[SOLVED] B or M or both keyed?

[LGG]

I have a B450 Gaming Pro Carbon AC and i was wondering what the keying is on the M.2 slot. I have an MP510 ssd from corsair, is it compatible? Thanks.

Your SSD is compatible with that motherboard. The motherboard has a M keyed SSD, and typically M keyed can take M or B keyed. Your SSD is M keyed.

You don't have to worry about keying.
Your board supports

nvme drive in M2_2 slot and​

nvme or sata drive in M2_1 slot.​

MP510 is nvme and is compatible with your board.

ALTHOUGH... if you put it in M2_2 slot it will operate in PCIe gen 2 mode. That is a chipset limitation since all PCIe lanes provided by X470/B450 are Gen 2. Placed in M2_1 slot it will get full PCIe gen 3 bandwidth since those lanes come from the CPU so obviously it's preferred for a single NVME.

Also, but less important, any NVME put in M2_2 slot will probably 'steal' it's lanes from the second PCIe x16/4 slot so it will not be functional anymore. At least that's how MSI shared lanes on my B450m Mortar.
