Das einzige was mich beim ASUS MB etwas stört, ist die fehlende Debug Anzeige.
Ja, das ASUS B850 hat eine Debug‑Anzeige – aber eben die Q‑LEDs (CPU/DRAM/VGA/BOOT) und kein zweistelliges POST‑Code‑Display.
Lane‑Sharing haben alle AM5‑Boards, aber beim ASUS betrifft es nur die unteren PCIe‑Slots, nicht den GPU‑Slot.
Die GPU läuft also immer mit PCIe 5.0 x16. Für mich ist das ASUS daher die sauberere und bessere Lösung.
Beim Gigabyte X870 Elite wäre es anders, da geht die GPU auf x8 runter, wenn man den PCIe‑5.0‑M.2 nutzt – ist aber für eine 9070 XT trotzdem kein Problem.
PCIe 5.0 x8 entspricht PCIe 4.0 x16 und limitiert eine 9070 XT nicht.
Schau in Handbuch, dort findest du alle daten.
Expansion Slots 1 x PCI Express x16 slot (PCIEX16), integrated in the CPU:
AMD Ryzen™ 9000/7000 Series Processors support PCIe 5.0 x16 mode
* The M2B_CPU and M2C_CPU connectors share bandwidth with the PCIEX16 slot.
When the M2B_CPU or M2C_CPU connector is populated, the PCIEX16 slot operates
at up to x8 mode.
AMD Ryzen™ 8000 Series-Phoenix 1 Processors support PCIe 4.0 x8 mode
AMD Ryzen™ 8000 Series-Phoenix 2 Processors support PCIe 4.0 x4 mode
(The PCIEX16 slot can only support a graphics card or an NVMe SSD. If only
one graphics card is to be installed, be sure to install it in the PCIEX16 slot.)
Chipset:
- 1 x PCI Express x16 slot, supporting PCIe 4.0 and running at x4 (PCIEX4)
* The PCIEX4 slot shares bandwidth with the M2D_SB connector. The PCIEX4 slot
becomes unavailable when a device is installed in the M2D_SB connector.
- 1 x PCI Express x16 slot, supporting PCIe 3.0 and running at x2 (PCIEX2)
Storage Interface 1 x M.2 connector (M2A_CPU), integrated in the CPU, supporting Socket 3,
M key, type 25110/22110/2580/2280 SSDs:
AMD Ryzen™ 9000/7000 Series Processors support PCIe 5.0 x4/x2 SSDs
AMD Ryzen™ 8000 Series-Phoenix 1 Processors support PCIe 4.0 x4/x2 SSDs
AMD Ryzen™ 8000 Series-Phoenix 2 Processors support PCIe 4.0 x4/x2 SSDs
2 x M.2 connectors (M2B_CPU, M2C_CPU), integrated in the CPU, supporting
Socket 3, M key, type 22110/2280 SSDs:
AMD Ryzen™ 9000/7000 Series Processors support PCIe 5.0 x4/x2 SSDs
* The M2B_CPU and M2C_CPU connectors become unavailable when an AMD Ryzen™
8000 Series-Phoenix 1/Phoenix 2 processor is used.
1 x M.2 connector (M2D_SB), integrated in the Chipset, supporting Socket 3,
M key, type 22110/2280 PCIe 4.0 x4/x2 SSDs
4 x SATA 6Gb/s connectors
RAID 0, RAID 1, RAID 5, and RAID 10 support for NVMe SSD storage devices
* RAID 5 is only available on AMD Ryzen™ 9000 Series Processors.
RAID 0, RAID 1, and RAID 10 support for SATA storage devices
