什么是 PCIe 分叉/叉分/拆分/分拆 Bifurcation PCIe分叉是一种允许在PCIe插槽中划分数据通道的功能。 在支持的系统上,一个PCIe x16插槽可以被配置成两个PCIe x8通道,或更小的通道,这取决于主板的支持情况。PCIe分叉不影响整体速度,但允许一个较大的插槽像多个较小的插槽一样,允许使用一些先进的扩展卡,而无需额外...
同样,如果你想要PCI-e的设备,比如NVMe SSD满血,那么就不能插到板载那个M2 NVMe口,而是单独通过PCI-e转换卡插到SLOT1/3/6上面,因为那样子可以直连CPU,时延和性能都能最优。 另外,你也看到从CPU直接出来的PCI-e只有x16,那么如果你同时拥有x16的显卡,和x4的NVMe硬盘,那么就无法将两者同时最佳化,必须有所取舍。
ThinkStation P3 Ultra: Does it support PCIE bifurcation on the PCIe x16 or x8 expansion slots Does "ThinkStation P3 Ultra Workstation " support PCIE bifurcation on the PCIe 4.0 x16 slot expansion slot or on the "PCIe 3.0 x8 " slot?Quick...
1. PCIE X16 Slot Split 2 PCIEX8 (Physical Slot X16) 2. The motherboard BIOS is required to support changing the PCIE working mode of the corresponding slot to X8X8, and the motherboard models that are known to be supported are as shown below picture. ...

Based on the available BIOS simulator tool, I don't believe P330 Tiny supports bifurcation of the x16 slot intended primarily for use with GPUs. We never qualified a multi M.2 adapter for that slot, so this feature was not added or supported. Note that using a 3rd party adapter would st...

OP mentioned the 5000 series APUs may no longer reserve a set of PCIe lanes for their iGPU. Also, my mobo's specs page explicitly mentions the x16 slot's performance depends on the CPU: for 3000 G-series, it's 8 lanes wide (as you discovered on your own), but for the next-gen ...
