet]

I have an i7 4790k CPU with Noctua NH-L12 cooler and Asus Z97 Deluxe motherboard. It is currently running at 4.4Ghz using a stock XMP profile (1600MHz RAM). All settings are set to default. In Windows, the power settings are 100% minimum power state 100% maximum power state so the speed is always locked at 4.4Ghz. The temperature at ~70c-75c when CPU is at 100% utilization.

Could someone please be kind enough to tell me the minimum settings I should change to achieve 4.5Ghz (and also 4.6Ghz) without worrying about system instability and overheating with my Noctua fan?

I already upgraded the BIOS to the latest version.

I found the settings below for 4.6Ghz. however, I would like to double-check with the experts here to make sure these are the most stable settings for 4.6Ghz:

Clock Multiplier: 45, synch all cores
Cache minimum and maximum: 44
Core voltage: 1.28v
Cache voltage: 1.28v


I would also like suggested settings for 4.5Ghz:

Settings will vary from processor to processor due to slight differences in manufacturing, one processor my do 4.3 another 4.7. You need to do the testing for your chip, it's trial and error.

My OC Profiles I saved to CPUZ Apparently never saved fully.
