    Overclocking E6750

    ok this is prob a v noob question. but if i just change the cpu multiplier from 8 up to 9 whilst my FSB is 333 and i keep that the same, will that be alright??? or will i have to change voltages and stuff??

    sorry for being so clueless

    thanks in advance

    Well I think it is best to start with max CPU multiplier and increase the FSB, anyway with most motherboards (esp Gigabyte) you can play and do trial and error and re boot to previous bios setup, if things go wrong.
    2nd computer gigabyte P965ds3p, 7770 E2140@2.9ghz, corsair HX520 6 years stable, replaced now with E8400@3.9ghz and will overclock more when I'm bored.

    Re: Overclocking E6750

    You're e6750 along with many others has what is called an "Upward Locked Multiplier", whereas the CPU will not let you adjust the multiplier past 8 in your case, 6850=9 6550=7 and so on, so no it is simply not possible. The Xtreme edition of Intels CPU's for instance the X6800 or QX6850 have an "Unlocked Multiplier" where you would be able to do what you listed with supported voltages.

    Re: Overclocking E6750

    so what if i change the fsb ?? can i do that a bit without increasing the voltages, also does anyone know of a graphics card tweaker that works with vista 64bit

    thanx again

    Re: Overclocking E6750

    Other than nTune, no.

    Yes you should be able to increase the FSB reasonably using the [Auto] setting for your CPU voltage, or 'VCore', but only to a point, if you are attempting anything over 1.5v you might have to start manually setting the voltages. However yes, a slight overclock to 1500Mhz FSB(QDR) or 375 which would give you 3.0Ghz should be achievable using the Auto voltage settings depending on your motherboard.

    Re: Overclocking E6750

    thanks for advice, i was just looking at clunks giude to overclocking, and then finally built up the balls to do it. when i went inot the bios there was no option to change the anything other than the multiplier so no option for FSB, i played around with a few things and still couldnt find it, any ideas? what i did find is that the motherboard i have can be set to oc itself automatically so at the moment im on a 5%overclock putting me at 2.8Ghz, im currently running everest ultimate to check temps as im on air, but still slightly annoyed i cant change it myself.

    thanks again

    it's not an msi board is it? i had one and it would clock from 1% upto about 10% and it was pants. if it's an asus board and you follow clunks guide it's easy to chabge the fsb, mine is sat on 3.3Ghz @ 425 fsb and thats in a matter of a few keystrokes.

    Re: Overclocking E6750

    thanks all for your replies, ive got an asus P5N-E SLI board, and ive read clunks guide but the problem is when i go into the bios it only comes up with the option to change the multi and obviously i cant increase it as stated earlier, and there is no option for changing the FSB. So at the moment the only way i can OC is by letting the AI do it which is an option on my bios so at the mo ive OC'd it to 5% but cant actually do it myself. does anyone know how i can get the option to change the FSB??

    cheers again,

    Re: Overclocking E6750

    Couple of screenies in this review of the P5N-E SLI that might help - does that look like your bios?

    The review states that the bios the board ships with is 'limiting' so perhaps you are going to need to update it.

    Have you set AI tuning to Manual? (In the BIOS)

    Re: Overclocking E6750

    yes that is exactly what my bios looks like. i did try to update it but i couldnt find anyway that updated it for free, you had to pay. is there anywhere that doesnt?

    Also yes i have set the AI tuning to manual but it still doesnt work.

    i am semi annoyed,

    thanks as always,

    Re: Overclocking E6750

    This is the spot where you raise your FSB, simply set to Unlinked ad set your FSB as desired.

    Hmmm.. Paying to update your BIOS? thats new.. You were obviously looking in the wrong place, simply go Here @ asus.com/support and enter in your model number and such to download the latest BIOS, be careful if done wrong can render your motherboard useless.

    Re: Overclocking E6750

    alright then, as im completely new to overclocking, what sort of FSB should i be looking for on a slight overclock (not too slight). also i have found the bios updates for my motherboard, how will i know which is the right one, isnt getting the latest alright??

    Re: Overclocking E6750

    Normally the one that is available for download is the latest BIOS release from Asus.com. I would not recommend using Asus Update, it killed my old P5B...

    Anyways... There is no magic number for overclocking, read guides, educate yourself before you start fiddling with things that could possibly break your computer.

    Here is a ratio to get you started... (375*8=3000Mhz[3.0Ghz]) (375*4=1500 QDR FSB)

    Numbers in red are FSB speeds
    Numbers in blue is your multiplier

    Okay so lets say you wanted to overclock to 3.2Gz, you would need to set your ratio to Unlinked than set the FSB to 400. (400*8=3200Mhz [3.2Ghz])

    Or lets say you wanted to overclock to 3.0Ghz.. (3000/8 = 375 FSB.

    It's all about ratios, you just have to get used to it, take the speed you want.. 3.5Ghz = 3500Mhz.. so 3500 divided by 8 (your multiplier) = 437.5Mhz FSB

    IMO you shouldn't have to do anything else other than adjust the FSB as I described for an overclock of 3.0~3.2Ghz anything higher you might have to start manually setting the VCore voltage.

    If this hasn't helped, and your still lost than keep reading overclocking guides so you know what things are and what they do before you attempt anything.
