Hi, i have a z270 a and i was wondering which PCIe lane are connected to the CPU and which are to the chipset.
Unfortunately the manual says nothing at all.
I'm currently at 13 GPU, but i want to get more on the board. I know there are a few lanes left, gotta found them.

Anyone that knows how the lanes are split?

Chipset Z270 has 24 lines of PCI-E and other lines depend on the processor. M.2 SATA are connected to the chipset.
The following shows the hardware connection (top to bottom):
PCIe 3.0 x1 x1 (Z270)
PCIe 3.0 x16   x16/x8 (CPU)
PCIe 3.0 x1   x1 (Z270)
PCIe 3.0 x1   x1 (Z270)
PCIe 3.0 x16   x8 (CPU)
PCIe 3.0 x1   x1 (Z270)
PCIe 3.0 x16   x4 (Z270)

Perfect. Thanks
Til now i had 2 1 to 4 pcie connected to these:
PCIe 3.0 x16   x8 (CPU)
PCIe 3.0 x1   x1 (Z270)
OFC i wasn't able to get over 13 GPU. I'll test by moving the second to the
PCIe 3.0 x16   x16/x8 (CPU)
Will i be able to get to 15?
Anyway, i have a GPU in the PCIe 3.0 x16   x4 (Z270) slot without a riser, should i use a riser with that too?
Then i'll try by having a 3rd 1to4 to one of the 2 1to4 and i'll try to get to 18.
Seems reasonable, right?

Do you know what other hardware use some PCIe lanes?
I know for sure about the USB 3.0 hub and board graphics (deactivated). What about all the other usb ports, sata connectors, rgb, ram, etc...?

On page 1-8, there is a resource sharing table (IRQ). ASM2142 uses 2 lines of PCI-E. Other connection options you can check yourself.

I saw that table but wasn't able to get any other info. How can u tell how many lanes are used andif from cpu or chipset?
