Good day. The Asrock x570 Phantom Gaming 4 has 2 PCIe 16x connectors. Can I use both at the same time with full speed? I know from other models that the two connections are reduced to 8x when they are both in use. I want to install an Asus Hyper M.2 X16 Card (4x M.2 SSDs trough PCIe 16x). How will this affect my 2 M.2 SSDs installed directly on the motherboard? (see specs) Information to the other PCIe 1x connetcors would be nice. What SATA ports (1-8) should i use for this configuration; wich don't affect the PCIe lanes? Sys Specs: CPU: AMD 5800X (has 24 PCIe-Lanes) Ram: 32GB (2x 16GB) ADATA XPG Gammix D20 Gfx: GTX 1060 (will be changed soon to a newer) 2x M.2 on mainboard: Crucial P2 CT250P2SSD8 (1 sys, 1 apps) will be changed to Nvme 1.4 (PCIe gen 4) later 2x Sata SSDS (games), 2x Sata HDDS (music/movies/data), 1x DVD Thanks in advance |

No, your PCIe1 slot is x16 and the PCIe3 slot is x4. Though PCIe3 is physically an x16 slot it is electrically wired as x4 and is provided it's PCIe lanes from the X570 chipset rather than the CPU.
The top most x16 slot will operate at x16 with a 5800x and the lower x16 slot is limited to x4. The lower slot is however PCIe 4.0 so performance wise it will have nearly identical performance to a PCIe 3.0 x8 slot. If you plan to use high speed PCIe NVMe drives (PCIe 4.0) then I would put your Hyper M.2 card in the top slot and your 1060 in the lower one. The PCIe 4.0 x4 lower slot will not bottleneck a GTX 1060. If you are planning on getting a new GPU that is faster than an RTX 2060 then you will want it in the top PCIe x16 slot. I am not sure about the specs of the Hyper M.2 card or it's requirements but I wouldn't use one with your board unless you can give it the full x16 lane slot. The x570 Phantom Gaming 4 is on the budget end of ASRock's X570 lineup. You would ideally want a higher end board with 3 x16 slots but even then, you would likely be limited to x8 + x8 with 2 slots in use using PCIe x16 unless you use the lowest x16 (x4) slot for your GPU. This is why HEDT (High End Desktop) systems have so many more PCIe lanes. X399 TR40 etc. -------------

Did you figure this out? When I tried running an nvme drive in an expansion card in the lower pci slot it disabled my LAN port on the x570 phantom gaming 4. |

It depends on the CPU you are using. As you said:

Bikergofas: As Xaltar answered, its not a good idea to use this extension card, if i upgrade my GFX, the Myper M.2 card will only run at 4x speed. Anyway, do anyone knows, wich SATA ports go directly to the chipset and wich go trough PCIe lanes? |

all sata ports goes to chipset pcie lanes cpu has sata controller aswell, but that is usualy wired for m2 sata slot if you need more x16 lanes, then you may want to look for other platforms like sTRX40 https://www.asrock.com/mb/AMD/TRX40%20Taichi/index.asp" rel="nofollow - trx40 taichi ------------- http://valid.x86.fr/diq4l4" rel="nofollow">  http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |
