    the motherboard does the OCing for the CPU, so if you take it out and put it in another board, it would automatically go back to the original specs, voltages etc.

    I wouldn't think much of anything you hear about the GTX280 until very shortly before it comes out.

    its only 9:30 over here in iowa.

    @sam, i thought that 1.35 was the safe voltage for a 45nm chip?

    I've heard many conflicting answers - so far the only safe one seems to be not to overvolt the chips at all. I think the 45nm Duals got clearance for 1.35v but not the quads.

    18 but thats beside the point :p
    what about you?

    and Quads will always need more V than their dual core buddies. esp the xenon i put. speed binned and made to stay stable under presure

    haha, oh really?

    Quad cores will indeed need more voltage - but you can't give it to them, or they'll fail within weeks. The downside of the 45nm Quads is you'll either have to settle for periodic replacement, or live with a small overclock.

    i havent heard any problems with the quads in the last month or so. looks like intel has sorted it out, and the Q9450 are typically hitting 3.6+ w.o problems now.

    its just that at the begging people were putting the 65nm voltages through them, which would over volt them too much at over 1.38

    all seems to be fine now. and they clock well, and are very cool.

    OK thank you all for your help so far. I am now at the stage of investing in my RAM. Can anyone recommend me the fastest and best 8GB of DDR2 (4x 2GB). I am going to overclock the Q9450 to about 3.2ghz per core using the Asus Rampage.

    Can someone please help me choose the best, I am not so concerned about the money but instead being able to overclock the Q9450 and having the most powerfull RAM to support my PC running a 64bit as powerfull as possible and helping FSX go as fast as possible. I use CS3 and Cubase as well.

    Many many thanks again.

    3.2 is 400 x 8 so any 8GB of PC6400 will do.

    go for either corsair or ocz or geil imo. (no fansy heasinks needed :) )

    Thanks Sam, you have been a fountain of knowledge to me! I much appreciate everything. When it comes to overclocking I am fairly new to its niche. How can I tell what is the best Ram for my board? Is it down to the brand or is there a specific speed I should be looking at. I am guessing that I should be able to overclock each core at 3.2 as someone else has managed to do that with the Q9450 but does it rely or depend on the RAM with how much I should push the overclocking?

    Thanks again.

    Thanks for the compliment... :)
    I'm a bit of a 'stick to what works' kind of guy with regard to RAM. This meaning that I always stick to recommending Corsair XMS2 stuff, typically PC2 6400 speed (800mhz) as it's rock solid reliable, and is compatible with pretty much any board out there. For higher front side bus speeds, such as when overclocking, it's a step up to using the Dominator branded PC2 8500 stuff - and exclusively this as the list of compatible memory with the good high end boards is very small at 8500 speed.

    So that would be either the link I posted earlier, or this one: http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=782925

    I confess I don't have personal experience of the 2GB modules, but have recommended them on several occasions and have had no negative feedback so far, and wasn't expecting any. For compatibility and reliability, Corsair seem leagues ahead of most other brands.
    You might say that sounds like fanboyism, and guilty as charged, but I've seen a lot of people get stung by faulty or incompatible memory. Why take the risk?

    i have the 2x1GB versions, that are 4-4-4-12, and i have relaxed them to 5-5-5-15 and taken them over 990, but havent pushed them more yet.


    brilliant sticks :)
