" rel="nofollow - Hi

Recently bought an Z370 Extreme 4 motherboard and after finishing Win 10 install on my Samsung 960 Evo nvme m2 drive, i'm experiencing problems with extremely slows speeds.

For example extracting a zip file (approx 200 mb) to a folder on the same drive, takes several minutes comparing to my last system which cointained the same ssd (intel z97). The extraction also freezes and halts my pc, speeds fluctuate below 10 mb/s.

No other sata drive is connected, and i've installed drivers (inf, intel me, rst) and also the samsung nvme driver. SATA mode is ACHI gen 3.

Samsung Magician also reports PCie gen 3 x4. I've made a fresh install in both m2 slots, currently in m2_2. The problem is also evident with no samsung nvme driver.

Any tips? CPU is 8700k and 3200 mhz ddr4, 750W psu, no overclock. Tried loading uefi defaults.
