What does it mean when system reboots by itself?

Hi, ok, Im new to overclocking. My computer specs are below. I recently was doing;

18x148fsb
ratio 1:1
timings 2.3.3.6.10
vcore on auto at 1.50
vdimm at 2.7

and everything seems to run very good and definitely faster even though it was only a 260mhz increase from stock. But whenever I would run maxload cpu for a while the system would just automatically reboot. That's when I set it down to 18x146 and everything seemed good, but it happened again today. What do I need to do to prevent this from happening? How should I adjust my settings, any ideas? Are my timings off, or should I up my vcore? Change my ratio maybe? Or is my hardware just not able to support the overclock? thanks :D
 
Whenever you overclock, you have to test for stability. Most people use Prime95 (google it) for several hours (usually at least 24 hours straight) to test to see if it's stable. If it's locking up, then it's not stable. It probably needs more voltage. Ratios are fine, your ram can handel it.

I'd up the voltage a notch, then run Prime95 for a while and see if it's stable. Also, keep an eye on temps, as whenever you raise your voltage core the temps also go up.

Good luck! :)
 
thanks, cool yeah, i'll have to run that program. so you think it could be my vcore then? i've tried upping it and it only seems to make things more unstable. sometimes windows won't even load when i change the vcore. hmmm.
 
In most cases of instability it's voltage. i would do what above said guy pointed out. If windows won't boot, then it could be the board, and you might to check out another one.
 
9 times out of 10 if you don't have a major IRQ conflict this points to a faulty or overloaded powersupply
 
Some already excellent advice given here. I once had the same problem and tried all of the previously given excellent remedies here with no success. The last thing I checked for and found to be the source of my reboot problem was a dying CMOS battery. If your system is two to three years old pop out the battery and check it's voltage with a DMM, and replace if necessary.
