Hey, I was wondering if I buy the processor Q9550, is it possible to overclock it to 3.0GHz using Asus P5W DH Deluxe?

Yes why not? P5W DH is a good board,just read the 2 guides here and u may even achive higher:

You should be able to overclock a Q9550 to higher than 3.0ghz if you want. It is capable of reaching as high as 3.6ghz (9x400) without too much trouble. Be sure to get a better heatsink than the stock Intel one if you do any overclocking, however.

Edit: my mistake, as Computronix pointed out, the Q9559 has a 8.5 multiplier, which with a 400FSB would give 3.4ghz speed. A 3.6ghz speed would require a 423 FSB

Alright, cool thanks its not that I don't know how to overclock even though I am still a noob at it . It was just I wanted to make sure before I buy the processor that I could overclock it. I mean why spend 1500 dollars when you can put some afford and overclock your way to that . Someone might say well QX9770 is like a Ferrari and Q9550 is a supra. But hey isn't that the fun driving ur fav. car beating the **** out of a big fancy car .

You may wanna think about the 9450, because it will OC to 3.6 Ghz somewhat easily.

So far the best VID out of the 45NM chips people replied with has been with a 9450.

So it depends on what you wanna end up with as a final speed.

But why pay extra for a faster chip, if you plan on only going to 3.0!

(Don't get the q9300, its the run of the litter, half the cache and junk.)

gotrice, I'm sorry to pop your bubble, but the Q9550 has an 8.5 multiplier, and the P5W DH Deluxe, with it's 975X chipset, is a poor FSB overclocker. Most boards, even at maximum northbridge voltage, struggle to reach 420 Mhz FSB on a Dual Core, and Quad Core performance can barely reach 390 Mhz FSB.

As Lupi has suggested, you should be able to run a Q9450, but with an 8 multiplier, you might reach a stable 388 Mhz FSB at best for 3.1 Ghz, so if you want to reach a higher overclock, then you'll need to replace your motherboard. Sorry.

Yes, but if you see 8.5X353 is 3.0GHz.... and the default it comes at is 8.5X334 I think, I should be able to manage to get it to 3.0GHz with no problem and plus I don't intent to go over 3.0GHz. But if I get Q9450 and with using this motherboard if i can hit 3.0GHz I'll be happy since its like about 200 dollars cheaper. Well thats what I did with my currently E6600. I got it to 3.0GHz at 1.3v vcore. I don't know lol to me 3.0GHz is just a good spot.

Get the 9450 then, because either way, its up the the Mobo, yes? It has a x 8 Multiplier, so you'd need 375 FSB for 3.0.

From what I can tell, your Mobo can get a decent FSB, well over 400. So no problems there! Might as well go for 400 FSB anyways to get your 800 Mhz RAM runnin' in sync and at full power!

That would be 3.2 Ghz on the q9450.

--Lupi

Yeah, I think thats the best way to go for cheap. Still remember my RAM huh? lol

you would be better off with the q9450, if i remember some mobos can't support half multipliers.

I got a small question is X3350 and Q9450 same processors or something?

I think one is the Xeon brand. I think the socket is 771 or something. But fundamentally, the same chip.

--Lupi

Hell, looks like it is even the same socket!!

Product Name Xeon UP Quad-core X3350 2.66GHz Processor
Technical Information
Cache Memory 128KB L1 (Instruction) - 12MB L2 (Advanced Smart)
128KB L1 (Data)
Clock Speed 2.66GHz
Front Side Bus 1333MHz
Physical Characteristics
Form Factor 775-pin LGA Socket T

Confusing different name but same chip lol. Anyways another question does Q9450 not work with windows xp?
