[SOLVED] Wich slot to use for GPU and wich for Nvme ssd? Any difference?

[Margaret_All]

Hey friends, here's an image of my mobo.: AsusTuf gamin x570 plus
It has 2 PCIe slots (1 and 2 in light blue) and 2 M.2 slots (1 and 2 in red), I'll be adding one GPU (Sapphire R7 240 1gb ddr5) and one Western Digital Blue SN500 NVMe (PCIe) 250gb, so I'm wondering wich of the two slots should I use for the GPU and which of the two for the SSD?

Or it doesn't make any difference?

Should I worry at all about the "PCIe lane usage" of both devices?

Thanks so much!

GPU on 1
NVMe on 2

NVMe on 2

Thank you! Any particular reason to do it that way? So I can learn

GPU on 1,
SSD on M2_1

Both of thee connect directly back to the CPU for full speed. Everything else connects back to the x570 chipset.

With a 3rd gen Ryzen CPU the PCIe slot 1 (top) runs at 16x PCIe 4.0 speeds.
Also, the PCIe slot 1 has a metal reinforcement to support the weight of GPUs.

You might not see a difference in performance using that WD Blue NVMe if you place it on any of the slots. But NVMe gets hot while running, that's why Asus included a heatsink on that slot...where it will run cooler.
A NVMe running hot will reduce speed to cool down.

Actually the controller on the NVME prefers to keep cool, the flash chips need to get warm/hot to run at full speed.
