Gigabyte and ASRock update X399 motherboards to support AMD Ryzen Threadripper 2000 Series
The first manufacturers to update the BIOS of the motherboards with X399 chipset for the second generation AMD Ryzen Threadripper have been Gigabyte and ASRock.
When the AMD Ryzen processors were announced and therefore the AMD Ryzen Threadripper, the company highlighted that the motherboards for the first generation processors (launched in 2017), will have a useful life until 2020, or what is the same, that the Socket AM4 (Ryzen) and sockets TR4 (Threadripper), supports all processors released until 2020, even if the number of cores increases and even if the lithography of the manufacturing process is changed. Well, ASRock and Gigabyte were the first to update X399 chipset motherboards to support the new second generation Threadripper processors.
ASRock and Gigabyte release new BIOS to support XNUMXnd Gen AMD Ryzen Threadripper
While ASRock and Gigabyte have been the first to release a new BIOS for their X399 motherboards to support AMD Ryzen Threadripper 2000 Series processors, it is expected that more manufacturers will follow suit. This update is based on the AGESA 1.0.0.6 microcode.
There are other manufacturers that have distributed beta versions with the commented microcode, released between May and June, but these are the first BIOS versions that we will call stable and that really offer support to the second generation Threadripper, waiting for them to arrive in the next weeks also versions of other manufacturers.
Along with these processors, it is expected with the arrival of the second generation Threadripper will also arrive new specialized motherboards with an unannounced chipset, but following the logic, it should be the X499. We don't really know if these new processors will add support for new technologies, quite possibly native support for PCIe 4.0.
