    Default Q8200 Upgrade Q8400

    Current MB GA-EP-45-UD3P and Q8200. Can I switch out the Q8200 to a Q8400 without a operating system reinstall and what other problems might I encounter?

    There won't be any problems at all.

    It's a bit of a pointless upgrade though. You should be able to get your Q8200 to at least 3.2GHz. I had mine stable at 3.4GHz on 1.3625V. The Q8400 is just as bad at overclocking.

    In addition to psycho's comments check out this article.

    AnandTech: The Core 2 Quad Q8400: Intel's $183 Phenom II 940 Competitor

    I can run my Q8200 at 3.5 ghz 24/7 if I wished but for 9gb/s bandwidth I need to drop it to 490 cpu /fsb(3.43Ghz).
    If the Q8400 needs a lower fsb/cpu ref to reach the same speed it could actually be a downgrade.
    ie if its just a Q8200 with a 8 multiplier but wont run any faster than the Q8200 (3.55-3.6Ghz max on air) you would have to drop the multiplier down to 7 again to get max pc performance.
    Then again I havent actually tested a Q8400 on "our" mbrd but unless its some kind of $20 swop it would seem a bit pointless.

    Zalman 10x cooler.................... Coolermaster V8............................ HP cooler
    8GB Gskill ripjaw ddr3.............. 4GB Gskill PI ddr2.......................... 4GB samsung ddr2
    60GB ssd/500GB HDD .............. WD 1TB hdd.................................... Seagate 160GB hdd
    GTX 460 1GB x2 SLI ................. Msi 9600GT 512MB(died) ........... Onboard gx
    Win7 64 ,750w psu(ocz)............ Win7 64 ,520w psu,seasonic...... Win XP pro ,400w psu

    I actually "upgraded" to a dual core. Not saying the Q8200 is a bad CPU, it's not and was fast at 3.4GHz, but for me clockspeed was important (Crossfire GPU's on the way).

    The minimum I would upgrade to from a Q8200 would be either a Q9550 (E0 stepping) or a dual core capable of 3.8GHz or more.
