That statement was made almost two years ago, when the only PCIe x4 support was on AMD systems. While that's no longer the case (the current Intel platform does support PCIe x4), it still applies for older systems like the M15 R1.
What is the model system you've posted the photo for (it appears to support PCIeX4)?

ejn63,
It looks like he is referring to the 2019 m15 R1 specifications PDF, page 14.

Confusion based on the specifications.
PCIe 4 x4 is the current (i.e., a PCIe4 drive) fastest.
PCie 3X4 is the older standard (the one this system supports).
Current Intel systems do support PCIe 4 x4 -- older ones like the M15 R1 did not.
You can run a PCIe 4 drive in the M15 R1 -- but not at full rated speed.

Thank´s for all responses. I have it clear. Someone knows what bios is possible to undervolt? I have a 2.13 and temperatures are in 100ºc.
