    Im overclocking my p4 via motherboard i set fsb from 100 to 112 gave me a reading of 1900 Mhz from 1700 what i wan't to find out is what should i set my vcore at right now its set 1.800 was 1.750
    My cpu ratio is at default 1700 My vdimm is set at default of 2.50
    Do i set any of these or leave a the default settings
    My temps rose a little 3 to 4 degee's c not to bad it's at 42c right now.Thanks to all who reply:cheers:

    Setting the Vcore would make that temp rise atleast another 3-4 degrees I would think, Im not familiar with P4s. I would suggest doing some hardcore gaming or benchmarking to test the system stability before adjusting the voltage.

    Personally, I like to use the Burn in wizard which is bundled with SiSoftware sandra(http://www.sisoftware.net/index.html...dl&langx=en&a=).

    if ur proc runs stable at ur current overclocked speed with the default voltage setting there's no need to up the vcore. If u wanna oc it higher u might need to up the voltage a little to maintian stability. Ur best off leaving the vcore as close to default as u can and still maintain stability cuz higher voltage=more heat= proc doesnt last as long :( Good luck :cheers:

    I don't trust Sandra's burn in tool anymore... I'll give ya a hint :) My 2.8ghz proc, overclocked to 3.591ghz, ran through sandra just fine... so I go play a bit of games, lock up :) Wonder what's wrong, fire back up, play again... lock up... So I'm thinking it's a problem w/ my overclocking, so I fire up my (still yet pre-alpha) game engine, and float around a map of mine and no problems... yet, as soon as i dropped the console, machine locked. So I rebooted once more, and ran my engine again with agressive settings and the puppy would start, but she wouldn't do anything. Heat isn't my issue, cpu temp was running 38 C. Sandra ran fine on a burn in that i ran for 72 hours... but as soon as i tried to do any gaming on it, boom... I bumped it down to 3.4ghz, and all was peachy.

    While sure, if there's an obvious problem, sandra is likely to pick up on it, but little instabilities i've found more often than not, it just doesn't stress.
