My MB keeps restarting after changing Vcore in BIOS, is that normal?

I am using 965P-DS3 and Intel E2140.

Problem is i try to OC the proc........i could OC the proc if i do not touch the Vcore.
Able to do 390Mhz.................not stable therefore i try to pump in more voltage and the things just keep restarting.
But if i wanted to set the Vcore even to the proc stock Vcore stock (default value is written "Normal"----to--->1.325V) in the bios the mobo just keep restating.

Not sure what is the problem.
Note that i can OC but I cant touch the Vcore setting in the bios only.

1:1 no problem with RAm.........i can OC to 376Mhz prime stable.
But i just cant touch the Vcore in the BIOS

F12............tried F13X also....still the same.

I only set the timing tight after prime stable.

Proc can OC and prime stable without touching the Vcore.

Just that everytime i touch the Vcore in the Bios things will go bad........

Problem is not my RAM la..............
even lose timing default speed at 200 fsb i change the vcore in the bios the pc will restart non-stop.
I.e. if din touch the vcore will be "Normal" when touch set to a voltage value like "1.3250V" <<<< this also will make the pc restart.

Is old ANTEC 430W true power.........

What is this fsb hole u all r talking about?

Anyway.....................even id i dun oc changing the vcore will cause restart.

Still the same.......i'm afraid.
anyway i am satisfied with my OC result now.
But i will slowly find out what is the cause of this problem.

Maybe is the proc itself.......

Cant change the vcorea at all. Change means restart.

My PSU like i have stated above.
Is old ANTEC 430W true power........

I have been giving the same answer to all who ask me to add vcore (change vcore means restart)

Yes when prime fail.
But in the sreenshot below.........nothing is added.

hmmm..interesting

Anyway here is the result of my OC 375Mhz default voltage in the bios.
C the voltages for those who say my psu not stable.

Yeah u r right. Stock speed change vcore = restart.

Pci-e voltage i also got increase but still the same.

I use Xigmatek HDT-S1283

Hahaha...........
I have tried 376 fsb but not stable.
actually the speed shown not correct also...........i set at bios is 375 but comes out 374.
Anyway at
375 fsb prime stable.
376 fsb 7 hours++ error.
380 fsb 1 to 3 hours error.
390 fsb cant boot window.
400 fsb cant boot in bios.

Yeah................i am very sure. that at stock fsb i cant tweak the vcore also.

Not yet OC change Vcore also restart la bro................been telling that since day 1.
Hit FSB wall at 200fsb??
Been OCing it now at 375 fsb.

BIOS i will try on that.

Memory setting not set anything also same ler...................
