AMD Company is determined to submit the AGESA version v1.0.0.6 package before the end of the month. The AGESA or AMD Generic Encapsulated System Architecture package is a microcode for the initial initialization of AMD Ryzen processors, which motherboard manufacturers insert into proprietary BIOS versions. At the moment the BIOS of most cards with Ryzen support use AGESA version 1.0.0.4. Version v1.0.0.6 is in active testing mode, but it is already available for Gigabyte GA-AX370-Gaming5 and ASUS Crosshair VI boards. The official distribution of the v1.0.0.6 package will begin just the other day, although the modified BIOS versions for the motherboards will be delayed until the middle or the end of June.
The main innovation in AGESA version v1.0.0.6 will be support for changed memory modes. This is done to improve memory overclocking and for its stable operation in modes that are not provided by the JEDEC DDR4 standard. A total of 26 important changes were made. Most of them relate to specific memory timings. Details on this can be found on AMD diary page. The most significant point was the support of memory up to DDR-4000 with a step of 133 MHz, starting with the standard DDR4-2667. Naturally, not all memory can work at this frequency, which AMD immediately warns.
In addition to changes in the operation of memory, which, incidentally, can now turn off the power after a certain period of inactivity, AGESA v1.0.0.6 supports PCI Express Access Control Services (ACS). ACS support allows you to manually distribute the resources of the graphics subsystem of the PC, for example, if the system has two video cards - discrete and integrated, between different virtual machines under Windows or Linux.
