Overclocking - AMD OverDrive Not Yet Mature, Continued

AMD Phenom 9600 Black Edition: New Hope?
By

We conducted this test on an ASUS M3AA32-MVP Deluxe (rev 1.02G) motherboard using the current 0801 BIOS published on 26.12.2007. The Phenom CPU we used is a final version, just like any other you could buy in a store.

When we attempted to raise the multiplier of our Phenom 9600 Black Edition from 11.5x to 12.0x, our computer crashed. But changing the same settings in the BIOS allowed the system to restart without a hitch, boot Windows Vista, and run without a problem.

The Gigabyte GA-MA790FX-DQ6 board, using the current F3 BIOS (1.12.2007), also crashed when we used the OverDrive utility.

The settings from the OverDrive utility are not saved to the BIOS. Thus, if you want to change the settings permanently, you'll need to note them down with pen and paper and then set them in the BIOS manually. However, since the settings don't seem to have the same effect across various boards - as we realized with our ASUS board - that calls into question the general usefulness of the tool. You can choose to have the tool start up with Windows, which will ensure that the settings are applied at every launch. Even this is not a 100% guaranteed method, though.

AMD will still have to invest some more time and effort into this tool before it works reliably and provides the desired results. For now, we can't with a clear conscience recommend using the OverDrive utility to overclock Phenom processors, since its functionality is still rather lacking. Even though we used specially adapted versions provided by the motherboard makers, we still experienced crashes and lockups. In the end, we decided to overclock our systems directly through the BIOS.

Voltage settings in theOverDrive tool

That's not to say that the AMD OverDrive utility does not offer some benefits, though. It allows the user to adjust the memory timings from within Windows, to monitor and change voltages, and keep an eye on temperatures. Still, even in the newest version (2.09), the tool was unable to supply correct temperature readings.
