Overclocking Intel i7 3770 3.4Ghz (non-K version) with stock HSF - is it possible?

[Brat Gvidon]

I'm a newbie to overclocking today's technologies, but back in A64 3000+ days I was deep into overclocking, cooling, etc. and did quite well.

I recently ordered the non-K version of Intel i7 3770 3.4Ghz @ 3.9Ghz Turbo with stock cooling. I know it is not very overclockable, but it appears there are some possibilities. My motherboard is ASUS Sabertooth Z77 and RAM is 2x4Gb Corsair Vengeance 2133Mhz (2T). I inquired about overclocking in a different thread (off topic) and received the following reply:

"Actually Non-K CPU's should have a few bins over their maximum turbo mode, so you can get it to 4.3ghz. A 3770k should have up to 63x multiplier but a 3770 non-k should have 43x or 44x. As this is around the maximum overclock for Ivy Bridge on air for most people you're not actually that bad off. If you can get it going you'll gain about 400hmz over top turbo speed.

But you're using an Asus board as it'll turbo all cores to 3.9 at stock anyway, you were never really going to gain 25%, you've only really capped your overclock potential on air by maybe 200 or 300mhz."

1. I used Google and found out that using BCLK an overclock can still be made, but it will affect the whole system, including SATA and can create write/read corruption/errors. Is that true?

2. I would appreciate if someone could explain this whole thing to me and let me know how to squeeze everything out of my non-K CPU. I know Ivy Bridge CPUs run hot and I have stock cooling, so possibilities will definitely be limited.

3. Also, since I would need to set a divider to utilize 2133Mhz of my 2T RAM, would raising BCLK affect that as well?

4. Should I somehow disable Intel SpeedStep to make my CPU run at maximum speed at all times?

Thank you in advance!
