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.

ur ram divider?

hmm....what about trying to flash ur mobo to the latest bios?

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.

erm....what about running ur ram with CL5 loose timing?

if still cant maybe u may wana try ur proc on other mobo to see if its faulty?

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........

erm....is ur ram tested for stability after tightening then?

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.

have u tried to set the vcore even higher? coz when pc keeps restarting...it means either ur vcore is not enuff or ur ram timing is too tight or not enuff vdimm....but in ur case i think vcore not enuff...

Tried adding more vcore? Good HSF?

ahh....or the infamous fsb hole on P965

Add +0.1v to FSB overvoltage and +0.1v MCH overvoltage. Thank me if that solve your problem

what bout ur PSU??

i think its the infamous fsb hole in the 965 chipset bro... coz he has tried everything but it doesnt work.. what possibly can he do?

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.

bro vacs, any improvements to date ? few days no news.....

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.......

did you miss out the NB voltage,
you should juice it up since you are running on higher FSB

try adding the vcore or mybe due to unstability of ur psu..good psu???

cha vcore and vdimm

cha vcore to 1.425 and vdimm 2.1

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)
