Nun schafft AMD -endlich- Klarheit: Auf AM4-Mainboards mit dem Chipsatz X470, B450, X370, B350 und A320 wird es keinen PCIe-4.0-Support geben.
Demnach wird man PCIe 4.0 nur in Kombination mit einem neuen X570-Mainboard und AMD Ryzen 3000 Prozessor geboten bekommen.
Offiziell heißt es:
"This is an error we are correcting. Pre-X570 boards will not support PCIe Gen 4. There's no guarantee that older motherboards can reliably run the more stringent signaling requirements of Gen4, and we simply cannot have a mix of "yes, no, maybe" in the market for all the older motherboards. The potential for confusion is too high.
When final BIOSes are released for 3rd Gen Ryzen (AGESA 1000+), Gen4 will not be an option anymore. We wish we could've enabled this backwards, but the risk is too great.
