PlayStation 3 is still extremely popular these days, which is why it is also a popular goal for hardware mods of all kinds. A user has made up for something very special and also achieves it: he lets his PS3 consoles run more energy-efficient, quieter and sometimes even faster.
Almost every PS3 could have run quieter and more powerful
That's what it's about:The PS3 is actually a closed platform, so the technology behind it is not so easy to decipher. Over the years, however, a broad pool of knowledge has accumulated that allows many modifications.
One of them demonstrated the Reddit user Tobi Esto, who deals with the deepest depths of the PS3 hardware due to his expertise in IT technology. He uses a so-called undervest mod to play on the PlayStation console without loss of performance.
This shows, for example, in,that elicits that of a modified console ten degrees less than the standard configuration:

What does that bring in practice?Since the chip does not reach so high temperatures, it runs less risk of using it. Alternatively, the fan speed can also be lowered, then the console runs a little quieter.
This does not cost performance, because the graphic chip does its work exactly with the clock rates that it should also achieve.
What is undervolting?
A chip needs a certain amount of power to work. A current voltage is created to supply the individual transistors with energy. At theUndervoltingIf the voltage is reduced, whereby it is avoided that at some point the chip no longer receives enough energy and becomes unstable.
For example, the German runs its hottest PS3 on the Cell processor at 1.125 volts and 1.075 volts on the RSX graphics processor. By default, Sony set the Cell CPU to 1.230 volts, the RSX GPU to 1.320 volts.
But why does Sony put on the values so high?
Although an energy -efficient and quiet console has many advantages, the tensions are chosen so that the processors work stable across all models.
In the Undervolting, it must be tested when the console will be unstable to find out the minimum of tension with which the chips run. With a super slim with 28 nanometer production, for example, up to 0.8 volts are possible, where energy efficiency is highest.
However, the energy gain again differs by how "good" the processor was made. Chips with a few flaws can be operated with significantly lower voltages than specimens with larger defects.
Can all of the PS3 undergrounds?
Although more durable consoles are a really fine thing, especially for collectors, but the process is quite complicated. You have to access the so-called SYSCON of the PS3-this is a chip that is responsible for the energy management of the console.
This can be read out via a uart port and the interface enables access to certain tables in which the tensions for the chips are stored. If these values are rewritten, the PS3 is operated with lower or higher voltages.
If the tensions are too high or too low, the console runs unstable and shows graphic errors or crashes. Since soldering skills are required to access the UART port, it is anything but easy to carry out the volt modifications.
There is now even a performance upgrade for the PS3
As the German writes, really good RSX chips are able to be operated with higher clock rates at lower voltage. Then there are more FPS in elaborate games such as Skyrim or Bioshock Infinite or Killzone 3 and the console runs less hot at the same time.
A thicker performance plus is even possible if the tensions in a stable area are increased together with the clock rates.
Getting the systems stable is becoming more and more tricky with every portion of Megahertz and Volt. And the longevity also suffers from it because the chips are stressed more. The "RSX Boost" project also has its disadvantages.
The undervolting sounds a bit "friendlier".If you want to try it, you can find videos on the YouTube channel from the German PS3 modder NSC Mods, for example. But be warned! The interventions are so profound that you can simply scrap your console.
Are you still gambling on the PS3? Would the mod be interesting for you if it weren't so complicated?
