Hi,
I have a MSI Godlike X99A with a 6850K CPU that I have modded to allow bifurcating the last PCI-E Slot on the motherboard in half from 8X to 4X4X operation. Such that with an adapter like the Supermicro RSC-R2UU-2E4R 2U PCIE I am able to run my onboard M.2 at 4X speed along with a Plextor NVME x4 drive on the last PCI-E slot at the same time where as before it was not possible to without setting the M.2 to PCH Mode. Anyhow the problem is sometimes when I boot up HWinfo says the current link speed for the Plextor is 2.5 Gbps where as sometimes its a 8.0 Gbps. I noticed that my video cards sometimes do the same thing until they are put under load so I wonder if its something similar? Got link state power management disabled in Windows power plan settings as well.
So I'm a little confused on whats going on:
