DS3 wont hold an OC....

[TurnX]

having some issues trying to get any sort of overclock out of my DS3. Pretty much started by following this guide:

http://forumz.tomshardware.com/hardware...erclocking-Guide-v1-ftopict197995.html

Mainly to get an idea of what to disable and where to start as I have only had experience OCing AMD stuff several years ago. Ipretty much skipped step 3 of the guide as I dont really want to mess with voltages unless I have to. I want to get the most out of the stock voltages first. My problem starts when I turn the CPU Host Clock to manual and set it to 333mhz, the starting point the guide sugests. Once I do and try to reboot, my PC will just sit with all the fans at full rpm and not do anything. I then have to clear the cmos in order to get it to boot.

Like I said you can pretty much describe me as a noob at this as I havent done a C2D OC before and the last OC I did was years ago, so please be kind if I just made a stupid mistake. Any help is apreciated. (Specs are in my sig, using F8 bios)

Well going from 266 to 333 all of a sudden is a pretty big and unsafe endeavor. Why don't you try 280 to start out with and increase in 5 MHz increments? I'm about to start trying to see what I can get out of my DS3 as well.

I say go the other way. Bump up the voltage to a flat 1.35 and try 401Mhz.

Well I think I may have fixed my problem. I first switched back to the F7 bios. Once I did that I made all the same changes as before, but I turned voltage optimization to auto. Once I did that I was able to boot fine with an OC, currently at 350mhz FSB Prime95 stable overnight. Not 100% sure if setting the voltage optimization to auto fixed the problem or if it was switching the bios. Guess i'll find out in a couple days when I need to adjust some of those voltages to get a higher FSB.
