Enabling AHCI on Asus P5K?

Tim1981 · 2 Dec 2011 at 23:55

Hi there, I have recently ordered a 120 gb SSD drive to replace my current hard drive.
I have been told to change my bios configuration from native IDE to AHCI to increase performance on the SSD.

I will be running a clean install of Windows 7 (64) and at present have no option to change the bios to AHCI mode with my current hard drive.The only option I get is IDE.

Is there a way I can get my new SSD running In AHCI on a P5k?

Any help, much appreciated.

Thanks for the quick reply's.Yes I am very familiar with the bios and realize how to change the option, but the only option I have there is IDE.That is the reason I have posted this thread.

The only option I have for AHCI in the bios is under the advanced tab in Onboard Device Configuration Controller, mode section.There I can choose from either ide, raid or AHCI.

Will it have the same desired effect on my new SSD drive if I change this option instead or is this for something different.

Many thanks for the help.

Yes sorry that was for the Jmicron controller so i'm back to square one.Do you have any idea why i am not getting the option to change my drive to AHCI?

Thanks again for your help.Am I going to notice much performance difference on my old mobo if i run the ssd in IDE?

Cheers Surveyor for your time on this.I now have the SSD installed as my OS boot drive and my old hard drive is reformatted for storage.

I have already noticed differences in boot times especially just after the desktop loads on my old HD it would take a while for programs to load, but this thing is instant.

I have not tried it yet but I was hoping it would clear up the odd stutters I get whilst playing PC games/simulators.

Its mainly for IL2 Cliffs of Dover and a few other games.Ill look at upgrading my ram soon.I have 4 gig Ram.

Here is Atto's SSD benchmark results for it.Thought I would check how hampered I am running in native IDE.
What sort of read and write speeds would you be getting on a normal 7200rpm drive like the one I upgraded from?

So these speeds arent too bad then?

The SSD helps a lot in games it seems.BF3 and Cliffs of dover are running very smooth with 6950 and 3.2 quad.
