This RAM uses dynamic random-access memory technology.
You have four HMA451U6AFR8N-TF RAM sticks from SkHynix for your Ryzen DRAM calculator. You noticed performance differences—running at 2666 MHz with all four installed and 3200 MHz when only two are used. This is likely due to memory controller limitations or how the system manages bandwidth. Your setup includes a Ryzen 3 2200G on an ASRock X470 SLI/AC board, which affects RAM speed stability.
It fits your motherboard if it works; otherwise it's likely an ECC chip.
I understand it's DDR4 and I’m not sure if you got my question right.
It probably comes down to how the motherboard is set up for RAM connections. A daisy chain layout on the PCB might make the second stick perform better than the first. Placing each stick in its own channel, using consistent speeds, helps ensure even performance. Or it could just be a matter of luck with the sticks and the memory controller.
Have you tried the Thaiphoon burner? It should provide the details you require for the Ryzen dram calculator.
