- Overview of the problem
Basically I'm psyched to try to get my system to 4.0GHZ after I saw several people doing that with an E8400 at around 1.3vcore. What I have found is that I cannot keep it stable at 3.6, I have about 30 seconds at 3.8 and instant blue screen at 4.0 (Testing for FSB walls so I tried several different clock speeds) well I'm giving up random trying and asking for your help.
- Full description of the problem and symptoms
I've set the Vcore at 1.36 and for some time it was relatively stable at 3.7GHZ, then I started getting random lockups and blue screens, I reset to stock and it became stable again. Now I want to try again to hit 4.0.
Now I have done 24hours of memtest 86 with my ram so I'm fairly positive it is in working condition, (on another computer though if that makes a difference) although my sets are mismatched (both are Ballistics PC2-8500 just they have different heat spreaders and one set is rated at 2.0V and the other is rated at 2.2V, to be safe I run it at 2.2V, as well one sub timing is different but I run it at the slower one)
Basically I would like to know anyone else settings with a similar set up, I'm on bios 1006 and here are the settings I used to be semi-stable at 3.7, although I can no longer duplicate that. Semi Stable meant about 4 hours of Orthos Stable and I used this setting for over a month without issue.
Basically Now I cannot have anything stable, when entering at 3.6 it either bluescreens or completely locks up, at 3.8 it will get to the log in page then bluescreen, and at 4.0 it will not show the loading bar for windows. I have good cooling (8 fans and Freezer Pro 7) I just want to move to the next step everyone seems to be on.

The first setting is what I had it on and the others are what it can be, I`m not sure what everything means and I went by a random guide I found on the internet. If you can tell me what needs to be adjusted or what I need to do to make this happen it would be helpful
Only changes made during semi stable overclock were installing Ubuntu.
