I am probably going to buy an AMD Phenom II X6 1055T. I want to overclock it at-least to the X6 1100T BE's stock frequency i.e. 3.3GHz. But I want to retain Turbo-core. What is the max I can overclock it to while retaining Turbo-Core?
Thanks in advance.
I think you are good to go.
It will do the high-end but the volts might get ugly, so I suspect most folks would recommend disabling Turbo and running all cores 14x240MHz or so (and up depending upon your motherboard & RAMs) if you are planning on gaming - I believe the same goes for video transcoding, too.
The thinking is voltage control. Turbo works by adding a pstate with a voltage & multiplier bump. If you can control the bump with something like phenom msr tweaker you are good to go. Otherwise, the x6 will tend to run 1.5v on Turbo'd cores with a substantial over-clock. That's a bit beyond my comfort range.
6 cores without Turbo 14x250MHz - 3.5GHz/1.38v ain't slackin' (and you've cut back the volts substantially,) and is good bump over stock. A nice boost also comes with the bump in speed by the IMC/NB. The gain from any "Turbo'd" core begins to minimize.
I'm not sayin' you can't have a little fun ...
but 1.5v is not a long-term proposition, and I'm pretty good at getting the volts down
but it wasn't happening here. AMD introduced a new lower-capacitance gating with this stepping and less volts is advised, not more.
