OCC_FrTeam March 9, 2021 News As we let you understand during our test of the MSI MEG Z490 ACE motherboard, the card seemed to be wired for PCIe 4.0 but without the possibility to use it with Comet Lake-S processors. MSI today announced new BIOSes for all MSI Z490 motherboards to provide PCIe 4.0 support with 11th generation Intel processors. So, as you can see, you will need to purchase an 11th generation processor. Then, you will just need to go through a simple upgrade to these BIOSes, which will therefore provide bandwidth and consistent performance for both M.2 SSDs and PCIe 4.0 graphics cards. The updated MSI Z490 motherboards unleash the full potential of peripherals. For your information, here is a table summarizing the BIOSes that are compatible with each motherboard model. What, you have a doubt about your BIOS flash? You can either use the compatible USB port if your motherboard allows it or refer to this article we posted on Vonguru. Even if it was a Godlike X570 model, the principle remains the same. Share On
