    Hello ....
    i have changed my bios last night but i couldnt get up my system with my last Option !
    it doesnt come up and doesnt Beep too ... it causes from CPU . cuz rams OC'ed Ok and working well ....
    but CPU cant get up ... i decreased/increased NB Voltage but it didnt do anything ! :(

    Roll back the bios. Some bios versions are just not good for overclocking. Happened to me with my memory, can't overclock it (or even run at stock) after a bios update.

    thanks for advise but this bios is more stabel than before ... cuz in old bios when i had to reset the system manually i couldnt got my system up whit OC option ! so i had to Run at stock and come in windows and then reset it by win and OC then come back in win ! its tough .. u know ...
    cuz of this i cant Roll back ..
    any other advise ?

    Might be an FSB hole.

    My mobo is a p5k-vm and it doesn't like going over 350fsb (but this is due to my chip only being 800fsb)
    The q6600 is a 1066 chip right? Try lowering it to 350x9, then raising it past 410. in general your motherboard should be able to handle around 450fsb.
    Also, down-clock your ram back to 800 just to be sure it ins't that

    drop the memory to 800, since the FSB is 400 if the memory is at 800 itl be 1:1 ratio
    assuming your strap is at 400 along with the frequency

    the new bios has lowered voltages. thats why its "less stable with overclocks" if u want go back to your old bios, the thing is the reason that the old one was failing to cold boot [mone does this too!!!] is because your cpu is booting at the default multiplier, and your droping its multiplier, and your only giving it voltage for its multiplier you have it set at, so its stable but only after the multiplier drops, this is an artifact of bios adjustable multipliers and stuff instid of jumpers. you definatly get much better performance with the memory at 1:1 ratio so its worth it for some people to resave bios on cold boot.

    200 = 800, 266 = 1066, 333 = 1333, 400 = 1600, 533 = 2132 and at 1:1 ratio will net you 1066mhz memory, and dont expect anything to do it except a good p35 with a fan on it

    p35 is QDR

    i tried in 800 Too ! but it doesnt come up !
    these latest posts mean that i cant OC my ram and cpu together ?
    266 is default i think ! so what can i do ?

    i just said what to do :) set your FSB strap to 400mhz, then set the FSB to 400mhz then go down and set the ram to 800mhz, set your cpu multiplier to 6x, set the voltage to 1.100v then save your bios, then every time you cold boot, it will complain that your overclock has failed or whatever so go into the bios then save and exit and it will successfully boot :)

    since you are only running the memory at 800mhz you will probably be able to get some really sweet timings, and since its 1:1 you will get the most out of your bandwidth too

    you wanna overclock the ram and FSB together, and have the cpu frequency be a side effect of that.

    Hello ... happy new year ...
    i did everything ... i went everywhere ... but i couldnt get my pc up with this OC .. i used 266 ... every thing u might think ... but it doesnt :(
    can a normal user like me mail asus support and ask them for solution ?
    i dont know what can i do :(
    P.S : may be i did everything false ... can u change for me my old option and post it here ?
