Hello everyone :hello: ,
I'm completely new to overclocking and i'm having some problems with my pc.Ok let's get to the point straight,When i turn my pc on,the power stays for 2/3secs then it automatically turns off and then powers up again without any problem.There is no other issue(s) with my oc.I've done some stress test using prime95 and OCCTPT2.0.0.a for several hours and it shows my oc is stable. Below is my current system config,

CPU: C2D E6750@3.20GHz (G0),FSB 400MHz,Multiplier x8.0,Stock heatsink.
MOBO: Asus P5KC(bios 1001)
RAM: 2x1GB OCZ PC-6400 800MHz(stock),4-4-4-15(stock), DRAM volt 2.10(stock)
GPU: Ati Radeon HD3850 @720Mhz/1054MHz
PSU: OCZ Stealth extreme 600w

If it turns on for a couple seconds, then shuts off, it's probably the bios auto reset feature at work. It automatically resets the settings to default because the OC settings were unstable.

What mode are you using for Prime95? "Blend" mode?

Run CPU-Z to find out what voltages/bus speeds/RAM speed you're actually running at.

Thanks for your response mondoman...

I've switched back to default settings, but, I've seen one thing though,when i change Ai Overclocking mode to [Manual] (without changing any sub-settings) it does the same thing!...Is there any particular problem with my components?...And also my hard drive (IDE) crashes sometimes and reboots the pc saying 'Detecting Drivers...'...Is it for the high FSB I was using ?

Sorry for lots of questions :( I'm confused :(...

I will try again to overclock my pc after more studies on 'overclocking' :)

You certainly don't want to use the MB manufacturer's overclocking software, because many do bad things like raising the CPU voltage way too high without telling you. Do everything on manual in the BIOS.

The manual/auto overclocking mode under JumperFree configuration on P5KC is named ai tuner/ai overclocking (can't remember which one was it :whistle: )...There is 3 sub settings on ai tuner/ai overclocking, [Auto][Manual][N.O.S].

I used the manual option and configured FSB/DRAM Freq/DRAM timing/DRAM Volt/CPU volt/CPU Ratio/PCIE Freq myself...I used that mode for overclocking... :sweat:

yeah ... i did it from the bios...Do you think my IDE hdd might be the reason for the problem? coz i read somewhere that increasing fsb affects IDE hdd for higher pci buss speed or something...any advice?

You definitely do not want to change the PCI (normally 33MHz), PCIexpress (normally 100MHz) and other bus speeds from normal. There should be one or more settings in your BIOS (they vary among different BIOSes) to keep those busses locked to normal speed.

yes i have settings for PCI-E frequency and i locked it @ 100Mhz...But i can't find any PCI frequency or any other setting to lock my pci buss speed...I'm thinking of getting an SATA HDD :( ...
