TechEpiphany has decided to install the AMD Ryzen 9 5955X processor on one of the cheapest motherboards on the market, the Asus A320mM-K. Thanks to the official support of the Ryzen 5000 series chips in the selected A320 motherboards, the operating frequency of the flagship Ryzen 9 5950X processor on the mentioned motherboard seems to have reached five GHz while the PBO is active.
According to Thomhardor, it is a good thing that a core of 16-core processors achieves a working frequency of five GHz. However, low-cost 300 series motherboards have moderate power distribution subsystems that may not be able to take full advantage of a flagship chip like the Ryzen 9 5955X. For example, multitasking performance can vary by 20 to 30% on a cheap A320 motherboard compared to a more advanced motherboard.
This configuration is only possible because Asus has fully compatible the A320 motherboards with the Ryzen 5000 series with the new BIOS and the latest AGESA code, version 1.2.0.3C. Two months ago, a report was released stating that GIGABYTE and Asus had specifically started offering new BIOS updates to the A320 boards to support the latest AMD Ryzen 5000 series processors.
More specifically, the BIOS name contains the new AGESA code version 5862, which was released in November last year. Notes on this patch indicate that the AGESA update code will add support for the new processors, and to do so will completely eliminate support for the 7th generation Bristol Ridge A series and Athlon X4 series processors.
Oddly enough, the CPU support list does not show any updates to express support for the Ryzen 5000 series. However, we are sure that Asus has talked about support for the Ryzen 5000; Because they are the latest processors that AMD is currently producing. For some reason this feature is currently only available on A320 motherboards; This is because the motherboard makers have not enabled support for the Ryzen 5000 on better chips such as the B350 and X370.
Also yesterday, a report was released showing that AMD will not stop supporting 300 series chip motherboards yet. David McAfee“He and his engineering team are working hard to find a way to get Ryzen 5000 support on the 300 Series boards and how to run the chips on these boards,” said AMD, vice president.
Due to the age of the 300 Series motherboards, the smooth operation of the Ryzen 5000 is not an easy task. There are several blockers, including the IRM definitions and current capabilities of VRM motherboards provided for most 300 series motherboards. It is worth noting that the 300 series is significantly weaker than the B500 and X570; As a result, the boards could not transfer enough power to the Ryzen 5000 chips.
AMD does not test 300 series boards to be shipped to motherboard manufacturers when producing new AGESA code. This means that if the 300 series boards are updated to a newer version, all the stability of the new code system will be solely the responsibility of the motherboard manufacturer. For this reason, we recommend that you use caution when using Ryzen 5000 chips in the A320; Because bugs are more likely to occur on these older motherboards.
Keep in mind that most A320 motherboards have much weaker power delivery settings than B350 and X370 motherboards; Therefore, running the Ryzen 9 5950X at maximum power can be dangerous. To prevent this, be sure to do the necessary research and make sure your particular A320 motherboard has a powerful VRM system to control the Ryzen 5000, or at least turn on Eco mode if necessary.
