Question Is my ram in the right slots on my motherboard?

[MadScientist]

I purchased 2 kits (4 sticks) of this ram, 32Gb total, CORSAIR Vengeance LPX 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3600 (PC4 28800) for my Asrock B550 Phantom Gaming 4 motherboard. Yes, DA me went for the sale price of $60./kit before checking the ram compatibility chart for this MB on Asrock's website. I'm currently running this ram at 3200 Mhz. (see my last post in my build thread). System Information Viewer says they are SR ram and one kit is manufactured by Samsung the other by SK Hynix.
I have the Samsung ram in slots A1 and B1 and the Hynix in A2 and B2. The board will support 3200 Mhz ram in all 4 slots. According to the chart in my manual is this correct or does it matter with 4 sticks?

From my MB manual:
Installing Memory Modules (DIMM)
This motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots, and supports Dual Channel Memory Technology.
1. For dual channel configuration, you always need to install identical (the same brand, speed, size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one or three memory module installed.

The way you have it installed should be correct - one set of matching modules in A2 and B2, the second set of matching modules in A1 and B1.

Thanks, I thought they were in the right slots. Got used to the color coded slots.
