cyberderf Posted December 8, 2010 Share Posted December 8, 2010 Trying to choose between Q9300 and Q9450. Q9300 is cheaper and still easy to overclock to Q9450 speed. I heard Q9300 have problems with OSX86. Is that still true ? Any particular issue with these 45nm CPU ?

I heard Q9300 have problems with OSX86. Is that still true ? Any particular issue with these 45nm CPU ? No particular issues with 45 nm CPUs. In fact, they're in most cases a significant improvement, although any processor with less than a 1067 MHz FSB doesn't over-clock well, if at all. Reasonable over-clocked speeds are (1333 / 1067 ) * processor speed rating for 1067 MHz FSB processors. Reasonable over-clocked speeds are (1600 / 1333 ) * processor speed rating for 1333 MHz FSB processors.

LoLL Posted December 8, 2010 Share Posted December 8, 2010 Using Q9300 w/o problem under 10.5 and 10.6. Speedstep is running well, even with overclocking (3Ghz with FSB @ 400Mhz). Good choice !

mitch_de Posted December 10, 2010 Share Posted December 10, 2010 Using Q9300 w/o problem under 10.5 and 10.6.Speedstep is running well, even with overclocking (3Ghz with FSB @ 400Mhz). Good choice ! Thanks ! What RAM do you use ? I have DDR2-1066 . Can i use that later on, or do i need other ram to (beside Q9300). I run FSB 333 OCed from 266 MHZ , RAM no OCed with Oldi E7400 C2D.
