Question Need help on MoBo & RAM technical

[ravcross]

hi experts, i just bought a rig, but I'm not sure of those technical parts such as single channel ram / dual channel ram & the layout of the mobo..

what i have:

CPU: Ryzen 7 (Pinnacle Ridge)
Mobo: Asrock B450 Pro4/A
RAM: Corsair Vengeance LPX 8GB (1x8GB) 3000MHz C16 Memory Kit (2 units)


i plan to install 16GB of RAM..In the mobo layout, i have 4 ram slots - A1 A2 B1 B2..for pinnacle ridge, the manual is as below:

1st question:

does that mean i need to slot into slot A2 & B2 respectively to get the highest clocked RAM?


2nd question:

i bought 2 individual sticks of RAM - Corsair Vengeance LPX 8GB (1x8GB) 3000MHz C16 Memory Kit (CMK8GX4M1D3000C16). so if i slot 1 piece into slot A2, the ram is recognized as 8GB single channel RAM? and if i slot another stick of RAM into B2, does that make it into 16GB dual channel RAM?

3rd question:

i just noticed that there is a Corsair Vengeance LPX 16GB (2x8GB) 3000MHz C15 Memory Kit (CMK16GX4M2B3000C15R). Is it different if i use 2 units of individual 1x8GB RAM vs the 2x8GB memory kit?

Thank you in advance.
