Efficient motherboard. Allows the computer to boot without any issues and to accommodate DDR4 memory and storage
Always top-quality service as usual, with a team that is more professional than sales-oriented, a rare quality nowadays.
Works with an AMD Ryzen 5 5600GT processor.... No need to update the BIOS despite what is written on the box (thanks to the technical support team for the information and advice). Ubuntu Linux installed without any problems.
