I have not upgraded the bios since I got it. I should check and see if there is an update. As I am a new to this, I would not know, but what I have read says not to use turbo. So your saying I should put the turbo multipliers to my desired overclock. I guess that makes sense. I will try that too. It is an Msi p67 gd53 I use occt and prime 95 to test. I also leave it at that clock speed for a few days just to see if it remains stable. Also I just tried at 4.6 and it works tested so far. I also have to say thank you for the help. This is exactly what I needed. I will check to see for responses. I will let you guys know how I do with this new information.
