RED 9 3950X on the A320! What happens when you save on the motherboard?



We made the combination totally unbalanced to show the impact on performance.

In one of those articles on things we do just to see what is going on but which we definitely do not recommend doing, we tried to completely balance the balance between the CPU and the motherboard. And the Rizen line is perhaps the most impressive to do so.

The AM4 platform is the most impressive we've ever seen in a variety of configurations.

Due to the long-term support of the AM4 jack and the significant increase in core count during this period, this socket supports from dual core processors to 16-core, 32-thread models! Unprecedented scalability in the mainstream segment makes Ryzen 9 3950X's "monster" fit into a motherboard designed several years ago, with a chipset that would have a maximum of 8 cores when first imagined.

The same outlet that fits the 16-core processor also has dual colors.

Because we have such an impressive window, we decided to do an extreme test. We are rolling out the latest release of the AMD processor to run on the A320 motherboard, the most basic chipset available. In theory, it is not ideal to outperform Ryzen 3 for this motherboard, as it has many basic power structures. What we're going to do here is put 4 times more cores than that.

We put it into action for a crazy experiment Asus A320M-K / BR, a card that usually appears a lot in videos for being a computer card … with a budget of up to $ 1.5 thousand! No problem, the Ryzen 9 3950X will cost you 3x more than all this budget!

Surprisingly, the system was able to boot. This is not possible, according to the tables presented by AMD itself during the Ryzen 3000 and X570 presentation:

But as has happened at different times, manufacturers seem to have some freedom to ignore some recommendations and to somehow mess up the ecosystem, giving compatibility between components that shouldn't work.

On, but the effects are already evident as soon as we open the CPU:

Only four cores are active. Basically, our Rosen 9 woke up from Rosen 3! Without the support for the Ryzen 3000 on the A320 card, even with this card in AGESA 1.0.0.3, we can already see the miracle that this system is not even included.

Only the call was already impressive

This is not the first time we have seen a CPU limited by the motherboard. Intel's K-line is not overclocked unless it is combined with a Z-line card, just as Ryzen is also OC locked if used on the A320 card.

So, since we've come so far, why not consolidate all these fake running tests? So, we have the real picture of "you shouldn't have done it, you did it".

In situations where multiple cores don't make the difference, as in some games, until the results are bad, but in performance applications you may be completely depressed by the loss of performance of Ryzen 9 running on an incompatible motherboard.

This experiment is drastic, but it raises a relevant question: balance your system, even when some components do not directly affect efficiency. The motherboard should have a structure to support the CPU power and resource needs.

The experiment was fun, but it confirms that it is ideal to strike a balance between the components of your computer.

It's usually not a difficult job. An input processor works well on the input platform, while a powerful processor requires at least something intermediate. A case like the Ryzen 9 3950X, however, no doubt. You better go to the top of the line card to make sure it reaches its full potential. Other situations, such as overclocking or heavy workload over a long period of time, also require a harder board. The extra stability will be an important differentiator during the lecture.
