Hello, i bought a ssd few days ago. All drivers and bios up to date and i've tried so many things. I couldnt find the solution.

The problem is my pc support Sata3 and usually after restart or opened the pc i'm opening test program s to calculate speed. Somehow i can see over 500mb/s speed. But after i play some games and then im testing again.
The speed is sata2(~200mb/s), and also i can see the sata2 warning in SSD's program and HWInfo program.
