Need help overclocking intel E2180 on a gigabyte 945GCM-S2L mobo

1. Check rail PSU with multi meter, is PSU enough for OC
2. Replace New HSF CPU aftermarket
3. check HDD with HDD generator if broken this can repair
4. Check RAM with memtes86+ if broken Replace New RAM
5. OC step by Step if BSOD see massage information
6. Increase Vcore + Increase VDIM

after decreasing the fsb (260 or less) the hdd gets detected and it boots up normally and everything is fine, but once i try to increase fsb the same problem again.

could you tell me what to do in detail.

You are at the limits of your stock cooler.

This should be your first stop.

It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.

Go through the guides. Then go into the BIOS and change the System Memory Multiplier from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB.

If you are at your stock FSB of 200 MHz, your memory clock should be at 400 MHz.

Download CPU-Z to check your FSB:RAM ratio.

Overclocking RAM does not accomplish much in a Core2 system.

ok thanks for the info, i'l try n post back.

guys need help, i dunno what went wrong when i was setting up the bios.
i am not able to boot my system, not even able to get into bios.
when i switch on the cpu only the light goes on and the fans are spinning, but nothing is being displayed.

can anyone help me, plz, plz, plz.

What you need to do is unplug the computer or click the switch on the power supply. Open your case and look for the battery, near it somewhere should be a 3 pin jumper. If it isn’t near it then you’ll have to look for it, your manual will show you where it is. Now move the jumper to the opposite 2 pins and wait a few seconds, then put in back to the original position. You should be good to go, you will have to input your settings again unless you have a profile saved.
