AMD Ryzen processors with the first version of the microcode AGESA, as we found out in the corresponding review, do not work very well with high-frequency DDR4 memory modules, especially if there are four such modules in the system, in terms of the number of connectors on most motherboards. The first update of the microcode AGESA brought a significant improvement in this sense, and the new one, which the company is currently preparing, having the version number of 1006, should go even further forward in terms of supporting various memory modules.
It is reported that more than 20 different sets of DDR4 memory will be recognized automatically, which means setting the optimal parameters. This is confirmed by information from GIGABYTE. The best memory for use with Ryzen is still the modules based on Samsung B-die chips, the largest suppliers of such DDR4 modules are G. Skill and GeIL. But Robert Hallock, the head of AMD's technical marketing department, said that the upcoming update of AGESA will make memory modules based on chips made by SK Hynix no worse than.
At the moment, there are entire guides on the network for choosing suitable memory for use in systems based on AMD Ryzen processors. In the lists listed in them, preference is given to peer-to-peer modules based on Samsung B-Die chips. It should be noted that the parameters of the majority of such modules are declared by the manufacturers in accordance with the specifications of Intel XMP, so the application of the declared parameters in the system with Ryzen can be a problem. In some cases, it is necessary to increase the memory supply voltage to 1.
5 V; It is also advised to increase the SOC / unCore voltage to 1.1 volts.
As for GIGABYTE, the representative of the company confirmed that the upcoming BIOS updates of motherboards of this manufacturer will also solve the problem of "soft brick", which can arise due to damage to the BIOS image file, and also allow manually disconnecting network controllers, audio interface and unnecessary slots PCIe. There are no exact dates, but this is the current month.
