My motherboard ASUS Z790 WIFI F bios 0904 has weird issue.
When SSD NVME is insert in socket M2_1 the speed of Samsung 990 2TB Pro has only speed x2 and and there is no x4
When the same ssd is in socekt M2_2 it has full speed x4
The other 1 x drive HDD is plug in sata
I713700K - system no overclocking
2 x 16GB ddr5 7200Mhz - no overclocking
i tested everything 🙂 reset bios, plug off RTX 4090, plug ofd sata, diferent bios config, turn off wifi and sata and no luck
You might want to keep the nvme in the M2_2 slot anyway as the 4090 will only run 8x with it in M2_1.
No, that's incorrect for the Strix Z790-F. M.2_1 does not take GPU lanes on that board; it uses the dedicated x4 storage lanes from the CPU, which are higher performance than the chipset M.2 slots (M.2_2, M.2_3, and M.2_4).
