SSD install on XPS Studio 8000 ( no AHCI in BIOS )

Want to pick up a ssd for my XPS 8000. Noticing that there is no AHCI in the bios. Is there a way around this? I was hearing that I can set the BIOS to RAID and that will force AHCI. Is there any info on this? Thank you and Merry Christmas.

Hi Domchin,

Your system supports the use of an SSD (at SATA II speeds), but does not support AHCI.

Thanks Os, so it would prob not be a good idea to use an SSD in this machine? Since there is no AHCI, no trim is supported on the drive correct?

That I'm not sure about. It depends on whether the current RST supports TRIM under RAID. Can't say that I know the answer.

Will the bios put the SSD in AHCI if i set it to RAID?

The Intel RST will report AHCI if your drive is running in AHCI. You can check that now.

Hello

I have the same problem. I can't find AHCI in the BIOS

I want to install my intel SSD 520, 120GB

The Onchip SATA type only ATA of RAID (and not AHCI

What is the best option? ATA of RAID?

Ik have a Dell Studio XPS 8000, BIOS versie: A03, Chipset: Intel PCH P55

Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz (CPU:0)

Have you already installed your SSD? and what is the best option for the SATA type in the BIOS?

Hi Boes1001,

You definitely want RAID.

Hi Osprey4

thanks for your reply

i don't want RAID

I just setup in my BIOS SATA on RAID, but I couldn't startup my PC!  ;-(.

So I switched again to ATA, My PC runs now on my HDD and works.

I think I will not change SATA (now it is switched to ATA), and set my SSD to the SATA1 port and install my windows 7 on it. I hope I can set TRIM on afterwards,

You have to run the Microsoft FIX to switch to AHCI.

Go from IDE mode to AHCI mode for your SATA devices by running the Microsoft Fix It tool to enable AHCI driver support.

After running the MS Fit It Tool, reboot, enter the BIOS, change your controller mode to RAID AHCI, save the BIOS settings and reboot back into Windows.

Microsoft Fit It Tool – Enable Sata AHCI mode

After you use the BIOS setup of a Windows 7-based computer or a Windows Vista-based computer to change the Serial Advanced Technology Attachment (SATA) mode of the boot drive to use either the Advanced Host Controller Interface (AHCI) specification or redundant array of independent disks (RAID) features, you receive the following error message when the computer is restarted: 

STOP 0x0000007B INACCESSABLE_BOOT_DEVICE
