i've read the Q9450 is only going to have an 8X multiplier!!
maybe its just me or is this going to make it a crap overclocker?
am i better off with a Q6600 G0 9X multiplier?

Yes and No.

Don't know what kind of FSB wall the Q9450 will have.

It might clock just as high as a Q6600 with a higher Bus and less heat generation.

you would need a 450FSB just to hit 3.6 which is what most people are hitting on Q6600 running 400FSB X9

Except the problem is that the Q9450 has 1333 FSB at 2.66 ghz. That means to overclock to 3.2 ghz you need to raise the FSB to 1600. 1600 is already pretty high for a lot of the motherboards... OCing to 3.6 ghz would probably be out of the question for most motherboards because that would require 1800 FSB.

Really? I had no idea. :kaola:

Seriously though on air the limit is about 3.6 for a Q6600. The Q9450 might clock higher, who knows.

This die shrink is pretty much looking like a skip for me. Thanks be to Intel for making it a 1333 FSB.

Anyways.. I know what you are saying, it's been a debate for a while now. 500x8 is still 4.0 GHz... and the Q9450s on a good motherboard might do that.

what boards can do 500FSB stable? X48 maybe?
i know X38 can get there with a lot of tinkering!
bit of a novice overclocker because of my current mobo (totally crap overclocker)
i was gonna get Q6600 & maximus formula this side of Xmas but dont know what to do now???

I've seen some X38s and P35s getting close.

440-450 on quads. I have my fingers crossed that we'll be able to get 500 with a more mature BIOS and maybe seperate GTL Ref per die. It's been obvious for a while that the Q9450 would be limited more by it's FSB wall than thermals anyway.

well of course the X48 will. Why do you think they were designed together and coming out at relatively the same time....it's like asking if the phenom will work on a 790FX board.

So, back to my original question,
is it worth waiting for Q9450 or just buy Q6600 & ASUS MF now?
(shame intel didnt make Q9450 9X multi, that would be one hell of a CPU!)

Honestly I would just pick up a Q6600 and P5K-E now.. or wait til the Q9450 comes out and if they drop prices on the Q6600.

i wasnt asking if they will work together! i was asking if the X48 will hit 500FSB no problems

To hit 500 MHz FSB on any of these I think it's going to take some adjustment of CPU PLL, CPU VTT, NB Voltage, as well as GTL Refs.

thats what i thought! im not too clued up on "CPU PLL, CPU VTT, NB Voltage, GTL Refs"
so the thought of an idiot proof overclock to at least 3.2-3.4ghz sounds ideal to me
thanks for info :D

can anyone clarify,
whats the difference between a CPU that is 1333mhz FSB (Q9450)
& a CPU that can RUN 1333mhz no problem (Q6600)?
