my system

amd 720 x3 (no unlock 4th core)
vantec 460watt 70%eff
cooler master twin fan cpu cooler
combo drive
msi 770 c45 black color
sapphire 4670 512mb
samsung 750gb hdd



here is my problem....my monitor suddenly blank at 1st (still got gaming audio from speaker)
after a few second, the system start hang or "sot gei" with weird sound
need to restart manually


the chances of getting this problem is 1% if no overclock (2.8ghz)

5% if i overclock to 3.3ghz at 1.32v and the chances is depend on which game that i playin


i wonder which hardware cause this problem......if u said not enuff power then the symptom may not like this since i try oc to 3.5ghz at 1.4v, the system automatic straight away turn off

my cpu is not overheat since i got very good cooler system which is cooler master twin fan(hyper x212)?

anyone experience it b4? i doubt is my graphic card or mobo?

there is no need to open up new thread...use the existing AMD thread..

and also did u test for the stability? if ur OC not stable then the system will go weird..hang/freeze/auto restart/bsod and ect ect..
go to the AMD thread and read the 1st page article carefully

got... run prime95 for 1 hour at 3.3ghz no problem and amd overdrive for 1 hour no problem


the problem is the system default also lidat?1%

thats y i not sure is oc prob or not
?
