Voltage

[remotehugger]

I guess i just cant grasp this. Cpu-z says my voltage is 1.392. In my bios it says normal voltage is 1.325. I am at 17.5 multiplier and havent touched the voltage. I can run prime no problem. I up to 18x and it crashes as soon as i start prime. So i try to up my voltage in my bios and as far as i can tell it can only go in .025 increments. So i add .025 which i assumed brought it up to 1.350, right ? Cpu-z still says 1.392. Can someone please help me with this. I am getting a little flustered. With Amd Overdrive it autoclocked to 18.5x with a voltage of 1.48. At least thats what Overdrive said. If i am not explaining this well please let me know. Sorry about the book length.

Use BIOS to overclock if you can, software isn't the best overclocking method.

Actually a little more info would be helpful. But let's just take what we have. You've used AMD overdrive, which is good for AMD overclocking, its a helpful tool.
I believe, although I could be wrong, that overdrive saves your profile and it launches a program when windows starts called AOD helper. I believe its the job of this "helper" to save the profile and create the settings, even though Overdrive is not running. Thus when in bios, you are seeing what is set by the bios. However when you boot to windows, AOD pushes the new settings. I think that accounts for the difference in voltage readings you are experiencing.

Thats what AKM800 was saying, that most overclockers prefer to bios overclock as this will be more stable in windows than software. Conflicting information from the bios and windows software will not give the best results.

Here's an article on AMD overclocking:

As the article suggests, AMD overdrive is a good place to start, as it is helpful in determining the max multi, max front side bus, and other settings instead of changing a setting in bios, booting back to windows, and leaving windows again to change bios.

Once you have a good idea of where you need to be from your AOD settings, then reboot to bios to fine tune and set everything accordingly.

As for the AOD helper, I simply disabled it from startup via msconfig, as it never really worked properly for me anyway! 😉

BTW, after configuring windows to not start AOD helper, I noticed that after subsequent sessions of AOD, the helper once again defaulted to running at startup. I suppose a better option would be to disable AOD helper via the services configurator.

Control panel/Administrative tools/services in XP.

Thank you buzz. I got it up to 18x with my voltage at 1.408. Is that voltage to high ? Im oc'ed to 3.6Mhz. Temps in speedfan say -temp 1 45 temp2-61 temp3-60 core-56
