The new version of microcode for CPU AGESA Ryzen became available to motherboard manufacturers
In the beginning of the month it became known that AMD will release a firmware update AMD Ryzen, which should improve memory support.
Yesterday, AMD has made available the version of AGESA (AMD Generic Encapsulated Software Architecture) 18.104.22.168 for manufacturers of motherboards. One of the main innovations was mode support memory DDR4-4000 and the step of changing the frequency is 133 MHz. It is no secret that the new AMD CPU well respond to the increased frequency of memory, the ability to use the quick sets with the possibility of increasing the frequency to very high values obviously should be useful to the enthusiasts.
In addition, the new version gives access to 26 new registers integrated memory controllers of the new processors. Among other things, they allow to reach higher memory frequencies during overclocking without having to change the BCLK frequency.
In addition to working memory the new version of AGESA adds new capabilities for managing the resources of the graphics subsystem. In particular, it adds support for the regime PCI Express Access Control Services, which allows you to manually assign the graphics card (if you have more) specific logical containers (groups IOMMU). In the future, each IOMMU group can be allocated to a virtual machine.
Simply put, the presence of two or more graphics cards, you can assign one main Linux machine and the other virtual Windows. BIOS updates for motherboards that use the new AGESA version will be available next month.
