is that buy running a bench test or jutst playing games or something else?
Not sure what you are asking. Sorry.
I bumped my FSB on the 1055T to 250 with a multi of x14 and left all my voltages at stock. Stable at 3.5. Since I left Turbo Core on, I get 4.1 on three cores when boosted.
I have run LinX for over two hours and Prime 95 for over four hours with the Hyper 212+ and never saw the temps rise above 43C during those. With the stock cooler, I was hitting 55C. Now the Phenom II's can get a little touchy at temps above 50C (I have heard but did not experience myself) so I changed my cooler. In games I never come close to those temps.
With the 1090TBE- All you will have to do initially is bump your multiplier for great overclock. I have seen x18-x21 in some.
