AMD Socket AM5 BIOS Update AGESA PI 1.2.0.2


AMD Ryzen desktop processors running on AMD Socket AM5 platforms now have the updated BIOS firmware, AGESA PI 1.2.0.2.

Use the new BIOS firmware update, AGESA PI 1.2.0.2, if you have an AMD Socket AM5 motherboard with an AMD Ryzen 600 series chipset or one of the new AMD 870X motherboards, to maximize the performance of your AMD Ryzen 9600X and 9700X processors. Core-to-core latency improvements are also advantageous for desktop Ryzen 9 9000 series processors.

You may contribute to improving performance with the AMD Ryzen 7 9700X and Ryzen 5 9600X's new, guaranteed 105W cTDP.

With a basic Thermal Design Power (TDP) of less than 65 Watts, efficient performance was the aim for the AMD Ryzen 9600X and 9700X CPUs. But what do you know? By applying the 1.2.0.2 BIOS update, you can utilize your AMD Ryzen 9600X and 9700X CPUs at 105W TDP without compromising your warranty. To enable the 105W cTDP, simply activate it in the BIOS update 1.2.0.2.

These processors have been confirmed to run at 105W since their launch, thus you won't be pushing them beyond their designed limit. Multithreaded workloads will gain the most from this change, however less-threaded programs might also profit from it. Always remember that with great power comes great responsibility, so make sure your cooling system can handle the higher temperature limit that 105W offers.

Gains in Latency from Core to Core

This was largely brought on by a corner case test that demonstrates that two transactions are needed to read and write data shared between cores on different parts of an AMD Ryzen 9 9000 Series CPU. But with the launch of the 9000 series, it has been attempting to maximize this.

The most recent BIOS update, version 1.2.0.2, has successfully cut the number of transactions in half for this use case. This upgrade is meant to help reduce core-to-core latency in multi-CCD devices. This won't really affect most programs, although users that play heavily threaded, latency-sensitive games without experiencing core parking might notice some improvement.

Motherboards for AMD X870/X870E

The latest generation of AMD Socket AM5 motherboards is now available, starting with the X870 and X870E. Both offer full-speed PCIe Gen 5 compatibility for both graphics and NVMe storage simultaneously, which is appropriate given that a new generation of graphics cards is set to be released soon. Additionally, taking inspiration from the 600-series motherboards now available on the market, they were developed with USB4 as standard and support for overclocking.

DDR5-8000 Assistance with Expo

At the moment, enthusiast-class RAM with faster clock speeds is supported. We have received assistance from motherboard and memory manufacturers to enable DDR5-8000 EXPO support. This greater clock speed can be seen in some latency-sensitive games as the moment when the 1:2 memory ratio starts to shift in favorably.

Though it may not be suitable for everyone, DDR5-8000 is an excellent option for enthusiasts and overlockers who enjoy pushing their systems to the limit.

In brief

AMD has improved the functionality and performance of AM5 motherboards with an upgrade to the BIOS. Thanks to the improved power consumption options, users can now utilize Ryzen 9600X and 9700X CPUs at higher TDPs without jeopardizing their warranty. Additionally, it lowers core-to-core latency for CPUs in the multi-CCD Ryzen 9 9000 series. Included in the upgrade are new motherboards, the X870 and X870E, that enable full-speed PCIe Gen 5 and are compatible with DDR5-8000 EXPO for enhanced overclocking capabilities.

FAQs

Does my warranty get voided if I overclock my AMD CPU or memory?

Even if AMD software or hardware has approved this behavior, any applicable AMD product warranty will be void if AMD CPUs or RAM are overclocked or undervolted beyond AMD's specified specifications. Furthermore, this can make any warranties offered by the system manufacturer or reseller void. Users assume all liabilities and hazards associated with these kinds of activities.
