I'm trying to OC my E8400(3ghz) to some safe speed like 3.6-3.8ghz using stock cooling and my first attempt has failed. I've red a few topics on what to do and did but it didn't work. I set my BIOS to this settings:

CPU Host Frequency: 400
PCI E Frequency: 100
System Memory Multiplier: 2
CPU Voltage: 1.3V

My system didn't boot after this settings. It booted itself twice and at the third boot the system was reverted to old settings.

After this I only changed CPU Host Frequency to 400. It booted but my Windows was unstable. Corrupt files, program crashes and finally a BSOD. I reverted it back to 3ghz.

What am I doing wrong?
 
Try bumping up the voltage on your RAM. I have an E8400 with Crucial memory. The default voltage was no where near what the manufacture recommended. I am pushing 2.2v to my RAM. It seemed high to me so I contacted Crucial and they told me I could damage the RAM if I put less than 2.2v into it. To get my OC above 4Ghz I have to use 2.25v. I can do 3.8Ghz with 1.29 CPU voltage and 2.2 RAM.
 
Got to agree...set ram voltage manually (doesn't have to be that high yet); and start @ 3.2 for the cpu; and work your way up.
 
That's a Gigabyte board. First thing, turn off the memory enhance to Turbo.

Set it to standard!

Increase CPU and memory voltage as well. 1.4v vcore should not hurt for a quick test to see if it provides stability and to check heat. Set vdimm to 2.0 at least.
