Are These OC Settings Good?

Today I wanted to raise my CPU overclock a bit to see if I could push further. Are my settings alright? My i5 3570 reaches 4.3Ghz on single thread loads, I bumped it up to 4.2Ghz on all threads - I'd try and get to 4.5Ghz but I was having problems getting it remotely stable at 4.4Ghz with good temps. It was sitting at (-100mhz - 4.1Ghz all threads) for around a month now and I'm trying to push it more.

Any ideas on how I could raise the overclock any further? I can't seem to get it stable at 4.4Ghz but want to reach it if possible (and if possible aim for 4.5Ghz).

I guess raising the BCLK could be an option but I thought anything more than 103 isn't a very good idea.
