Intel thế hệ thứ 11 có quá nhiều cải tiến nên chipset trên main phổ thông và trung cấp đời cũ không còn được hỗ trợAlong with the new set of processors, motherboard vendors will be launching a variety of 500-series chipset based motherboards for Rocket Lake, and these motherboards will also support current generation Comet Lake processors. These new chipsets have an x8 DMI link to the CPU, unless a Comet Lake is installed, then it is only x4. Similarly, Rocket Lake will also work in 400-series chipsets, and the Z490 motherboards that are advertised with PCIe 4.0 support should have this enabled through a BIOS update. There is one small caveat – Rocket Lake will not work in H410 and B460 motherboards as these use 22nm chipsets. There appears to be some incompatibility here.
