It runs at x8/x8 if two slots are populated.

Hi,
You might check which mode your m.2 is in and possibly switch m.2 slots used.

For what I know this moba can handle 2 m.2 with the 16x in the gpu , for change it have to empty the water cooling system , it’s a pain in the ... before doing it want to be sure

Any hint ?

Hi,
I returned a z490 formula for a z490 apex for a few reasons but most was the lame m.2 layout
2nd was this platform does not need a vrm water block.
3rd memory oc is better on apex.
4th saved 100.us :)

Using a M.2 NVMe SSD shouldn't affect the 1st slot. Usually just on cheaper boards it could disable some SATA connectors but that's not the issue here.

I asked to ASUS to help me and they said the cpu has only 16 lanes , and using a nvme I’m using 4 lanes from those 16
Hm, what CPU is that?
And if that's the case, just move the SSD to the other M.2 slot.

I'm using a z390-f and have 2x PCIe M2 and gpu is still at 16x using both M2 slots. I have sata controller disabled in the bios though if that makes a difference.

Yeah, OP's right. Z390 would be 9th gen Intel, and they're limited to 16 lanes according to ARK. So using a CPU-connected M.2 slot will turn the GPU to x8 mode. If you've got more than one M.2 slot I'd suggest using another one, OP. Check the manual to see which ones are connected to the chipset, use them.

Hi,
You really haven't showed any proof you're running at x8
Use gpu-z and at least show a screen shot saying it is

Hi,
That would be nice because you saying it just is not enough anymore.
Screen shot I show is just too darn easy to show.

Make sure there is a load on the GPU when you get the screenshot or all we'll see is the card on idle.

how could i tell if my M2's are using cpu or chipset PCIe lanes? as i have 2xPCIe M2's and GPU is still at 16x My CPU is 9th gen so i am assuming only 16 lanes as someone stated up there ^

x16 1.1? Is this under load? If that's under load, something's wrong. That's the equivalent of 4x 3.0 lanes in bandwidth, which would severely hamper the performance.

It clearly states "It is currently running at: PCI Express x16 v1.1" in that red box in the picture. Although that might just be power saving at idle
