Overclocking help

Hi everyone, I tried to overclock my 2.4G processor to run at 2.6G but now my system fails to boot up. It just hangs in the MB manufacturer logo and doesn't even allow me to go back to BIOS to reverse the setting I have made. One thing I have noticed, the HDD light on my casing is always lighted up after the change. I was wondering if there is anything to do with the HDD. Before that I increased the freq from 133MHz to 144MHz with the multiplier at fixed 18. Anyone know what could be the problem and how to solve it from here? Thanks!
 
try to increase the vcore by 0.025V, about 4 times, that's 0.1V.

don't think hdd has to do something with this.

when you increase fsb don't go to 144MHz instantly, increase it by 5 or less.
mine didn't want to boot

what cpu exactly you have?
 
Hi filip-matijevic, I managed to the problem. Can you advise me the purpose of increasing the vcore? Coz from my understanding, overclock is based on this calculation

cpu speed = multiplier * FSB freq

I tried to increase the freq coz the multiplier is locked. To do overclocking, what other issues do I have to look into? Thanks for your suggestion of increasing the freq progessively. It is helpful.

My system is as follows:
-intel 2.4A processor (533MHz FSB, 1MB L2 Cache)
-80G Seagate sata HDD
-PC 3200/400 Kingston 512 MB RAM CL 2.5
-MSI 865GM3-LS motherboard
-PSU 400W

I wish to overclock it to 2.6G. Please advise. Thanks a million!
 
To get back into your bios, shut your PC down and disconnect power then open your case and look for a circular silver/stainless steel colored battery. Remove it for half a minute and then put it back, this should reset your bios settings. Power your system up and you should be able to enter bios without any problems.

You will probably need to increase the voltage to both your CPU and your memory.

question: What make of memory are you using?

There is also a way of clearing cmos by a jumper, read your mobo manual about clearing the cmos so you can know which jumper cap you need to move to the CLEAR setting, when you move it hold it for a few seconds and then place it back where it was

increase the FSB by 1MHz and when your system becomes unstable increase the vcore for 0.025V and then continue increasing FSB by 1MHz and when it becomes unstable again increase the vcore again but don't do this over 5-6 times cuz you don't wanna burn your cpu cuz higher the voltage higher the temperature

may try 5mhz at a time, doing 1 will take to long, and you get the same results anyway
