it really depends cuz i want to know how far i can go with a 800mhz and 1066 know what i mean so i will like to know wich one you recomend, stable, a for the life span of the CPU?

The main thing that would decrease CPU life is heat and voltage, if you can keep the voltage down to 1.4v(set in BIOS, not including v-droop) and the heat down in the low 50c range, you shouldn't have any noticeable decrease in CPU life. As far as memory, DDR2-800 allows you to get up to 400MHz FSB, giving you 3.2GHz on a Q9450 without overclocking the memory. DDR2-1066 gives you up to 533MHz FSB(not realistically attainable) without overclocking the memory for 4.2GHz speed on a Q9450.

Q6600@ 400MHz FSB x8 multiplier or at the very least x6 multiplier? (x6 would give you the same cpu speed while making the most of 800MHz RAM) although i realise you want a Q9450... anyone with that current Q6600 setup?
 
It really depends on how far you plan on overclocking.
With a safe and simple overclock to 3.2Ghz, DDR2 800 4-4-4-x RAM will be your best option. If you plan on overclocking further, DDR2 1066 can take you up to 4.2Ghz and still be in spec. Also keep in mind that any decent DDR2 has some overclocking head room of it's own. With relaxed timings, you should be able to push most sets past 900Mhz.

If you are not planning on overclocking and just want a faster system...
CL4 DDR2 800 will access data at nearly the same speed as C5 DDR2 1066. You will never see a difference unless you are planning on highly overclocking your system.

i cant go more than 3.2ghz, with a DDR2 800mhz?

Also i think that if i put more ram i will get a Higher Speed so you think 8gb os a bit OVERKILL?
 
DDR2 800 will get you to at least 3.2Ghz.
Any higher and you will have to overclock your RAM beyond it's specifications.
Most DDR2 800 can be pushed past 900Mhz, or 450Mhz FSB with out much trouble.
This would give you an overclock of 3.6Ghz, assuming your Mb and CPU are up to the task.

My personal thinking is that you can never have enough RAM when using a x64 OS. Load up with 8Gb and edit some video or something...

A 3.4Ghz target is a nice lazy overclock for a Q9450. Most reasonable 800Mhz DDR2 can easily do the 850Mhz. Another question is can your motherboard do the 1.7Ghz FSB required?

EDIT: I see in the reviews for the P5Q that 1.8Ghz is a easy for that board and that 2Ghz FSB may be possible.

Getting back to the original question of DDR2 800 ram and DDR2 1066, most of the 1066 ram is simply overclocked 800 ram. Take a look at the voltages and you see that 800 ram typically runs at 1.8v, while 1066 ram runs at 2.1v. So why not simply overclock the 800 ram yourself? That's what I did. Look over the reviews at Newegg and you'll find that a lot of the 1066 ram doesn't run at the rated speeds anyway. So my opinion is that high quality 800 ram should be purchased and then overclock it yourself.

Oh yes, as pcgamer12 wrote, buy 2x2 gig. That way it will run at 1T timing and allow you to go up to 8 gig later if you decide to.

Thx guys for help me out with this i have decide to buy 800mhz....so another favor i will like to you guys help me with....Which Ram you Recomend me from TIgerDirect or Amazon....i cant Order from NewEgg cuz i leave out of USA :(

The usual suspects; Corsair, Crucial, Mushkin, OCZ, Super Talent are all good. A few other companies are good as well, but I'm not personally familiar with them. One thing in common for many companies is that they will make several grades, so look for the more expensive offerings for overclocking. In other words, for example, if your see ram from Corsair that's very cheap and some other Corsair that's more expensive, it means the cheap set will work at stock speeds but may not overclock well at all, while the more expensive set will overclock with comparative ease.

^ also means the more expensive ones have much better timings eg same amount of RAM from corsair, 1 can have 5-5-5-15 timings the other will ahve 4-4-4-12 :) also the more expensive ones have better heatsinks=cooler and better overclocking...

i think the best would be getting the new P45 along with the Xigmatek cooler and any Cas4 DDR800. because most DDR800 i came accross can do about 2.1/2.2V with CAS5 at 950mhz+ and that should get you about 3.8xGhz close to 4Ghz.

unless you do heavy HD decoding 3.6Ghz+ is unnoticable in games and everyday use. i hope you see this point after OC hype.

well there is a better one i have seen from the beginning of the P45 and its the Biostar Tpower P45 people used it to broke the world record in OC and many have reported very higher OC above all the P45 and X48.

google it and you will see what i mean.
