Sorry for the misunderstanding.
What I meant was, since these parts are later weeks, and since the 1/1.2 go to 1.4, and the 1.33's go to 1.6+, then perhaps the 1.4's MAY go to 1.7+ OVERCLOCKED. Im not saying this is a new chip version AMD is secretly putting out.
The 1.33 is a 1.5 (easy O/C) "in disguise".
Nobody here really knows what the TBird AXIA or future AYIA or AZIA cores will do maximum.
You can theorize all you want, but until someone gets to cranking on one of these, you cant predict what will happen. Heat transfer is obviously the big issue here.
And BTW: All my youthful exuberance is long gone - trust me.
