OC in AMD Overdrive not saving.

[Danny K]

Hey there,

I am having some problems overclocking my CPU, the overclocking itself worked for me but after rebooting my system the saved settings were gone and my CPU wasn't overclocked anymore. This was in AMD Overdrive and I know it's better to overclock in BIOS but I'm afraid I'll do it wrong.

I ticked the box to apply the saved settings on rebooting but it didn't.

Any idea how this happened?

Although I highly don't recommend using Overdrive for overclocking, what you probably need to do is click the little green button at the top right once which will change it to a red circle around it. That should hold the settings.

This didn't do the job, thanks tho.

I'd love to ditch software overclocking but I'm not sure how to do it in BIOS. So I'm too scared to touch the BIOS at all. 🙁

Here I am again, it seems I figured out how to overclock in BIOS. It was really easy I was just afraid to mess something up. I'll never use Overdrive again. Thanks for your help though!

So now that you've discovered the BIOS, there are some things you need to be aware of. Just changing the multiplier or even the multiplier and voltage, to achieve the clock speed you're looking for is the least of what needs to be done. You still need to verify thermal limits, stability and tweak your BIOS to account for the increased voltage loads to the CPU to offset vdroop and load line calibration.

You'll probably want to configure a custom fan profile for the case and cpu fans.

To establish compliance with the thermal limits for your CPU you want to run Prime 95 on small FFT's for 10 minutes. If you don't exceed the listed maximum temp for your CPU within ten minutes, it's unlikely you will and should be ok in regard to temps. Next you need to run Prime95 on small FFT's for 24hrs to verify that the overclock is stable and that you are not introducing small errors into your data that will eventually render your OS and saved files useless or simply wreck your core kernel stability.

Along with the loads imposed by your overclock, you need to compensate by setting the load line calibration to enabled and then to an appropriate setting. Here is why:

If you're using the EZ or similar BIOS mode to overclock, you don't want to do that. The system uses much higher voltages to maintain stability when overclocking this way compared to using the advanced mode and configuring the overclock manually, which isn't much, if any, harder than using the windows utility or the EZ modes. If you'd like to tune your rig in properly let me know and also post your system specs so I can pull up your BIOS menu options and give you accurate recommendations based on your available settings.
