MSI 870-G45 bios unclear on AHCI mode??? Need Help.

[meat_loaf]

I have just bought a Kingston v300 SSD and I installed windows 7 on it without changing any bios settings. As I read a couple post about SSD that needs to be AHCI mode, I tried to do that on my mobo but the bios is unclear on the options.

Here is what my bios is on intergrated peripherals:
PCI busmaster (enabled/disabled) --> enabled
On-chip SATA controller (enabled/disabled) --> enabled
**with on-chip sata controller enabled I get the following option
RAID (IDE/RAID/AHCI) ---> IDE

But there is a major problem with it if I switch RAID to AHCI, because my bios won't detect there are any SATA drives and every thing is IDE. I also tried disabling PCI busmaster and still the same thing. So is my mobo one of those that automatically changes itself and I only need to enable ahci in windows registry??

Since I already installed everything into the SSD, is there a way to change in windows without the pain of reinstalling everything?

My bios is also the latest bios from MSI using AMI 10.9.

I have some bad news. You have an older motherboard that was released at the beginning of 2011. It does not properly support modern, 3rd generation, SATA 3 6Gb/s solid state drives which were released later. The motherboard only supports SATA 2 3Gb/s ssd's. In a best case scenario your motherboard might support your new ssd but at SATA 2 3Gb/s performance levels.

You will need to install the latest achi drivers for Microsoft Windows. You can download the appropriate achi driver for Windows here:

AHCI mode is a feature in a motherboard's system BIOS. It is part of the boot up process that happens before Windows starts up. Just go into the system BIOS immediately upon starting your pc and enable AHCI mode in the system BIOS. In addition, select the ssd as the primary boot drive in the system BIOS. That's all there is to it. No need to change anything in Windows. If you have Windows 7 or newer, the OS should recognize the system BIOS settings and load the correct achi drivers for Windows.

Yes, there is. For changing from IDE to AHCI: http://www.neowin.net/forum/topic/987378-how-to-switch-from-ide-to-ahci-without-repairingreinstalling-windows/

You'll need to make these changes in Windows BEFORE changing the BIOS SATA mode to AHCI.

Just another quick question, what does RAID do (wiki didn't help as im not that familiar with RAID)? From what I've raid it increases performance by using all ur drives as one logical unit. I'm only asking because i want to keep all the programs and software that i use on the SSD and HDD as a storage. So I dont want to happen to find if I install things my SSD is creating some logical backup in my HDD.

Anyways guys thanks for your help, though I notice anything different so far switching from IDE to AHCI in terms of boot speed, but certain applications did get a bit faster.

Glad to hear that you got it to work. Thanks for the feedback.
