I am an owner of the MSI MEG Z490 ACE motherboard. https://www.msi.com/Motherboard/MEG-Z490-ACE/Overview When I bought the board about 15 months ago, I nstalled the Intel I5-10600k 4.1GHz processor, together with the Samsung 970 PRO 512GB NVMe M.2 (PCIe Gen 3.0). Since my motherboard did fully support the update to the “PCIe 4.0”, about two weeks ago, I “upgraded” my CPU to the Core i7-11700K Rocket Lake 3.6GHz Eight-Core LGA 1200 and also to the 980 PRO PCIe 4.0 NVMe SSD 2TB. I am aware and did quite bit of reading regarding that there is not such a dramatical change for the Z490 chipset, versus the Z590 but I still decided to do it. So here is my question: How do I know that my system is actually running in PCIe 4.0 now? When I pull up Samsung Magician 7, it seems to report that my 980 Pro is running in PCIe 3.0 mode. But when I pull-up CPU-Z, it’s telling me that I have a PCIe 4.0 computer. I am also showing here my CrystalDiskMark8 performance. The rest of my system is nVidia Super 2070 card, running Windows 10 x64. Any comments or advise is appreciated.
