Overclocking

[72montecarlo]

I have been playing around with the FSB speed mostly to increase the speed of my cpu. i changed the multiplier from 12.5 to 13 one time and when i did i had to reset everything on the mobo to get it to come back up. Im wondering if as i raise the FSB do i need to increase the Vcore. I havent changed it at all as of yet but im wondering how it effects everything. thx praetor in advance since im sure you will reply. lol

haha! he is quite the helpful person is he not??? like a walking computer dictionary (no offense of course). anyways...if you raise the fsb far enough you will need to also raise the vcore. and not ony the vcore but also the chipset voltage. the higher the fsb the more voltage the NB needs to power it and the more the CPU needs to give you that set speed u want. also you will need good NB and CPU cooling if your wanting over 200fsb...passive cooling will usually just cover 200fsb...anything more and id definetly be looking for an active NB cooler. maybe someone can give u some good links for one.you'll have to do alot of trial and error test to figure out the approptiate voltage. and jsut cuz it boots up and loads into windows does not mean its stable. you have to run it LOAD for a good long time to make sure its stable. im sure someone else will cover anything i missed...its a bit vague explanation in alot of areas.

Yea that was kinda vague but it was helpful. anyone know what the maximum safe vcore voltage would be? possibly it is dependent on the motherboard and other stuff. just wondering

i wouldnt go past 2.0V for the NB...and i wouldnt go past 1.8V for the CPU. u better have some serious cooling if you want that much vcore. you can go up to 2.2V for the CPU most of the time..but that shortens chip life unless you have vapercooling or something...defietly a friend computer in no time if your using air. im on 1.75V for my CPU and @ 35C idle 45C load...give or take a few degrees of course.

Depends how much you raise it by.. after a certain point you need to increase the voltage to let the thing boot heehee

anything more and id definetly be looking for an active NB cooler

Bah! ASUS boards run fine without active cooling even with crazy OC.

Definitely NO higher than 1.75. I personally wouldnt go over 1.70 without thinkin twice.... course this would be different if you had a Mobile chip.

possibly it is dependent on the motherboard and other stuff. just wondering

Kind of but not that dependent. Your mobo, whilest not #1 in my books, is certainly respectable (since MSI designs itself after ASUS)

really?!? i never had an ASUS but every other board ive had to upgrade cooling if i wanted more than 220fsb cuz the heatsink would get so hot. maybe it was just he crap thermal compound it came with...

 

[Praetor]

Yeah if im not mistaken (and if i am its some ultraOld board somewhere prolly) but not a single ASUS board comes with a NB cooler. Just a massive AL heatsink. Sure the heatsink gets hot with OCing past 220 but thats the thing about AL, it can take and take and take and not lose its effectiveness and for something like the NB which doesnt push out as much heat as the CPU or something, the AL-HS does a dang nice job.

i put a copper on mine with a fan and a copper slab on my SB too...it looks a little in my opinion and with all the airflow in my case it works pretty. hopefully i an get 240+fsb soon..i havent had alot of time lately to try different BIOS. the epox i have has a HUGE aluminum heatsink on it...works pretty good too.

 

[Praetor]

Yeah thats a good point: AL NB-HS only work if they are huge .... I remember what i was going to say above: ASUS doesnt put a HSF on their NB because given the size of the HS and CFMs coming from the fan, odds are that the HS will be come a dust magnet much faster than without a fan.
