Q8400 Oc passed 3.2ghz

[venjhammet]

Hi everyone I'm new here and when it comes to overclocking I'm a newbie. I was wondering if any of you guys ever Oc a Q8400 passed 3.2ghz? I would like to know and maybe share some thought on how you did it and made it stable? I know Q8400 is not that great cpu but I would appreciate if someone would teach me how to tweak passed the 3.2 mark.

hi new guy and welcome to occ! ...the q8400 isn't known as a good overclocking chip because of the low multiplier and fsb limitations. you'd be good getting that to go much over 3.2 ghz... q8400

you'd have to raise the fsb to 400 in bios and i don't advise that unless you have a good cpu cooler attached first...mostly you'd be better off with a better chip...

I disagree

 

My Q9450 has the same multi as the Q8400, just get a nice p35 or p45 and you wont have any FSB limits.

 

Of course an aftermarket cooler is necessary (and judging by the processor choice, I'd say this is a tight budget system so get a Coolermaster Hyper 212+ or Sunbeam Core Contact Freezer 120, whichever is cheaper)

Thanks for the reply. Actually I had it already Oc to 3.2ghz. Yes I am using a Deep Cool Ice Edge 400Ni as my cpu cooler. Prime95 full load temp is just under 51 degress Celsius at ambient 30 degress celcius. Core voltage is in auto and it doesn't even go near 1.2v. I have a good motherboard that is Asus P5Q SE Plus, it's a good overclocker board. I was just curious if anyone had it more than 3.2ghz and what were the proper adjustment needed to get it stable. I haven't tried adjusting the fsb more than 400 cause if things go wrong I pretty much don't know what to do.

Proper adjustment needed to ge it stable may vary depending on mb/chipset, ram and cpu itself.

A freind of mine push his q8400 to 3.6GHz (450x8) on EP45-UD3P but I don't know how much voltage (vcore, vtt/fsb, nb/mch) had to be added.

Usually it is trial and error thing. I suggest read this guide: http://forums.overcl...showtopic=71656 It was very helpful when I was OCing my pc.

4ghz is doable with proper motherboard and cooling, I've been well past 500mhz on air cooled p35 chipsets in the past, with an 8x multi and 45nm it shouldn't be hard if ya know what your doing

 

3.6-3.8 shouldnt be a big problem unless the current mobo/hardware cant handle it

i'm not sayin it won't go there ivi, just that it'll be a pita to get it/keep it there for not that much improvement...3.2, 3.6, whatever ...if it's just for the fun of it then ok fine...i loved seeing verran's and graysky's guides again qu4k3r, thanx for that...!

THis article suggests that you can reach good overclocks with this CPU without a massive amount of volts. I think your limitations are possibly your mobo or Ram.

I had a q8300 that i was able to get 3.6 ghz stable at 1.45v. its def doable but like people have mentioned you need a good board, ram, and good cooling to achieve it

They used a TRUE120 cooler.-

Good cooling, specially for applying 1.45v to an 45nm for 24/7.-

 

I had an E7200 (on the same rig I have now) which at 1.3625v didn't pass over 3.3GHz no matter how much FSB and/or MCH volatge I added.

I mean sometimes OCing is a lottery.-

Wow at 4.0ghz, that's something. Love to crank up that high but I do have my limits, I mean pc parts here ain't that cheap even for a low end cpu. Maybe I'm good at 3.2ghz for now. I'll be upgrading to Corei7 in 3 months from now just saving up all the money i can. Thank you everybody for the good advices.
