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)

northbridge voltage did you increase it?

fsb hole means there are certain of fsb which cause d board can't boot no matter what u do...

correct me if i'm wrong, intel noob here...

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.

so u mean at stock....but u change the
vcore from normal to ANY number = restart?

try pcie?
i think cant do anything....mobo prob maybe
what hsf u use ?
temp quite high
then i think u settle a 3ghz stock oso enuff la

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.

ic.. u set vcore = restart..
u sure u stock FSB and tweak vcore straight restart?

or only after 273Mhz FSB just so?
my experience told me MY MSI board after 273Mhz just cannot set vcore at bios.. but once i BSELed processor, it FIXED self restart on P35 and can set voltage after even 360Mhz...

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

even i using caplang RM40 "NOW" power supply also oc me E2160 to 3.25Ghz

thats depends on ur preference. if u are a heavy gamer who are gaming in an oced rig for few hours, then a better PSU is needed.

anyway, if keep restarting, maybe ur mobo hit the FSB wall??

Sometimes newer bios doesnt mean better compatibility or whatnot.

Try changing it to older bios. Try one or two older ones. If problem persist, either RMA or get a new board.

and also the memory setting. Set it to unlinked and leave the memory speed and voltage as it is. Memory setting can cause problem even if u think it doesnt. Happens to me.

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...................
