well i did it i blew my new system.

I5_2500K. 0verclockd to 4.5
Asus P8Z68-V.
Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz.
Thermaltake toughpower 750w PSU.

got every thing running last night.
core voltage was at 1.3v
decided to see how far i could lower the voltage.
went back to 1.3v but instead of the 3 i hit 8.
set to save and exit and noticed it to late.
so it tried to reboot at 1.8v.
screen came up but at bottom it said cpu voltage error press f1 or something.
pressed f1 but it hung befor i could get into bios.
now i get nouthing on screen just a black screen video is not imputing.
when i start the computer all fans start up including the cpu fan.
then i get the red mem ok light stay on.
tryed pressing the mem ok and it goes through its series 3 times i think.
then it goes back to red.
tryed resing the bios with the jumper.
tryed taking out the battery and unpluging the pc from mains.
nouthing.

any one no how bad ive screwd up ?
have i blown the mother board ?
have i blown the cpu ?
have i blown the memory ?
or have i destroyed the lot ?

im absalouty gutted right now and i fear the worst ive blown every thing.
please let me no guys thanks for reading.
 
Should have unplugged it and reset the bios with the jumper as soon as you realised.

Probably just the cpu gone, intel will probably let you rma it as they can't tell it's been damaged through high voltage.
 
Don't panic,if oc failed by asking you to press f1 chances are it didn't apply settings

Power pc off completly and take out mb battery,leave out for 30mins or overnight,then put in and try booting up,it will reset BIOS to default so don't worry
 
Ouch :(

How on earth did you manage to hit 8 instead of 3?

Does sound like CPU has gone, alternatively it could be the memory. I recall during my first build with a P8Z68-V I was getting the red memOK LED constantly, turned out it wasn't picking up the ram as I hadn't seated it correctly. So could be worth a try grabbing a cheap set of memory to try!

it was late i was nackerd but your right how on earth indeed.
please dont scold me i no im a nob.
i just need to no whitch is the most likely.
 
Try with one stick of memory,test each slot one by one with a single stick,it should boot up from any slot,then test other sticks one by one
 
If you've tried all those things it only leaves CPU or mb as faulty/damaged,would be good to test CPU in another board if you can

i have no way of testing any of this or i would have been abile to find out.
my self i think i have fried the cpu.
but i dont want to lay out £200 on a new cpu and find out its the mobo or mem.

Only thing you could do is take your mb or chip or both to pc shop or friend with same mb and test them,then rma either the mb or chip

Thats what I would do.


1.8v :eek:

Doing this when it was late and you where nackerd is not a good idea but I guess you have learnt a valuable lesson. Hope you get it sorted.
 
intel normally goes of the serial number printed on the chip or the box regarding rma,same for motherboard,but try and find someone who can test the chip first so you know which part is at fault,i doubt its both the chip and motherboard
 
Well, there has to be someone from here in london who could help you out...

... then you can get on with the process of RMAing.



That wasn't what I was suggesting.
