ROG B450-e wifi

[CaptainSpeedster]

Hello, i am planning on buying rog b450-e but i have 2 things im not sure about,

when i put the m.2 e key for wireless device support does that take any preformance from first PCIe slot

and 2nd question is if m.2 is using sata mode (m.2_1 in this scenario) it will only disable sata6g_5/6 ports, not effect preformance?

Thank you

nope, it connects to the chipset not CPU. That said, I will score this against Asus because there clearly is space to put WiFi into the rear I/O.

yes but you should use M2_2 first unless you need the extra PCIe slot

Thanks,

but about the second thing,in the manual it says "When the m.2_2 is occupied by m.2 device, PCIe x16_1 will run at x8 mode" ,doesnt that mean that it will only use first 8 lanes?

I meant "could", not should, if you want the extra SATA ports. Unless you have a really high end card (of which you wont be considering this board at that point) PCIe 3.0 x8 is enough for the graphics card

I have a 1060 8Gbps version so yea it doesnt need the x16 but i have only 2 sata devices so if the preformance is the same on both m.2 slots id rather use the m.2_1.

Thank you very much.
