Title: ASUS Prime z270-A , PCIe lanes division among CPU and Chipset Post by: ElMinator on February 18, 2018, 07:59:39 PM 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? Title: Re: ASUS Prime z270-A , PCIe lanes division among CPU and Chipset Post by: Amstellodamois on February 18, 2018, 08:03:52 PM Following

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) Title: Re: ASUS Prime z270-A , PCIe lanes division among CPU and Chipset Post by: ElMinator on February 19, 2018, 12:11:26 AM Hi, i have a z270 a and i was wondering which PCIe lane are connected to the CPU and which are to the chipset.

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...?

Other connection options you can check yourself. https://i.imgur.com/3Qfg1DJ.jpg Title: Re: ASUS Prime z270-A , PCIe lanes division among CPU and Chipset Post by: ElMinator on February 19, 2018, 10:38:24 PM Hi, i have a z270 a and i was wondering which PCIe lane are connected to the CPU and which are to the chipset.

How can u tell how many lanes are used andif from cpu or chipset? |
