Earlier this month it became known that AMD will release an update of the microcode of AMD Ryzen processors, which should improve memory support.

Yesterday AMD made available the version of AGESA (AMD Generic Encapsulated Software Architecture) 1. 6 for motherboard manufacturers. One of the main innovations was the support for the DDR4-4000 memory mode, and the step of changing the frequency is 133 MHz. It's no secret that the new AMD CPUs respond well to increasing the memory frequency, so that the ability to use the fastest sets with the possibility of raising the frequency to very high values ??should obviously come in handy for enthusiasts.

In addition, the new version gives access to 26 new registers of integrated memory controllers for new processors. Among other things, they will allow you to achieve higher memory frequencies during overclocking without the need to change the BCLK frequency.

In addition to working with memory, the new version of AGESA adds new capabilities to manage graphics subsystem resources. In particular, it adds support for the mode PCI Express Access Control Services, which allows you to manually assign graphics cards (if there are several of them in the system) to specific logical containers (IOMMU groups). In the future, each IOMMU group can be allocated to a particular virtual machine.

Simply put, if there are two or more graphics cards in the system, one can be assigned to the main machine with Linux, and the other virtual to Windows. BIOS updates for motherboards using the new version of AGESA will be available next month.
