BrazosTweaker

This is the interface that you’re initially greeted with when you launch BrazosTweaker. The core clock readouts are located just above the row of tabs. These can tell you the current P-State, the small number, and the current clock, the large number in MHz, of your APU. Something to take note of is the “Always on top” check box, which is useful when you’re running multiple stresstests and modifying voltages. Also, I’ve highlighted the voltage setting box, which is probably the most important setting that this tool can change. Just above the voltage selection box is the clock dividers which are user configurable. So if you’re looking to under-clock your APU in addition to dropping its voltage this is one way to go about it.

BrazosTweaker includes a couple oftemperature monitoring services including one that reports the Northbridge temperature. It also has an extremely useful drop down menu that instantly changes the Windows power plan. This allows you to force the P0 state on both the CPU cores and the Northbridge by selecting the High Performance plan.

What we’re looking at here is the status tab. It’s basically a debug page. The two useful options hereare the “Reset P-States” button which brings everything back to their defaults and the “Log now” button which creates a rather self explanatory log of the applications status. From here the rest of your experience with this tool will depend on how over-volted your APU is and how far you’re willing to push the settings down.

Background with the creator

We had a chance to get some backgroundon these tools from their creator Sven Wittek. We asked him about the development these tools, his motivations for creating them, what his plans are for these tools as we move into the future.

Basically I was using a tool, RMClock in the past to fine tune and monitor the temperatures of my older desktop CPUs. Sometime ago, I got a laptop with an AMD Phenom CPU. I wanted to reduce thetemperatures and increase battery life. Since RMClock was not available for AMD Phenom any more, I was looking for an alternative. I found a tool called PhenomMsrTweaker, which I really liked after a while for its usability and the built-in service. The same tool is running on my desktop now and I’m very pleased with it.
A little later in April 2011, I bought a netbook with an E-350 APU. I liked thisnetbook a lot and I was looking for further improvements in battery life with lower temperatures, but there was no tool yet to do that in an easy way.

Because I already knew that the PhenomMsrTweaker tool is OpenSource code, I decided to try my luck and get the PhenomMsrTweaker adjusted to fit the Brazos platform. I’m working for AMD as product engineer, so I’ve a rough idea, of how to get started,but I was really inexperienced in the programming languages that it used (CSharp and C++ combined) and the details of how to control the processor registers (a task that is not really close to my daily work at AMD). With the help of programming books, the BIOS developer guide from AMD, and a lot of my free-time I finally got an initial program, which was almost fully working. The first versionswere still called PhenomMsrTweaker, but sometime later I found Google Code and started the BrazosTweaker project there. I made some posts in German and US forums to get some feedback, and people found the program quite handy.

After that, a few people started to ask if I could try to get the same done for Llano APUs. Since I haven’t got a Llano system, I tried to adjust the program blindly and letother people give it a shot, while using their feedback to wipe out bugs. Unfortunately that didn’t work out too well. The first versions of FusionTweaker were only partly working. Luckily in September, I had the chance to get my hands on a Llano notebook for a while to fix bugs. Now the released version is much more stable, but it still has some minor issues.

A few weeks ago, I started to...
