Hi guyz.This is a really strange problem that i have faced last night.

My cpu is oc to 3 GHZ rite now(model - E6400).i had no stability issues for abt 1 and 1/2 months.Suddenly uesterday nite,my machine refused to boot showing a message "OVERCLOCKING FAILED".

I went to bios and lowered core clock by 5 and machine booted successfully.after that i again increased clock cpeed by 5 and rebooted successfully.machine also passed ORTHOS stress test for 8 hrs.

Note:- I didnt change anything except the core clock speed.

I really am confused why this strange thing happened.Plz help me out.

Thanks in advance:).

noone there to help me?:(

Are there any improper shutdown when the machine was booting or any hardware failure before?

First save your profile in Bios:)

Usually this happens due to above reasons, I also have faced your prob, but if your PC is running smoothly then nothing to worry about :)

Because of power fluctuation: this may damage your CPU, HDD, mobo.
Our Computers want a steady power supply and very good earthing

UPS rectifies all these and give us a steady flow of current

Your current PSU should be more than enough for this configuration. Get one UPS, apply some thermal paste. To keep the overclocked CPU stable, replace CPU's heatsink with a copper heat sink from antec/coolermaster.

my ZALMAN CPU Cooler has copper heatsink.So there s no need for going another one.

i ll definitely use the thermal paste regularly :).
thanx for ur suggestions.

will 650 watt be sufficient?

My suggestions, don't burn so much money if ur area doesn't have any "current off"
There's no power prob also in my area, I use APC 550vA for safty

If u feel u need it, then u can buy :)
