uhhmmnnn i would like to know more and learn how to overclock my cpu
i have
intel core 2 quad Q8400 @2.66ghz
i have 6gb ram
32bit OS win7 ulti
am im using geforce GT240

im new to this and i read that u can cook your comp by OC
i read some instructions (but not that reliable)
also my comp runs atleast 12-60hrs straight......

and advice or help is appreciated
please and thank you

what's your cpu temp now? check using app like coretemp or realtemp.

Tj.max 100c
core#0: 57-60c min57c max62c
core#1: 52 min 52 max 55
core#2: 56 min 54 max 58
core#3: 56 min 54 max 58

i checkd using core temp

That's high for stock clock, I take that you're using intel generic heatsink? If yes then you can forget overclocking until you get better cooler.

its been running for 2 days straight and yes my cooler sucks
awwwwwwww

You can overclock, of course. But with a rather bad cooler it would be advisable not to add CPU voltage.
So you'll probably get your chip to around 3.4 or 3.5Ghz max.
Temperatures will rise ~8% from that, still manageable.

Is that max of 62c from a stress test?
Cause some of the heavier PS2 emulation can be nearly as taxing on your processor...

3.4 will be great already for me
the 62c max is not from stress test
i got it from the normal readng of coretemp without running anythng
im tryng the load test of real temp and
the temp is rising
core#0: 68-72c min55c max 79c
core#1: 62-65 min 50 max 73
core#2: 67-71 min 53 max 78
core#3: 66-69 min 53 max 76
its running on 100% load @time 20min

my CPU voltage is at 1.1375

btw what around
temp is dangerous level?
Thank you for replyng

so i OC my comp here's the settings
FSB 435
DRAM 667mhz

C1E disabled
CPu voltage 1.1375v

everyhtng else is on default
is this setting ok?

first thing you want to check after every oc attempt = temp

oh and with that temp on stress test, you really shouldn't even think of overclocking, but it's your call.
