February 24, 20233 yr Not sure if I have chosen the right hardware or/and I did not understood the whole topic about PCIe Lanes with a 11600K and this mainboard: Gigabyte Z590M GAMING X https://www.gigabyte.com/Motherboard/Z590M-GAMING-X-rev-10/sp#sp Here are my specs: - Gigabyte Z590M GAMING X - Intel 11600K - 2 x NVME WD SN700 (PCIe 3.0) - Nvidia GTX 1660 TI (PCIe 3.0) - LSI SAS2308 PCI-Express Controller (PCIe 3.0) I made a picture for better understanding: Here is the screen from the bios: As far as I know an 11600K is able to deliver 20 PCIe Lanes: https://ark.intel.com/content/www/us/en/ark/products/212275/intel-core-i511600k-processor-12m-cache-up-to-4-90-ghz.html So the rest is coming from the Z590 chipset? Is my configuration correct? I am fine running the controller at 3.0 X4 as there are only spinnig drives connected. Thank you for your help.

February 24, 20233 yr Author So my configuration is correct and all devices are running as shown in picture 1? And for further upgrades it will be possible to use the onboard SATA3 also?

Yes, but all the all PCH devices share the DMI link. 12 minutes ago, Civic1201 said: And for further upgrades it will be possible to use the onboard SATA3 also? With an NVMe device installed yes, it won't work with a SATA M.2 SSD installed on M2A_SB.
February 24, 20233 yr Author Perfect, thank you. I did not made a deep dive into DMI sharing but I think I will not run into a bottleneck. Solved
