very basic oc question

[warpigeon]

I plan to do this incremently of course, but when I oc too high what happens? Does the comp just stall when loading windows? Does it refuse to even show the post or bios screens? Do I get a black (nothing) screen?

If I oc too high and nothing will load then I have to reset the jumper on the mb , right?

I have a msi neo2 plat mb if that matters.

If it's too high, the board won't POST and you'll have to reset the CMOS and start from scratch.
If it's only unstable at a high speed, then it will crash (and reboot if it's set in the motherboard) and then you can just go back into the bios and set everything back a notch.

Well many things can happen
1. no post(black screen)
2. posts but freezes or reboots while loading windows
3. lockup/freeze in windows
4. crashes and reboots
5. blue screen error then reboot

those are some of the things. Depending on the motherboard you don't usually have to reset CMOS, it just depends and is pretty unpredictable. Normally if it blackscreens or freezes you just have to switch the power off(at the PS) for a few seconds then turn it back on and restart. If it reboots then you just enter bios and change your settings.

I have had all of these happen while overclocking my new P5B-E in the last few weeks but have yet to have to clear the CMOS. The only thing that has caused me to have to clear it was when I was installing a program and accidently knocked the powercord loose from the PS Every board and every chipset react differently, but in my experiece with quite a few the main thing that seems to require a CMOS clear is when you overclock ram too high.

What guitardaddy said is pretty much the gist of it.

If the overclock is only slightly bad then u won't even notice anything but u'll get errors if you check it with programs like ORTHOS.
