Computer Specs : Intel Core2Duo e7400 , 4GB Corsair Dominator , Asus Maximus Formula (*latest bios) , Gainward GTX260 GS , 500GB WD , Thermaltake LCS.

My gear is running stable at stock settings, the problems start at when i change in bios the Extreme OC from AUTO to Manual , then save and exit and the computer shuttsdown then restart and all is oke .I dosent change anything only from AUTO to Manual !! .
OKe is not a very big problem but when i unplug the power cord and replug after few minutes or hours and i push the button the computer starts 1 second then turn off and restarts . But Why ? i dosent change any setting only from Auto to Manual .. ?

PSu : Thermaltake TP-600W * Tested with special Multi-Meters , all ok. ( i changed the psu with other one , same thing works only in stock setting ,

Welcome to ROG .. does this board have dual bios ??

[robert266]

BIOS
16 Mb Flash ROM DMI 2.0
AMI BIOS
PnP
WfM 2.0
SM BIOS 2.4
ACPI 2.0a
Multi-language BIOS

aa i think yes .. i read about the dual bios but mine is do this only when i change the Extreme OC to Manual . in auto mode works prefectly.

Are you talking about CPU Level Up? Or Ai Overclock Tuner? Can you specify the exact option that you're changing?

[Area 66]

Just a question, is the motherboard after restart boot in Windows ? if so it's normal when you change some setting in the BIOS to see the board shutdown and restart.

[HiVizMan]

That is quite normal and to be expected. When you change from one mode to another the bios is expecting to have some changes. And it initiates a sequence that flushes out the old settings and retrains the board. Even if nothing has changed.

[robert266]

Chino = BIos -> Extreme Overlock -> from AUTO to Manual *(nothing else )
Area66 = Yes after re-boot all starts perfectly.

but if i take off the power cord and leave it a day when i boot, warning me : Failed Overclock... , but why i dosent change anything only that .
Yes is normaly when i change a setting and it shutdown at save.But my shutting down every time when is start after replug the power cord .
If i leave the power cord in the PSU the computer start whitout any problem . If i remove the power cord sthen start again shuttsdown 1 second stay 1 second then restart . ( after restart work perfectly or Overclock Faild.

[HiVizMan]

With that motherboard and that chipset, by removing the power cord you are doing a thing called a cold boot and that reboot cycle is normal.

[robert266]

Soo all components is oke? , and this thing is normaly , and not damage anythink ?
Thank you very very much !!!

[HiVizMan]
