I am getting slow SATA connections with E5-411G

I am having problems with my new laptop supporting SATA speeds of 6Gb/s. Any drive attached will only connect at 3Gb/s. Even if the drive has support for 6Gb/s.The drive speed issue is occurring in both Windows and Linux. So I don't see a driver issue. The interface is supposed to support 6Gb/s but I am not seeing it.

Acer Aspire E5-411G-P647

Intel(R) Pentium(R) CPU N3540 @ 2.16GHz

Motherboard- Acer EA41_BM Insyde Bios v1.12

8 GB RAM

Intel Valleyview SoC - SATA AHCI Controller [C0]

Drive Controller: Serial ATA 6Gb/s @ 3Gb/s

As you can see from the info above The drive controller is showing Serial ATA 6Gb/s @ 3Gb/s. With the supe lockdown on BIOS, I have looked as far as I can. How do I fix this problem?

When you say "drives attached", are you talking about USB 3.0 drives or are you talking about a drive in an HDD enclosure?

My HDD drive in my USB 3.0 enclosure links at 6 Gb/s and my seagate USB 3.0 drives link at 3Gb/s. I think that's normal. But then again, I've never really thought about it. I don't have your computer. I have a desktop.

I'm using a Vantec Nextar for enclosure.

Edit: I don't know why my seagate USB 3.0 drives shows 3Gb/s link speed when they operate at higher speeds than SATA rev. 2.0 when I look at file copy speed. A mystery.

What drives are you using? HDD? SSD? Microsoft AHCI?

Not using USB in any way. Direct to motherboard SATA connection. HDD or SSD doesn't matter. Same conection limitation. Same speed in Linux, so drivers are not the problem. Problem has to be in BIOS/UEFI settings or the motherboard itself.
