If you have a motherboard based on the file 300 series chipset, and want to buy Ryzen 5000, you may not need to purchase a new motherboard to install a new AMD CPU.
AMD Ryzen 5000 on motherboard X370
Apparently several users have been able to find Ryzen 5000 series processors running on 300 series mother boards:
- The first known case was using a motherboard GIGABYTE X370 in the beta version of the BIOS update with AGESA using a comprehensive Ryzen 5000 processor, assuming the Ryzen 9 5900X
- The second case was handled by Ryzen 9 5900X on the mother board ASrock A320 modifiedada.
The reason for this is that like 400 series mother boards, those 300 series can be upgraded to fit Ryzen 5000 into it, yes, as AMD does not provide official support for 300 mother boards, as announced a few weeks ago.
Apparently other motherboard manufacturers, such as GIGABYTE and ASrock, would have made the same motherboard BIOS Update used to upgrade 400 series chipsets to make it compatible with the Ryzen 5000, which it also does with 300 series, at least a beta version of the said review.
Let’s not forget that the release date is 2021, so it’s still a month and a half to go at least and they might decide to withdraw support for the 300 series at the last minute, because the initial interest of these companies sells as many motherboards as possible and be economically interested in what people don’t keep the motherboard same for many generations of CPUs.
Why is the limit set by the artificial AMD?
If we look at that Zen 3 uses the same IOD as Zen 2, at least when we compare the Ryzen 3000 vs Ryzen 5000, because both have a chiplet-based suspension. Surprisingly, all motherboards supported by Ryzen 3000 (Zen 2) are not supported by Ryzen 5000 (Zen 3).
The inconsistency would make sense if we were talking about a clean slide in what is the structure that connects the CPU and motherboard, but it turns out that apart from chiplets containing CPU cores and their cache, all other CPU-based CPUs were similar to those based on Zen 2. This makes that limit set by AMD on 300 series chipsets in installation limitsas there is no reason at the hardware level limit to prevent the use of Ryzen 5000 on 300 series boards.
Keep in mind that AMD sells not only Ryzen CPUs, but part of its business is the sale of chipsets to various motherboards compatible with their processors, which are sold by AMD to these manufacturers, so that there is a commercial interest on the part of AMD in reducing compliance.
