Question Which slots for Dual Channel x570 Phantom Gaming 4

[M4TTH3]

Hi I have this motherboard and was wondering whether a1 and b1 were better as I see many photos of people placing it in those slots. Or a2 b2 which I currently have them in and they work fine. I was just wondering if the first configuration would be faster? I am using Corsair Vengeance LPX 16 (2x8) GB 3000mhz Sram

We suggest that you install the memory modules on DDR4_ A2 and DDR4_B2 first for better DRAM compatibility on 2 DIMMs configuration.
