Product: HP ENVY 15t - AQ200 x360
Operating System: Microsoft Windows 10 (64-bit)
Hi All,
I have recently installed the samsung 970 EVO plus 500GB SSD in my laptop, but I am getting only half of the mentioned speed. I did check online and it seems for many people the reason is that PCIe 3.0 x4 was using 2 lanes instead of 4.
However, my laptop is using 4 lanes as per HWiNFO64. Please see the screenshots below. Do you guys know what could be going wrong here? Appreciate your help.
