May be of some interest to some of you looking to upgrade to the Q9450 who have the Asus P5K Premium.
Just messing about with my system today just thought i would see if this board would have done 450 fsb if I had waited for the Q9450 and it does it easily, not tried any higher for now but looks like 3.6 will be a walk in the the park:D

Looks good .. glad there are mobos which can do 450FSB so I can finally upgrade to a fresh quad and stop being CPU bottlenecked :)
 
Forgive my ignorance, but is this at stock voltages?

I'm getting the 9450 and was planning on doing the following when overclocking: stock > 3.2 > 3.6 > 3.8 > 4 (if it can handle it). Its my first time but I'm sure there will be an overclocking thread :)
 
well my QX9650 hit 3.8 on stock volts so I would assume the same for the Q9450. Not bad for a £111 motherboard. I am not sure what the max limit is but even at 470 X 8 will still be nearly 3.8 which is pretty good. I still think it has a nice bit to go because I was only putting 1.4v through the northbridge, raise that to 1.55v could be 500fsb :-)
 
I've run my P5K-Premium at 475mhz FSB with my Q6600 no problem.
Looking forward to the new Quads :D
 
Yes, dual core Eseries chips will... I can get over 560FSB from my E8400... But Quads WILL NOT DO 500FSB, well, very very few of them will anyways.
 
Right at this very moment I’m test a cheapy E8400 dual on my P5K Premium board to see where my FSB wall resides, I reached over 550FSB with a few voltage increases other than vcore and nb!

On the same BIOS my Q6600 would run stable at 500x8 with slightly higher voltages than it needed for 445*9, but it would do it!

I have no screen shots of high quad FSB runs only overall clocks, if my Q6600 is going back in anytime soon I will show my findings

This is Webbo's Q6600 running 500FSB

Yes, thats a 65nm Q6600 NOT a 45nm Q9 series. My Q6600 will do 535FSB on my board. My QX9650 WILL NOT DO OVER 470FSB whatever the settings/multi.

What im getting at here is that a QX series chip will be of a better quality than any of the multi locked Q9series chips, mine for example is from the center of the wafer 2nd row out, so not a bad chip.. and it still has a FSB wall of 470.

This dosen't mean that Q9series chips will be crap thou, imo a 3.6Ghz 45nm quad will be more than enough for everyday use.
 
Sorry to double post but here is a Q9550 cooled with LN2 with a 480FSB just to crack 4Ghz..

Clicky

And thats just a CPUz screenie so prob not very stable.

The highest clocks so far on the ES Q94 CPUs are iro 3.6Ghz on Single Stage or Good Water.
 
Oh and mr griffin, the Q9450 has an 8 multi not 9, so with 450FSB your looking at 3.6GHz not 4GHz

I know that! that's why I said 3.6 not 4.0 in my original post. I just had mine at x9 but was just showing that a 450fsb was easily Possible nothing more.
